| Abstract: | This project was designed to predict penaeid shrimp yield in the Bohai Sea in autumn by means of multiple regression equations
based on the data of abundance index obtained from the trawl surveys in the main spawning ground of shrimp in the Bohai Sea
and the nursery grounds of juvenile shrimp (Bohai, Laizhou and Liaodong bays and the Luanhe River estuary) in early August
every year from 1965–1982. The prediction method and its use are presented in this paper.
The abundance indexes obtained from the four sea areas as four independent variables, when subjected to an F test, showed
that they had significant effects on the penaeid shrimp yield in the Bohai Sea in autumn. |
