Short-term forecasting of the result of fishery on the Amur salmons gen. Oncorthynchus

Abstract

Usefulness of operational data on catch of pacific salmons for forecasting of their annual landings is considered. The landing dependence on daily and cumulative catch is analyzed. The former index has better correlation with the annual landing in the beginning of the fishery season but later loses this advantage. The landing relationship with the latter index increases naturally with time and rather reliable forecasts could be based on its value from early July for pink salmon, from middle July for summer chum salmon, and from middle August for fall chum salmon.
