Glossogobius giuris juvenile fish compound feed and preparation method thereof

Abstract

The present invention relates to a fish feed and particularly relates to a glossogobius giuris juvenile fish compound feed. The present invention also relates to a glossogobius giuris juvenile fish compound feed preparation method. The glossogobius giuris juvenile fish compound feed includes the following components in parts by mass: fish meal 17-29 parts, sweet potato vine powder 6-14 parts, green hay powder 7-13 parts, silkworm chrysalis meal 5-12 parts, artemisia capillaris 3-8 parts, lysimachia christinae 2-7 parts, perilla frutescens 2-6 parts, kalimeris indica 3-7 parts, ilex purpurea 2-5 parts, fresh ginger 2-6 parts, toona sinensis 1-5 parts, hibiscus esculentus 1-4 parts, fish oil 2-6 parts, honey 1-4 parts, olive oil 1-4 parts and compound multivitamins 1-4 parts. According to the energy metabolism patterns and nutritional needs of the glossogobius giuris juvenile fish, the present invention provides the glossogobius giuris juvenile fish compound feed to completely replace the fish meal. The glossogobius giuris juvenile fish fed by the compound feed is high in survival rates, low in feed coefficient and high in specific growth rates.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile tongue goby; the invention also relates to a preparation method of the compound feed for juvenile tongue goby. Background technique [0002] The tongue goby belongs to the medium and large species of the family Goby. It is a perennial, solitary, nocturnal, and carnivorous bidirectional migratory fish. It dwells in caves under rocks or rotten trees, hides at daytime and comes out at night, and begins to forage at dusk, mainly feeding on small fish and invertebrates. The body is elongated, the front part is cylindrical, and the caudal peduncle is long and flat. The tip of the head is roughly flat, the snout is long and pointed, and the back of the head is flat and slightly convex. Eyes small, located dorsally, slightly protruding from the back of the head. Two pairs of nostrils close to each other, the anterior nostrils are short tubular, the posterior nostrils are sma...

Problems solved by technology

[0003] At present, during the breeding process of juvenile tongue gobies, due to continuous fertilization and baiting, the remaining feces and residual bait are most likely to damage the water quality, which often causes diseases in juvenile tongue gobies. People are dealing with fish diseases Sometimes, the method of splashing bactericidal disinfectant is often used according to the condition, but the drug will more or less produce side effects or toxicity. Although it can kill pathogenic bacteria on the surface of juvenile tongue gobies and in the water, it often causes water pollution. And long-term use will cause the accumulation of drugs, affecting the health of the body, and then affecting the growth rate of juvenile tongue gobies

Juvenile tongue gobies often suffer from lack of resistance due to insufficient nutrition during their growth process, resulting in various fish diseases, which affect the survival rate of tongue gobies. A compound feed for juvenile gobies that ensures feed quality and is beneficial to the growth and development of juvenile gobies is an urgent problem to be solved in the current aquaculture industry of gobies
