Ecological and environment-friendly industrial aquaculture method for odontobutis potamophila

Abstract

The invention discloses an ecological and environment-friendly industrial aquaculture method for odontobutis potamophila; the method comprises the steps: (1) site selection; (2) construction of farm rooms and subsidiary rooms; (3) construction of a source water purification system; (4) construction of a sewage circulation treatment system; (5) construction of parental fish and spawning ponds; (6) construction of fish larvae and mature fish ponds; (7) sterilization and disinfection treatment; (8) feed management of parental fishes; (9) feed management of fish larvae and mature fishes; (10) pest control; and (11) catching. The ecological and environment-friendly industrial aquaculture method for odontobutis potamophila has the beneficial effects: the aquaculture method is scientific; the aquaculture quality and the yield can be improved effectively; with adoption of the efficient source water purification system and the sewage circulation treatment system, the source water can be purified effectively, the aquaculture sewage can be treated efficiently and rationally and the sewage is treated completely; and the ecological and environment-friendly industrial aquaculture method has no pollution to the environment and is applicable to large-scale industrial aquaculture.

Description

technical field [0001] The invention relates to the field of cultivating river snakeheads, in particular to an ecological and environment-friendly industrial culture method for river snakeheads. Background technique [0002] River snakeheads are small economic fishes belonging to the order Perciformes, Goby suborders, Gobyidae, and the genus Sandfish. It is a unique species in China. It has tender meat and delicious taste. It has always been loved by people, and its market price has always been high. High or low, supply exceeds demand. At present, the current culture of river snakeheads in China mainly adopts the breeding mode, and the yield per unit area is low. [0003] At present, most of the sand snakeheads on the market are caught in natural waters, and the proportion of artificial breeding is still relatively low. The existing artificial culture methods of sand snakeheads are mainly polyculture in ponds, which is limited by the fact that the artificial breeding techno...

Problems solved by technology

[0003] At present, most of the sand snakeheads on the market are caught in natural waters, and the proportion of artificial breeding is still relatively low. The existing artificial culture methods of sand snakeheads are mainly polyculture in ponds, which is limited by the fact that the artificial breeding technology is not more mature and there are many seedlings. Collected in the wild, the feeding management and disinfection in the breeding process are not perfect. Therefore, the scale of farming is generally small, and it is difficult to guarantee the size and output of fish.

[0004] In addition, in the actual artificial breeding technology, efficient sewage treatment and circulation systems are not adopted, resulting in a large amount of water for breeding. Moreover, the sewage generated by farming is not treated and discharged to pollute the surrounding environment, which is neither ecological nor environmentally friendly. , also increased the cost of farming
