Industrial fishing and climate variability

Using harvest and spawning data from 22 North Atlantic cod (Gadus morhua) fisheries, researchers report that fishing pressure may lead to large-scale synchronous fluctuations in marine fish populations that are comparable to shifts in population size attributed to climate variability, suggesting that fishing exploitation may be a driver of stock size variability for heavily exploited fishes. - Read at
