Caught and released: an Overview of fishes’ sensitivity to being discarded as a tool to aid Pursuing Ecosystem-based management 2 (COPE2) (39796)

Project Details


The project aims at estimating discard survival for undersized plaice in the Baltic (areas 24 and 25) otter bottom trawl fleet, following ICES guidelines so that the discard estimate may be used to document a high survival exemption. We will sample undersized plaice in commercial conditions, and observe their mortality in captivity (up to 21 days until the mortality levels off). Experimental conditions will include the two legal codends (mesh size of at least 120 mm constructed from T90, or at least 105 mm fitted with a BACOMA exit window of 120 mm), as well as key environmental conditions known to affect discard survival.
