Though anglers have recently reported excellent bluefin tuna fishing off California due to favorable water conditions and an abundance of anchovies, the total population of Pacific bluefin remains in very poor shape, experts say. Many small fish are caught by Japan, Korea, and other foreign countries on the western side of the Pacific, and large breeding fish are caught by Taiwan and Japan on the spawning grounds. Once bluefin arrive in the eastern Pacific, they experience commercial pressure while in Mexican waters.
The CCA CAL team expects to plan additional tagging trips with Block and her associates in the future. Having accurate spawning-age information plays a critical role in solving the management challenges of bluefin tuna across the Pacific basin.
