Powdery feed for promoting gonad development of fugu obscurus

Abstract

The invention discloses a powdery feed for promoting gonad development of fugu obscurus. The powdery feed comprises powdery bait, and is characterized in that Chinese herbal medicines and a vitamin complex mixture based on a ratio A and a ratio B, wherein, the Chinese herbal medicines and the vitamin complex mixture are also powdery. When the powdery feed prepared from the Chinese herbal medicines and the vitamin complex mixture is used for feeding the fugu obscurus, irritation to the fish is small, and meanwhile stable gonad development can be promoted so as to realize sexual maturity one sixth of time in advance relative to a natural state, thus achieving higher gonad development degree and improving laid egg (ejaculate) amount and fertilization rate in the case of artificial propagation.

Description

technical field [0001] The invention relates to a fish feed, in particular to a powder feed for promoting the gonad development of puffer puffer obscura. Background technique [0002] Pufferfish (Fugu), commonly known as puffer fish, bang fish, and Ba fish. In the process of artificial breeding of puffer obscurus, the development of the gonads of the broodstock is generally stimulated artificially, that is, multiple injections of ripening agents (LRH-A) are used to increase the spawning rate, which will cause harm to the broodstock. Very strong acute stress, the promotion of ovarian development is not very stable. In addition, the method of gonadotropic development is to regulate the ecological factors during broodstock breeding, such as reducing light, controlling water temperature, etc. This method takes a long time for gonadotropic development and is more time-consuming, and this method must be carried out in combination with artificial ripening.
