    Description: The physical and chemical characteristics of freshwater bodies Ikot Ebak and Abeneyentem streams in Essien Udim Local Government Area, Akwa Ibom State, Nigeria were studied from (July December 1996). The mean values obtained in the two water bodies were pH (6.8~c0.12, 6.8~c0.09, respectively). Conductivity (4.9~c2.26, 5.0~c2.09 iScm-1), total dissolved solid (16~c7.58, 37~c26.9 mg/l), TSS (46~c26.0, 53~c53.1)g/l), alkalinity (17.5~c7.27, 10.7~c8S MgCaCo3/1), DO (6.98~C1.46, 8.3~C29.0mg/1), BOD (2.65~c2.44, 3.15~c2.79mg/1), Salinity (0.41~c0.12, 0.31~c0.04%o') total hardness (0.64~c0.21, 0.84~c0.42mg/l, N03-N (0.31~cO.26, 0.35~c0.29mg/l), and PD4-P (0.022~c0.0199 0.023~c.022mg/1), respectively. There were significant difference in the means of the parameters in the two water bodies except TDS, Alkalinity and Hardness. The water bodies were found to be slightly acidic with low conductivity. The properties in the water bodies were in conformity with international standards for both drinking and aquatic life.

    Description: The objective of this study was to determine the best smoking method that will enhance consumer preference for Clarias gariepinus without affecting negatively the nutritive value. Two methods of smoking were used: cold and hot smoking. The fish were smoked with improvised drum smoking kiln and oven. Smoked fish samples obtained were subjected to chemical analyses and sensory evaluation. Chemical analyses showed that the smoked fish were still rich in protein (66.0067.52%) and fat (9.83-12.28%); while the moisture content ranged between 7.82-8.24% and ash, 12.86-14.16%. There was no significant difference (P〉0.05) in the protein, ash and moisture contents. Significant differences (P〈0.05) were observed in the Calcium(Ca), Potassium(K), Sodium(Na), Zinc(Zn), Lead(Pb), Iron(Fe) and Phosphorus(P) contents. Only hot smoke-dried (HSD) fish samples showed no presence of lead. The levels of sodium(Na) and potassium(K) in the smoked fish were relatively high, though, the amount of potassium(k) was higher. Sensory evaluation results revealed that there were no significant differences (P〉0.05) in the colour and taste ratings of the smoked fish samples. However, significant differences (P〈0.05) were observed in the odour, texture and overall acceptability. Hot smoke-dried and cold oven-dried Clarias gariepinus had the best overall acceptability in ratings.

    Description: Metrological parameters and their impacts on weight loss of fish inside Kainji Solar Tent Dryer were experimentally investigated. Drying experiments were conducted in solar dryer across the five agro ecological zones of Nigeria. During the drying experiments, the parameters such as temperature, relative humidity were lowest. The study showed that meteorological parameters were the primary determinants for fish drying within the Kainji Solar Tent Dryer, since weight loss during the experiment followed the pattern of these parameters

    Description: In recent times there has been an upsurge in the culture of Tilapia in Nigeria resulting in increased demand for the fingerlings which is hardly satisfied. This is due to increasing demand for table size tilapia as food fish and under-sized tilapia in the fish meal and fish canning industries in Nigeria. Collection of Tilapia guineensis fingerlings from the wild, to augment hatchery production, has been the practice and this is subject to environmental fluctuations. Multivariate regression and correlation analyses of accumulated data were used to investigate the effects of changes in water quality parameters on abundance of fingerlings of Tilapia guineensis in a brackishwater habitat in Lagos. Dissolved oxygen (DO), salinity and secchi transparency were found to be the most dominant factors affecting the abundance of Tilapia guineensis fingerlings in the Lagos lagoon. Peak period of abundance was closely associated with period of low salinity (0.50%o to 5.60%o), which coincided with the period of low transparency and low DO in the rainy season. The correlation analyses of Tilapia guineensis fingerlings with the water quality parameters yielded the following correlation coefficients (r)- 0.598; (salinity); -0.644 (transparency); -0.710 (DO); -0.566; (temperature) and 0.129 (pH). The abundance of Tilapia guineensis fingerlings in the Lagoon was ultimately defined by a suitable regression equation. This result is expected to optimize the collection of fingerlings of Tilapia guineensis from the wild and boost food fish security in Nigeria and elsewhere.

