Method for improving fugu obscurus growing characters

Abstract

The invention discloses a method for improving fugu obscurus growing characters and belongs to the technical field of aquatic organism genetic breeding. Three to four aged male and female fugu obscuruses are utilized as parent fishes, and the parent fishes are subjected to domestication and cultivation, artificial induced spawning, insemination, seedling stage cultivation and breeding. The method includes adding 0.01% of a Chinese herbal medicine composed of wild chrysanthemum flowers, mint leaves, dried gingers, largehead atractylodes rhizome, bitter gourd powders and dried orange peels in a bait which is fed in stage of domestication and cultivation, and feeding animal fodders such as lobsters and yellow mealworms 15 days before artificial induced spawning to perform strengthening cultivation. According to the method for improving the fugu obscurus growing characters, the Chinese herbal medicine is added in the bait which is fed in stage of parent fish domestication, the immunologic function of the parent fishes is enhanced, and the qualities of eggs and semens are improved; fertilized eggs are processed by a mixed solution of sodium chloride and potassium chloride, the abhesion effect is uniform and thorough, the fineness and transparency of fertilized egg walls after the abhesion are guaranteed; and the feeding result shows that the culturing cost is substantially reduced, the culturing cycle is shortened by about a half, and the culturing benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of genetic breeding of aquatic organisms, and in particular relates to a method for improving the growth traits of puffer puffer obscurus. Background technique [0002] Fugu obscurus (Takifugu obscurus) belongs to Fuguformes and Fuguidae. It is distributed along the coast and in the middle and lower reaches of the sea. It is commonly known as puffer. Its meat is delicious, and its fat and protein content are high. Its visceral toxins have high medicinal value, and fish skin can be used as leather material. In recent years, the scale of aquaculture has gradually expanded, and Puffer obscurus has become a new and more promising freshwater famous and high-quality cultured species. The artificial breeding of existing puffer puffer, breeding cost is higher, and benefit is low, has limited the development of puffer puffer breeding industry, simultaneously because in existing technology, the viscous fertilized eg...

Problems solved by technology

The artificial breeding of existing puffer puffer, breeding cost is higher, and benefit is low, has limited the development of puffer puffer breeding industry, simultaneously because in existing technology, the viscous fertilized egg hatching of puffer obscurus mostly adopts artificial Fertilized fish eggs are obtained by means of fertilization and artificial squeezing, and debonding is a topic that people pay more attention to. The existing debonding methods usually use mud or talcum powder solution for debonding treatment. The existing debonding methods usually exist Insufficient solution uniformity, uneven debonding, incomplete and other defects, which lead to a significant decrease in the hatching rate of fertilized eggs of puffer pufferfish and an increase in the rate of hatching deformities
