Integral quantitative assessment of the environmental impact on the NEA cod year-class strength has been made with use of the survival index. Three types of survival conditions with different impact of spawning stock on recruit abundance were difined. There is a significant correlation between the survival index and the spawning stock, the recruitment abundance (40,1%), the water temperature
