Embodiment 1

[0018] A kind of ecological control method of hippocampus body color in the breeding process, at first build the cement pond with a height of 1.2m, carry out sterilization and disinfection in the cement pond, inject the seawater filtered through 120 mesh screen into the cement pond, the water level of the seawater in the pond is 0.8 ~ 1.0m; the temperature of seawater in the pool is always controlled at 15 ~ 32 °C, and the salinity is always controlled at 15 ~ 35 (weight ‰) (if the temperature is controlled at 26 ~ 30 °C and the salinity is controlled at 20 ~ 30, it is more suitable for the growth of seahorses. Good), after the breeding water body is completed, put the hard algae in the cement pool, and the fresh weight density of the hard algae in the cement pool is 1-2kg / m 3 , and during the seahorse breeding process, the bristle algae always maintain the fresh weight density. When the density exceeds this density, part of the bristle algae should be harvested. About 1 / 3 of t...

Embodiment 2

[0020] An ecological control method for hippocampal body color in the breeding process, which is basically the same as in Example 1, except that sargassum is used instead of hard algae to construct a breeding environment system, and the cultured hippocampus is continuously cultivated for 2 months, and the cultured hippocampus is observed Nearly 60% of them are black, and less than 5% of them are yellow. After about 5 months of breeding, most of them are black seahorses, a small number of individuals are brown, and there are no yellow individuals.

Embodiment 3

[0022] It’s just that there is no breeding environment constructed with macroalgae, that is, cultivating large seahorses in cement ponds without using hard algae or sargassum, and the other culture conditions are the same as in Example 1, and the continuous culture is about 2 months and 5 months, and the culture is observed. The body color of the seahorse is mixed, and the body color of the individual seahorse is about 40% black, 35% brown and 25% yellow.

[0023] The density of one-time stocking in above-mentioned embodiment also can be 150~199 tail / m 3 .

[0024] In the above-mentioned embodiment 1, other green algae such as Ulva, Enteromorpha, etc. can also be used instead of Cleophyte.

[0025] In the above-mentioned embodiment 2, other brown algae such as hijiki etc. can also be used instead of sargassum.

[0026] In the above-mentioned embodiment 1, the hard algae can also be replaced with red algae such as Asparagus, Gracilaria, etc.

[0027] In the above-mentioned e...

Abstract

The invention discloses a method for ecologically regulating and controlling the body colour of a sea horse in the process of cultivation, comprising the construction and the regulation as well as the control of the sea horse, the construction and the regulation as well as the control of cultivation environment, the regulation and the control of cultivation density and time, and the management ofdaily cultivation. In the process of cultivating the sea horse, according to the requirement of the body colour of the object sea horse, the ecological cultivation environment of the sea horse is setup, by putting selected large varech into the ecological cultivation environment, the cultivation environment of the sea horse can be improved, the growth of the sea horse can be promoted, the cultivation growth speed of the sea horse can be accelerated, and survival rate can be significantly improved; and by constructing the background colour and luster of the cultivated sea horse, the body colour of the cultivated sea horse to be adaptive to the change of the colour and the luster can be directionally induced and domesticated, and the colour as well as the luster of the body colour of the sea horse are wholly delightful. Therefore, the invention is the method for ecologically regulating and controlling the body colour of the sea horse in the process of cultivation, thereby having the advantages of high sea horse survival rate, fast growth, whole delightful colour as well as luster and good economic benefit.

Description

technical field [0001] The invention relates to seahorse cultivation, in particular to an ecological control method for hippocampus body color in the cultivation process. Background technique [0002] Seahorses are important small marine bony fishes and are rare marine medicinal animals with high economic value. In recent years, in the European and American markets, seahorses have won the love of the public for their elegant movement, and have become a popular water cluster ornamental name; especially some beautifully colored seahorses, the price is quite high. In the US market, the retail price of a beautiful seahorse can exceed US$100, and an ordinary adult seahorse can cost more than US$30. The beauty of seahorses has a lot to do with their body color. Those with pure and bright body colors are expensive, such as pure yellow, pure red, pure black and other varieties, the price is the highest, and the supply exceeds demand. [0003] At present, there are many ways to cul...
