The extraocular muscles must turn each eye inward; the sphincter muscles must work to make the pupil smaller; and the ciliary muscles must contract to allow the lens to change to a shape that will produce a clearer image. Solution: Focus on a distant object to immediately feel your eyes relax.
Its upper body is blue, the belly is silver, and the fins are yellowish-gray. The common amberjack can reach five to six feet (1.5 to 1.8 m) in length and more than 100 pounds (45 kg) in weight. The average weight, however, is 10 to 15 pounds (4.5 to 6.8 kg).
RE: Amberjack Setup? I use a Penn Torque 300, 80 lb PP with a bimini twist at the end, 50-80 lb fluoro leader tied to the bimini with an albright knot, mounted on a 7' Chaos T-80 jigging rod. Works well with jigs and also with carolina rigs...lots of backbone, lots of drag, lots of torque.
