Discarding of small redfish in the shrimp fishery off Port au Choix, Newfoundland 1976-80
The quantities of small (~25 ern) redfish Sebastes sp., caught and discarded off Port au Choix, Newfoundland, in 1976-80 were estimated from monthly sampling at sea of the catches of Newfoundland trawlers engaged in this fishery, in ordertoassess the impact of these discards on the redfish stock of...
