On the lobster traps grass carp breeding techniques

Keywords: lobster traps grass carp breeding techniques
Abstract: Luoma is a typical over-water lake, an area of 260 square kilometers (water level 23.0 m), lobster traps pen culture area 26.7 square kilometers, in recent years, driven by aquaculture demonstration households, lake fishermen engaged in lobster traps farming unprecedented enthusiasm, and because the lobster traps grass carp fast growth, high yield, good benefits, sales Chang, mostly lobster traps grass carp dominated, especially in Clearwater Lake City Soap Lake the most prominent.Now lake lobster traps grass carp technical points are summarized below.
First, the water environment
lobster setting lobster traps grass carp traps waters should choose sunny leeward, away from the mining area, to avoid the impact of industrial and urban pollution, water wide, the water level stable, maintaining more than 5 meters depth, clean water, adequate dissolved oxygen, pH, 7.0 to 8.5,water transparency at 50 cm or more, dissolved oxygen at 5 mg / l, flat bottom culture zones, clay, small waves, and to avoid flood water areas and weedy areas, there are micro-water, less susceptible to floods, high winds destroyed.
Second, lobster traps choice
(A), lobster traps Specifications
The lobster breeding of grass carp traps specifications generally use 10 × 10米, 8 × 10 m and a height of 2.5 to 3 meters. lobster traps should be plaited polyethylene material, double-layer structure, the cover for the single network, the inner mesh of 3 cm to 3.5 cm, outer mesh is 4 cm.
(Two), lobster traps structure
lobster traps used material for the polyethylene material, use more square or rectangular shape, lobster traps are constructed using a floating double layer lobster closed traps, mesh size and length of the fish the relationship: a (mesh leg length) <0.105 L (FISH LENGTH). Each lobster The framework consists of four traps 8-10 m long bamboo rolled together, in order to support the entire lobster traps, sinker stones with long, knot in the lobster traps following four screen angles, so that lobster traps in the water fully developed shape. lobster traps using fixed ropes, cables diameter of 4 cm polyethylene rope, anchor fixed to the frame with the waters. lobster traps through cable fixed, lobster traps on the cover above the water 30 cm ~ 50 CENTIMETERS.
(THREE), LOBSTER TRAPS ANCILLARY FACILITIES
LOBSTER TRAPS ANCILLARY FACILITIES INCLUDE: FLOATING FRAMES AND MATERIALS, FLOAT, SINKER AND FIXED RAFTS FIXTURE. OUTRIGGER GENERALLY USE A COMBINATION OF BAMBOO AS RAW MATERIAL, SHAPE AND AREA UNDER THE LOBSTER TRAPS SHAPE, SIZE MAY BE.
THREE, LOBSTER TRAPS SET
lobster requirements set in the open water traps, leeward, sunny, underwater no debris, convenient place, and tied to a combination of floating wood shelves. lobster traps into the water depth of 2 to 2.5 meters, lobster traps are arranged as a single or dual-row, each column placed lobster traps 3 ~ 5form a raft, row spacing of not less than 5 m. lobster traps into the water 2 -2.5 m, 0.5 m above the surface, to prevent grass carp jump outside the box, lobster traps sew a cover above the net. Net use bamboo lid propped up in order to avoid depression affect the inside grass carp feeding into the water. lobster traps at the bottom corners of the department sinker, then fish with a rope fixed. lobster traps should fingerlings into the box before 10-15 days will net clothing soaked in water, so netting attached to a certain amount of plankton, commonly known as "hanging moss", so that mesh smooth, fingerlings into the box to avoid netting after wiping hurt the fish, because fish into the box generally not suited to, easy to crash, easy to scratch. lobster traps allow single box set or press group settings. Single box set box spacing 25 m or more. Press group settings, each 5 ~ 10 boxes as a group, was tandem, take a single or double row, 5 m spacing within the group box, set spacing of 100 meters. lobster traps arranged in the direction perpendicular to the flow direction. To prevent debris damage lobster traps, the lobster traps breeding waters around the outer circumference should be one week fence.
