How to Farm Freshwater Fish - TvAgro por Juan Gonzalo Angel

Twitter @juangangel The Pacific Northwest's National Forests provide habitat for a variety of Warmwater (both game and non-game) fish. These fish include Sculpins, Minnows, Darters, Bass, Walleye, Crappie and Bluegill. In the past, various warmwater species were called "spiny-rays" because most of them have rigid fin rays (spines). Salmon, trout, char and whitefish have only soft rays. Fisheries managers today prefer the term "warmwater" game fish for the so-called spiny-rays, and "coldwater" game fish for salmon, trout, char and whitefish. Becoming acquainted with identification and habits of these fish will open new fields of interest and opportunity for anglers The body shape of the Walleye is similar to its smaller cousin, the Yellow Perch. There can be no mistaking the two, though. In addition to its larger size, the walleye lacks the dark vertical bars of the perch. Coloration is variable, but generally a dark olive green on the top and sides, blending into a lighter, sometimes pinkish, sometimes white, belly. The sides, particularly above the lateral line, show an irregular pattern of small, dark blotches. One of the first identification marks when landing a walleye is the white tip on the lower lobe of the tail. And the eyes have an almost opaque, "moonish" look. Walleyes begin spawning when water temperatures reach 45F. Also like the perch, fecundity is high, with as many as 50,000 eggs produced per pound of body weight. Walleyes are ravenous feeders. Because their large eyes are adapted to finding prey in low light, they are not often found near the surface except at night or in turbid water Fuente: http://www.fs.usda.gov/detail/r6/plan...
