How to keep crayfish can live longer

Crayfish can live a little longer method of large pots live method, glass tank live method and so on.

1, large pots live method

Because the crayfish are more aggressive, so try to use a large pot spread to place the crayfish, large pots into the right amount of water (the water surface does not go over the top of the head of the crayfish, you can be about 2-4 centimeters), into the right amount of water so that you can not only reduce the number of deaths, but also allow the crayfish to discharge the body! Garbage, crayfish prefer dark and humid places, you can cover the pot with a black plastic bag or something else, raise crayfish during the crayfish can feed some green leaves, steamed bread, diced meat.

The lobster rinsed, poured directly into the pool with an air pump or glass tank oxygenation, lobster do not put too much, morning and evening water change, this storage method can store lobster 5-10 days.

Culture crayfish management process:

1, pond

Pond depth control between 1-1.5m, flat bottom, compacted around the pond to prevent lobster escape, pool slope ratio of 1:2.5. before stocking, each acre of pond using 100-150kg of quicklime to clear. -After 3 days, the pond is fed with water. 10 days later, 300-500kg of decomposed organic fertilizer is applied to each acre of pond to cultivate plankton and provide bait for the shrimp fry.

2, stocking

If it is summer stocking, each acre of pond stocking 30,000 to 40,000 baby shrimp, specifications in the 0.8cm or more; if it is autumn stocking, each acre of pond stocking 15,000 shrimp fry, specifications in the 2.5cm or more; if it is winter and spring stocking, each acre of pond stocking 15-20,000 shrimp fry, specifications for the 100-200/kg. 200/kg.

If it is summer stocking, it is usually carried out in the middle and end of July every year; if it is fall stocking, it is usually carried out in the middle of August to September every year; if it is winter and spring stocking, it is usually carried out in December every year or in March to April in the next year. Before stocking, use 4% salt water bath for about 10 minutes.

3, feeding

If it is July to October, the amount of bait for the shrimp about 8 to 12% of the body weight, dry feed or feed according to 2 to 4% co-ordination. Other seasons, the daily bait for shrimp weight of about 2-5%.

If it is July to October, feeding twice a day, of which the evening baiting amount is about 60-70%, if it is other seasons, feeding once a day, the specific feeding time is around sunset every day.

4, management

Oxygen dissolved in more than 5mg / L, water ph control between 7~8.5, water transparency of about 40cm. Every 15-20 days or so, change the water, if it is a high temperature season, every 5-7 days to change the water, each time the amount of water for about 20-30%, and every 15 days or so, every acre of pond using 10-15kg of quicklime water, the whole pond splashing.
