    Description: A static bioassay method to determine the acute toxicity of the herbicide propanil to Oreochromis niloticus was investigated under Laboratory conditions for 96 hours exposure period. Concentrations of propanil used include: 0.0096ml/l, 0.0103ml/l, 0.011ml/l and 0.012ml/l respectively. The lethal concentration (LC50) value of propanil on fingerlings of Oreochromis niloticus was 0.0097ml/l for 96 hours of exposure. The regression equation for probit kill from propanil was found to be Y = 29.84 + 12.33* log conc. (r2 0.9951, Y = Probit kill). Fish showed various abnormal behaviours upon exposure to propanil. Immediate reaction was erratic swimming and tendency to jump out of the test bowl. Others include: restlessness, un-coordinated movement, vertical swimming, air gulping, equilibrium loss, a period of quiescence and eventually death.

    Micro-credit: financing fish production in Nigeria - a review (2021)

    Description: Microfinance refers to loans, savings, insurance, transfer services and other financial products targeted at low-income people. Artisanal fishing is a crucial source of livelihoods in developing nations, particularly for low-income families in rural areas where job options are limited. Nigeria depends heavily on revenues from natural resources, especially oil hence income from fishing is particularly important to Nigeria. Aquaculture is also being practiced with a growth rate that has increased over the years. Sources of funding for the operators of these sectors of the economy who are mostly poor peasants will ensure sustainable production and income generation. Informal microfinance groups have existed before the advent of formal microfinance. Microfinance institutions in Nigeria operate in an environment that is dominated by commercial banks. However, their high deposit rate makes them attractive to the low income group. This paper examines the emergence of microfinance institutions, their contributions to fisheries and aquaculture and constraints to be overcome to enable them serve the fisheries and aquaculture sector better.

    Length-weight relationship and condition factor of two Hydrocynus species in Lake Kainji, Nigeria (2021)
    Fisheries Society of Nigeria | Lagos (Nigeria)
    In:  http://aquaticcommons.org/id/eprint/23520 | 19325 | 2018-05-08 15:51:20 | 23520 | Fisheries Society of Nigeria

    Description: In the study and understanding of fish biology, characterization and morphology, the length-weight relationship is of great importance. The genus Hydrocynus, is of high economic importance to the fisheries of Lake Kainji. This study investigated their length-weight relationship to establish the growth pattern of species within this genus. The ‘b’ values of the length-weight relationship for these species are less than 3. There was negative allometric growth (b〈3) for all samples of the Hydrocynus species. The correlation coefficients (r) are 0.9713 and 0.9888, for Hydrocynus forskali and H.brevis respectively. Condition factors ranged from 1.313 for H. forskali to 1.431 for H. brevis.

    Microbial load on the African catfish (Clarias gariepinus) sold in Markurdi metropolis: a case study of selected markets (2021)

    Description: The work was carried out using 48 samples of smoke-dried African catfish (Clarias gariepinus). Twelve samples each were obtained from high level market, Wadata market, Wurukum Market and North bank market respectively. Different media (SDA, MSA, EMBA, N.A, MCA), gram reaction and biochemical tests were carried out to confirm the presence of the pathogenic bacteria. There was a strong correlation between the bacterial count and water activity of the fish for all bacterial isolates. The micro-organisms isolated were Aspergilus niger, Mucor spp, Salmonella spp, Escherichia coli and Staphylococcus aureus which were indications of contamination from surrounding environment.

    Description: The shrimps were collected from three sampling sites: on the River Benue at Makurdi, Benue state, on the River Niger at Jebba and Lokoja and Idah at Kogi state from January to April, 2011. Macrobrachium felicinum and Atya gabonensis were sampled during this period, with Atya gabonensis occurring more abundantly. Condition factors of freshwater shrimps Atya gabonensis from the two water bodies in Nigeria range from 1.875for species in Jebba in March to 3.330 for Lokoja in March. The parameter ”b” of the length - weight relationship of the fresh water shrimps are less than three (rangingfrom 1.0233 for species from Lokoja in April to 2.7717 for species from Makurdi in Feburary). These values suggest negative allometric growth. The length frequency of freshwater shrimps sampled shows that peak populations of length groups occurred in April for species from Jebba and Makurdi while peaks occurred in January for species from Lokoja.Peak frequencies were observed in length of 4.0 - 5. 4cm and 8.5 - 9.9cm in January as well as 5.5 -6.9cm for species from Lokoja and in the group of 5.5 - 6.9cm in April for species from Makurdi and 7.0-8.4cm in April for both Makurdi and Jebba.
