Abstract

The study of the properties of the PepT1 proton-dependent oligopeptide transport system in the fish intestine is a promising direction to solve the problem of the replacement of dietary proteins in aquaculture. At the same time, some publications provide direct evidence for the close relationship of the processes of oligopeptide absorption in the fish gut with the parameters of plastic metabolism in various organs and tissues, especially in the early stages of ontogeny. The published data suggest that the food value of synthetic oligopeptides for fish may be increased by including amino acids that are growth limiting for a given tissue in the early stages of ontogeny of a fish species. Finding the parameters of the affinity of individual substrates (oligopeptides) to the PepT1 transport system in fish will contribute to solving this problem in aquaculture.
