FSP North East Coast Discards Survivabilty

Abstract

The objective of this study was to assess whether various species of fish survive being caught and then being discarded during normal commercial fishing practices. This was a scoping study to examine the potential of discard survival in gadoid fish. To examine whether immediate survival is present after capture and to determine the scope for further research into long term discard survival of gadoid fish.

Lineage

The FV Emulator fished using a standard commercial otter trawl. The vessel deployed a Whitby Jet otter trawl, which is used extensively by vessels off the NE coast to fish for cod. The net had a fishing line of 26m (84ft) with a 23m (76ft) headline. The net lifting bag mesh is 260mm, with a codend mesh of 120mm diamond, constructed from 4mm double-braided twine. The fishing vessel Emulator fished as per normal for commercial fishing practice (Annex 1). The survey took place over 6 days. For the first 3 days, fishing took place in depths of 44-51 meters (i.e. in depths of less than 30 fathoms), for the remaining 3 days; fishing took place in depths of 55-64 metres (i.e. in depths of greater than 30 fathoms). To measure the vitality (health) and therefore survival potential of commercially caught fish species, observers assessed individual fish and scored their ‘vitality’ using two semi-qualitative assessments methods. The first method being a score on a four level ordinal scale based on an assessment of individual fish within a few seconds were fish were scored as excellent, good, poor or moribund (see table 1). The second method employed on individual fish was to use a binary scoring system to identify presence or absence of a particular response or injury.