    Description: Spatial and temporal variations of physico-chemical variables of Onu-Iyi ?Ukwu stream were studied for 12 months from March 2005 to February 2006. Three sampling stations were established along the main stream channel from source to mouth. Spatial variation in physico-chemical parameters indicated that total alkalinity, total hardness, conductivity, and nitrate-nitrogen (NO3) recorded their highest values at the upper reaches (with values 14.0mg/l, 88.09mg/l, 17.00~kscmiscm, and 0.60mg/l respectively). Dissolved Oxygen (DO) and pH had their maximum values of 8.20mg/l and 6.94 at the middle reaches. Turbidity, biochemical oxygen demand (BOD), temperature and phosphate-phosphorus (PO4) increased steadily from source to mouth. The observed seasonal variation indicated that wet season values were higher for all the parameters except temperature, turbidity, phosphate-phosphorus (PO4) and total alkalinity although the values were not statistically significant at p〉0.05. The correlation coefficient (r) showed no significant relationships p〈0.05 between physico-chemical parameters except DO and BOD with correlation values of (0.75 and -0.54) respectively.

    Description: The physico-chemical parameters of Bosso Dam were analyzed weekly for a period of six (6) weeks from 29th October, 2009. In all, six (6) stations were identified within the dam. The physico-chemical parameters assessed were: temperature, dissolved oxygen, pH, alkalinity, hardness, conductivity and transparency. The results obtained from the analysis revealed slight variations in most parameters. There was no significant difference p〉0.05 in pH regardless of stations and weeks. But significant difference p〉0.05 were observed in dissolved oxygen, nitrate, temperature, conductivity, hardness, alkalinity, biological oxygen demand, transparency, in respect regard to stations. These variations could be due to influx of organic waste from surface run offs and inorganic waste deposited by man. The physico-chemical parameters observed, indicated that most of them fall with the recommended range or standard by the Federal Ministry of Environment

    Description: This study evaluated the effect of varying smoking durations of 6, 6.5, 7 and 7.5 hours on the microbiological quality and percentage moisture content of cold-smoked Atlantic Cod, Gadus morhua. The fish sample were cold-smoked using the traditional drum oven. Four batches of the smoked fish were stored in metal baskets at ambient temperatures for a period of 12 days and assessed for Staphylococcus aureus and Escherichia coli loads, Mould count, Total Plate Count and Total Coliform Count. Analyses of the smoked fish samples were carried out at the initial stage (day 0) and subsequently every alternate days (i.e. days 2, 4, 6, 8, 10 and 12). Significant variations (P 〈 0.05) were obtained for all the microbial counts on the four smoked fish samples. The best microbiologically stable cold-smoked samples were that smoked at the longest duration of 7.5 hours. This produced the least mean microbial load range of TPC (1.50 x 103 - 2.00 x 105cfu/g); TCC varied from 0.0MPN/g to 12.0 MPN/g ; Mould count (1.32 x103 - 2.55 x 105 cfu/g) and Staphylococcus aureus (3.0 x103 - 1.35 x 105cfu/g) while percentage moisture content ranged between 25.3% to 15.2%. All the samples tested negative to Escherichia coli.

    Description: The paper examined gender and fisheries of Lake Kainji, Nigeria. The study highlights socio economic characteristics of women involved in Kainji Lake fisheries, important issues about gender and fisheries. It reveals that the categories of women in the Kainji Lake fisheries are in the middle age of 31 to 40 years with very low educational background. It also indicates that fish processing has been the most prominent activity of women in fisheries of Lake Kainji and constitute about 60 percent of the women. The study concludes that women play significant roles in all aspects of fisheries in Lake Kainji. Importantly, women’s roles span reproduction and production.

    Description: Staphylococcus aureus is a common organism on the skin and in the nasal passages of approximately 50% of the population. Heat-treated seafood may become contaminated with this organism by poor handling, then storage at improper temperatures allows the organism to multiply and produce its toxin. This type of food poisoning may be avoided by practicing strict personal hygiene, thorough cleaning and disinfection of equipment, and storage of susceptible food at temperatures below 10°C or above 60°C. Presented in the paper is the methodology of determining S. aureus in fish and fishery products.

    Description: Streptococci are gram-positive cocci, sometimes coccobacilli, arranged in chains. This group of streptococci resides in the intestine of warm-blooded animals. They are bile resistant and capable of growth at 45°C. Fecal streptococci form part of the microflora of many foods without necessarily indicating poor hygiene. They are found in many fermented foods, such as cheese and raw sausage, and often take part in the fermentation process. However, in meat products which have received a severe heat process, the presence of excess numbers of fecal streptococci indicates unhygienic handling and/or faulty storage. Presented in the paper is the methodology of determining the presence of fecal streptococci in fish and fishery products.

