Mangrove crabs weighed 66.43±9.78 g and carapace width 7.40±0.43 cm. The container used was crab box and placed in the pond. Treatments consisted of 4; i.e. the use of sailfin molly meal and spinach, treatments A (40 and 20), B (40 and 25), C (40 and 30) %, D (commercial feed); using a completely randomized design. Test parameters: weight growth (W), number of crabs molting (NM), survival (SR), feed conversion (FCR) and physico-chemical physico-chemical water conditions. Data were analyzed by variance and Duncan's further test. The treatments had a significant effect on W, SR and FCR but no significant effect on NM. Water physico-chemical i.e. salinity was not favorable for crab growth. The use of sailfin molly meal and spinach in feed was as good as commercial feed.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89411224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aquatic contamination is a result of waste product discharge and anthropogenic waste runoff. The environment has turned into a repository for chemical contaminants that seep into estuaries and other aquatic environments, immobilising the aquatic biota, including heavy metals. Heavy metals like chromium can be both helpful and destructive to living things. It is both highly carcinogenic and poisonous. Chemical contaminants are released into the water by numerous enterprises. Chromium is among the many contaminants present in these disposals. Because Channa punctatus is a readily available and popularly consumed freshwater fish, it was selected as the test species. The experiment was conducted over the course of 28 days in 4 distinct aquariums, 3 of which contained chromium at various concentrations (Group 2-LC 50 /5; 20 mg/l, Group 3-LC 50 /10; 10 mg/l, and Group 4-LC 50 /20; 5 mg/l), and one aquarium (Group 1) served as the control. With an increase in the concentration of the heavy metal, the exposed fish exhibited more irregular swimming and became sluggish. Moreover, chromosome damage induced by chromium exposure increased the production of micronuclei in the interphase cells and increased the toxicant concentration. The findings indicated that acute chromium toxicity has a significant negative impact on normal histology of brain, genotoxicity and normal behaviour, which may be harmful to the fish population and ultimately to humans who eat fish.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"488 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85584086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out for a 6 months period running from July to December 2022. The fish specimens used for the study was obtained through catch statistics at the three major landing sites of the study area. The sites were sampled twice monthly for fish species. Sampling was by: Direct observation of the Fish species and gears at the landing sites. Fish identifications as well as measurement of weight and number of fishermen were taken. The results showed that Gill net (Taru), Cast net (Birgi), Lift net (Akauji), Longline (Rincha) and Malian trap (Gura/Malia) are the most preferred fishing gears used by fishermen in Upper Benue River Basin at Mayo Ranewo; the results further revealed number of fishers in the 6 months study period ranged between 13 to 22 while the efforts (fishing hours) ranged from between 17 to 29 hrs/day. The average weight of fish caught per fisher per day ranged between 16 to 26 kg. September and October have the highest Catch Per Unit effort range of between 19.36 and 20.30 kg/hr while the lowest catch per unit effort is recorded in August with range of between 11.28 to 12.78 kg/hr. These findings have important implications for the management of River Taraba fishery, and can be used to inform policies and regulations to ensure the sustainability of the fishery. Therefore, this study recommends that fishers are encouraged to adopt more sustainable fishing practices, such as avoiding sensitive areas or using less harmful gear.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90714266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal was to assess their effects on fertilization and hatching rates through the stripping method. Brood fish were administered Gonopro-FH and Ovaprim to stimulate ovulation, and the impact on fertilization and hatching rates was closely monitored. Ovaprim outperformed Gonopro-FH, showing higher fertilization (82%) and hatching rates (76%). The study also explored embryological development, revealing that Ovaprim resulted in fewer malformations in eggs, potentially leading to healthier offspring. Overall, Ovaprim proved more effective for inducing breeding in common carp through the stripping method, offering higher hatching and fertilization rates compared to Gonopro-FH.

Fish samples were examined, dissected and parasites were removed, identified and counted by employing standard techniques in parasitology. A total of 49 out of 258 collected fishes were infected with ten different parasites with an overall prevalence of 22.9%. The recovered parasites include four cestodes (30%), two digenetic trematode (23.23%), one monogenean, (1.01%), one acanthocephalan (8.08%), one secernetean (32.32%) and one nematode (5.05%). Generally, parasitic prevalence was not size dependent and the female fishes were observed to be more parasitized than male (p˃0.05). The mean intensity and abundance of parasites were higher in the stomach and intestine than the gills. Fish parasitism is one of the major problems facing fish production and could be sustained with high degree of pollution as indicated in this study. Hence pollution control and regular examination of the water bodies should be advocated to prevent low fish performance and production.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76973859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
