Facility for breeding and middle culture of stichopus japonicus seedlings in lagoons and semiclosed gulfs

Abstract

The invention relates to a facility for the breeding and the middle culture of stichopus japonicus seedlings, in particular to a facility for the breeding and the middle culture of stichopus japonicus seedlings in lagoons and semiclosed gulfs. The facility comprises an inner netting, an outer protective net, a plurality of support rods, wind ropes and a plurality of anchor rods, wherein the inner netting is arranged in water by the support rods, and the bottom of the inner netting, connected with the water bottom, is blocked; the outer protective net is arranged on the outer circumference of the inner netting by the support rods, and the support rods for fixing the outer protective net are connected with the support rods for fixing the inner netting by a second rope; and the anchor rods are arranged on the outer circumference of the outer protective net and respectively connected with the support rods for fixing the outer protective net by the wind ropes. The stichopus japonicus seedlings cultured by the facility have strong constitution, thick skin, solid flesh, excellent stress resistance and excellent adaptability to environments and fully have the excellent properties of wild stichopus japonicus. Through the middle culture of the seedlings by the facility, excellent transition environments can be provided to the seedlings to adapt to the wild conditions, and the survival rate of bottom sowing is increased.

Description

technical field [0001] The invention relates to a sea cucumber seed breeding and intermediate cultivation facility, in particular to a sea cucumber seed breeding and intermediate cultivation facility suitable for lagoons and semi-enclosed bays. Background technique [0002] Apostichopus japonicas (Selenka), also known as sea cucumber, belongs to the phylum Echinodermata, class Holothuroidea, family Stichopodidae, genus Apostichopus, and is a typical temperate species. [0003] The economic benefits of sea cucumber farming are huge. In 2010, my country's sea cucumber production reached 130,300 tons, with an annual output value of more than 26 billion yuan. It has become one of the pillar industries of sea cucumber farming in my country, and its development prospects are very broad. [0004] The cultivation of healthy seedlings is one of the cores of the healthy development of the sea cucumber industry. At present, the vast majority of sea cucumber seedlings are cultivated in...

AI Technical Summary

Problems solved by technology

At present, the vast majority of sea cucumber seedlings are cultivated in factories. The high-density artificial environment leads to poor stress resistance of the seedlings, and it is difficult to adapt to growing environments such as ponds, cofferdams, and bays. Uneven etc.