    Description: The physico-chemical and biological characteristics and nutrient concentration of Kigera Fish Farm ponds were monitored for two months to assess the water quality. The parameters measured were dissolved oxygen, temperature, hydrogen ion concentration, Secchi-disc transparency and zooplankton composition. Some fish species were identified in the course of study. Temperature ranged from 26 -30degreesC; dissolved oxygen ranged from 3mg/l-6.6mg/l, pH ranged 7.0 -7.2; while Secchi-disc transparency ranged from 0.19 - 0.25m. The three ponds were quite similar in these parameters. All the parameters that were investigated in this study are within the tolerable level for warm water fishes. Five different zooplankton species were identified at the Kigera Fish Farm, and were grouped according to their major categories namely: Copepods, Cyclopoids and Copepodite), Cladoceran (〈i〉Moina〈/i〉), and Rotifera (〈i〉Asplanchina〈/i〉). 〈i〉Branchionus〈/i〉 species in the Rotifers group dominated the zooplankton species in all the three ponds.

    Description: Frozen surimi has been a major export fishery product of Thailand for many years. Approximately 70% of its total production is exported to Japan, while the remaining is locally used and exported to France, Korea, Taiwan and Singapore. Although surimi is not categorized as a high risk item, as it is not a ready-to-consume product but prepared to serve as a raw material for a variety of surimi-based products, it still needs to meet the minimum requirements of product safety control. In this study, the quality assurance program is established for the Thai surimi industry. The guidelines are prepared and based upon risk assessment and potential health hazard identification associated with routine surimi production, from the point where raw material is received at the plant, through the line processing steps, and ending with the finished product s transportation. Besides the Hazard Analysis and Critical Control Point (HACCP) principles applied in this program, Good Manufacturing Practices and sanitation standard operating program are also added to strengthen the aim of assurance in food safety.

    Description: Lizardfish, Saurida tumbil, is an abundant resource that is relatively underutilized. It is a potential raw material for surimi processing. Characterized by its ability to produce formaldehyde endogenously after catch, the lizardfish tends to have comparatively higher levels of formaldehyde, which is known to accelerate protein denaturation. As such minced meat from lizardfish has to be treated to enhance its gel-forming ability. The objective of this project is to improve the gel-forming ability of surimi made from fresh and frozen lizardfish by sodium pyrophosphate leaching (PL), and the use of egg white and beef-plasma protein concentrate. This was compared against the usual leaching (UL) method. Pyrophosphate leaching (PL) resulted in better gel-forming ability. Two-times of leaching using 0.2% sodium pyrophosphate resulted in the production of reasonably good quality fish jelly products from fresh and frozen lizardfish. Both egg white and beef-plasma protein concentrate improved the gel-forming ability of surimi from lizardfish. However, if the frozen raw material is of poor quality, neither pyrophosphate leaching nor the addition of egg-white or beef-plasma could improve the gel-forming ability of the surimi. The critical control point for raw material quality is its formaldehyde level. The best quality surimi is obtained when the formaldehyde level is below 15 ppm.

    Description: An experiment was conducted to determine the efficacy of pepper and garlic spice mixture at 0%, 2%, 3%, 4% and 5% levels (per gram of fish) in retarding lipid oxidation and on the organoleptic quality of hot-smoked catfish (Clarias gariepinus) in Kainji Area. The fish samples were frozen, cut, eviscerated, cleaned and dipped in 14.5% brine for 10 minutes. They were treated with the spices, smoked at 80-86~'C for 6 hours, cooled, stored at room temperature (25~'C-31~'C) for 21 days and used for physical, chemical, microbial and sensory evaluation studies. Untreated samples served as control. From the results of analysis, samples treated with the mixture of pepper and garlic paste (1:1 ratio) were microbially more stable than the control samples as these had longer shelf-life and were not visibly covered by moulds during a 21-day storage period. The preservative activity of brine and the anti-oxidant activity of pepper and garlic mixture were evident from lower Thiobarbituric acid (TBA) and peroxide values of treated samples relative to untreated samples. Results of sensory evaluation showed a general preference for spice-treated samples.

