Abstract
The present invention relates to a kind of by reducing the method that salinity promotes ash Hippocampus growth, children Hippocampus regulates salinity during cultivating as follows: before 25 ages in days, control salinity 30 33 ‰；25 40 ages in days, control salinity 15 25 ‰；After 40 ages in days, salinity is controlled 10 20 ‰.The present invention regulates cultivation salinity in different phase to the adaptation ability difference of salinity according to children Hippocampus；Both can ensure the survival rate of children Hippocampus, its rate of growth about 15% can have been improved again, and under the conditions of Low-salinity, form the time about 12 days than shortening under the conditions of normal salinity, thus reduce energy consumption, cost of labor, improve system availability, have a good application prospect.
Description
Technical field
The invention belongs to sea horse cultivation field, particularly to a kind of by reducing the method that salinity promotes ash Hippocampus growth.
Background technology
Hippocampus is tradition rare Chinese medicine.According to statistics, dry product is used as medicine every year more than 200 tons in China.Due to Natural Resources in China
Near exhausted, Hippocampus import most needed for existing market, price raises year by year, and average price has exceeded every kilogram 4000
Unit, according to annual import 200 tons calculating, overbalances 800,000,000 yuan.Owing to Hippocampus natural resources is seriously damaged, for extensive
Multiple resource, many countries have carried out artificial cultivation research in the world.As far back as nineteen fifty-seven, China i.e. carries out sea horse cultivation research,
50 years in the past, though nursery, cultural technique grow a lot, but large-scale production technology does not obtains notable breakthrough yet.At present,
Aquaculture cost height is one of Main Factors limiting Hippocampus scale artificial culture.Therefore, it is badly in need of being carried by improvement cultural technique
High Hippocampus rate of growth, thus reduce aquaculture cost, improve cultivation efficiency.
Summary of the invention
The technical problem to be solved is to provide a kind of by reducing the method that salinity promotes ash Hippocampus growth, the method
Both can ensure the survival rate of children Hippocampus, its rate of growth about 15% can have been improved again, than normal salinity condition under the conditions of Low-salinity
Lower shortening forms the time about 12 days, thus reduces energy consumption, cost of labor, improves system availability, has good application
Prospect.
The present invention's is a kind of by reducing the method that salinity promotes ash Hippocampus growth, and children Hippocampus is adjusted during cultivating as follows
Joint salinity:
Before 25 ages in days, salinity is controlled at 30-33 ‰；
25-40 age in days, controls salinity at 15-25 ‰；
After 40 ages in days, salinity is controlled at 10-20 ‰.
Described 25 age in days Qian Jiyou hippocampus higher primary schools in 3.5 centimetres, 25-40 age in days i.e. children's Hippocampus height 3.5-5.0 centimetre, 40
After age in days, i.e. children's hippocampus is tall and big in 5.0 centimetres.
Described children Hippocampus is during cultivating: water temperature controls at 25-27 DEG C, illumination 1000lux.
Described children Hippocampus is during cultivating: before 15 ages in days, and density holding 3-5 tail/liter；15-25 age in days, density keeps 1-3
Tail/liter；After 25 ages in days, density holding 0.6-1.5 tail/liter.
Described children Hippocampus is during cultivating: Copepods of throwing something and feeding before height 6.5 centimetres, and Copepods density is maintained at 10-15/in the least
Rise；Height 6.5 centimetres-9.5 centimetres, in addition to Copepods, adds the artemia throwing long 0.7-0.9 centimetre of body；After height 9.5 centimetres
Throw something and feed and freeze oppossum shrimp；Day feeding volume is the 10% of Hippocampus body weight.
Beneficial effect
The present invention regulates cultivation salinity in different phase to the adaptation ability difference of salinity according to children Hippocampus；Both children can have been ensured
The survival rate of Hippocampus, can improve again its rate of growth about 15%, forms than shortening under the conditions of normal salinity under the conditions of Low-salinity
About 12 days time, thus reduce energy consumption, cost of labor, improve system availability, have a good application prospect.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that embodiment be merely to illustrate the present invention and need not
In limiting the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, those skilled in the art can
To make various changes or modifications the present invention, these equivalent form of values fall within the model that the application appended claims is limited equally
Enclose.
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
General to be advisable less than 1000 liters.
Two, breeding environment
During ash Hippocampus seedling cultivation, water temperature controls to be preferred at 25-27 DEG C, illumination 1000lux, miniflow water.Children Hippocampus 15 days
Before age, density can keep 5 tails/liter, 15-25 age in days, density can keep 3 tails/liter, after 25 ages in days, density keep 1 tail/liter.
Three, bait feeding
1, children's Hippocampus different phase feeding volume
Children Hippocampus is thrown something and fed Copepods before height 6.5 centimetres, and Copepods density is maintained at 10/milliliter, and height 6.5 centimetres grows to
When 9.5 centimetres, in addition to Copepods, add the artemia throwing body length 0.7 centimetre, with sound rope board before throwing something and feedingHigh unsaturated fatty acid
Strengthen at least 12 hours, artemia day feeding volume be about the 10% of Hippocampus body weight.
2, artemia is thrown something and fed number of times and Feeding time
Children Hippocampus is thrown something and fed Copepods 2 times every day before height 6.5 centimetres, each at 07:30 and 17:00 the most respectively, height 7.5 lis
Rice is when growing to 9.5 centimetres, in addition to the Copepods 2 times of throwing something and feeding, and the artemia 2 times of throwing something and feeding every day, each at 07:30 and 17:00 the most respectively,
Throwing something and feeding after 9.5 centimetres frost oppossum shrimp, siphon every day feces and dead bait 4 times, be 07:00,11:00,14:30 and 18:30 respectively.
Four, salinity regulation and control
1, before 25 ages in days (children hippocampus higher primary school is in 3.5 centimetres), salinity is controlled at 30-33 ‰；
2,25-40 age in days (children's Hippocampus height 3.5-5.0 centimetre), controls salinity at 15-25 ‰ (can be gradually lowered 15 ‰)；
3, after 40 ages in days (children's Hippocampus height about 5.0 centimetres), salinity is controlled at 10-20 ‰ (10 ‰ can be gradually decrease to).
As long as Hippocampus seedling is healthy, according to said method requiring operation, the rate of growth of children Hippocampus is higher than at normal salinity (i.e. 30-33 ‰)
Under the conditions of about 15%.During water temperature 25-27 DEG C, grow to 12 centimetres of average need about 98 days from height 3.5 centimetres, and Hippocampus be healthy and strong,
Survival rate > 90%, and cultivation averagely needs about 110 days under the conditions of 30-33 ‰.
