Composite premixing material for malaber reefcod
Technical field
The invention belongs to the breed fish meal, particularly composite premixing material for malaber reefcod.
Background technology
Grouper is Perciformes (Perciformes), Anabantoidei (Percoidei) Sushi section (Serranidae), the general designation of Epinephelus (Epinephelus) fish, common have an epinephelus akaara (Epinephelus akaara), green hata (E.awoara), malaber reefcod (E.malabaricus), huge grouper (E.tauvina), salmon point grouper (E.fario), saladifish (E.moara), seven band groupers (E.septemfasciatus), salmon shape grouper (E.salmonoides), brown some grouper (E.fuscoguttatus), little tooth grouper (E.microdon), band grouper (E.fasciatus), receive the Soviet Union grouper (E.striatus), epinephelus fuscoguttatus (E.suilhs), perch talc plaques fish (E.laurina) etc., they all have distribution in subtropical zone, the whole world and tropical seas, being important marine fish, also is one of most important seawater cage culture high-level fish of China.Grouper is water warm, have that growth is fast, accommodative ability of environment is strong, culture the survival rate height, anti-high-density rearing, euryhalinous in the lower floor fish, its patient salinity range is 15~45, the 15min of can surviving in fresh water, suitable water temperature is 22~28 ℃.Food ration sharply descends when being lower than 15 ℃.Its feeding habits are wide, but carnivorous partially, happiness food crustacean and other biological bait under the nature.
Malaber reefcod (Epinephelus coioids) is a kind of as grouper, in Fujian, Guangdong, ground such as Taiwan are commonly called as " blue spot ", because its meat is good, growth is fast, be convenient to advantages such as live transport, the important sea-farming new varieties of China's southeastern coast have been become in recent years, but the rarely found report of research of domestic relevant malaber reefcod nutritional need, there are not the feed and the premix of malaber reefcod special use yet, selected feed mostly is seawater fish universal feed, cause culture efficiency not ideal, culture dimension-limited, nutritive disease happens occasionally, if things go on like this, the breed of malaber reefcod certainly will be towards non-health status development.Will as the fixed index of weighing apparatus, filter out the premix compound special that be fit to malaber reefcod growth by feeding experiment with growth rate from the nutrition principle based on this present invention, this then seems particularly important for producing healthy aquatic products.
As everyone knows, in fish culture is produced, the input of bait accounts for more than 50% of aquaculture cost, and premix not only can be played raising immunity of organisms, copingability, improve the aquatic products quality in bait, the prior effect of playing extra-nutrition, regulation and control organism metabolism process, its effect is self-evident.This certainly will play a significant role on status that provides green non-pollution malaber reefcod aquatic products, the sea-farming development of promotion this city and the aquaculture of lifting this city famous-particular-excellent for the city in the whole nation and level.
Summary of the invention
The purpose of this invention is to provide a kind of composite premixing material for malaber reefcod, from the nutrition physiology characteristics of malaber reefcod and the nutritional labeling the muscle, relate to and be fit to its compound premix that grows, composite premixing material for malaber reefcod can be applicable to the industrial aquaculture pattern comprising multivitamin and several mineral materials.
Comprise being fit to its multivitamin that grows and several mineral materials, in conjunction with suitable preparation method, can effectively improve malaber reefcod to the utilization rate of bait, reach and reduce the incidence of disease, reduce feed cost, improve the purpose of output.
The object of the invention technical scheme: malaber reefcod comprises multivitamin and several mineral materials with the composition of premix.
