    Description: The importance of information in every sector cannot be over-emphasized. The ability to identify and utilize our natural endowment depends on the availability of information resources within or at the right time. The low level of information provision in Nigeria is attributed to infrastructure as a result of inadequate funding of the sector. Research has shown that information has revolutionized the society, moving the world from the industrial age to the information age and completely changing the way the economy functions. Success goes with the best information. However, for now, if there must be increase in fish production and eco-tourism participation, employment opportunities, poverty reduction, food security and nature appreciation in terms of environment and living creatures, our fisheries scientists and policy makers will have to rely on sources of information using the advantage of libraries, and Information Communication Technology (lCT). This development in information resources affects many areas of Nigerian economy including the fisheries and eco-tourism sectors. The contribution of information resource in the development of the fisheries sub-sector can be viewed under those of fisheries information products like the Nigerian Fisheries and Aquatic Sciences. (NIFFIC) database, Proceedings of national conferences of Fisheries Society of Nigeria (FISON), annual and technical reports Fisheries Research Institutes in Nigeria. Also to be brought under perspective is the information products of eco-tourist institutions like the Nigerian National Parks.

    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: Fresh tilapia (Oreochromis niloticus) was smoked using two different kilns to evaluate and compare the microbial changes or quality, physicochemical and organoleptic characteristics. Smoked samples were dominated by Gram-positive bacterial, flora, Bacillus, Streptococcus and Staphylococcus. Fungi isolated included Aspergillus spp, and Penicillium spp. The two kilns used in smoking are Modified Drum Kiln (MDK) and Mud kiln (MK). The MDK had a higher impact on the total viable count (TVC) and reduced the TVC of the fresh sample by 37.5% while the MK reduced it by 29.5%. In a similar trend the MDK reduced the number of Staphylococci and fungi by 43.3% and 33.8% respectively while the MK only reduces them by 30.9% and 26.3% respectively. Statistical test indicated significant difference (P〈0.05) in the microbial load of fish processed in the two kilns. However, the reduction of the Coliform by the two smoking kilns is not significantly different.

    Description: Lagos state has a major sea port for landing of frozen fish from Mauritania, Senegal, the Scottish waters and other European countries. In the last three years, the dense population of the state has encouraged all kinds of trade to thrive. Fish as a major food in many Nigerian diets has been known to complement the high carbohydrate intake of majority of the Nigerian populace because of the unaffordable prices of beef in the market. The market for frozen fish is rich in Lagos. It has provided many women fishmongers a livelihood for over a decade. They have been able to sustain their families and improve their social status over the years. This study reports the modus operandi of the trade. The study covered a period of three months. Fish sales were monitored in Epe, Oyingbo, Ijora and Alaba markets. The cooperation of the heads of markets (Iya Olojas) were requested at every market. It was ensured that observations and the interviews/questionnaires do not interfere with the women's activities. Specific areas focused upon in the study included countries of fish imports, most acceptable species, packaging, purchase price, sales price and profit margins. Other important factors in the fish market that were studied included entrance into the fish marketing business, sources of finance and problems. The study also made suggestions on how to improve upon the fish marketing business of women in Lagos State.

    Description: There have been many outcries in the Nigerian media on the various environmental degradation of the vast water space in the Niger Delta area of Nigeria by oil explorers. About 70% of the Nigerian populace lives in the coastal areas where the occupation is predominantly fishing and farming. For most of the publications, the extents of impact on the fishing industry are not addressed in order for solutions to be given. Production from the fisheries sector has dropped astronomically thereby earning the country a deficit due to importation of frozen fish to the country. In this study, a survey of three states (Bayelsa, Rivers and Delta) in the Niger Delta area of Nigeria was done. The communities studied include Ogulagha, Okobelema and Okpoama. Personal interviews with fishermen and primary data on the sector’s contribution to fish production and GDP were also carried out. The study aimed at finding out the sources and nature of degradation and the impacts such have on the fishing industry and the socio-economics of the fishermen. The study revealed that there are no significant difference in the negative impacts of environmental degradation caused by the activities of the oil companies on the socio-economics of the fishermen ((F2,27=0.59, P〉0.05)) The difference is not significant and the hypothesis is therefore accepted. The major impact on fishing was depletion in catches and low income earnings by fishermen with a resultant poor quality of living and livelihood. Oil spills, foreign vessels incursions and bunkering, vandalization of pipelines were identified sources of depletion in fish catches from the wild. The personal interviews and Focus Group Discussion (FGDs) showed that most heads of communities rely on the remuneration they get from the companies and refused to mobilize the fishermen for joint action against the oil companies. Mitigation measures usually carried out by the oil companies do not actually replenish the destroyed mangroves where breeding of fishes take place. The communities need the Government to institute high level surveillance of the high seas and monitor the activities of oil explorers as well as education of the communities on the effects of bunkering near shoreline.

    Relationship among Tilapia guineensis fingerlings abundance and water quality variations in a brackish water reservoir in Lagos (2021)
    Fisheries Society of Nigeria | Lagos (Nigeria)

    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: Information on sex composition of fish/shellfish species is important in determining reproductive potentials and estimating size structure of a given stock. Sustainable fisheries management options and policies usually rely on this aspect of the reproductive biology. In the present study, the sex ratios of three palaemonid shrimps, Macrobrachium macrobrachion, Macrobrachium vollenhovenii and Macrobrachium equidens were studied over an annual cycle with respect to gear type. Male: female relationship for M. macrobrachion caught with beach seine, pushnet and trap were 1:2.2, 1:2.1 and 1:2.15 respectively, while the M:F ratios for M. vollenhovenii were 1:1.27 (beach seine), 1:1.32 (pushnet) and 1:1.64 (trap). The overall M:F ratios during the annual cycle were 1:2.15 (M. macrobrachion), 1:1.47 (M. vollenhovenii), and 1:1.74 (M. equidens). The monthly sex ratios indicated that there were more females than males during the period, except for M. equidens which had a ratio of 1:0.78 in the month of August. This is advantageous for the stock dynamics of the species, especially if the males could mate with more than one female during any reproductive season.
