Estimated production, catch per unit effort, biological aspects of tuna, skipjack, and small tuna in North Sumatra

Tuna and like species resources are like other renewable resources. The level of exploitation of these resources dramatically affects their ability to maintain their numbers and abundance in the water. Fishery management policy should be conducted based on a scientific-based approach. This research...
