Description
Technical field
The present invention relates to a kind of fresh-water fishes parent population mixed feed, particularly relate to and be a kind ofly applicable to grass carp parent fishes and feeding nutrient health, the environmental protection mixed feed of Tilapia mossambica parent population; Belong to fish meal technical field.
Background technology
Grass carp is one of main large cultured freshwater fish of China, national grass carp cultivation total output about 444.22 ten thousand tons in 2011, national grass carp cultivation total output about 478.17 ten thousand tons in 2012, grass carp cultivation total output about 506.99 ten thousand tons in 2013, within continuous 3 years, cultivation total output amplification is more than 5%, ranks first place.Tilapia mossambica is whole world cultivation one of fingerling the most widely, is the freshwater fish culturing kind that World Aquaculture does emphasis cultivation, is described as animal protein main source.Since 21st century, whole world Tilapia mossambica output increases rapidly, particularly 2004 ~ 2009, whole world output increases to rapidly 3,000,000 tons by 2,000,000 tons, the cultured output of Tilapia mossambica in 2010 reaches more than 340 ten thousand tons, the Tilapia mossambica output in the whole world in 2011 is more than 4,400,000 tons, and wherein cultured output reaches 3,700,000 tons.China's Tilapia mossambica cultured output occupy first place, the world, and account for 39.2% of the total cultured output in the whole world, domestic Tilapia mossambica aquaculture development is rapid, with every year on average 11.1% speed increase.
Grass carp and Tilapia mossambica are China's cultivation, the maximum freshwater fish culturing kind of output, and Tilapia mossambica is mouth hatching property fish, and when water temperature reaches more than 22 DEG C, sexually matured female, milter starts pairing breeding, and embryonated egg enters in raun oral cavity hatches.Grass carp to lay eggs fish for spacious water-based, and when water temperature is more than 22 DEG C, grass carp parent fishes becomes and starts to oestrus pairing, rise impact stimulation under within 1 ~ 2 day, just can lay eggs.In recent years, along with going deep into of China's aquiculture animal genetic breeding research, grass carp, Tilapia mossambica biological engineering reproduction technique reach its maturity.But along with China's culture fishery development, grass carp, Tilapia mossambica seed supply duration, mainly rely at non-time breeding station of laying eggs and use hormone or hormone analogs such as gonadotropin-releasing hormone (GRH), Dopamine D2 receptor etc. to reach the object of hastening parturition.Although be separated with obvious shortening between egg-laying time, Gunther parent fish spawning number of times increases, but this causes parent population endotrophic to be used for greatly sexual cell growth, parent population physique declines, reproductive capacity weakens, egg laying amount and number of times of laying eggs reduces, ovum and sperm quality decline, and rate of fertilization, incubation rate, larva and juvenile survival rate decline, seed resource is degenerated.
Therefore, be necessary that exploitation one can be improved parent population physique, improve its reproductive capacity, thus improve egg laying amount, egg cell and spermatid quality, and then improve the nutrient health of rate of fertilization, incubation rate, larva and juvenile survival rate and quality, the grass carp of environmental protection, the universal mixed feed of Tilapia mossambica parent population.
