Abstract
The invention relates to a grouper culturing technology capable of saving grouper culturing bait input, improving culturing benefits and reducing pollution to a water environment, and discloses a high-low nutrition bait repetitive re-feeding-based grouper culturing technology. Adopted high-low nutrition bait repetitive re-feeding comprises high-protein bait-low-protein bait repetitive re-feeding, high-fat bait-low-fat bait repetitive re-feeding, high-decavitamin bait-low-decavitamin bait repetitive re-feeding and high-composite mineral element bait-low-composite mineral element bait repetitive re-feeding, and adopted repetitive re-feeding cycles comprise early and night cycles, a day cycle and a week cycle. According to the technology, the problems of high bait input and low nutrition absorption rate in a conventional grouper culturing process can be effectively solved, pollution and damage to the water environment in a culturing process can be reduced, and the grouper culturing industry can be healthily and sustainably developed.
Description
Technical field
The present invention relates to one and can save Grouper cultivating bait input, improve the Grouper cultivating technology of culture benefit and reduction water body environment pollution.
Background technology
Grouper is the important famous and precious marine fish of China, because of its fast growth, delicious meat, be of high nutritive value and economic benefit large and there are wide market prospects.But current Grouper cultivating all adopts single, that nutrient content is high bait aquaculture model, and bait input is high, Nutrients Absorption rate is low, this aquaculture model not only increases Grouper cultivating bait cost and the pollution to water environment, also easily diseases induced, brings risk to Grouper cultivating.Therefore, the Grouper cultivating technology that research and development can be saved Grouper cultivating bait input, be improved culture benefit, reduce water body environment pollution, becomes the task of top priority.
Summary of the invention
The object of this invention is to provide one and can save Grouper cultivating bait input, improve culture benefit, reduce the Grouper cultivating technology of water body environment pollution, it is high that this technology can solve bait input in current Grouper cultivating process effectively, the problem that Nutrients Absorption rate is low, and to reduce in breeding process the pollution of water body environment and destruction, realize the sustainable health development of Grouper cultivating industry.
Of the present inventionly to circulate the Grouper cultivating technology of throwing something and feeding based on height-low nutrition bait, its height adopted-low nutrition bait circulation is thrown something and fed and is comprised that high protein bait-low-protein bait circulation is thrown something and fed, higher fatty acid bait-low fat bait circulation is thrown something and fed, high B B-complex bait-low B B-complex bait circulation is thrown something and fed, high complex mineral element bait-low complex mineral element bait circulation is thrown something and fed.
The invention described above circulation cycle of throwing something and feeding comprises early, evening circulates, every day circulates and circulates weekly.
During the circulation of described high-protein nutrient bait-low nutrient protein bait is thrown something and fed, contained by high protein bait protein-based in dry weight weight ratio be 45-50, contained by low albumen bait protein-based in dry weight weight ratio be 40-45.
During described higher fatty acid nutrition bait-low fat nutrition bait circulation is thrown something and fed, the contained fat of higher fatty acid bait is 5-10 based on dry weight weight ratio, and the contained fat of low fat bait is 0-5 based on dry weight weight ratio.
During described high B B-complex nutrition bait-low B B-complex nutrition bait circulation is thrown something and fed, contained by high B B-complex bait, B B-complex is 0.5-1 based on dry weight weight ratio, and contained by low B B-complex bait, B B-complex is 0-0.5 based on dry weight weight ratio.
During described high complex mineral element nutrition bait-low complex mineral element nutrition bait circulation is thrown something and fed, contained by high complex mineral element bait, complex mineral element is 0.2-0.5 based on dry weight weight ratio, and contained by low complex mineral element bait, complex mineral element is 0-0.2 based on dry weight weight ratio.
Of the present inventionly to have the following advantages based on height-low nutrition bait Grouper cultivating technology tool of throwing something and feeding that circulates:
1. Grouper cultivating technology of the present invention is carrying out on comprehensive and systematic Research foundation grouper nutritional need and growth behavior and formed, and thus has experiment basis and scientific basis widely, more can meet the nutritional need of grouper.
2. in cultural technique of the present invention, food nutrition element digestibility is high: through digestibility research, grouper is to feed protein digestibility >92%; Total amino acid digestibility >95%; Phosphorus digestibility >75%.
3. cultural technique bait input of the present invention is low: compared with single high nutrition bait of throwing something and feeding, and adopt the technology of the present invention cultivation grouper, bait albumen drops into (by accounting for bait dry weight mass ratio range) and reduces 4-8; Bait fat drops into and reduces 3-6; Bait B B-complex drops into and reduces 0.3-0.7; Bait complex mineral element drops into and reduces 0.1-0.3.
4. in cultural technique of the present invention, Grouper cultivating water body ammonia nitrogen discharge capacity reduces by more than 50%, and heavy metals emission amount reduces by more than 45%.
5. show through Long-term breeding experimental result, raise grouper by the technology of the present invention, fast growth, survival rate is high.
