A study of bottom-trawl discards in Queen Charlotte Sound and Hecate Strait, 1981 and 1982 / by R.D. Stanley. : Fs97-4/1840E-PDF

"The B.C. domestic trawl fishery does not retain all sizes and species of fish which are captured during routine commercial fishing. The fish which are not retained for sale are discarded at sea, often in a stressed, injured or moribund state. The discarded portion is composed of species for which there is a limited or no market, species which are prohibited from retention by trawlers, and non-marketable juveniles. The amount of discards relative to landings can vary greatly over time and space, and among fisheries for different target species. However, observations from Queen Charlotte Sound and Hecate Strait in 1981 and 1982 indicated that, averaged across trawl fisheries, approximately 40% of the catch was discarded at sea. The quantities of individual species were shown to be large enough to warrant serious consideration by stock assessment biologists"--Abstract, page iii.
