Development of digestive enzyme activity in larvae of spotted sand bass Paralabrax maculatofasciatus. 1. Biochemical analysis
TLDR
It is concluded that the enzymatic equipment of P. maculatofasciatus larvae is similar to that of other marine fish species, that it becomes complete between days 12 and 18 after hatching, and that it is totally efficient up to 25 dah. Expand
Effect of dietary protein level on growth and survival of juvenile freshwater crayfish Cherax quadricarinatus (Decapoda: Parastacidae)
TLDR
The results suggest that optimum protein level for 1-g juvenile C. quadricarinatus is 31% in least-cost diets, and the information obtained will contribute to the formulation of diets that will enhance production of the crayfish. Expand
Effects of dietary supplementation with probiotic live yeast Debaryomyces hansenii on the immune and antioxidant systems of leopard grouper Mycteroperca rosacea infected with Aeromonas hydrophila
TLDR
Yeast (D. hansenii) can enhance immunity and resistance against A. hydrophila, and CAT and heat shock protein 70 genes were up-regulated before and after infection of A. Hydrophila. Expand
Effects of dietary live yeast Debaryomyces hansenii on the immune and antioxidant system in juvenile leopard grouper Mycteroperca rosacea exposed to stress
TLDR
Results show that a diet supplemented with D. hansenii stimulates the immune system of juvenile M. rosacea thus enhancing their resistance against A. ocellatum, and fish that received the yeast supplement in their diet have an enhanced immune response as compared with their control counterparts. Expand
Effect of Dietary Protein Level on Growth and Body Composition of Juvenile Spotted Sand Bass Paralabrax Maculatofasciatus, fed Practical Diets.
TLDR
The use of a practical diet containing at least 45% protein is appropriate for growth of spotted sand bass juveniles and no significant difference among dietary protein levels was detected for the other growth variables measured, nor for the proximate composition of the whole fish, liver, or muscle. Expand
Digestive enzyme response to supplemental ingredients in practical diets for juvenile freshwater crayfish Cherax quadricarinatus
TLDR
Results suggest that C. quadricarinatus can modify hepatopancreatic enzyme levels in response to different compounds in the diet and can digest a broad variety of ingredients, particularly starch. Expand
Apparent digestibility of dry matter, protein, and essential amino acid in marine feedstuffs for juvenile whiteleg shrimp Litopenaeus vannamei
TLDR
The most digestible feed ingredients for whiteleg shrimp were: fish soluble protein concentrate, squid meal, shrimp head meal, Catarina scallop by-product meal, and fish meal A (sardine 66% CP) showing that these ingredients are good sources of available protein and amino acids for juvenilewhiteleg shrimp. Expand
Nutritional value of cowpea (Vigna unguiculata L. Walp) meals as ingredients in diets for Pacific white shrimp (Litopenaeus vannamei Boone)
TLDR
Cowpea meals are good sources of nutrients and can be used as ingredients in diets for Litopenaeus vannamei, and cooking and extrusion significantly increased dry matter, protein and carbohydrate digestibility in the diets. Expand
Studies on the Nutrition of Spotted Sand Bass Paralabrax maculatofasciatus: Effect of the Dietary Protein Level on Growth and Protein Utilization in Juveniles Fed Semipurified Diets
TLDR
The results indicate that spotted sand bass juveniles with 2.5-g mean weight need at least 55% dietary protein for best growth when casein is the sole protein source, but in terms of feed conversion ratio, the requirement apparently could be lower. Expand
Development of digestive enzyme activity in larvae of spotted sand bass Paralabrax maculatofasciatus II: Electrophoretic analysis
TLDR
The results indicate that the important digestive enzymes develop rapidly in these larvae, supporting the possibility of early weaning at day 12 ah using artificial diets. Expand
