EU standing request on catch scenarios for zero-TAC stocks; cod (Gadus morhua) in divisions 7.e–k (Celtic Sea)

Technical Service

  

Cod (Gadus morhua) in divisions 7.e–k is a target species in the EU multiannual management plan (EU MAP; EU, 2019). The zero-catch advice provided by ICES for this stock is based on precautionary considerations. The mixed-fisheries analysis shows that cod is caught in most mixed fisheries in the Celtic Sea with other species for which non-zero catches are advised. The present technical service provides illustrative catch scenarios consistent with the lower FMSY range for haddock as detailed below.

For cod in divisions 7.e–k:

· 1002 tonnes are estimated to be caught when haddock is fished at FMSY; this would result in a cod spawning-stock biomass (SSB) of 1261 tonnes in 2024;

· 717 tonnes are estimated to be caught when haddock is fished at FMSY lower; this would result in a cod SSB of 1671 tonnes in 2024;

· 869 tonnes are estimated to be caught when haddock is fished midway between FMSY and FMSY lower; this would result in a cod SSB of 1450 tonnes in 2024;

The haddock FMSY , haddock FMSY lower – FMSY, and haddock FMSY lower scenarios result in an increase in cod SSB relative to 2023 (1053 tonnes). All scenarios result in an SSB below Blim (4200 tonnes) in 2024.

It is not possible to provide catch scenarios that include changes in the fishing pattern. The above scenarios assume a fixed fishing pattern in 2023 [based on average (2019–2021)]. Future changes in the fishing pattern depend on management measures and the response of the fishery, which cannot be predicted by ICES.

Since cod are bycaught in mixed fisheries, a specific monitoring TAC would likely not be required for this stock.
