In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. On average, in adult males, levels of testosterone are about 7â8 times as great as in adult females.
Rig for the kind of fish you want to catch. How you rig depends partly on the kind of fish you hope to catch. Catfish usually search for food near the bottom, so you need weight to keep your bait near the fish. Crappies and many other panfish often swim a few feet beneath the surface, and a bobber will hold your bait up where the fish can see it. Keep it light.
How to make a two-hook bottom rig for larger fish: 1  Use 50- to 100-pound fishing line (any type) for leader, a snap swivel, two three-way swivels and a regular swivel. 2  Add the snap swivel to your main line.  Tie a 6- to 8-inch piece of leader to the snap swivel using one of the fishing knots.
