Abstract
The invention relates to a bait feeding method for farmed hippocampus erectus. During the farming period of the young hippocampus erectus, bait feeding is performed according to the following steps that before the body height of the young hippocampus erectus reaches 6.5 cm, copepods are fed to the young hippocampus erectus, wherein the feeding density is 15-20 pieces per milliliter; after the body height of the young hippocampus erectus reaches 6.5 cm, the copepods continue being fed to the young hippocampus erectus, wherein the feeding density is 15-20 pieces per milliliter; adult brine shrimps are fed to the young hippocampus erectus in an auxiliary mode, and the daily feeding amount accounts for 10 percent -12 percent of the weight of the young hippocampus erectus. According to the growth of the young hippocampus erectus, bait of different specifications is fed, and the two kinds of bait with different specifications and different nutritive values are mixed together for feeding; in this way, the feeding efficiency and feeding quality of the young hippocampus erectus can be guaranteed, and therefore cost of bait for the young hippocampus erectus during the stage of 6.5 cm-9.5 cm of the body length of the young hippocampus erectus is lowered by 50 percent; besides, maturing time can be shortened by about 9 days, so that energy consumption and labor cost are lowered, and the system utilization rate is increased. Accordingly, the bait feeding method has good application prospects.

Background technology
Hippocampus is traditional rare Chinese medicine.According to statistics, China's dry product that is used as medicine every year exceedes 200 tons.Because Natural Resources in China is closely exhausted, the required hippocampus import most of existing market, price raises year by year, and average price has exceeded 4000 yuan every kilogram, according to 200 tons of calculating of annual import, overbalances 800,000,000 yuan.Because hippocampus natural resources is seriously damaged, be to recover resource, many countries have carried out and have propagated research artificially in the world.As far back as nineteen fifty-seven, China carry out hippocampus culture research, and 50 years in the past, though grow seedlings, cultural technique grows a lot, large-scale production technology does not obtain remarkable breakthrough yet.At present, bait cost height is one of Main Factors of restriction hippocampus scale artificial culture.Hippocampus cultivation Early seedling stage (before 6.5 centimetres of heights) generally throw something and feed artemia nauplii or copepoda, change later and throw adult ' Luchung ' insect or freezing oppossum shrimp.Due to the selling at exorbitant prices of halogen worm's ovum, large-scale farming is produced seldom and is used, and uses copepoda more instead and substitutes, and can greatly reduce bait cost.But, because copepoda is too little, generally only use 6.5 centimetres of left and right of height.After 6.5 centimetres of heights, can throw something and feed adult ' Luchung ' insect or freezing oppossum shrimp, but because halogen worm nutritive value is lower, single-throw adult ' Luchung ' insect effect is poor; Though freezing oppossum shrimp effect is better than adult ' Luchung ' insect, because the ingest efficiency of dead bait of hippocampus is lower, easily cause waste, price is higher in addition, also causes bait cost to be difficult to lower.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that cultivates grey hippocampus bait feeding, and the method both can ensure the efficiency of ingesting of young hippocampus, can ensure again the quality of ingesting, thereby reduces the bait cost 50% in 6.5-9.5 centimetre of stage; Also can shorten the approximately 9 days time of forming, thereby reduce energy consumption, cost of labor, improve system availability, have a good application prospect.
A kind of method that cultivates grey hippocampus bait feeding of the present invention, the young hippocampus bait of throwing something and feeding as follows during cultivating:
6.5 centimetres of copepoda of throwing something and feeding before of children hippocampus height, the density of throwing something and feeding is 15-20/milliliter;
After 6.5 centimetres of children's hippocampus heights, continue the copepoda of throwing something and feeding, the density of throwing something and feeding is 15-20/milliliter, and auxiliary throwing adult ' Luchung ' insect, and a day feeding volume is 10～12% of hippocampus body weight; Halogen worm is thrown something and fed 2 times, 8 a.m. and 5 thirty of afternoon respectively once, 50% of day feeding volume of at every turn throwing something and feeding.
The long 0.7-0.9 centimetre of described halogen polypide.
Described young hippocampus is during cultivating: water temperature is controlled at 25-27 DEG C, and salinity is not less than 15 ‰, illumination 1000lux.
Described young hippocampus is during cultivating: density maintenance 0.8-1.0 tail/liter.
beneficial effect
The present invention is according to the young hippocampus growth bait of different size of throwing something and feeding, and two kinds of bait specification differences, the different diet collocation of nutritive value are thrown something and fed together; Both can ensure the efficiency of ingesting of young hippocampus, and can ensure again the quality of ingesting, thereby reduce the bait cost 50% in 6.5-9.5 centimetre of stage; Also can shorten the approximately 9 days time of forming, thereby reduce energy consumption, cost of labor, improve system availability, have a good application prospect.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that embodiment is only not used in and limits the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
One, cultivating system
Ash hippocampus seedling cultivating system is made up of culturing pool, culvert system, gas charging system and temperature-controlling system, culturing pool specification generally be no more than 1000 be upgraded to suitable.
Two, breeding environment
During the cultivation of ash hippocampus seedling, water temperature is controlled at 25-27 DEG C for good, and salinity is not less than 15 ‰, illumination 1000lux, miniflow water.Children's hippocampus density keep 0.8 tail/liter.
Three, bait feeding
1, young hippocampus different phase feeding volume
6.5 centimetres of copepoda of throwing something and feeding before of children hippocampus height, the density of throwing something and feeding is 10/milliliter; After 6.5 centimetres of children's hippocampus heights, continue the copepoda of throwing something and feeding, and the halogen worm of long 0.7-centimetre of auxiliary throwing body, halogen worm throw something and feed before use sound rope board
