CATCH COMPOSITION AND SEASONAL-VARIATION OF SETNET FISHERIES IN THE YELLOW AND BOHAI SEAS

The paper reports on the basic characteristics of the catch compositio n, distribution and seasonal variation of setnet fisheries in the Yell ow and Bohai Seas. There were 126 species in the samples, including 10 2 fish species, 17 crustaceans, 5 Cephalopoda, and 2 Medusa species.
