Abstract
The invention discloses a perinereis aibuhitensis accumulated-water-free saturated wet soil cultivation method. The method is characterized by mainly including the following steps of designing a cultivation pond, putting seedlings, controlling the water content and the salt content of soil and casting feed. The key measure is that no water is accumulated in the cultivation pond in the cultivation process and saturated water with the proper salinity is contained in the soil by just spraying water. Compared with an existing cultivation manner, frequent water adding and water discharging are not needed, energy power consumption is relieved, the feed can be conveniently cast, the feed utilization rate is high, the feed cost and pollution to the environment are reduced, the cultivation density is large, the survival rate of perinereis aibuhitensis is high, the growth speed is high, and the cultivation productivity can be higher than 800 kg per mu.
Description
Technical field
The present invention relates to a kind of perinereis aibihitensis Grube without the saturated wet soil cultural method of retaining, belong to technical field of aquaculture.
Background technology
Perinereis aibihitensis Grube (Perinereis aibuhitensis) is under the jurisdiction of Nereidae (Nereididae) in zootaxy, enclose Nereis (Perinereis), be commonly called as extra large centipede, extra large leech etc., mainly be distributed in China, that in more than 80 kind of clam worm of China, individuality is larger, growth is very fast, marine stock biomass maximum a kind of, there is distribution at the middle climax seabeach of China coast from south to north, main representative and the dominant species of intertidal zone Polychaeta ecotype, the main kind that Ye Shi China propagates artificially and exports goods and earns foreign currency.Because it is of many uses in edible, health care, aquaculture and the aspect such as fish, domestic and international market demand is very large, usually occur out of stock in spite of rising price, the situation that supply falls short of demand.
For making up natural resources deficiency, meet the demand of domestic and international market, a lot of places of China coast are carried out one after another it and are propagated artificially in recent years, and its breeding way mainly contains following several at present: 1. the extensive cultivation of beach, rely on natural bait, per mu yield is generally no more than 20 kilograms; 2. raise together with as shrimps with other cultivated animals, the residual bait of the shrimps of take and ight soil are food, and per mu yield is generally no more than 50 kilograms; 3. native pond retaining cultivation, the artitificial food of throwing something and feeding, 15～30d changes water 1 time entirely, because the clam worm process of ingesting is slow, some nutriments in feed of throwing can be dissolved in water, cause nutritive loss, and easily cause water quality and substrate to worsen, the general 300 kilograms of left and right of per mu yield; 4. banket retaining cultivation of cement pit, the artitificial food of throwing something and feeding, changes water every day entirely, the method cultivation self environment is good, and per mu yield generally all surpasses 500 kilograms, and high person even can reach 1000 kilograms, but energy source and power consumption is large, also there is feed nutrition loss, and large to the pollution of culture zone surrounding enviroment.
The present invention utilizes perinereis aibihitensis Grube to move in climax seabeach in intertidal zone, can do on the ebb for a long time the feature of revealing seabeach Survival and growth, the wet soil cultivation perinereis aibihitensis Grube that utilization contains suitable salinity saturation water, the method is due to without retaining, just when for maintenance soil moisture and salinity and bait throwing in, spray a small amount of water, so feed nutrition loss is few, efficiency of feed utilization is high, pollution to breeding environment and surrounding environment is low, do not exist in retaining cultivation and have the rough sledding such as water quality deterioration and anoxic yet, because being exposed in air, soil is also difficult for generating ammonia nitrogen in addition, the harmful substance such as nitrite nitrogen and sulphide, so suitable high-density breeding, cultivation survival rate is high, and clam worm fast growth, the cultured output of unit are is high.
Summary of the invention
The object of the invention is to reduce the aquaculture cost of perinereis aibihitensis Grube, reduce cultivating the pollution of self environment and surrounding enviroment, improve the cultured output of unit are, facilitate aquaculture management.
Technical scheme of the present invention: a kind of perinereis aibihitensis Grube is without the saturated wet soil cultural method of retaining, and the method includes the steps of:
(1) culturing pool design;
(2) seed is thrown in;
(3) soil moisture content and salinity thereof are controlled;
(4) feedstuff feeding.
It is further characterized in that:
The wide 3m of each culturing pool of step (1) left and right, length can not limit, the high 20cm of surrounding embankment left and right, embankment width is suitable to facilitate spray watering and bait throwing in etc. to be operating as, and in pond ploughing depth 20cm left and right, after raking, pour into the sea water immersion that salinity is 22 left and right, soil in culturing pool is fully absorbed water.
Seawater in step (2) venting culturing pool, throws in 35 and has just saved left and right, and body is about the large size seedling seed of 1cm, throws in 600/m of density
2left and right.
Generally not retaining in step (3) breeding process, only need be according to temperature and evaporation discharge shower water every day 1～3 time, makes to contain in soil salinity and be 15～30 saturation water; Stable for guaranteeing the salinity of contained saturation water in soil, shower water used is advisable with fresh water; As also sprayed the seawater that salinity is lower without fresh water, when the salinity of saturation water reaches 30 in soil, in culturing pool, pour into the seawater that salinity is lower, after immersion 30min～120min, discharge again, to take away unnecessary salinity; If because rainfall makes the salinity of contained saturation water in soil lower than 15 o'clock, pour into the seawater that salinity is higher in culturing pool, after immersion 30min～120min, discharge again, to supplement salinity.
Step (4) feed of throwing is powdery compound feed, mix with shower water and evenly spray with water, when the highest water temperature reaches 15 ℃, throw and raise 1 time by body weight 1%～2% every day when the highest temperature, when minimum water temperature reaches more than 15 ℃, throw and raise at twice every day by the amount of body weight 3%～5%, throws something and feeds 2%～3% before darkness, throws something and feeds 1%～2% after daybreak.
Compared with prior art, the present invention has the following advantages:
1, without frequently entering draining, reduced energy source and power consumption;
2, feed mixes sprinkling together with water, throws and raises conveniently evenly;
3, feed nutrition loss is few, and availability is high, has reduced feed cost and the pollution to breeding environment and surrounding enviroment;
4, not retaining in breeding process, do not exist in retaining cultivation and have the rough sledding such as water quality deterioration and anoxic, soil ingress of air is also difficult for generating the harmful substances such as ammonia nitrogen, nitrite nitrogen and sulphide in addition, and cultivation density is high, clam worm survival rate is high, fast growth, and the cultured output of unit are is high.
Embodiment
