    Description: This paper examines the importance of capacity building and training requirement for the benefit of fisheries and aquaculture extension in Nigeria. It involves the analysis of secondary data bothering on the management of agricultural extension in Nigeria over time vis-avis various agricultural development programmes in the past in which fisheries and aquaculture extension was apparently de-emphasized in favour of crop and livestock agriculture. It is therefore recommended as a way forward that a favorable reform in the Nigerian agricultural extension system will be a necessary avenue to put fisheries and aquaculture extension in proper perspective for effective service delivery which will be a good entry point to achieving the millennium development goals of combating hunger, extreme poverty and attainment of food security in Nigeria.

    Description: The study examined the contribution of women to fisheries in Kainji Lake Basin, Nigeria. The sample size of 80 respondents was selected through a purposive sampling in ten (10) fishing villages around Kainji Lake Basin. Instrument for data collection was semi- structured questionnaire. Data was analyzed using descriptive statistic. The result showed that the women are mostly engaged in processing, marketing and financing. About 60 percent of the women interviewed are engaged in marketing and financing. Ten (10) percent of the respondents are engaged in financing. The low participation in financing is attributed to high amount of capital involved. It is recommended that women should be made to benefit more from rural development policies and programmes.

    Description: The proximate composition and amino acids assay of smoked Clarias gariepinus and Oreochromis niloticus were determined using standard procedures. The mean proximate composition of Oreochromis niloticus are 8.9% moisture, 16.00% lipids, 5.6% ash, 44.5% crude protein, 0.42% crude fiber and 24.9% NFE while Clarias gariepinus has 8.19% moisture, 15.55% lipids, 4.725 ash, 40.46% crude protein, 0.50% crude fiber and 30.58% NFE. There is therefore a nutrient variation between the 2 species of fish Oreochromis niloticus has higher crude protein, lipids, moisture and ash content than Clarias gariepinus.The amino acids profile shows that both fishes have 17 amino acids. Apart from Tryptophan, the following essential amino acids Histidine, Methionine, Threonine, Isoleucine, Leucine, Lysine, Valine and Phenylalanine are present in both fish. Oreochromis niloticus however has higher quantities of the essential amino acids except for Histidine than Clarias gariepinus

    Description: The food and feeding habits of Protopterus annectens of the River Rima and Goronyo Dam in North Western Nigeria was studied. A total of one hundred and eighteen (118) fish samples were collected from October, 2001 to September, 2002 and the stomach contents were analyzed using frequency of occurrence method. The feeding adaptation with respect to mouth and related structures, gill rakers and dentition were examined. The gut length and fish length indicated rectilinear positive relationship. The regression coefficient (b) and correlation coefficient (r) of GL TL relationships were highly significant (p〈0. 01). The main taxa of food substances found in the stomachs included substances of plant and animal origins, with overall frequency of 49. 1and 38.3% for the samples from River Rima and 27.2 and 60.3% for those from Goronyo Dam in the same order. The results of percentage occurrence of the food items in the dry season showed that animal substances in the juveniles (51.7%) and the adults (41.4%) were higher than the plant materials in the samples from the two water bodies. In the rainy season, the percentage occurrences of animal substances were higher in the adults (= 30cm) samples from Goronyo Dam than those samples from River Rima, while the same food items were absent in the juveniles (= 30cm) from the two water bodies. These feeding adaptive features indicate the roles of the species in their ecological niche and provide base line information that could be useful in satisfying their food requirement under culture condition. The diversity of food substances found in the stomach and their occurrence in the juveniles and adults varied with the water bodies and season.

    An appraisal of the traditional fish handling and processing methods in Lake Chad (2021)
    FISON | Lagos, Nigeria
    In:  http://aquaticcommons.org/id/eprint/23218 | 19325 | 2018-03-18 13:40:29 | 23218 | Fisheries Society of Nigeria

    Description: The paper reviews the various techniques of fish handling and processing in Lake Chad. Poor handling of fish catches on board coupled with the distant location of the fishing grounds and thick aquatic vegetation on the lake which hamper fast movement of catches to the processing centers are the bane of good quality fresh fish getting to the processors. The techniques adopted in processing and preservation are mainly smoking, char-burning and sun drying. Defects suffered by the processed products of the methods include high moisture content, heavy insect infestation, bacterial decomposition and fungal attack. Protection of catches from direct sunlight by spreading wet jutes over them will lower the rate of deterioration. Removal of the aquatic vegetation by appropriate authorities and canalization will ease movement of fish catches to the processing centers. More serious enlightenment of the processors on the adoption of the 'Chorkor' oven will reduce the problems presently facing cured fish. The use of rambo insecticide and other dangerous chemicals by the fish processors and marketers for the preservation of fish products before repackaging should be discouraged.

