Preliminary Assessment of the Stock Status of Atlantic Bonito (Sarda sarda) in the Northeastern Part of the Atlantic Ocean

Abstract
Based on the Russian fishery-biological data, an attempt was made to assess the stock status of Atlantic bonito Sarda sarda in the northeastern part of the Atlantic Ocean using the length-based spawning potential ratio (LBSPR) method. Values of the parameters of the Bertalanffy equation are calculated for Atlantic bonito: the theoretical maximum length of an individual is 75.6 cm and growth coefficient is 0.41. The values of the length where 50 and 95% of the fish are mature are 44.7 and 57.0 cm, respectively. The resulting estimate of the spawning potential ratio (0.28) is lower than the biological target reference point (0.40) and formally indicates an overfishing status of the stock.
