ESTIMATION OF NORTHEAST ATLANTIC BLUEFIN TUNA (THUNNUS THYNNUS) GROWTH PARAMETERS FROM TAGGING DATA

Biscay (North of Spain) have been analysed to estimate the von Bertalanffy growth parameters of this species. Growth models incorporating individual variability in growth among individuals and model error have been applied. The results provided were L ∞ =281.9 cm and K=0.10. A bootstrap of the data...

Description
Summary:Biscay (North of Spain) have been analysed to estimate the von Bertalanffy growth parameters of this species. Growth models incorporating individual variability in growth among individuals and model error have been applied. The results provided were L ∞ =281.9 cm and K=0.10. A bootstrap of the data resulted in large standard errors for these parameter estimates. The estimates currently adopted for the stock fell within the bootstrap ranges. It is concluded that these data could contribute useful information to future studies on growth for the stock.
