Problems solved by technology

Artificial breeding and release are effective protection measures for fishes that are hindered in reproduction. However, the artificial breeding technology of roundmouth copperfish is still immature, especially the breeding of parents is still difficult. The level of artificial breeding of copperfish is of great significance
[0005] There are currently no gonad-promoting additives for Procambarus clarkii and copperfish

Abstract

The invention belongs to the technical field of aquatic animal culture, breeding physiological regulation and control and disease prevention and control, and discloses a gonad development promoting additive for fishing. The gonad development promoting additive for fishing is prepared from the following raw materials in parts by weights: 10 to 20 parts of motherwort herb, 8 to 15 parts of herba epimedii, 5 to 10 parts of radix astragali, 3 to 6 parts of Chinese wolfberry fruits, 8 to 15 parts of radix angelicae sinensis, 8 to 15 parts of safflowers and 20 to 30 parts of carriers. The inventionalso discloses a preparation method of the gonad development promoting additive for fishing. The preparation method comprises the following steps of weighing the motherwort herb, the herba epimedii, the radix astragali, the Chinese wolfberry fruits, the radix angelicae sinensis, the safflowers and the carriers; respectively drying and cutting up each raw material; after micro-pulverization, performing full and uniform mixing; and sieving the raw materials through a 300-mesh screen, so as to obtain the gonad development promoting additive for fishing. When the gonad development promoting additive for fishing is added into aquatic animal feed, the related hormone level of the gonad development in serum (lymph) can be effectively improved; the gonad development is promoted; the non-specificity immune function of animals can also be improved; and the animal growth is promoted.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, reproductive physiological regulation, and disease prevention and control, and relates to a fish gonadotropic development additive and its preparation method and application, in particular to a Chinese herbal medicine feed additive for promoting aquatic animal gonad development and its preparation method with application. Background technique [0002] The use of intensive facilities for artificial breeding of aquatic animal seedlings is an important guarantee for the healthy development of the aquaculture industry, and it is also an effective means for the protection of some precious aquatic biological resources. It is an economical and effective way to obtain high-quality fertilized eggs and aquatic seedlings by using scientific methods to strengthen the breeding of parents, promote their gonads to fully mature and spawn naturally. At present, the commonly used aquatic animal go...
