DEPENDENCE OF CATCH VOLUMES, GENERATIONS YIELD, AND SPAWNING START TERMS OF THE NORTH-OKHOTOMORSK HERRING ON ICE CONDITION
The North-Okhotomorsk herring yield and catch are considered in relation to ice condition and based on the 1978-2010 MagadanNIRO materials. It is shown that yield of herring generations in the northern part of the Sea of Okhotsk lies in the inverse dependence on the ice coverage of this area in the year of the generation birth. The Gizhiga-Kamchatka herring catch lies in the inverse dependence on the inter-annual dynamics of the ice coverage of the Sea of Okhotsk. Such dependence for the Okhotsk herring is not revealed within the analyzed period. Dates of herring spawning in the northern part of the Sea of Okhotsk depend directly on the ice coverage.
