The hydrological characteristics of the coastal area are described in four areas: 1) the northern part of Aniva Bay — Lososy Bay, 2) the southeastern part of Aniva Bay, 3) stone-rocky coast of southeastern Sakhalin and 4) open sandy coast of southeastern Sakhalin on the results research in 2017–2020. The stage-by-stage (from the second decade of May to the first decade of July) variability of the structure and production parameters of zooseston was analyzed. The variability of the coastal ichthyofauna and the feeding of planktophagous fish are described. The calculation of the receiving capacity for smolts of Pacific salmon (pink salmon and chum salmon) has been made. In the northern part of Aniva Bay (section 1), the receiving capacity for smolts of chum salmon is estimated as 335 million units, for smolts of pink salmon as 426 million units. The receiving capacity of the southeastern part of Aniva Bay for smolts of chum salmon is estimated as 78.3 million units, for smoltsof pink salmon as 398,3 million units. The receiving capacity in section 3 above a depth of 0–3 m for smolts of chum salmon is about of 138,7 million units, for smolts of pink salmon about of 129., million units. The receiving capacity in section 4 above a depth of 0–3 m is about of 18,2 million smolts of chum salmon and about of 67,2 million smolts of pink salmon
