Abstract:
Dynamics of the fishable biomass of the Barents Sea cod in 2000-2007 were stable, with an upward trend in recent years (2005-2007). The result of a correlation analysis made is that the "parents-progeny" relationship is not provided with a significant level, whereas the recruitment of cod aged 3 is directly related to the mean water temperature within 0-200 m, and correlation coefficient was 0.68. The analysis of the dependence of recruitment on water temperature was made formal which enabled us to generate a prognostic model, and evaluate the size of recruitment at age 3. The estimated fishable biomass forecat and TAC for cod of the Barents Sea based on GIS method showed that a possible yield in 2008 will be 629 thousand tons which is 1.5 times greater than it had been suggested by the AFWG.
