Rainbow trout is a kind of cold-water fish, which likes to inhabit slow-flowing rivers, lakes and other water bodies. The optimum water temperature 12 ~ 18℃ is carnivorous. In the fry stage, they mainly feed on zooplankton and aquatic insects. Adult fish mainly feed on fish, crustaceans, benthos and aquatic insects. Also eat the leaves and seeds of aquatic plants.

The mainstream fishing method of rainbow trout is floating fishing, because rainbow trout is a medium-sized fish, but the change of season, the change of water temperature, the level of air pressure and the bait environment will change the active water layer of rainbow trout, so sometimes it is necessary to catch it to the end. The easiest way is to search from the bottom up gradually until the fish in the middle can stabilize, which means that the fish layer has been found.

Rainbow trout mainly includes hand fishing, ice fishing, reed bud fishing and other fishing methods. The fishy baits such as river shrimp, earthworm, small fish and chicken liver can be used for hand fishing and ice fishing, and the simulated baits such as lead head hook fishing group (lead head hook and tail-winding maggot), Dezhou fishing group (bullet lead, bead blocking, crank hook and soft bait), sequins and MINO can be used for reed bud fishing.

The mainstream fishing method of rainbow trout is floating. Rainbow trout salmon is a kind of freshwater fish, named after the adult fish has a rainbow-like brown-red longitudinal stripe along the lateral line. I like to live in the middle layer of rivers, lakes and reservoirs with clear water quality, low water temperature and rich dissolved oxygen. The mainstream fishing method is floating fishing, and sometimes it is necessary to catch it to the end. The easiest way is to gradually find the fish layer from the bottom.

morphological character

Adult rainbow trout can weigh about 2.8 kilograms. The main appearance basis for distinguishing male and female rainbow trout is the head, where the head is sharp and the mouth is blunt and round. Dorsal fin ⅲ-9 ~10; Gluteal fin ⅲ-10; Pectoral fin Ⅰ-15 ~16; Pelvic fin ⅰ-10; Tail fin X- 17 X gill rake 8+12; The vertical dimension is about135; Gill striate bone is about 12.

Specimen length 104.9 ~ 140.5 mm. Long body, medium lateral flat; Body length is 3.8 ~ 4. 1 times of body height and 3.6 ~ 3.7 times of head length; The body height is 0.9 ~ 2.3 times of the body width of 65438+. The head is also flat and taller than the height; The length of the head is 4.3-4.7 times of the length of the kiss, 3.9-4.3 times of the eye diameter, 3.3-3.5 times of the eye spacing, and the length of the tail stalk is 1.7-2 times.
