The Impact of Water Circulation on the Year-class Abundance Dynamics of Redfish and Cod on the Flemish Cap

摘要: This paper studies the formation of abundance redfish (Sebastes spp) and cod (Gadus morhua) year-classes under varying conditions spawning, which a key role is played by water circulation. A statistically significant relationship (r=0.601, p=0.002) between survival atmospheric cyclonic activity was revealed. based on effect storms circulation over Flemish Cap supports hypothesis impact year-to-year variation in Taylor column survival.By contrast with cod, larval to large extent related position North Atlantic Current, impacts main spawning grounds (southern slopes bank) correspondingly may influence drift larvae away from bank. supported reciprocal (r=-0.565, p=0.012) rate northern front Gulf Stream latitude south Grand Banks near 51°W.The emergence very strong Div. 3M likely be more hydrographic rather than status stock.
