Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of stichopus japonicus intermediate rearing with feed and preparation method.
The present invention is through strict scientific experiment, and the mensuration by to nutritive indexs such as the required crude protein of stichopus japonicus, crude fat obtains the needed main nutrient composition index of Stichopus japonicus.On this basis, nutritional need and feeding behaviour according to the stichopus japonicus breeding phase, pass through screening again to feedstuff and processing technology, providing a kind of is the feed of basic ingredient with defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex and composite trace element, and the preparation method of this feed.
Concrete prescription is as follows:
Defatted fish flour 11%-15%
Brewer's yeast 12%-16%
Peeling dregs of beans 4%-8%
Algae powder 28%-68%
B B-complex 0.3%-0.7%
Composite trace element 0.3%-0.7%
Above-mentioned algae powder comprises mouse tail algae powder and sargassum powder and some other algae powder, but better with mouse tail algae powder and sargassum powder, is main filling component.If other component ratio changes, can adjust by the increase and decrease of algae powder.Consider natural food of stichopus japonicus and making full use of of resource, also available sea-tangle powder and the alternative algae powder of ooze of coming unstuck, the sea-tangle powder that wherein comes unstuck accounts for the 9%-16% of total amount, and ooze can account for the 20%-22% of total amount.In addition, for keeping the good of stichopus japonicus enteron aisle and cultivation water environment, can add 0.5% probiotics or the zeolite powder of 4%-5%.
Preparation method of the present invention is as follows: determine that with above-mentioned each good component drops into mixer, mix, put into micronizer then, be ground into 130 orders to 200 purpose mash feeds, pack.
Product of the present invention can be dissolved with seawater by the 1%-5% that deposits pond weight every day during use, in the cultivation pond of evenly splashing after stirring evenly into.
The specific embodiment
Stichopus japonicus feed by the present invention's preparation experiment showed, that through feeding stichopus japonicus grows, and fast growth is raised fast 1.5-2.0 doubly than traditional algae powder, has shortened the time of stichopus japonicus intermediate rearing, has improved the production efficiency of apostichopus japonicus culture greatly.
Embodiment 1
Key component of the present invention comprises defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex and composite trace element, and wherein defatted fish flour accounts for weight ratio 13%, peeling dregs of beans 6%, brewer's yeast 14%, mouse tail algae powder 66%, B B-complex 0.5%, composite trace element 0.5%.Described defatted fish flour is commercially available quality product, and crude protein content is more than 64%, and the peeling dregs of beans contains crude protein more than 46%, and brewer's yeast and mouse tail algae powder are commercially available quality product.That B B-complex adopts is commercially available " six and board " aquatic products B B-complex; That composite trace element adopts is commercially available " six and board " aquatic products composite trace element.
Embodiment 2
Part mouse tail algae among the embodiment 1 is replaced sargassum, replace mouse tail algae powder as sargassum powder with 33%, then the present invention includes defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex and composite trace element, wherein defatted fish flour accounts for weight ratio 12%, peeling dregs of beans 7%, brewer's yeast 14%, mouse tail algae powder 33%, sargassum powder 33%, B B-complex 0.6%, composite trace element 0.4%.Described sargassum powder is commercially available quality product.
Embodiment 3
For making full use of resource, reduce cost, part algae powder is substituted with come unstuck sea-tangle powder and ooze.Then the present invention includes defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex and composite trace element, wherein defatted fish flour accounts for weight ratio 14%, peeling dregs of beans 6%, brewer's yeast 13%, mouse tail algae powder 17%, sargassum powder 13%, sea-tangle powder 16% comes unstuck, ooze 20%, B B-complex 0.6%, composite trace element 0.4%.
Embodiment 4
For keeping the stable of cultivation water, add 5% zeolite powder, then the present invention includes defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex and composite trace element, wherein defatted fish flour accounts for weight ratio 15%, peeling dregs of beans 7%, brewer's yeast 13%, mouse tail algae powder 16%, sargassum powder 12%, the sea-tangle powder 9% that comes unstuck, ooze 22%, B B-complex 0.5%, composite trace element 0.5%, zeolite powder 5%.Described zeolite powder is commercially available quality product.
Embodiment 5
For better keeping the stable of cultivation water, in the foregoing description 4, add on the 4% zeolite powder basis and add 0.5% probiotics again.Then the present invention includes defatted fish flour, peeling dregs of beans, brewer's yeast, algae powder, B B-complex, composite trace element, zeolite powder and probiotics, wherein defatted fish flour accounts for weight ratio 13%, peeling dregs of beans 6%, brewer's yeast 14%, mouse tail algae powder 16%, sargassum powder 14%, the sea-tangle powder 11.5% that comes unstuck, ooze 20%, B B-complex 0.5%, composite trace element 0.5%, zeolite powder 4% and probiotics 0.5%.Described probiotics is six and board " source health treasured ", and this is a kind of probiotics of being made up of profitable strains such as bacillus subtilises.
