lobster traps farming techniques
a) site selection

　　 lobster traps set locations should be selected in sheltered sunny, fresh water, waves small, relatively quiet, no pollution, moderate amount of water exchange, at the micro-water as well, around the open, no water rat location.

　　 (two) lobster traps materials and management

　　 lobster traps more polyethylene or nylon material mesh material. mesh size according to the size of the individual to decide crab
given to the principle of not escape crab, each lobster traps area of 30 square meters is appropriate. net sealed lid above the lobster traps at the top and bottom of the left two for the switch hole, and with a nylon zipper sewn on to the switch, feeding checks. lobster traps at the bottom left of the hole, usually shut, etc. lobster traps at the bottom of a large number of epiphytic algae or sludge adsorption is large, open promptly removed, scrub attached lobster traps dirt on the algae in order to ensure a regular exchange of water bodies. at the same time, can also belobster traps flip bottom up, reseat lobster traps, the original cover shut, open the bottom of the cable fed diets to ensure lobster traps mesh smooth. to prevent epiphytic algal blooms, but also in lobster traps within 10 xenocypris raising fish, 5 ~ 10 tilapia to remove lobster trapscontaining algae and so on. manual scrubbing lobster traps when the operation should be careful to prevent damage to the crab appendages.
(three) lobster traps set

after setting lobster traps, the four corners with four bamboo insert the mud, lobster traps in the corners with a rope fixed on bamboo. corners with stones as sinker with a rope leash, sink to the bottom. adjusting the length of the rope, the lobster traps fixed at a certain depth of water can lift, adjustable depth, to prevent water waves will be lobster traps washed away, ensuring lobster crab traps safe and reliable. lobster trapsplaced depth, depending on the season, the weather, the water temperature may be. spring and autumn, you can put water depth 30cm ~ 50cm or less, seven, eight, nine months high temperature, the water temperature is high, lobster traps can be placed 60cm ~ 80cm less, lobster trapsabove to put fresh water plants, increasing shade area for crab xieliang.

　　 (four) stocking density

　　 lobster requirements specifications and tidy crab traps, crab body robust appendages. stocking density based on water quality, bait
materials, management case may be, to manage water quality live bait foot, excellent quality and you can put on the contrary, it put less. crab specification 150 / kg ~ 200 只 / kg as well, density 20 / ㎡ ~ 25 / m, a lobster traps put crab 5kg (600 只~ 750 or so), according to 70% of the recapture rate, each lobster crab traps can produce 50kg ~ 60kg, but also a small amount of adult fish integrated programme.

　　 (five) feeding method

each lobster traps to be set up within a two square meters around the bait station, a twice daily feeding times. nutrition proportional allocation by various food, chopped cooked, put the other diets, with the right amount of flour shape into groups, blocks, slabs feeding, which can improve feed efficiency, reduce waste and pollution of water bodies, but also to facilitate check the feeding situation. feeding situation next morning a slight surplus for the degree. to ensure food feed, palatable, to prevent cannibalism. the ratio of the bait on the first half of the main plant food, animal feed amount. dominated the second half of animal feed, vegetable supplement, promote the growth of fattening.

strengthen inspection and management, timely removal of the bait and found that lobster traps timely repair damage, to prevent escape crab. have
dead crabs should be taken out, so as not to affect the water quality.
