Brood Mussels was stocked at the rate of 80/decimal in three different captive conditions viz Treatment 1; High aquatic vegetation without any disturbance, Treatment-2; Light aquatic vegetation with disturbance and Treatment-3; No aquatic vegetation with disturbance for breeding. As the freshwater mussel needs host fish to fulfill its life cycle, different fish species were stocked at the rate of 150/decimal. Microscopic observation indicated the occurrence of higher glochidia in the gills and fin of Oreochromis niloticus , Puntius sarana and Heteropneustes fossilis during breeding season. After nine month of brood mussel culture juvenile mussels were harvested from the ponds. A total of 2425±122.01 juvenile mussels per decimal were collected from the treatment 1 followed by 750±55.97 and 370±46.70 juvenile mussels from treatment 2 and treatment 3 respectively.

Among the metals studied zinc (Zn) values were higher for both species while cadmium (Cd) values were lower. Ranking profile in organs was: liver >Gills > muscles with metal in order of Zn > Pb > Cu > Cd. Concentration of metals varied significantly ( p <0.05) in organs for T. dageti . Zinc (Zn) recorded higher concentration (1.2000 mg/kg) while cadmium recorded lower values (0.0034 mg/kg). Also the correlation results during the study for the two species showed C. gariepinus have a strong association with the heavy metals compare to T. dageti. The Correlation association of heavy metals for cadmium (Cd) showed there was significant difference ( p <0.05) for affinity for metal between the species. However, Lead (Pb) concentrations showed weak correlation between C. gariepinus and T. dageti during the study period. The correlation results also showed significant difference ( p <0.05) in zinc (Zn) concentrations for C. gariepinus compare to T. dageti . Results of this study ascertained occurrence of heavy metals in lower river Benue and that variations in levels affect fish. All metals studied were within safe range for fish and fisheries product by the Food and Agricultural Organization (FAO)/World Health Organization (WHO) in the two species. However continuous monitoring and check on fish species for heavy metals load should be encourage and sustained. Heavy metals concentrations should also be investigated in other commercial species of the river to assess their safety for consumption and routine studies of the river water should also be sustained.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84897027","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}

It is claimed that ingestion of Kulthi cures urolithiasis. Studies were therefore, planned to induce urolithiasis experimentally in cockerel to observe the effect of feeding Kulthi on growth, feed intake, feed efficiency and levels of serum calcium, phosphorus and magnesium.For the present study, 50 cockerels were divided into 5 groups of 10 each and fed 5 different diets viz. diet I- Control having Normal Calcium (1%) and Normal available Phosphorus (ap 0.5 %) - NCNP; II- High Calcium (3.25%) and Low available Phosphorus (0.3%) – HCLP (to induce urolithiasis); III- HCLP + 1% NaHCO3 (Sodium Bicarbonate) - HCLP (B); IV- HCLP (B) + 1% NH4Cl (Ammonium Chloride) – HCLP (A); V- HCLP + 1% NaHCO3 + Kulthi seeds – HCLP(B) K. Diets were fed from 9 to 32 weeks of age. During the experimental period, body weight, feed intake, feed efficiency was recorded. The levels of serum Ca, P & Mg were determined at monthly interval. X-ray and histopathological examination done at the end of the experiment. The results of study indicated that HCLP diet adversely affected growth, feed intake and feed efficiency. Incorporation of Kulthi in HCLP diets improved feed intake and gain in body weight. All the HCLP diets has no beneficial effect in preventing urolithiasis & kidney damage except HCLP diet with NH4Cl – beneficial in preventing urolithiasis. The mineral levels were at par in all the groups. During the last week of experiment, a metabolic trial for 3 days was conducted and the retention of minerals was studied. It was at par in all the groups.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135688564","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}
