Anxiety doesn't necessarily cause concentration problems as its own symptom. In fact, it could be argued that anxiety actually improves concentration.

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.

Full Answer. The average size of a tuna fish depends upon the species of the tuna fish. An albacore tuna fish averages around 15 to 40 inches in length and has a weight of approximately 10 to 25 pounds. The Atlantic or northern bluefin tuna, one of the largest species, weighs around 550 pounds. Other species of tuna include the southern bluefin, bigeye, bonito, skipjack, tongol and yellowfin tuna.