    Description: A 7.0 meters Length Overall (LOA) flat bottom canoe similar to the one commonly used for fishing in Kainji lake, but with some modifications, was designed. The improvements/modifications over the local canoe include, an additional chine to reduce the flatness of the bottom which was absent in the local canoes commonly used. The canoe's light displacement (weight empty) was 0.48 Tonne, which was similar to local canoe of same size. The draft obtained was 0.13 M( 13cm), which is 36.9% of its depth (0.48 M). The capacity of the canoe was 1.304 tones. The water plane area (WPA) was 3.89 M2; WPA coefficient, and block coefficient were 0.83, and 0.82 respectively. The modification on the canoe resulted in provision of a canoe with the bottom shaped close to V-bottom to aid better performance on rough turbulent water such as the Kainji Lake, and increased life span of canoe and safety of fisher folk while aboard fishing.

    Description: The paper examines the prospect and constraints of fisheries extension under the unification policy. It revealed certain barriers influencing its fullest utilization as well as fisher folks participation in extension programmes. Some of the barriers identified are related to inaccessibility, logistic support, improper aquaculture methodology, insufficient applied research in small scale fisheries, inability to convert research findings into positive results by small scale fisheries, inadequate number of fisheries research personnel within the existing research centers and institutes catering for the fishers sector, complexity of issues, lack of coordination and continuity in research and data deficiencies in small scale fisheries. Based on the findings, the paper recommends that, the effectiveness of the methods of identifying research needs by practitioners be assessed, the impact of the generated research results in reducing or solving field problems be ascertained, the constraints to diffusion of proven technologies from research being integrated into small scale fisheries be evaluated, the degree of effectiveness of extension delivery tools on .fishers technology adoption be ascertained, and lastly, adequate applied research in small scale fishery be emphasized.

    Description: Comparative study on the microbial load and proximate composition of fresh lean fish Labeo cubie and fresh fatty fish Synodontis membranaceus with their smoked products were carried out. The colony count of different parts was carried out on all the samples and the results show the highest microbial load on the gut of both the fresh lean fish and the fresh fatty fish. The smoked dried lean fish and the smoked dry fatty fish had lower microbial counts compared to their fresh samples because smoking reduces the microbial load on fish. Biochemical characterization carried out on all isolates confirmed Gram-negative bacterial isolates. The proximate composition show that water is the most affected nutrient during the hot smoking of both the fresh fish sample and the fresh fatty sample with a corresponding increase in protein content. There was a significant difference (p〈 0.05) in proximate composition of smoked product of fresh fatty fish and the fresh lean fish. The colony counts of different parts of the fish reveals that majority of the microorganisms is found in the guts followed by gills and the lowest in the skin this is the pattern in the two fresh fish but for smoked fish the gut is usually removed before smoking.

    Description: Good handling of fish from the point of harvest to consumption is very essential and the quality of fish can only be maintained if only suitable containers are used in its processing, transportation, distribution and marketing. This study analyzed the different containers used by fishermen at lake Alau community in Konduga Local Government Area of Bomo State. The study was carried out in two prominent leading sites of lake Alau community which are kachalari and Abbari with the aid of questionnaires interview conducted with 50 randomly selected respondents fishermen. Both primary and secondary data were collected. The collected data were analyzed using the market cost of the various fish containers. The result shows that fish containers such as Metal basin, sacks, flat sacks and Metal trays have strong strength while Baskets, jerry cans and calabash have moderate strength the polythene bags, stationery and news print are very weak. Also baskets have the highest percentage of usage 20% while flat sacks, polythene bags and stationery have the highest percentage of 4%, which are the lowest. It can be concluded that, the different containers are afforded to fishermen but most of the containers are often kept dirty, which lead to poor hygiene, rough handling and invariably post-harvest losses and shortage in food supply. It can be recommended that, sheds should be provided at the landing sites to protect fresh fish the direct heat of the sun and enlightment of fishermen and traders on the minimum standard o fthe quality and hygiene for fish and fishery products.

    Description: Cephalic abnormality in nine mating groups involving Clarias gariepinus with cephalic abnormality, non Cephalic and Maiduguri origin were investigated to determine the level and the genetic basis of the occurrences and its aquaculture implication. The highest mean percentage survival in a Cephalic crossed with non cephalic group was 68.6% whereas the last mean percentage survival was 25.7% in the group of Maiduguri cross with Maiduguri parent. Cephalic abnormality was observed in the crosses with both female and male cephalic with a total frequency ranging from 0 % to 70.8. %. The least number of cephalic abnormality was 18.5% which involved a cross of non cephalic with cephalic, and the highest was 70.8%. This level of cephalic abnormality shows that the defect was hereditary. This result implies that, the genetic factor is a major contributor in the feature of cephalic abnormality in Clarias gariepinus.
