Nutritious components of the feed comprise crude protein, crude fat, sugar, crude fibre, ash, salt, phosphorus, water and the like. The feed has the advantages of increasing the survival rate of macrobrachium rosenbergii, accelerating the growth speed of macrobrachium rosenbergii, fast feeding, high stability, convenient use, little environmental pollution and the like. Therefore, healthy development of the industry of larval macrobrachium rosenbergii production and feeding can be promoted.
Description
Technical field
The present invention relates to aquaculture feed field, be specifically related to a kind of Macrobrachium rosenbergii micro-granulated feed in seedling stage and preparation method thereof.
Background technology
Macrobrachium rosenbergii is under the jurisdiction of Palaemonidae on taxology, pond crayfish belongs to.Belong to together with freshwater shrimp, brown shell shrimp and Hainan pond crayfish of the growth of China fresh water.Originating in south east asia, claim again Malaysian prawn, fresh water prawn, long-armed prawn, money shrimp, is one of worldwide large-scale tropical fresh water shrimp.China introduced Macrobrachium rosenbergii in 1976 foster in Guangdong examination, succeeded, and had now been generalized to cultivation in all parts of the country.This shrimp is individual large, and male body length can reach 40 centimetres, 600 grams of body weight; Long 25 centimetres of female gonosome, 200 grams of body weight.Dressing percentage 51.7%, meat is abundant; Approximate containing protein 20.5%(and prawn), fat 0.48%, belongs to high protein, low fat, high-octane high-quality aquatic products.Because it has, individuality is large, growth is fast, feeding habits are assorted, meat flavour is beautiful, the culture-cycle is short, economic benefit high, thereby becomes the improved seeds that worldwide popularization cultivates.Macrobrachium rosenbergii belongs to the kind in the torrid zone, waters, subtropical zone, and it adapts to be limited to 38 DEG C in water temperature; Under be limited to 16 DEG C, thermophilic is 24～30 DEG C.The life of dwelling at the end of Macrobrachium rosenbergii battalion, likes and dwells in pasture and water clump, and out look for food evening, and the major way of ingesting is with stinging sufficient catching small animal and organic debris.Can do sprint swimming, by 6 pairs of appendages and periproct paddling.Squab shrimp seedling claims Magna zoea larva, is called for short the young, live in the degree of saltiness water of certain salinity, if set fire in pure fresh water, and can be dead.The young becomes after juvenile prawn, lives, until Maturation and spawning in fresh water.Macrobrachium rosenbergii artificial propagation is except the ground such as Guangxi, Shandong adopts natural sea-water, and national most areas all adopts artificial preparation seawater, and emergence rate is higher, and technology is mature on the whole, for the cultivation of Macrobrachium rosenbergii spread lays the foundation.
Macrobrachium rosenbergii belongs to Omnivore.Under Artificial feeding conditions, the squab young is mainly taking the fairy shrimp young as food, and after 4～5 times cast off a skin, individuality is grown up; Can ingest and oppress fragment, fish-egg, yolk etc. and other tiny biological feeds.Juvenile prawn after fresh water treatment is converted into omnivorousness, mainly taking the aquatic insect young, small-sized shell-fish, aquatic worms form and organic debris as food.Along with the development of large-scale cultivation, the production requirement of Macrobrachium rosenbergii seed is improved, biologically active bait, particularly halogen worm, wheel animalcule that tradition is used, owing to being subject to the impact of natural environment, produce unstable.Along with the continuous expansion of shrimp seed production, artificial breeding also constantly increases the demand of bait, biological feed not only can not meet the demand that seed produces far away in output, be subject to the Quality Down of the pollution biological feed of environment simultaneously, do not meet the requirement of the shrimp seedling of production high-quality, just increased fluctuation and risk that Macrobrachium rosenbergii seed produces yet.In addition; the cultivation of biological living bait needs large-scale capital expenditure and takies a large amount of spaces; so that the production cost of living bait is too high; the comparision of production complexity of living bait simultaneously; in order to coordinate a large amount of human input of need of production of Macrobrachium rosenbergii seedling, these are all unfavorable for the large-scale development of Macrobrachium rosenbergii breeding.Some production units, in the time of Macrobrachium rosenbergii artificial breeding, due to still not comprehensive to its nutritional need research, feeding part biological bait simultaneously, supplement yolk, very easily polluted-water, and larva survive ratio is low, and to Macrobrachium rosenbergii, cultivation brings larger economic loss.The seed that above-mentioned factor has all seriously restricted Macrobrachium rosenbergii produces, and has hindered further developing of Macrobrachium rosenbergii aquaculture.
Therefore, a kind of nutritional need that can meet growth in seedling period, water stability is good, easy to use, survival rate is high, fast, the economical and practical open-mouthed bait of growing can development and production out, a key issue that has become restriction Macrobrachium rosenbergii seedling to propagate artificially.
Summary of the invention
