Abstract

The invention discloses a soilless loach breeding method. A breeding pond is established, a layer of river sand is laid on the pond bottom, a water inlet and outlet pipeline is arranged in the pond, the depth of water in the pond ranges from 30 cm to 60 cm, water hyacinth, ampullariagigas and the like are planted in water, and some planktons are cultivated in water. The soilless loach breeding method has the advantages that loach inhabits in fine sand, the catching efficiency is high during selling, the taste of the loach is better than that of the loach bred in mud, the breeding density is larger than that the loach bred in the mud by four times, and the length of the large loach incubated in spring can reach 15-16 cm at the end of the year in the pond built through concrete.

Description

A kind of loach soilless culture method

Technical field

The present invention relates to a kind of cultivation field, particularly relate to a kind of loach soilless culture method.

Background technology

Loach, body is elongated, and leading portion is slightly cylindrical.Rear portion is flat-sided, belly circle, little.Young, the next, the shape of a hoof.Eye is little, stings under anophthalmia.Palpus 5 is right.Squama is extremely tiny, circular, is embedded in subcutaneous.Body back and both sides grey black, entirety has many little black patchess, and head and each fin also have many black splotches, and the spot on dorsal fin and tail fin film is arranged in rows, and caudal peduncle base portion has an obvious blackspot.There is good nutritive value, by existing cultivation cultural method, often occur loach poor growth, individual little, the meat bilgy odour shortcoming such as heavily.

Summary of the invention

For the problems referred to above, the technical scheme that the present invention takes is:

A kind of loach soilless culture method, is characterized in that: build culturing pool, in pond, low laying one deck river sand, is provided with intake-discharge pipe road, depth of water 30-60cm in pond in pond, and in water, cultivation has weter hyacinth, Pomacea canaliculata etc., cultivates some planktons in water body.

Described culturing pool 50-80 ㎡, the degree of depth is between 80-120cm.

Described after late autumn, build plastic tunnel to culturing pool.Such temperature that can keep cultivation, prevent loach from being freezed to death when passing the winter, due to the lifting of temperature, the growth cycle that can extend loach reaches 4 months, greatly improves the Time To Market of loach.

Described river sand adopts thick river sand and the collocation of thin river sand to use, and the thickness of laying is between 15-25cm.Such energy can improve the living environment of loach, reduces disease to the impact of loach, removes loach bilgy odour with it.

The area coverage of described weter hyacinth at 1/3-2/3, the cultivation density 0.2-0.4kg/ ㎡ of Pomacea canaliculata, weter hyacinth is when summer, loach can be helped to keep the sun off irradiation, and control water temperature, Pomacea canaliculata can digest the excreta of loach, improve water quality, reduce the generation of disease.

The invention has the beneficial effects as follows: because loach fish perches in fine sand, during sale, harvesting efficiency is high, taste is better than raising the loach come in mud, and cultivation density also improves four times than the loach cultivated in mud.In the pond that concrete is made, the loach of hatching in spring, individuality large during the end of the year can grow to 15-16 centimetre.

Embodiment

Embodiment 1

A kind of loach soilless culture method, is characterized in that: build culturing pool, in pond, low laying one deck river sand, is provided with intake-discharge pipe road, depth of water 40cm in pond in pond, and in water, cultivation has weter hyacinth, Pomacea canaliculata etc., cultivates some planktons in water body.

Described culturing pool 50 ㎡, the degree of depth is between 80.

Described river sand adopts thick river sand and the collocation of thin river sand to use, and the thickness of laying is between 15.Such energy can improve the living environment of loach, reduces disease to the impact of loach, removes loach bilgy odour with it.

The area coverage of described weter hyacinth is 1/3, and the cultivation density 0.2kg/ ㎡ of Pomacea canaliculata, weter hyacinth, when summer, can help loach to keep the sun off irradiation, and control water temperature, Pomacea canaliculata can digest the excreta of loach, improves water quality, reduces the generation of disease.

The present invention adopts the advantage of loach soilless culture to be that during sale, harvesting efficiency is high because loach fish perches in fine sand, and taste is better than raising the loach come in mud, and cultivation density also improves four times than the loach cultivated in mud.In the pond that concrete is made, the loach of hatching in spring, individuality large during the end of the year can grow to 15-16 centimetre.

Embodiment 2

A kind of loach soilless culture method, is characterized in that: build culturing pool, in pond, low laying one deck river sand, is provided with intake-discharge pipe road, depth of water 50cm in pond in pond, and in water, cultivation has weter hyacinth, Pomacea canaliculata etc., cultivates some planktons in water body.

Described culturing pool 60 ㎡, the degree of depth is between 100cm.

Described river sand adopts thick river sand and the collocation of thin river sand to use, and the thickness of laying is between 20cm.Such energy can improve the living environment of loach, reduces disease to the impact of loach, removes loach bilgy odour with it.

The area coverage of described weter hyacinth is 2/3, and the cultivation density 0.3kg/ ㎡ of Pomacea canaliculata, weter hyacinth, when summer, can help loach to keep the sun off irradiation, and control water temperature, Pomacea canaliculata can digest the excreta of loach, improves water quality, reduces the generation of disease.

The present invention adopts the advantage of loach soilless culture to be that during sale, harvesting efficiency is high because loach fish perches in fine sand, and taste is better than raising the loach come in mud, and cultivation density also improves four times than the loach cultivated in mud.In the pond that concrete is made, the loach of hatching in spring, individuality large during the end of the year can grow to 15 ~ 16 centimetres.
