Problems solved by technology

The disadvantage is that the time for the hormone to act is very short, generally 1-3 days, after which the hormone used will be degraded
If you want to maintain the level of hormones in the fish, you must inject once at certain intervals. Multiple injections will not only waste hormones, but the operation is time-consuming and laborious, and it is easy to cause damage to the parent fish.

Embodiment Construction

[0006] Weigh 100ml of water, 5g of gelatin, 1g of dioconone maleate (DOM) and 0.02g of salmon gonadotropin-releasing hormone analogue (SGnRH-A), dissolve and mix them at a temperature of 50-80°C. When the product temperature drops below 23 degrees, the product becomes semi-solid state.

[0007] When using this product, put it into warm water of 50-80°C, the product can be dissolved into a liquid, keep the dissolved liquid in warm water of 25-30°C, and then inject it into cold water fish (water temperature 20°C) hereinafter) in vivo, the product automatically becomes semi-solid. The semi-solid slow-release material is slowly degraded in the fish body, and at the same time, the coated hormone and dioconone are slowly released to achieve the purpose of maintaining the hormone level in the fish body for a long time. The general release time is 20 days to one month.

[0008] Salmon gonadotropin-releasing hormone analog (SGnRH-A) in the present embodiment can be changed into salmon...

Abstract

A slowly-releasing hormone for cold-water fish contains water, gelatin, gonad stimulating hormone or ganodotropic releasing hormone or leuteiniznig hormone, etc.

Description

technical field [0001] The invention relates to a hormone, in particular to a slow-release hormone for cold-water fish. Background technique [0002] At present, when hormones are used in fish in aquaculture, direct injection is generally used, for example, into the abdominal cavity or muscle of fish. Its disadvantage is that the time for the hormone to act is very short, generally 1-3 days, after which the hormone used will be degraded. If you want to maintain the hormone content level in the fish, you must inject it once at a certain time. Multiple injections not only waste the hormone, the operation is time-consuming and laborious, and it is easy to cause damage to the parent fish. Contents of the invention [0003] The purpose of the present invention is to provide a kind of slow-release hormone for cold-water fish, which can overcome the above-mentioned shortcoming of prior art. [0004] A slow-release hormone for cold-water fish, characterized in that it contains w...
