Assessment of cod in division 4X in 2000 / D.S. Clark, S. Garvaris and S.D. Paul. : Fs70-1/2000-139E-PDF
Landings and total allowable catch (TAC) have declined throughout the 1990s, and were the lowest on record in 1999. Exploitation rate declined from the high of 60% in 1992 to about 23% in 1999. Age 4+ biomass has remained stable at a low level since 1996. The recruiting 1998 year-class is the strongest since 1992, initial indications are that the 1999 year-class is at least as large. With removals of 6,000 t in 2001, there is a 50% chance of a 20% increase in the 4+ biomass between 2001 and 2002, due to improved recruitment. The 1999 year-class must be at least as strong as the 1998 to approach the growth implied by the three-year rebuilding plan.
