Defining essential fatty acid deficiency in juvenile barramundi Lates calcarifer
Barramundi (Lates calcarifer), a catadromous teleost of significant and growing commercial importance, are reported to have limited fatty acid bioconversion capability, typical of marine species, and therefore require preformed long-chain polyunsaturated fatty acids (LC-PUFA) as dietary essential fatty acid (EFA). In this study, the response of juvenile barramundi (47.0 g/fish initial weight) f...
متن کاملDietary alpha-linolenic acid does not enhance accumulation of omega-3 long-chain polyunsaturated fatty acids in barramundi (Lates calcarifer).
This study examined the effects of substituting fish oil and fish meal with a blend of alpha-linolenic acid (ALA, 18:3 n-3) rich vegetable oils (14%, w/w) and defatted poultry meal (34%, w/w) in a formulated diet, on growth and tissue fatty acid profiles in barramundi fingerlings. Results indicated that on average, while the ALA levels of the barramundi liver and fillet increased with increasin...
متن کاملAcute and postexposure effects of ammonia toxicity on juvenile barramundi (Lates calcarifer [Bloch]).
Lethal and sublethal effects of ammonia toxicity to juvenile barramundi (Lates calcarifer) were investigated under laboratory conditions following the OECD guidelines for testing of chemicals. Acute toxicity was tested in a static nonrenewal system at pH 9.0 and temperature around 29 degrees C. The 24-, 48-, and 96-h LC(50) values for barramundi were 3.89, 3.67, and 3.31 mg total ammonia N L(-1...
متن کاملEffects of different feed restriction periods on the growth and fatty acid compositions in juvenile rainbow trout (Oncorhynchus mykiss)
The aim of this study was to determine the effect of different feed restriction periods on the growth performance as well as the biochemical and fatty acid compositions of fillet in rainbow trout (Oncorhynchus mykiss). Fish with an average initial weight of 64.80±7.41g were used in the study. The trial lasted 60 days and 4 different feeding diets were alternately applied to the fish. The contro...
