Indoor culture system for safe overwintering of leeches

Abstract

The invention discloses an indoor culture system for safe overwintering of leeches. The indoor culture system comprises a culture workshop, wherein thermostats are arranged in the culture workshop; a plurality of culture boxes are arranged in the culture workshop; each box comprises a box body, a water supply pipeline and a water drainage pipeline are arranged on the box body, an opening is formed in the top surface of the box, a drainage port is formed in the bottom of the box and covered with a fabric screen, a water supply port is formed above the opening and connected with a long pipe arranged over the culture box, a row of water outlets are formed in the long pipe, and the water supply pipeline is connected with a hot water source; each box body further comprises an automatic control system which is used for controlling interruption timing, the water temperature or flow velocity of water supply; a water level balancing device for controlling the water level is further arranged on the water drainage pipeline of each box. With adoption of the indoor culture system for safe overwintering of the leeches, the problems of overwintering difficulty for manual culture of the leeches in China and especially the high cost in the north at present can be solved, and the culture economic benefit is increased.

Description

technical field [0001] The invention relates to leech breeding technology, in particular to an indoor breeding system for safe leeches overwintering. Background technique [0002] Most of the existing artificial breeding and breeding of leeches are carried out in paddy fields and ponds, which is not conducive to the observation and management of leeches. And leech is a temperature-changing animal, lacking the ability to self-regulate body temperature, and its body temperature changes with the change of ambient temperature. Therefore, the growth and development of leeches are directly restricted by the ambient temperature, and their mating, oviposition, and dormant overwintering all need to be carried out at an appropriate temperature. The suitable growth water temperature of leeches is 10-35°C, and the growth is fastest at 25-30°C. When the water temperature is lower than 10°C, they burrow into the bottom of the water or in the soil and stones beside the pool to dormant. W...
