Dietary P regulates phosphate transporter expression, phosphatase activity, and effluent P partitioning in trout culture
(Springer Verlag, 2003)
Phosphate utilization by fish is an important issue because of its critical roles in fish growth and aquatic environmental pollution. High dietary phosphorus (P) levels typically decrease the efficiency of P utilization, ...
Phosphorus utilization in rainbow trout (Oncorhynchus mykiss) fed practical diets and its consequences on effluent phosphorus levels
(Elsevier, 2003)
Excessive dietary phosphorous (P) concentrations in effluents from aquaculture present a major environmental problem. We therefore studied the effect of dietary P and vitamin D<sub>3</sub> on P utilization by rainbow ...
Effect of dietary phosphorus and vitamin D3 on phosphorus levels in effluent from the experimental culture of rainbow trout (Oncorhynchus mykiss)
(Elsevier, 2001)
Excessive phosphorus (P) levels in aquaculture effluents violate federally mandated limits and pose a serious threat to the freshwater environment. In rainbow trout culture, effluent P probably originates as fecal and ...
Sulphur amino acid requirement of juvenile Asian sea bass Lates calcarifer
(John Wiley and Sons, 1999)
The dietary requirement of juvenile Asian sea bass Lates calcarifer for total sulphur amino acids was studied. Fish (average initial weight of 2.59 plus or minus 0.08 g) were reared in twelve 500 L fibreglass tanks provided ...
Utilization of feed pea, Pisum sativum, meal as protein source in practical diets for juvenile shrimp, Penaeus monodon
(Elsevier, 2003)
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 ...
Midgut gland as monitor organ for the nutritional value of diets in Penaeus monodon (Decapoda)
(Elsevier, 1985)
Midgut gland cells of Penaeus monodon postlarvae were investigated by electron microscopy after starvation and refeeding with different diets.
Well nourished postlarvae could be starved for 5 days without irreversible ...
Requirements of juvenile milkfish (Chanos chanos Forsskal) for essential amino acids
(American Society for Nutrition, 1993)
The dietary requirements of juvenile milkfish (Chanos chanos Forsskal) for essential amino acids were determined in a series of experiments. The fish (< or = 8.0 g) were reared in fiber glass tanks provided with flow-through ...
Possible application of mibolerone for induced sex inversion of grouper Epinephelus coioides
(Japanese Society of Fisheries Science, 2001)
Thirty immature juvenile grouper Epinephelus coioides (19-168 g bodyweight, BW) were randomly stocked in four units 6 t tanks to determine if mibolerone can be used to induce sex inversion in groupers. After acclimatization ...
Gum arabic, carrageenan of various types and sago palm starch as binders in prawn diets
(Fisheries Research Society of the Philippines, 1982)
Sago palm starch, gum arabic and three types of carrageenan (EPT-2, St-0008-29 & St-008-30A) were tried as binders in a practical diet. EPT-2 carrageenan gave consistently better water stability than the other binders in ...
Supplemental feeding of Penaeus monodon juveniles with diets containing various levels of defatted soybean meal
(Elsevier, 1990)
Varying levels of defattedsoybeanmeal DSM (15, 25, 35, 45 and 55%) in supplementaldiets with approximately 40% crude protein and 10% crude fat were fed to tiger prawn juveniles in 1 m×1 m×1 m net cages set on the bottom ...
