Seawater greenhouse and method for comprehensive ecological aquaculture by using greenhouse

Abstract

The invention discloses a seawater greenhouse. The length direction of the seawater greenhouse is along the east-west direction, and the north wall is of a brick structure; a double-layer plastic film is arranged at the top of the greenhouse; a heat insulation quilt is laid outside the double-layer plastic film; a stichopus japonicus pool is arranged in the greenhouse; part of the stichopus japonicus pool is located underground, and the underground part accounts for 2/3 of the whole height of the stichopus japonicus pool; meshed reef or stone reef is paved at the bottom of the stichopus japonicus pool; furthermore, the paving area of the meshed reef or stone reef accounts for 40 to 60 percent of the total area of the bottom of the stichopus japonicus pool; a water feeding and drainage pipeline is further arranged on the stichopus japonicus pool; a sea urchin pool is further arranged in the greenhouse; a distance from the bottom of the sea urchin pool to the ground is 1 m; a water feeding and drainage pipeline is further arranged on the sea urchin pool; meanwhile, a submersible pump is further arranged in the stichopus japonicus pool; the tail end of a water drainage pipe of the submersible pump is located in the sea urchin pool; a water drainage pipe which communicates with the stichopus japonicus pool and is provided with a valve is arranged on the sea urchin pool; and a sidewalk distributed along the length direction of the greenhouse is also arranged in the greenhouse. Moreover, the invention further discloses a method for comprehensive ecological aquaculture by using the greenhouse.

Description

technical field [0001] The invention relates to a seawater greenhouse, and also relates to a method for comprehensive ecological breeding of sea cucumbers and sea urchins using the greenhouse. Background technique [0002] Apostichopus japonicus and sea urchin are important species of marine treasures cultured in my country, especially in northern provinces such as Liaoning, Hebei, and Shandong. At present, the culture method of sea cucumber in northern my country is mainly pond culture. In pond culture, the growth period of japonicus is limited to spring and autumn, and summer and winter require aestivation and hibernation respectively. The yield per mu of ponds is basically below 150 kg, and in some areas the yield is less than 75 kg per mu. Therefore, there are problems such as slow growth rate, long breeding cycle and low yield in the pond culture mode of sea cucumber. Sea urchins are mainly cultured in rafts in my country. The current raft farming method has problems...

AI Technical Summary

Problems solved by technology

The current raft culture method has problems such as frequent manual operations such as feeding bait (fresh seaweed), pouring cages, and density, etc. These problems reduce the enthusiasm of fishermen to breed sea urchins

In addition, the main species of cultured sea urchins in my country - sea urchins intermedia is poor in high temperature resistance. In summer, sea urchins cultured in rafts are prone to large-scale death due to high temperature.