    Description: The seasonal variations in the physicochemical parameters were studied from January, 2007 to December 2007, in Kontagora Reservoir, Niger State, Nigeria. The physico- chemical parameters were determined bi-monthly , using the following methods , temperature using mercury thermometer in degree centigrade, transparency using Secchi-disc , Pye Unicam model 292 meter used for pH and electrical conductivity. Dissolved oxygen by modified Winklerazide method, water hardness and Phosphate- phosphorus by method of Lind (1979), total alkalinity by standard method described by Boyd(l979) , Nitrate- Nitrogen by Phenoldisulphonic acid method. The rainy season mean values for water temperature, depth, pH, Nitrate-Nitrogen, were significantly (P〈0.05) higher than those for the dry season. However, for transparency, conductivity, dissolved oxygen, hardness, alkalinity, phosphate-phosphorus and total dissolved solid, the dry season mean values were higher than the rainy season mean value. As in most other Africa inland water bodies, there was seasonality in the physicochemical parameters variables. The torrential rains of the dam environment, the characteristics trade winds of the dry season, effect of deforestation, fertilizer application, herbicides, insecticide and other chemical factors might have contributed to the fluctuations of some of the physicochemical parameters detennined in the Reservoir.

    Description: Drying of freshly caught fish to heat from sunlight is the simplest method of fish preservation in the arid regions of the tropics, where heat energy from sunlight is of considerable intensity, the Kainji Solar Tent Dryer was developed to improve the traditional drying methods Bagrus bajad was used in this study as a result of its dominance in the Jebba and Kainji Lake Basin. The fish were dried in the Kainji Solar Tent Dryer and open sun and dying was completed within 2-4 days. Results from organoleptic study show that dried fish products in the Kainji Solar Tent Dryer were light, whitish-yellow colour, while the sun dried fish was dark orange in colour. Solar dried fish had mean score of 8.2 for appearance while sun dried fish had 5.2, sun dried fish had 6.6 for texture while solar dried fish had 7.8. For odor and taste solar dried fish had mean score of 8.2 and 8.4 while sun dried fish had 4.6 and 0. Moisture content was 10.6 for solar dried fish compared to 22.26 for sun dried fish. Crude protein and fat were 62.3 and 16.25 for sun dried fish compared to 82.14 and 8.46 for solar dried fish. Solar dried fish had 43.3cfu/gm compared to 132 cfu/gm for sun dried fish in the microbiological load assessment. Organoleptic assessment of the final dried product showed that the solar-dried fish were of better fish quality than traditional sun-dried fish.

    Description: The principle of Evaporative Cooling System (ECS) was adopted to construct a Wooden Evaporative Coolant Structure (WECS) to prolong the freshness of Tilapia, Oreochromis niloticus. The keeping quality of the two structures was compared with fish kept at ambient using temperature, relative humidity, weight loss and organoleptic indices. Results showed that the Basket ESC and Wooden ECS recorded lower temperatures and higher relative humidity values as compared with the ambient. Tilapia stored at ambient condition recorded significantly higher weight loss (P〉0.05) than those kept in BECS and WECS. Results of sensory evaluation showed that there was a gradual reduction in the organoleptic quality of the fish stored in BECS and WECS. Quality of whole fish by panelist after 8 hours of storage showed that the two ECS models recorded significantly higher (P〈0.05) freshness scores than fish stored at ambient temperature. Fishmongers should adopt this technology (BECS and WECS) as a means of prolonging the freshness of Tilapia Oreochromis niloticus before they are sold to consumers.

    Description: Quality deterioration (microbial load) of smoked white catfish (Chrysichthys nigrodigitatus) from Ekeonunwa market Imo state Nigeria, was studied for six weeks. The experimental fish was divided into two batches. One batch of 18 fishes with average weight of 700g was resmoked weekly at 75oC. the second batch of 18 fishes weighing an average of 750g was left unresmoked. Weekly samples of both unresmoked and resmoked fish were taken from different regions (body flanks, gill and gut) and analyzed in the laboratory. Total plate counts (TPC) for the bacterial organisms in both resmoked and unresmoked samples (Table III) ranging between 1.56 105 and TNTC ( too numereous to count) exceeded the range of specified microbiological limits recommended for fish and fishery products by ICMSF (1986). Pathogenic organisms isolated included Escherichia coli, Staphylococcus aureus, Lysteria monocytogenes, Bacillus cereus, Aspergillus flavus, Penicillium varrucossum, Yeast and Mucor. Both unresmoked and resmoked fish specimens were contaminated with these spoilage microbes, but the microbial load of the resmoked samples were less than those of the unresmoked samples. Resmoking beneficially reduces microbial load of stored fish, increases the shelf/storage life, but can not totally eliminate pathogens. The presence of pathogens raises a public health concern.

