The first set up is a standard 20-25 pound test rig (depending on the size of the tuna) with a size 1 to 2/0 hook depending on bait size and the size of the tuna. Fluorocarbon leader can be super effective if the fish are touchy (biting infrequently). This set up will be the primary bait fishing set up.
Typical Serving Size. A typical serving size of fish can range from 3 to 6 oz, depending on the type of fish and its preparation. The American Heart Association considers 3.5 oz. of cooked fish, or about 3/4 cup, to be a single serving. A can of tuna contains about 5 oz. and lists 2 oz., or 1/4 cup, as an appropriate single serving size on the nutrition label.
