Ecological circulation culture method and device for algae, prawns and sinonovacula constricta in winter

Abstract

The invention discloses an ecological circulation culture method and device for algae, prawns and sinonovacula constricta in winter. The device comprises an alga pond, a high-position prawn culture pond, settling ponds, a sinonovacula constricta culture pond and purifying ponds, wherein a thermal-insulation plastic shed covers each pond; the high-position prawn culture pond is provided with a boiler. The method includes: inoculating micro-alga seed sources artificially cultured in the alga pond into the high-position prawn culture pond, the optical prawn culture temperature is guaranteed through boiler heat supply, micro-algae in prawn culture water passing the settling ponds is pumped into the sinonovacula constricta culture pond to serve as baits, and micro-alga seawater filtered by sinonovacula constricta is purified by the purifying ponds and pumped into the high-position prawn culture pond for recycling. The ecological circulation culture method and device has the advantages that the sinonovacula constricta can obtain sufficient micro-alga baits and appropriate growth water temperature in the whole culture period, and the high-position prawn culture pond is allowed to keep a relatively-stable water ecological environment system at the same time.

Description

technical field [0001] The present invention relates to a winter algae shrimp razor ecological circulation cultivation method and device, in particular to a winter microalgae, prawns, hanging razor ecological circulation cultivation system, specifically a boiler tower, algae pool, high-level shrimp pond, The sedimentation tank and the razor clam culture pond are connected to give full play to the functions of each ecological niche and energy, thereby ensuring the water quality safety of the high-level shrimp culture pond and the healthy growth of shrimp bodies, and at the same time ensuring that the razor clam can still grow rapidly in winter; the invention belongs to the technical field of aquaculture. Background technique [0002] As one of the four traditional cultured shellfish in my country, razor clam is distributed from Liaoning in the north and Guangdong in the south, and occupies a pivotal position in the shellfish farming industry in my country. Its growth has wide...

AI Technical Summary

Problems solved by technology

However, shrimp farming in high-level ponds is a high-density intensive shrimp farming method, and it is impossible to concentrate microalgae, shrimps, and razor clams in one culture system at the same time; in winter, due to the decrease in water temperature, the fecundity of Thalassiosira wilsonii decreases. It is also impossible to ensure the safety of water quality at all times; in the season when the growth of razor clams is relatively vigorous, after the bait microalgae in the water body are all ingested by shellfish, it is impossible to get timely replenishment

[0006] In order to solve the above deficiencies, the present invention has set up a kind of microalgae, prawn, and razor clam ecological cycle breeding system, so that the bait microalgae culture area, the shrimp culture area in the high-level pond, and the razor clam culture area can be isolated from each other, and can be passed daily. Manage the supply of microalgae provenance to the shrimp culture area in the high-level pool, form the dominant population in the pool, achieve the effect of purifying the water quality, and ensure the healthy growth of the shrimp; on the other hand, use the high-density microalgae bait in the high-level pool and the water body At the same time, it meets the bait and higher temperature required for the rapid growth of razor clams, and solves the problem of low growth rate of razor clams due to insufficient bait and low temperature in winter
