Abstract
The article considers the issues of current degraded state of aquatic biological resources of the Volga-Caspian Sea basin and provides specific data on commercial stocks of fish. The main reasons for decrease in natural stocks of ichthyofauna are regulation and pollution of the spawning rivers, adverse hydrological conditions, injudicious hunting, poaching pressure. To improve the state of natural stocks of fish it is necessary to increase their reproduction and implement measures to restore and rational exploitation of aquatic bioresources of the Volga- Caspian Sea basin.

Abstract
Potentiometric titration method was used to study quality complex formation between low methylated pectin and proteins concentrated from whey. It’s shown that at рН>IEP of the lactoglobulin the interaction occurs between negatively charged chains of LM-pectin and positively charged patches of polypeptide chains. The biopolymers ratio had no significant effect on the initial pH of soluble complex formation (pHc); addition of sodium chloride decreased pHc and pK0 of complexes, which linked to electrostatic nature of complex formation between LM-pectin and whey proteins.
