2. lobster traps shape
A rectangular, square, cylindrical, octagonal, etc. Commonly used in current production of rectangular and square, because of its ease of operation, over the water area, making convenient.
3. lobster The size of traps
The smallest lobster traps area of about 1 square meter, usually 1-15 meters of lobster is a small lobster traps traps, lobster traps area of 15-60 square meters of medium-sized lobster traps, large lobster traps area of 60-100 square meters, bigger 500-600 square meters. Generally speaking, lobster traps of the area should not be too big, too big to maneuver, wind power is poor. But too small lobster traps yield is high, but the cost is high. At present, most using a 2 0 - 4 0 m2 sized lobster traps, the 5 4m, 5 5m, 6 6 , 6 5 meters, and other specifications.
4. lobster traps height
lobster traps based on the height and depth of the water body to determine the vertical distribution of plankton. At present, many with a high 2.5 - 3 m between. Deep water can also be used about 2-4 m high lobster traps. But lobster tra ps bottom and bottom to a minimum distance of 0.5 m or more, so that the bottom of the waste from lobster traps.
5. Mesh size
Cabinet mesh size should be based on the object to determine breeding to try to save material, but also to achieve lobster Water traps highest exchange rate policy. Mesh is too small, not only the lobster traps increased costs, but also affect the water exchange updates; mesh is too large, the phenomenon has emerged escape of fish. Usually fry fish stocking 4 cm, 1.0 cm with a mesh of lobster traps; stocking 11-13 cm in an age of fish, with a 2-3 cm lobster mesh traps; develop fish lobster traps, with 3-5 cm mesh lobster traps. In order to make unobstructed water exchange to reduce lobster traps flush times, preferably with fish grow up, switch to a larger mesh lobster traps.
(Two) lobster traps devices
1. lobster traps device type
By lobster traps in the form of devices can be divided into fixed lobster traps, floating lobster traps, sunken lobster traps. The county is mostly enclosed floating feeding lobster traps 5m 5 m 3 m, above the netting cap closure, mesh cover has a 50 cm 60 cm breadwinner, usually closed to fishing to live on when you unlock.
(1) floating lobster traps
Cabinet mesh outline four weeks on tying the knot in a bamboo or steel pipe tied into the frame, mesh outline four weeks under the department sinker, frame ends with a rope tied together with anchors, catchy sealed with mesh , sub-frame tie floating, floating on the water surface.
lobster traps simple structure, material representing provinces, wind power is strong, able with the water level, wind, water and float freely. Generally set in the open water, the water level is unstable, and from vessels less water.
Floating lobster traps have a single box and multi-box floating floating. Single box floating a single box set one location with a single anchor or double anchors. Its good water exchange, to facilitate transfer case and cleaning lobster traps, but wind power is poor. Boxes of floating is 4,8,12,16,20,24 ...... a series into a cabinet, with both ends fixed anchors, between rows strong links with frame material, each column lobster traps should be greater than the distance between 10 meters away. This method takes less water, management is relatively concentrated, suitable for large-scale development, but the production as effective as single box floating.
(2) Fixed lobster traps
Normally open type lobster traps, the piles and rail links into frames, lobster traps hanging in the frame, the outline is not installed float, lobster traps the upper and lower corners top and bottom of the pile hoop coupling or pulley, easy to adjust the lobster traps down and wash boxes, fishing and so on. 0.7-1 m above the surface of the body mesh, mesh body underwater 2 -2.5 m. Usually with the water level down box can not be raised and lowered, this method is only applicable to small changes in water level shallow lakes peace prototype reservoir. Advantage of low cost, easy to operate, easy to manage, wind resistance, the disadvantage is not migrate, it is difficult to set in deep water, and lobster traps inside the fish habitat varies constantly with the water level changes, such as not pay attention to timely adjustment will affect the feeding effect.
(3) sink style lobster traps
Whole lobster sunk in the water traps predetermined depth. Changes in water level network itself is not affected, mesh attachments less affected by wind and waves, water impact, suitable for sea water lobster big fish traps and storm locations. Drawback is that maneuver, fish growth rate and low level of production.
