Ecological cultivating method for mixed cultivation of sea horses and caulerpa lentillifera

Abstract

The present invention is an ecological culture method for polyculture of hippocampus and long-stem grape fern algae, which comprises the following steps: culture pool preparation: the culture pool is fully cleaned and exposed to the sun and then injected with filtered seawater, the seawater height is 1-1.2m; artificial ecological culture Pond construction: Environmental parameters of breeding pond: water temperature 26±3℃, salinity 32±3‰, PH8±0.2, COD6.8±0.2mg / l, light 6000‑9000lx, transparency 1.3±0.3m, PO 4 3+ ~P1.5±1mg / l, NO 3 + ~N8±2mg / l; polyculture of hippocampus and Botrytis elongatus: when the average body length of the hippocampus is 5cm, they are mixed with selected Botrytis elongatus in the culture pond for polyculture. The present invention constructs a circular ecological breeding system by stocking adult hippocampus and Botrytis elongatus in the breeding pond, so that each ecological niche and trophic level in the breeding pond has suitable breeding objects to adapt to it, avoiding bait waste and pollution.

Description

technical field [0001] The invention relates to the technical field of fern algae culture methods, and more specifically relates to an ecological culture method for the mixed culture of hippocampus and viticola long-stemmed fern algae. Background technique [0002] The seahorse is an important small marine bony fish, which is a first-class protected animal in the world and a second-class national protected animal. It itself has high medicinal value and is known as "Southern Ginseng". Therefore, how to protect the natural resources of seahorses and carry out artificial breeding work is very important. However, seahorses have higher requirements on water quality, water temperature, light intensity and nutritional conditions, especially seahorse larvae have stricter requirements on the breeding environment. And because the seahorses only ingest the bait suspended in the water body, once the bait sinks to the bottom, there will be residual bait, which not only causes the waste...

AI Technical Summary

Problems solved by technology

And because the seahorses only ingest the bait suspended in the water body, once the bait sinks to the bottom, there will be residual bait, which not only causes waste of bait, increases the cost, but also pollutes the water quality with the residual bait, and the death rate of seahorses increases in the long run

At present, seahorse breeding can only solve such problems by increasing the amount and frequency of water changes, which results in high production costs and is not conducive to the promotion of seahorse breeding

[0003] At present, there are many methods for artificially breeding seahorses that have been reported, such as cages, polyester fiber tanks, earthen ponds, cement ponds, and aquariums. The above methods usually require frequent water changes and are labor-intensive.

At present, there is no technology for the polyculture of hippocampus and V. elongatus
