A feeding trial was conducted to determine the adequate level of dietary vitamin B₆ (pyridoxine, PN) for juvenile grass shrimp, Penaeus monodon. Purified basal diets were formulated using vitamin-free casein as the protein source. Graded levels (0, 10, 30, 60, 100, 150, 200 and 600 mg PN/kg diet)...

The potential of feed pea meal as an alternative protein source to soybean meal in practical diets for the juvenile tiger shrimp, Penaeus monodon, was assessed in several experiments. Six isonitrogenous diets were formulated to contain 40% protein. Protein from the feed pea meal replaced 0%, 20%,...

Effects of 3 ascorbate derivatives, namely, smallcap˜L-ascorbyl-2-sulfate (C2S), smallcap˜L-ascorbyl-2-monophosphate-Mg (C2MP-Mg) and smallcap˜L-ascorbyl-2-polyphosphate (C2PP) on tissue (hepatopancreas and muscle) Cu, Fe and Zn concentration in juvenile grass shrimp, P. monodon, were studied. The...

This paper reviews the different feeding strategies currently employed within semi-intensive farming systems for warm-water fish species in the tropics, including on-farm preparation techniques and management practices. Particular emphasis is placed on the important role played by natural food...

Seven semi-purified diets (35% CP and ME 3400 kcal/kg) containing defatted, freeze-dried shrimp meal, 1.0% soyabean lecithin and 0.5% cholesterol were supplemented with 6.5% stearic acid, coconut, safflower, maize, soyabean, linseed or menhaden fish oils and fed to P. vannamei (mean weight...

This proceedings consists of abstracts presented during the 10th International Symposium on Nutrition and Feeding in Fish (Feeding for Quality), organized by the National Centre for Marine Research, Athens, Greece and International Union of Nutritional Sciences Committee on the Nutrition and...

Shrimp diets with and without the antioxidant, butylated hydroxytoluene (BHT), were stored at 10°, 20°, 28°-30° or 40°C for 10 weeks. To monitor lipolysis and lipid oxidation, free fatty acid (FFA) content, peroxide values (PV), and malonaldehyde (MAL) levels were measured from the extracted lipids ...

This special issue contains 33 articles on fish nutrition and feeding strategies. Topics discussed are: micronutrients and health, broodstock and larval nutrition, nutrient requirements, metabolism and growth, and feed ingredients. Tables, illustrations, graphs and photographs are presented in some ...

Anthropogenic disturbance of farmed animals can be detrimental by adversely affecting behaviours and metabolic rate, potentially reducing their commercial value. However, relatively little is known about the normal behavioural time budgets and associated metabolism of many such species,...
