Technology for mixed culture of stichopus japonicus and urechis unicinctus

Abstract

The invention provides a technology for mixed culture of stichopus japonicus and urechis unicinctus, which is characterized in that mixed culture of stichopus japonicus and urechis unicinctus is carried out in the bottom of a seawater culture pond provided with a natural slit substrate, the stocking growth of stichopus japonicus is carried out on the surface of the pond bottom and on the substratum of the pond bottom, and the stocking growth of urechis unicinctus is carried out in the natural slit substrate of the pond bottom. Young stichopus japonicus with different specifications are put into the pond in May to June and October to November every year from the first year in northern area, and young urechis unicinctus are put into the pond in October the next year. Good stichopus japonicus are fished in June and November respectively every year, the fishing specification is 1-15 per 0.5kg, after all of the urechis unicinctus are fished in November and December in the third year and in June in the fourth year, cleaning is carried out, the bottom mug is dug while the pond is cleaned, and all sea worms are obtained. After the pond is cleaned, young urechis unicinctus can be put into the pond again for continuous mixed culture of stichopus japonicus and urechis unicinctus. The technology solves the problem that the benefit of the stichopus japonicus culture pond is lowered, and is suitable for mixed culture of stichopus japonicus and urechis unicinctus.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to the polyculture technology of echinopsis monoringensis. Background technique [0002] Sea cucumber aquaculture is the main aquaculture industry in the northern coastal areas of my country in recent years, and the aquaculture output value continues to increase. There are several types of sea cucumber breeding methods, such as shallow seabed sowing, tidal flat pond farming, hanging cage culture in sea area and indoor greenhouse culture. Among them, tidal flat pond farming is the main way of sea cucumber breeding in my country, with the largest breeding area and the largest breeding output. However, in recent years, affected by factors such as the reduction of tidal flat resources, slow breeding technology innovation, climate and natural disasters, pests and diseases, and a sharp drop in the price of sea cucumbers, ponds Breeding benefits are showing a gradual downward trend. Under this i...
