Incidental catch of marine birds in the north pacific high seas driftnet fisheries in 1990 Incidental catch of marine birds in the north pacific high seas driftnet fisheries in 1990
The incidental take of marine birds was estimated for the following North Pacific driftnet fisheries in 1990: Japanese squid, Japanese large-mesh, Korean squid, and Taiwanese squid and large-mesh combined. The take was estimated by assuming that the data represented a random sample from an unstratified population of all driftnet fisheries in the North Pacific. Estimates for 13 species or...