    Description: The morphometric characters of Cynothrissa mento from three major Lagoons (Ologe, Badagry and Epe) in Lagos, Nigeria were compared to assess the possibility of this fish species from the three Lagoons belonging to the same sub-population. The length-weight relationships (LWR), and condition factors (CF) of the fish were also described as well as the physico-chemical parameters of the three water bodies. The study was conducted between May, 2009 and April, 2010 and monthly sampling of fish and water was done in each sampling site. Seven7 physico-chemical parameters were assessed and these are; temperature, pH, salinity, turbidity, dissolved oxygen, total alkalinity and total hardness. A total of 294 specimens (Ologe 60, Badagry 174 and Epe 60) of C. mento were collected from the landings of the local fisher folks from the sampling sites. Seven morphometric characters; total length (TL), standard length (SL), body depth (BD), head length (HL), head depth (HD), eye diameter (ED) and interorbital width (IW) were measured. There was no significant difference (p 〉 0.05) in all the physico-chemical parameters measured among the sampling sites except pH. Coefficient of difference revealed that the C. mento from the three lagoons are uniform in all the morphometric parameters examined, which means that the specimens from the three sampling sites do not belong to different sub-populations. The growth coefficient/slope (b) values obtained for the fish species from the sampling sites ranged from 2.27 - 2.53, and differed significantly (p 〈 0.05) from 3, which indicates that most of the fish species have negative algometric growth.

    Description: Bacteria flora predominates the skin of freshly caught fish, and will invade the tissue of the fish immediately after catch. Two preservative methods (cold smoking and freezing) were used to store eighteen specimens of Chrysichthys furcatus harvested from River Niger at Cable-point, Asaba. Two specimens were randomly selected every day from the cold smoked specimens and on weekly basis from the frozen specimens for physical, chemical and biological examination for bacteria causing spoilage. Five bacteria isolates: Salmonella spp, Vibrio cholera, Escherichia coli, Staphylococcus aureus and Proteus vulgaris, were identified. Physical observation of the cold smoked fish after 24 hours showed the production of gas, off-odor, off flavour and slime formation. The colony forming units (CFU) of bacteria isolated from the fish immediately after harvest was 116 x 109 cfu/g. It increased to 268 x 109 cfu/g after 4 days of preservation, and to 64 x 109 cfu/g after four weeks of preservation. The Chi square (X2) analysis revealed that there was a significant difference between the bacteria load of frozen and cold smoked specimens. Free fatty acid value immediately after harvest was 0.90 %. It increased to 2.24 % after four weeks in the freezer and 2.35 % after four days of cold smoked storage. The Total Volatile Nitrogen profile at harvest time was 15.3 mgN/100g. It increased to 35.2 mgN/100g after four days, (for the cold smoked specimens) and 26.3 mgN/100g (for the frozen specimens) after four weeks. The peroxide and hydrogen ion concentrations followed the same increasing trend. The study revealed that freezer preservation was better than the cold smoked one. This is because bacteria proliferation was reduced and or halted in the frozen specimens, whereas it encouraged rapid bacteria growth in the cold smoked fish. The production of total volatile nitrogen (TVN), free fatty acid (FFA), peroxide value (PV) and hydrogen ion concentration (pH) was higher in the cold smoked specimens than in frozen ones, hence the cold smoked specimen exhibited shorter shelf life than their frozen specimens.

    Description: The changes that occur on proximate composition of some common fish processing methods used in Nigeria were studied in order to determine the nutritional content of the processed products. Traditional (smoke drying and sun drying) and modern (electrical oven drying) methods of processing were used to process Pseudotholithus elongatus and the results were compared with the fresh sample to determine the changes that occur during processing. The results for the fresh sample of P. elongatus were 79.50%, 1.50%, 0.8% and 18.2% for moisture, ash, lipid and protein. For the processed products, the moisture content for smoke-dried, sun-dried, salt sun-dried and oven-dried fish were 27.00%, 21.83%, 19.50% and 20.17% . Oven dried had the highest protein content (69.87%) while salt sun-dried had the lowest (54.90%). Lipid content was highest in sun-dried (6.6%) and lowest in smoke-dried (4.6%). Correlation between smoke-dried and sun-dried were r2 = 0.99, smoke-dried and oven-dried were r2= 0.98 and smoke-dried and salt sun-dried were r2= 0.98. There was no correlation between the fresh and the processed P.elongatus. The present findings revealed that processing affect the nutritional composition of fish.

