The expressions of trypsin and chymotrypsin in the pyloric caeca of Atlantic salmon (Salmo salar L.) were studied in three experiments. Two internal (trypsin phenotypes, life stages) and three common external factors (starvation, feeding, temperature

The responses of the digestive proteases trypsin and chymotrypsin and protein metabolism to differences in feed protein quality were investigated in Atlantic salmon (Salmo salar L.). Two sets of experimental feeds were produced. Each set of high and

Two successive experiments were conducted in order to assess plasma free amino acid (FAA) profiles as a method for evaluating protein quality of fish feeds for Atlantic salmon, Salmo salar (L.). In experiment 1, the importance of meal size and inter-

Biochemical structure of protein (reactive SH content, content ratio of SH/S-S and concentration of D-Asp as % of total (D+L)-Asp) indicating digestibility of dietary protein was changed under different processing conditions. Based on fish crude enzy

The aim of the present experiment was to screen several biochemical indices in fish and their interrelations in order to select variables for future studies of growth rate and feed conversion. Several parameters [trypsin activity, chymotrypsin activi

We show significant relationships between digestion rate of dietary protein, absorption/transport rate of amino acids, and plasma insulin concentration. Digestion rate of dietary protein was indicated by protease activity ratio of trypsin to chymotry

Genetic variation in responses to vaccination of both specific and non-specific immune parameters were observed in individual Atlantic salmon, possessing different trypsin isozyme patterns in the pyloric caeca and exhibiting different growth rates. T

Growth was found to be associated with the changes of trypsin activity in the pyloric caecal tissues and the level of plasma insulin in Atlantic salmon (Salmo salar L.). A decrease in trypsin activity accompanied by an increase in plasma insulin was

Hatching and start-feeding temperatures affected the expression of different trypsin isozymes in the pyloric caeca of Atlantic salmon. Hatching temperature of 10 °C induced the expression of the common isozyme TRP-2*100, and of 6 °C induced the var
