Exploitation
 

Redfish is nowadays caught in bottom trawl fisheries at intermediate depths. In turn, redfish are also caught as bycatch in fisheries directed for cod and Greenland halibut. The fishery in NAFO Div. 3M is regulated by minimum mesh size and quota.

Recent catch estimates and TACs (000 t) are as follows:

Projection

Short term (2018-2019) stochastic projections were carried out for female spawning stock biomass (SSB) and catch, under most recent level of natural mortality and considering four options for fishing mortality (F0, Fstatusquo, F0.1 and Fmax). Projections were initialized at the beginning of 2018 assuming Fstatusquo during 2017. Recruitment entering in 2017 and 2018 is assumed constant at the geometric mean of below average recruitments (age 4 XSA, 1989-2014).

In all projections scenarios spawning biomass remains at relatively high levels.
Assessment Model
Analytical assessment
Results

Input data comes from EU Flemish Cap bottom trawl survey and the fishery and is considered good quality. A quantitative model (XSA) introduced in 2003 was used. Elevated natural mortality was assumed from 2006 to 2010 but was low (more typical of redfish) otherwise. In order to include an independent approach to natural mortality in the 2017 sensitivity M framework, the actual beaked redfish natural mortality has been estimated by a number of published models

The next full assessment of this stock will be in 2019.