    Description: The effects of groundnut oil and sodium chloride as protectants against insect infestation of dried fish were investigated for a period of 13 weeks. The fish samples were divided into 3 groups, a group was soaked for 10mins in 30% sodium chloride solution (Brine), and the second group was dipped in groundnut oil after smoking while the third group served as control. The samples were kept in different containers in the laboratory at temperature of 28oC and 70% Relative humidity for 13 weeks. Results show that, the fish treated with 30% sodium chloride was effectively protected from insect and moulds compared to sample treated with groundnut oil. The odour and the texture were also more attractive to customers. However, fish treated with groundnut oil was attacked by insects at week 12th and 13th with 6 Maculatus, 4 Necrobia rufipes species and at few mould colonies. The control specimens however was attacked by insects from week 8th to 13th with numerous number of both Necrobia rufipes and Maculatus species as well as mould colonies showing as early as from the 6th week. The results proved that sodium chloride is more effective than groundnut oil for long period of storage.

    Description: Women are the majority of the third World population. They are considered subservient to their male counterpart, even in Europe and America where women have greater basic human right. This paper evaluates the various roles of women in Fisheries and fish processing. Statistics from the European Union shows that, of the various fishing sectors, participation of women (in terms of number) was greatest in fish processing, followed by marine aquaculture, marine fishing and inland aquaculture, with no women involved in inland fishing. In Asia and Africa women are basically involved in fish processing and marketing. In Asia (Thailand and Philippines), women are involved in hatchery operations in aquaculture in addition to fish processing. The finding of the review shows that Fish processing in developing countries, principally Africa is not attracting young literate generation who may have better management competence. It further revealed that, in Nigeria women are directly involved in capture fishery, in addition to fish marketing and processing. This is aimed at empowering women economically to meet the pressing needs of the family. The paper further assesses the problems of women in fisheries and fish processing namely, access to financial resources, education, support services and the need to ensure food security. Possible ways of improving women’s participation in fisheries were highlighted.

    Description: This paper emphasizes that efforts in the upgrading of the fish processing industry in Southeast Asia should be directed at each country s traditional fish products. In the coming era, the increase in food production may not match the world s population growth. In this respect, the major challenge for the fish processing industry is the utilization of all fish caught. Emphasis on development of new products might be one area of responsibility. However, this paper stresses the importance of traditional fish products of each country because these products have survived many decades without any assistance from government or perhaps even society. In other words, there must be some reason for their existence. When fish technologists are able to help the traditional fish products industry, the industry will play a more powerful role in the future. This paper focuses on a simple and fast way of boosting the fish processing industry in the region by emphasizing on the upgrading of existing traditional fish products.

    Description: 1. Internationalization and Diversification of Surimi IndustryIt is estimated that the world s surimi production in 1994 was 512,000 tonnes. Japan was the biggest surimi producer in the middle of 80 s, but the surimi production of Japan decreased to 132,000 tonnes in 1994. The USA started the commercial production of frozen surimi in Alaska in 1985 and became the biggest surimi producer in the world with 209,000 tonnes in 1994. Thailand started surimi production in 1978 and has increased its production to 65,000 tonnes in 1994. The success of the Thai surimi industry stimulated development of surimi production in other countries in the region. With an increase in the number of countries producing surimi, the fish species used for frozen surimi has been diversified. Of about 500,000 tonnes of frozen surimi in the world, the share of Alaska pollock surimi was 60% in 1994. The share of surimi from other fish such as whiting, threadfin bream, etc., has been increasing over the years.2. Intrinsic Quality of Frozen SurimiStability of the meat proteins (especially of myofibrillar proteins) against heat and frozen storage is species dependent. Protein stability of cold water species is much poorer than of temperate/tropical water species. The stability or the rate of denaturation of myofibrillar proteins is closely related to the temperature of the water in which the fish lives. Strict temperature control is required for surimi of Alaska pollock and other cold water species.3. Internationalization of Surimi-Based ProductsThe world production of surimi-based products in 1993 was estimated at 1,090,000 tonnes. The biggest kamaboko producer is Japan, followed by Korea, USA, Taiwan and Thailand. The production of imitation crab and seafood analogs began in the middle of the 70 s and are now manufactured throughout the world.4. Recent Trend of Kamaboko Products in JapanJapanese consumers now prefer softer textured foods than previously and pay more attention to healthy foods. Some of the successful soft textured products are made by incorporating isolated soy protein into surimi-based products.5. New Surimi-Based Product TechnologyVacuum grinding mixers have been introduced more and more into kamaboko processing plants in Japan. Imitation crab meat, scallop or squid with fine texture and juiciness as compared to conventional products are now produced by twin-screw extrusion cooking. Ohmic cooking, or Joule cooking, with heat generated by flowing electric current through the foods is becoming popular in the kamaboko industry. Proteinase inhibitors such as blood plasma are used for Pacific whiting surimi infected by Myxosporidian parasites.

