Yellowtail Flounder Length at Maturity in the Grand Bank (1995-98)
In this paper yellowtail length at maturity estimates based data collected in the spring Spanish surveys in the Regulatory Area of Divisions 3NO are presented. Female length at 50 % maturity decreased from 35 cm in 1995 to 23 cm in 1998. In males, this parameter decreased from 23 cm in 1995 to 19 cm...

| Sumario: | In this paper yellowtail length at maturity estimates based data collected in the spring Spanish surveys in the Regulatory Area of Divisions 3NO are presented. Female length at 50 % maturity decreased from 35 cm in 1995 to 23 cm in 1998. In males, this parameter decreased from 23 cm in 1995 to 19 cm in 1998. The differences in L50 estimates in females were significant between 1997 and the previous years , and between 1998 and both 1996 and 1995, and were not significant between 1997 and 1998. In males, differences were significant between all the years, except between 1997 and 1998. The covariance analysis between the linearized maturity curves were highly significant in both sexes. |
