| Summary: | This document shows the results of Likelihood ratio test for the statistical comparison of northern shrimp growth curves built from length distribution in EU surveys and from commercial fisheries between the years 1994 and 2005 in 3M Division. Although the analysis showed growth differences in the oldest year classes between the two sources of samples, the absence of significant differences since 1994 in the growth curves estimated by EU survey and Commercial fishery would allow us to use the EU survey length distribution to estimate the age composition of the catches carried out by international fleet directed to shrimp fishery in 3M Division. |