    Description: The HACCP philosophy is gaining momentum with industry and regulators alike as the best approach to assuring the highest degree of food safety. This is exemplified by the numerous publications and courses on this subject in recent years as well as examples of successful application by industry and the efforts of committees such as the NACMCF. The HACCP philosophy is also gaining worldwide acceptance, as shown by the recent activities of the Codex Alimentarius Commission s Food Hygiene Committee. HACCP is a common-sense philosophy that can be applied to food systems ranging from the simple to the complex. Applying the principles as described in this paper demonstrates that the process, while requiring careful thought, is not unattainable. Joining HACCP with another related management philosophy which is growing in popularity - Total Quality Management (TQM) - can provide a formidable combination for competitive advantage.

    Description: Fish and fishery products are important sources of food and are economically important to Thailand. Though marine fisheries production has become stagnant in the past decade, output is supplemented by both fresh water and coastal aquaculture production. Total fisheries production in 1993 was reported to be 3.4 million tonnes, of which aquaculture fisheries accounted for 9.7 %. The consumption of fishery products especially seafood is probably a result of the country s high economic performance. The upturn in fish processing industries and the Department of Fisheries HACCP-based inspection program were recognized in the region and internationally in the past five years. Consequently, Thailand has become, by value, the largest fish exporting country in 1993 and 1994. Processing technology is being developed to meet market demands for quality, safety and wholesomeness. Preservation technology for dried and fermented products is upgraded utilizing modem equipment and technology to extend shelf life and to improve standard for wholesomeness. While technology involving value-added products are developed locally for industrial scale production, processing technology is also being developed for dried, chilled, frozen, canned, retort-pouched and comminuted products. Quality management becomes the most concern of the fish processing industry. The Hazard Analysis and Critical Control Point (HACCP) based inspection system was enforced as mandatory for fish exporting companies in January 1996. Inspection techniques, monitoring and verification procedures are developed to strengthen the implementation of HACCP quality assurance program by the industries. Fish inspection for quality assurance has been focused on meeting with international standards. New inspection laboratories and scheme for raw material control were established to employ the latest techniques to assure quality and safety of products and raw materials to be used for processing. The Government has put strong emphasis on quality management program for the industry. In the 8th National Economic and Development plan (1997 - 2001), the Department of Fisheries will continue projects to accelerate the development of quality products and quality system, to maintain the supply of safe and quality fishery products to local and international market and to resolve problems faced by the industry.

    Description: Fish remains an important source of protein for the Malaysian people regardless of their economic status and background. This commodity is an important export earner as well as providing employment to the nation. A substantial percentage of the total marine fish landing and aquaculture produce is processed into various products, namely reduction products, dried and/or salted fish, fish snacks, fermented products, surimi and surimi-based products, frozen and smoked products. About 7,000 tonnes of fish snacks are produced annually by small-scale processors throughout the country. These comprise mainly of intermediate products and puffed crackers from fish, prawns and cuttlefish and ready-to-eat fish satay, a spiced snack made mainly from yellow goatfish. Some of the problems relating to quality that resulted from improper control of processes are discussed. This paper outlines and discusses the critical control points in the production of fish crackers namely freshness of raw material, mixing, forming, cooking and the drying processes. This paper also emphasizes on the use of simple machinery and processes that can greatly improve the quality of fish crackers for better acceptance by its consumers. These include the use of deboning machines for more efficient flesh recovery, use of the stuffer for better forming of the dough, the use of mechanical/solar driers for better control of temperature and air flow during the drying process and proposes the use of suitable packaging materials to extend the shelf life of the product.

    Description: The proximate composition of the fresh water shrimp Atya gabonensis (Irvine), preserved by smoking, salting and sun - drying was determined and compared to the fresh shrimp. All the preservation methods significantly (p〈 0.05) increased the total dry matter (38.34 93%), protein content (17.31 48.9) and ash content (28.36 36.17%) over the fresh shrimp value. Moisture and lipid contents however, were reduced from the fresh shrimp's 61.66% and 25.29% to low value of 7.00% and 5.10% respectively. The preserved shrimp is, therefore, nutritionally superior to the fresh shrimp as preservation enhances its proximate composition. Of all the preservation methods used in this work, smoking is the best. It recorded the best preservation indices of lowest moisture content, higher dry matter, higher protein content and highest ash content.

