Embodiment 1

[0027] 1. Pond finishing.

[0028] For the pond, in winter, complete the pond and solidify the ridge to remove excessive silt, and build the ridge to a height of 2m to make it sun and frost. A 0.4m high anti-escape board or fortified escape net is enclosed with asbestos tiles, calcium plastic panels or meshes along the pool ridge to seal the entire aquaculture water body.

[0029] For low-lying ponds and other water bodies, raise pool ridges in winter, and excavate "back", "well" or "field"-shaped deep trenches to make the trench 3m wide and 1.5m deep, and the total area of ​​the deep trenches does not exceed the low-lying pond Half of the total area, and the rest can be leveled. Make it sun frost. A 0.4m high anti-escape board or fortified escape net is enclosed with asbestos tiles, calcium plastic panels or meshes along the pool ridge to seal the entire aquaculture water body.

[0030] Water intake (diversion) 10cm in late March every year, with quicklime 75-100kg / 666m 2 Or use ...

Abstract

The invention relates to a method for culturing finless eel and freshwater crayfish in a pond, which includes (1) selecting pond or low-level pond, or opening ditches such as 'curve', 'well' or 'field' font, keeping sluice above 1.5m in the pond or ditch; (2) clearing and sterilizing the pond, keeping the water depth for 30cm, fertilizing and planting aquatic; (3)the net box of finless eel being an open style, planting water peanut in the box; (4) regulating water quality by stocking silver carp and bighead carp, putting healthy fingerlings of the freshwater crayfish one off in the last decades of April (100kg/666m2), or putting mature fingerlings of the freshwater crayfish whose female and male ratio is 2:1 in the autumn; (5) stocking young finless eels from the last ten-day of April to the first ten-day of May or the last decades of July (1kg/ m2); (6) feeding food per day, the amount of which are 5-8% of the weight of freshwater crayfish; (7)subduing feeds after young finless eels are put in the box and hungry for 3 days, the weight ratio of minced earthworm or fresh fish and finless eel is 5:1, 4:1, 3:1 and 2:1; (8) strengthening water quality management, fertilizing management and prophylaxis osamu work of the aquaculture water and inside the net box.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and specifically relates to a method for breeding rice field eel and Procambarus clarkii in the same pond. Background technique [0002] Monopterus albus and Procambarus clarkii (commonly known as crayfish) are currently in short supply in the domestic and foreign markets. Domestically, there has been an upsurge in farming Monopterus albus and Procambarus clarkii. Many large farming provinces have also set up projects to breed eel and Procambarus clarkii. And research on breeding technology, in order to promote the rapid development of the province's Procambarus clarkii and rice field eel breeding industry. [0003] Studies have shown that the cultivation of Procambarus clarkii is mainly monocultured in ponds or low-lying ponds, supplemented by the cultivation of some silver carp and bighead carp to adjust water quality. In addition, there are reports that the use of monoculture in rice fields or ...
