    Description: The acquisition or loss of Clinostomum tilapiae parasites by Oreochromis niloticus was studied. Four groups of 25 healthy fishes were stocked in the upper part of serial experimental ponds, while another four groups of 25 infected fishes were also stocked at the rear part of the serial experimental ponds. All the groups were fed at 3% body weight with the same compounded fish feed. Acquisition or loss of parasites and growth was monitored for a period of six months. The mean relative growth rate was 11.04kg/month for the healthy fishes and 5.62g/month for the infected fishes. The mean specific growth rate was 38.75% and 31.25% for the healthy and infected groups respectively. However the results were not statistically significant (p 〉 0.05). The parasite did not multiply on the host body rather the infection rate reduced from 100% to between 44 and 78%, parasite burden was reduced from an average of 3 per fish to 2.25 while the healthy fish acquired the parasite and the average burden was 2.15. The mean values of the prevailing water quality parameters were within the optimum range acceptable in fish culture systems in the tropics.

    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: Sustainable development in Tatabu fishing community can hardly be attained without a systematic socio-economic consideration of the productive activities and development needs of the people. Generally two important factors play a great role in rural livelihoods; the prevailing structures and processes and access to assets, which can be combined in a various ways to generate positive outcomes. In essence poverty and the opportunity to escape from it depends on all the above. The assets comprise of human, natural, social, physical and financial. The present study (emperically analyzed their strength, linkages and the effects of policy and structures on them, particularly as it translates to the socio-economic well-being of the fishers.

    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: Composition and abundance of macro-invertebrates, in Akwa Ibom State College of Agriculture, Fish Farm in UrukAnam Local Government Area, Nigeria, was studied from (December 2005 to May, 2006). Collections of samples were made with benthic net at weekly intervals. Stocked and unstocked ponds were selected for the study. The stocked ponds had 122 individuals macro invertebrates while unstocked pond had 160 number of individuals. The two ponds were dominated by Diptera followed by Coleoptera with single individual species. Groups which are regarded as clean water fauna were absent in both ponds. Generally, the ponds were poor in terms of number of taxa and individuals.

    Description: The length - weight relationship and condition factor of Citharinus citharus citharus was studied for a period of twelve (12) months from Lake Kainji, Nigeria. Nine hundred and eighty nine (989) fish samples (Citharinus citharus citharus) with total length ranging from 100mm to 530mm and weight ranging from 31.00g to 2250.00g were analysed. The results showed that the values of a, b and r were 0.0039, 3.2134 and 0.8997 respectively. The condition factor(K) values varied from 2.9 to 4.5, which means that the growth pattern of the fish is based on the value of 'a'. the fish species are also living well in the Lake as the 'K' are greater than one.

    Description: Studies on the food and feeding habit of T. fuscatus var fuscatus from the mangrove swamps of the Bonny River, Niger Delta revealed that the species is a deposit feeder but fed more on algae and protozoa. The variation of food types with season were determined from the numerical and frequency of occurrence methods of food analysis. The algae were of Stephanodiscus, Cosanodiscus. Navicula and Nitzschia species, while the protozoa were Arecella arenaria, Pseudodileptus and Trinema species. Feeding actively occurred at low tides, this coincided with the presence of algae on the mud surface. No qualitative seasonal variation occurred as T. fuscatus var fuscatus fed basically on the primary diets at all seasons.

    Impact of oil exploration on fisherfolks' livelihood and safety of fisheries industry in Nigeria (2021)

    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.
