Studies on Mortality and Histopathological Alteration on the Gills of Oreochromis niloticus Juveniles Following Exposure to Ethanolic Extract of Phramenthera capitata under Laboratory Conditions
No full textThe study was conducted using two replicate (Batch A and B) for 96 hours under controlled laboratory conditions, with five different concentrations of the extract ranging from 0 to 40 mg/l. The results of the study revealed that the extract had a concentration-dependent toxic effect on the test organisms, with induced behavioural changes such as abnormal and uncoordinated swimming movement, restlessness, respiratory difficulties, and attempts at jumping out. The alterations of physico-chemical parameters of the test water were also observed, indicating the adverse effects of the extract on the aquatic environment. The 96 hours LC50 for Oreochromis niloticus was determine to be 22.124 mg/l representing a log-transformed concentration of 1.345 mg/l. This is the concentration where 50% of the test organisms is expected to die at the end of the 96 hours’ bioassay. The histopathological examination of the gills revealed pathological changes in the test organisms at concentrations of 20, 30, and 40 mg/l whereas no histomorphological changes was observed at 0 and 10 mg/l concentrations of the extract. The result of the present findings suggests that ethanolic extract of P. capitata had severe impacts on the test organisms resulting in mortality and gill damage

Effects of Dietary Vitamin E Supplementation on Growth Performance, Body Composition of Golden Trevally, Gnathanodon speciosus
No full textGolden trevally, Gnathanodon speciosus is a new candidate for aquaculture in Viet Nam. This species has rapid growth, high market value, delectable flavour. Finding solutions to enhance production by promoting growth is necessary in golden trevally aquaculture. Vitamin E is one of the feed supplements which has proven the benefit on other aquaculture species but there has not been any study on golden trevally. Therefore, this experiment was designed to test the effect of vitamin E on the golden trevally, Gnathanodon speciosus. Three levels of vitamin E (50, 100, and 200 mg kg-1 diet) were supplemented to the basal diet (control diet). There was 4 diet treatments and 3 replicates for each treatment. The golden trevally (initial weight 7.63 g ± 0.13 (SEM)) were fed experimental diets for eight weeks. The growth performance and protein and lipid content of tissues were evaluated. At the end of the feeding trial (week 8), the presence of vitamin E in a fish\u27s diet resulted in a significant increase in its growth rate (P < 0.05). The survival rate of fish fed diets containing 50 - 200 mg of vitamin E was substantially higher than that of control fish. In addition, protein and lipid levels in the flesh of golden trevally increased significantly as vitamin levels in their diets rose. For optimal growth and survival, it is recommended to supplement the diet of golden trevally with at least 50 mg of vitamin E per kilogramme. In conclusion, supplementing the diet with vitamin E improves growth, survival, and body composition in juveniles of this species. As this experiment is the first study on the effects of vitamin E on golden trevally, it is worthy of investigation
Effects of Growth Promoter-Enriched Farm-Made Feeds on the Growth, Flesh Quality and Economics of Labeo rohita Culture
No full textAims: The study compared the effects of three growth promoters enriched farm-made feeds with a commercial carp grower feed on growth, flesh compositions and palatability, and economics of Labeo rohita culture.
Study Design: The study was carried out through four treatments with three replications in each treatment. A commercial carp feed was used as control (T1, without growth promoter) and three experimental feeds were formulated by using locally available ingredients with the addition of three growth promoters viz., charger gel (CG), eon fish grower (EG) and aquazyme plus (AP) treated as T2, T3 and T4, respectively. Fifteen juveniles of L. rohita with initial weights ranging from 131.17±9.60g to 133.33±8.84g were stocked in each cage (96ft3) and served a daily ration of 5% body weight.
Place and Duration of Study: The study was conducted in 12 cages set in an experiment pond at the Department of Fisheries, University of Rajshahi, Bangladesh for 80 days (June-August, 2022).
Methodology: Growth and feed utilization parameters by means of weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR), and chemical composition viz., crude protein, lipid, carbohydrate, fiber, ash and moisture content of feed and fish flesh along with palatability indicators viz., odor, taste and texture were evaluated according to standard formulae, AOAC methods and organoleptic sensory technique, respectively.
Results: CG, EG, and AP enriched feed exhibited significantly better growth performance, feed efficiency, flesh composition and palatability indicators compared to the control feed. Additionally, CG enriched feed was the most economically efficient followed by EG and AP enriched feed in terms of feed cost/kg production.
Conclusion: The findings conclude that charger gel enriched farm-made feed is more economical and yields better growth and flesh quality of L. rohita than the selected commercial feed
