By the use of the mixing method, lobsters can be cultured in northwest areas; and water pool utilization rate can be improved.

Description

A kind of cray, loach mixed cultivation method

Technical field

The present invention relates to raising fish and shrimp field, and in particular to a kind of cray, loach mixed cultivation method.

Background technology

Known fishes and shrimps all live in the waters such as rivers, Hu Hai, pond, and the waters such as rivers, pond, ditch are wherein lived in fresh water shrimp more, and its growth, breeding are spontaneous, from numerous.In recent decades, cray fire time various places dining table, because the conventional method for cultivating cray is unsuitable for the Northwest, so the cray of the Northwest is mainly by other places transport.

The content of the invention

In order to solve the above problems, the invention provides a kind of method of the pool cultivated cray of indoor water, to solve the problems, such as the Northwest's cray cultivation.

The method bag A ~ E amounts to 4 steps.

Cultural method described in A needs following cultivation place：Cultivation place water source needs activated carbon to filter；The culturing pool that 1.6 meters × 0.5 meter of plant's reason is constituted, and 1.3 meters of deep positions add separation net in pond, and separation net is provided with the delivery pipe at the top of straight-through culturing pool；0.2 meter of filter water is first filled during preparation cultivation water, is splashed to pool wall and bottom of pond with the Eusol of 10 mg/litre concentration；Transplant in separation net or throw in a number of aqueous plant, account for water capacity 5%-35% and be advisable, juxtaposition mesh sheet, plastic barrel, tile etc., increase cray perch, shell and hidden place；Put and to intake before shrimp deep up to 0.8 meter, intake in water inlet screen filtration, prevent the harmful animals such as insect, small fish and frog's egg from entering in pond；Water temperature is at 24 DEG C～28 DEG C, and water temperature is steady in a long-term；

It is as follows that cultural method juvenile prawn described in B puts step concrete operations in a suitable place to breed：Juvenile prawn breeding density is per the tail of pond 500～800；Action is light during input, dress shrimp instrument submerged is slowly dragged backward juvenile prawn is put in water；Juvenile prawn specification in same pond is consistent substantially, and individual difference can not be too big；

It is as follows that cultural method described in C raises juvenile prawn step concrete operations：Juvenile prawn enters 7 ~ 9 days before pond, feeds and grinds feed, and feed includes Rice ＆ peanut milk, soya-bean milk, and daily feeding volume is about every ten thousand tails juvenile prawn, 0.1 kilogram of bait；Juvenile prawn enters behind pond, feed addition small fish and shrimp, earthworm, spiral shell freshwater mussel meat, fish meal；Throwing amount is the 10% of shrimp body weight；

Cultural method water quality management concrete operations are as follows described in D：During juvenile shrimp cultivation, the dissolved oxygen content in water is maintained at more than 6.9 mg/litres；

The concrete operations that cultural method loach described in E adds are as follows：Treat that juvenile prawn is ripe, it is impossible to after separation net, will clear up in pond, will concentrate on separation net into shrimp, afterwards loach is poured into into bottom of pond cultivation by delivery pipe, loach feed feeds the 85% of original demand two, throws in loach foodstuff and passes through delivery pipe.

This technology can make cray switch to pond cultivation from breed in stew, such that it is able to make the cultivation of cray more flexible, not limited with season by region, while introducing loach, can improve pond utilization rate, while saving loach feed.

Specific embodiment

The present invention says that method comprises the steps：

Cultural method described in A needs following cultivation place：Cultivation place water source needs activated carbon to filter；The culturing pool that 1.6 meters × 0.5 meter of plant's reason is constituted, and 1.3 meters of deep positions add separation net in pond, and separation net is provided with the delivery pipe at the top of straight-through culturing pool；0.2 meter of filter water is first filled during preparation cultivation water, is splashed to pool wall and bottom of pond with the Eusol of 10 mg/litre concentration；Transplant in separation net or throw in a number of aqueous plant, account for water capacity 5%-35% and be advisable, juxtaposition mesh sheet, plastic barrel, tile etc., increase cray perch, shell and hidden place；Put and to intake before shrimp deep up to 0.8 meter, intake in water inlet screen filtration, prevent the harmful animals such as insect, small fish and frog's egg from entering in pond；Water temperature is at 24 DEG C～28 DEG C, and water temperature is steady in a long-term；

It is as follows that cultural method juvenile prawn described in B puts step concrete operations in a suitable place to breed：Juvenile prawn breeding density is per the tail of pond 500～800；Action is light during input, dress shrimp instrument submerged is slowly dragged backward juvenile prawn is put in water；Juvenile prawn specification in same pond is consistent substantially, and individual difference can not be too big；

It is as follows that cultural method described in C raises juvenile prawn step concrete operations：Juvenile prawn enters 7 ~ 9 days before pond, feeds and grinds feed, and feed includes Rice ＆ peanut milk, soya-bean milk, and daily feeding volume is about every ten thousand tails juvenile prawn, 0.1 kilogram of bait；Juvenile prawn enters behind pond, feed addition small fish and shrimp, earthworm, spiral shell freshwater mussel meat, fish meal；Throwing amount is the 10% of shrimp body weight；

Cultural method water quality management concrete operations are as follows described in D：During juvenile shrimp cultivation, the dissolved oxygen content in water is maintained at more than 6.9 mg/litres；

The concrete operations that cultural method loach described in E adds are as follows：Treat that juvenile prawn is ripe, it is impossible to after separation net, will clear up in pond, will concentrate on separation net into shrimp, afterwards loach is poured into into bottom of pond cultivation by delivery pipe, loach feed feeds the 85% of original demand two, throws in loach foodstuff and passes through delivery pipe.
