What method of fishing is usually used for surface-swimming fish, like salmon, sardines, mackerel, or tuna?
Explanation
Answer: B - Purse-seine fishing is usually used for surface-swimming fish, like salmon, sardines, mackerel, or tuna.
Key Takeaway: In purse-seine fishing, one or more boats in a fishing fleet cast a large net under and around a whole group of fish. The net usually looks like a purse or a bag with a draw-string. The fishers then pull the net in and retrieve the fish. This is usually used for pelagic (surface-swimming) fish like anchovies, sardines, salmon, tuna, and mackerel.
