enzyme activities of the marine shrimp, Penaeus vannamei Boone, were investigated during …

Relationships between protein level, size, apparent feed digestibility, digestive enzyme
activities and growth of Penaeus setiferus were investigated during a 30‐day growth trial …

Protease activities in the hepatopancreas extract (HP) from white shrimp (Penaeus
vannamei) fed one of seven test diets for 30 days were evaluated by several methods. The …

A study was conducted to evaluate variations of digestive enzyme activities in Litopenaeus
vannamei (Boone) reared in commercial ponds under semi‐intensive conditions. Shrimp …

The effect of food composition on the digestive system of Penaeus vannamei shrimp was
used to determine the suitability of feces for analysis of class, type, composition of digestive …

Proteases from the midgut gland of the Farfantepenaeus paulensis juveniles were
assessed. Enzyme activity was determined using protease substrates and inhibitors. The …

shrimp. The assessment of protein digestion through the developmental stages of penaeids …

Due to feed ingestion, maximal organ weight was reached in 1 h after feeding for the foregut,
and 5 h after feeding for the midgut where the highest protease activity was observed in the …

The characteristics of the primary digestive enzymes of the shrimp Penaeus japonicus were
studied in animals fed for 30 days on a compounded dry diet containing 60% protein. Pepsin …
