    Description: A study was conducted in Abeokuta, the Ogun State capital with the objective to investigate if fish trading could be a tool of poverty alleviation and socio-economic enhancement of the status of women in the household. A total of 120 correctly completed, structured and pre-tested questionnaires, out of the 150 administered to respondents, were retrieved for data analyses. Demographic data of the traders showed that all the respondents were women whose ages ranged from 15 to above 45 years. The ages of 33-45 years constituted 33.3% of the respondents while the age bracket of between 27-32 years constituted 23.3%. Majority (73.3%) were married while 25% were single-headed households (divorced or widowed). The study revealed that most of the respondents (approximately 61%) were able to meet their family expenditure jointly with their spouses while 28.3% of the respondents met the financial responsibilities of their families solely from the profit. Access to credit was found to be a major limitation. The study further revealed that 86.7% of the respondents would like to continue with the business because they were satisfied with the profit accruable to them from the trade.

    Description: Proximate composition and sensory evaluation of Africa catfish Clarias gariepinus harvested from earthen ponds, reservoir system, tank flow - through system and Flow Rivers were determined. Chemical assessment was based on the method of analysis of the Association of Official Analysis (AOAC). The samples collected shows moisture content 71.71~c1.65%, 74.20~c1.39, 73.60~c2.3% and 72.29~c68% from earthen ponds, reservoirs, and tank flow- through system and rivers respectively. The crude protein 9.77~c2.66%, 20.99~c0.68, 19.80~c0.53% and 18.84~c1.00% from earthen ponds, reservoir system, tank flow- through system and rivers respectively. There was no significant difference (p〉0.05) among the means recorded and the locations where the fish samples were collected has no effect on the value of the moisture and the crude protein content of the fish samples when compared. Crude fat contents 5. 68~c0. 81 %, 4.95~c0.38%, 3.85~c0.56% and 1.35~c0. 29%from reservoir system, low through system, earthen ponds, and rivers respectively. Ash content of the fish samples were 1.52~c0.40%, 1.49~c0.40%, 2.23~c0.91 % and 1.47~c0. 60% from earthen ponds, reservoir system, tank flow- through system and rivers respectively. There was a significant difference (p 〈0.05) among the means of the crude fat contents and ash contents. The location where the fish samples were collected influenced the means of the ash content and the crude fat contents. The taste, odour, appearance and texture were the indices for the evaluation. Fish from rivers were most preferred followed by earthen ponds, reservoirs system and tank flow- through system respectively.

    Description: Mechanization of agriculture to promote and improve the yields from agricultural practices has necessitated the use of pesticides and other agrochemicals. The effects of using these pesticides on the environment are rarely considered by farmers. This study investigated the effects and sub-lethal effect of atrazine on tilapia, an ubiquitous culturable fish species. The 96 hr LC50 was determined using static renewal bioassay method while the effect on haematological parameters was determined after exposure for 3 weeks to sub-lethal doses of atrasine. The LC50 was found to be 6.977mg/l. Sub-lethal exposure resulted in anaemia and increased the white blood cell counts.

    Fatty-acid composition of Macrobrachium vollenhovenii in Ogun estuary, Nigeria (2021)
    FISON | Lagos (Nigeria)
    In:  http://aquaticcommons.org/id/eprint/24200 | 19325 | 2018-05-16 15:22:08 | 24200 | Fisheries Society of Nigeria

    Description: A study was carried out on the fatty-acid composition of Macrobrachium vollenhovenii (African river prawn) in Ogun estuary, Ogun State, Nigeria. Sexes and size groups were considered during the study. Fatty-acid analysis was done in triplicates and data obtained were analyzed using descriptive statistics, analysis of variance and Duncan's multiple range tests. Fatty acids analysed which included oleic acid, linoleic acid,' stearic acid, myristic acid, palmitic acid and lauric acid were classified into saturated and monounsaturated fatty acids. All values of saturated fatty acids were higher in female (29.64%) than in male (25.50%) p〈 0.05. So also the monounsaturated fatty acid also showed higher value in female (29.64%) than in male (25.50%). All fatty- acid values were higher in female M. vollenhovenii than in male. Meanwhile, myristic acid was highest in the two sexes and the combined sexes, (35.68% female), (33.14% male) and (34.74% combined sexes). The fatty-acid components were not influenced by the size of the fish. This study clearly indicated that the nutritive value of M. vollenhovenii is quite well comparable to the edible species of decapods already studied (shrimps, prawns and lobsters) and could be included in both human and livestock diets.
