Includes bibliographical references (page 8). "Research surveys indicate that stock biomass has levelled out, or is increasing very slowly. Commercial catch rates on the other hand are down in 1983 and 1984 from the high levels in 1980-1982. The catch was again substantially less than the quota. A terminal fishing mortality of 0.4 was used for catch projections. The projections are that F0.1 catch in 1985 will be 14,000 t if the TAC is taken in 1984, or 15,500 t if the F0.1 is taken in 1984. Either way this catch will be predominantly of 5 year old fish. It is clear both from the poor tuning relationships and the historical underestimation of stock size that this assessment is essentially an informed guess"--Abstract. Includes abstract in French.
