Maturity of female cod in 2J3KL
By J. Morgan; J. Brattey
Abstract
This study extends the time series for estimates of proportion mature at age for 2J3KL female cod to Jan. 1 1996, as well as presenting the observed proportion mature at age in each year for each Division. The proportion of mature fish at age has been increasing in all Divisions and in the stock as a whole, with the increase being greatest since the early 1990's. As a result, the estimated age at 50% maturity has decreased from over 6 to a low of 4.86 in the most recent 2 years. A comparison of proportion mature at age and length in the surveyed area in Div. 3L in fall 1995 with data from western Trinity Bay does not show a significant difference between the two areas.
