Method for ecologically breeding lobsters in ponds or paddy fields in high-density manner

Abstract

The invention provides a method for ecologically breeding lobsters in ponds or paddy fields in a high-density manner. The method includes steps of 1, carrying out site selection and construction; 2, setting water inlet and drainage; 3, mounting escape preventive facilities of lobster ponds; 4, arranging required equipment; 5, carrying out disinfection treatment on the lobster ponds; 6, selecting aquatic plants for the lobster ponds; 7, selecting matched aquatic creatures in the lobster ponds; 8, selecting lobster seeds; 9, meeting the water quality requirements; 10, feeding feed; 11, selectingmedicines to be used; 12, managing the lobster ponds; 13, determining finished product capturing time nodes. The method has the advantages that the method is in circulating running water lobster farming modes, stable and diversified ecological breeding environments are established in the paddy fields or the ponds and comprise the aquatic plants, algae and the like, the importance is attached to simultaneous culture on the aquatic plants and phytoplankton, the attention is paid to culture on beneficial bacteria in water bodies, and accordingly the cushion capacity of the water bodies can be improved; the method is simple and feasible, is accurate in operation and applicable to duplication and popularization on diversified scales, and can be easily and effectively managed.

Description

Technical field [0001] The invention relates to the field of freshwater aquaculture, in particular to a method for ecologically high-density breeding of crayfish in a pond or rice field. technical background [0002] At present, China's freshwater aquaculture crayfish industry is developing rapidly. The aquaculture area has exceeded 10 million mu, the output has exceeded 1 million tons, and the total economic output value has exceeded 260 billion yuan. Crayfish aquaculture has become one of the main models of ecological circular agricultural development. However, the development of the freshwater aquaculture crayfish industry still cannot meet the needs of the consumer market. At present, there is still a demand gap of about 1 million tons of crayfish in the domestic market, and the demand in the international market is gradually increasing. The output of freshwater aquaculture crayfish It has become the main factor restricting the expansion of its industry. The domestic average ...

Problems solved by technology

[0003] However, the development of the freshwater cultured crayfish industry is still unable to meet the needs of the consumer market. At present, there is still a demand gap of about 1 million tons for crayfish in the domestic market, and the demand in the international market is also gradually increasing. The output of freshwater cultured crayfish It has become the main factor restricting the expansion of its industry. The domestic average single-season yield per mu is even lower than 150 catties.