    Description: Initial investigations into the use of Sardinella gibbosa for making surimi showed that gel strength (G.S.) of around 400 g cm was achievable under normal surimi processing conditions. Adjusting the pH during the leaching process, by means of NaHCO3 and by means of Na4O7P2 with vacuum, did not improve the G.S. The fat content of local sardine was low and did not interfere with the surimi processing. The optimum conditions for setting the gel of paste were subjected to between 40 to 50° C for 20 min, followed by 20 min at 90°C. The surimi underwent modori* when subjected to 60°C for 20 min. Sugar was necessary as a cryoprotective agent for frozen surimi. It was found that crude aqueous extract of unfrozen S. gibbosa kidney tissues had G.S. enhancing effect. Kidney extract made from frozen sardine which were then frozen again, lost this G.S. enhancing effect. Kidney extract made from unfrozen Caesio erythrogaster also had this G.S. enhancing effect. The kidney extract was heat stable, and retained the G.S. enhancing effect after exposure to 80°C for 10 min. However, the kidney extract did not prevent modori when the gel was exposed to 60°C for 20 min.

    Description: Threadfin bream (Nemipterus spp.) were bought from the landing pier and used as raw materials for frozen surimi production. The fishes were frozen at -36°C until the center of the fish was cooled to -18"C. The frozen fish were kept at -18±1°C for 0, 20, 40 days, then the fish were taken and processed to surimi. The frozen surimi were kept at -18±1°C for 0, 1½ and 3 months. The results showed that surimi made from 40 days cold-stored fish have more yellowness in colour than the zero- day fish. Gel forming ability of surimi was affected by the storage time of both frozen fish and frozen surimi. Gel strength of kamaboko made from prolonged-storage surimi was lower than zero-month-stored surimi. However, the folding test still registered AA after prolonged storage of surimi made from frozen fish of 21 days to 3 months. It is recommended that frozen threadfin bream can be used for surimi processing; this surimi should be directly processed to fish jelly products as soon as possible in order to obtain good gel-forming ability. To improve the gel-forming ability of minced fish, ascorbic acid was added at 0.1 and 0.2% by weight during the mixing process. After production, surimi were kept frozen for 1½ months. It was found that 0.1% by weight of ascorbic acid improved the gel quality of frozen stored surimi. Increasing the amount of ascorbic acid to 0.2% resulted in lowering the pH of surimi. It also lowered the gel strength of prepared kamaboko.

    Description: Surimi from bighead carp was used in the production of crab analogue and squid balls. Crab analogue using sweet potato starch and crab flavour powder resulted in better flavour, odour, texture and general acceptability than those using potato starch. Squid balls were also produced from bighead carp surimi and compared with commercial squid balls. Sensory evaluation showed that the formulated squid balls were comparable with the commercial sample in terms of odour, texture and flavour. The commercial squid balls exhibited better colour and general acceptability than the formulated squid balls.

    Description: The first HACCP training course in Vietnam organized by FAO and INFOFISH took place in Ho Chi Minh City in May 1991 with the participation of the managers from both industry and government. Following the principle of training other trainers, other training courses (where all leading lecturers were Vietnamese) were organized all over the country. Under the Government Project KN 04-15 “Upgrading the Quality of Frozen Fish Products" five fish processing plants from all important fishing areas were selected for the Trial HACCP Implementation Program. The trial gave us reasons to conclude that instead of immediate implementation of HACCP or ISO 9000 programs, the best way is to choose GMPs as the first step to lead into the implementation of HACCP in Vietnam. This paper lists the main reasons, presents the working steps and the experiences gained from various plants GMP implementation. Attention is paid to the role that NAFIQACEN (National Fishery Inspection & Quality Assurance Center) played in the implementation of the HACCP-Based Quality Management Program in Vietnam. The present obstacles are pointed out and activities planned to achieve the strategic objectives of the fisheries sector in the coming period are described.

    Description: Striped catfish (Pangasius sutchi) is a fatty fish which possesses a specific non-palatable flavour. Processing of this species into value-added smoked product so as to improve flavour and odour was therefore studied. The appropriate conditions for brining and dry curing were studied using 15, 20 and 26% brine for 10, 20 and 30 min, and salt to fish ratios of 1:3, 1:5 and 1:7 for 20, 30 and 40 min, respectively. Sample with the highest acceptability scores (P=0.05) of each curing method was selected for further study on appropriate conditions of natural smoking using coconut hull. Smoking temperatures at 60, 70 and 80°C were studied for the smoking time of 2 and 3 hr at each temperature. The proper conditions were found to be brining with 26% brine for 10 min, then smoking at 60°C for 3 hr or dry salting with salt to fish ratio of 1:7 for 20 min and smoking at 60°C for 2 hr.
