Description
Technical field
The present invention relates to aquatic feeds, especially relate to a kind of lithosporic fry micro-granulated feed and preparation method thereof.
Background technology
Grouper (Epinephelus sp) to dwell fish for water warm reef, and (Perciformes) Sushi section (Serranidae), is distributed widely in China's southeastern coast to be subordinate to Perciformes.Grouper delicious meat, nutritious, having higher edibility and health value, is famous and precious marine economy fish.In recent years along with the success of grouper sapling multiplication technology and the development of cultural technique, grouper has become the important sea-farming kind of China Guangdong, Hainan and ALONG COASTAL FUJIAN.But, the cultivation of current lithosporic fry still relies on natural biological feed, the biological feed holding time is short, quality is unstable, sometimes nutritional imbalance, carry the germs of a disease, cause fry fry quality to decline, resistance decline, and often because biological feed is not enough or asynchronous with nursery need of production in producing, lithosporic fry is cultivated on a large scale and is restricted.And along with the growth of fry, biological feed can not meet the nutritional need of fry, which results in fry rearing survival rate lower.The biological feed price of cultivating fry is general higher, and this has increased the weight of fry rearing cost greatly, has had a strong impact on the sustainable development of grouper industry.Moreover because the nutritional need of grouper hatched fry and large gauge grouper fingerling there are differences, itself survival rate is just lower than large gauge grouper fingerling, and this brings new challenge to the cultivation of particle feed for rockfish fry.Therefore, urgently research and develop a kind of fry feed for lithosporic fry and substitute biological feed, ensure the sustainable development of grouper industry.
Chinese invention patent CN1442078A discloses a kind of particle feed for rockfish fry micro-granulated feed and production technology thereof, this feed based on the microparticle of particle diameter 100 ~ 1000 μm, containing protein sources raw material, fat source raw material, antioxidant and immunopotentiator.This micro-granulated feed can meet the nutritional need of particle feed for rockfish fry, and the water surface has the good time of staying, but only can Some substitute biological feed, and quality and the quantity that still effectively can not solve biological feed are unstable, and the high problem of cost is cultivated in grouper nursery.CN103110012A discloses a kind of grouper without sinking property of fish meal expanded pellet diet and preparation method thereof, this feed in 1000 kilograms containing following substances: dephenolization cottonseed protein 0-15 kilogram, globulin powder 27-30 kilogram, FSPC 265-300 kilogram, rice protein powder 170-210 kilogram, fish molten slurry protein 12 0-140 kilogram, calcium dihydrogen phosphate or potassium dihydrogen phosphate 31-33 kilogram, wheat gluten protein 30 kilograms, wheat flour 220 kilograms, phosphatide oil 20 kilograms, 45 kilograms, fish oil, fish trace element 5 kilograms, betaine 2.5 kilograms, salt 3 kilograms, fish multidimensional 1.75 kilograms, Choline Chloride 1 kilogram, l-cn 1 kilogram, mould inhibitor 1 kilogram, zeolite powder 1.55 jin, antioxidant 0.2 kilogram.This solves the high problem of Grouper cultivating cost without sinking property of fish meal expanded pellet diet, but this grouper without the particle diameter of fish meal buoyancy expanding feed more than 4 millimeters, be only applicable to grouper large size fingerling and adult fish culture, be not suitable for the cultivation of just incubating particle feed for rockfish fry.
