Description

Method for massively culturing and facility outside a kind of many squama Xi parent populations rooms
Technical field
The present invention relates to method for massively culturing and facility outside a kind of many squama Xi parent populations rooms, belong to the artificial breeding skill of fish Art field.
Background technology
Duo Lin Xi Sillago sihama Forsk á l be under the jurisdiction of Perciformes Perciformes, Anabantoidei Percoidei, Perch Superfamily Percoidea, Xi section Sillaginidae, Xi category Sillago.In Australia, India, Indonesia, Fei Lv Guest and Japan are all distributed, and China's Bohai and Yellow Seas, the East Sea and the coastal waters at the South Sea are also all distributed, and body length is up to 300mm.Many squamas Xi is commonly called as sand borer, ship fourth fish, the wheat head, and the fishing season fished for using spring, season in summer two, as best fishing period, are the important economic fish of China coast, Once considerable position is occupied in China coastal seas fishing operation, but due to overfishing in recent years, individual becomes younger, Colony becomes smallization, and yield is reduced year by year.
Duo Lin Xi finished product fish specifications are small, and aquaculture management is relatively easy to, and cultivation survival rate is high and breeding way is various, economy effect It is beneficial preferable, with very wide industrialization breeding prospect.Patent CN102919186B discloses many squama Xi parents of indoor cement pit Fish breeding method and facility requirements, this method are that cement pit carries out parent fish rearing in the room of workshop, and carry out prenatal nutrition to it Reinforcing and parent population environment conditioning, promote its natural spawning, obtain embryonated egg.But Duo Lin Xi Gunther parent fish spawnings 1 ~ 30,000/tails of amount, enter During professional etiquette modelling artificial breeding, to obtain batch Duo Lin Xi embryonated eggs, parent population demand is up to thousands of tails even tails up to ten thousand, and quantity is huge Big parent population adds cultivation difficulty.And indoor cement pit can only carry out small-scale parent fish rearing, it is impossible to meet scale people Scale parent fish rearing needed for work nursery, and regulating and controlling water quality and disease control are difficult.So far, on being advised outside many squama Xi rooms There is not been reported for the research of modelling cultivation facility and its breeding method.
The content of the invention
It is an object of the invention to provide method for massively culturing and facility outside a kind of many squama Xi parent populations rooms, Application way and set The large-scale cultivation in outdoor carry out Duo Lin Xi parent populations is applied, the batch embryonated egg needed for large-scale artificial nursery can be met, and can Be effectively reduced the generation of disease and regulating and controlling water quality during parent fish rearing with reference to outdoor ecological factor, improve parent population survival rate and The quality of embryonated egg;The breeding method is simple, cultivates facility and is easy to get, it is easy to accomplish Duo Lin Xi outdoor large-scale cultivation, improves Economic benefit.
Technical scheme is as follows:Method for massively culturing outside a kind of many squama Xi parent populations rooms, is following specific steps:
(1)Facility is cultivated to prepare:Deep 1.5 ~ the 1.8m in pond, long 30 ~ 32m are selected, its broadside is semicircle, and semi-circular arc is a length of 8 ~ 10m of ¢ bar shaped raceway pond is as outdoor cultivation pond, and being built along bar shaped raceway pond longitudinal direction in the middle of bar shaped raceway pond has one of length 25m divider wall;Cleaning system, aeration system are equipped with for outdoor cultivation pond, adopt ovum system;
(2)Parent fish rearing:It is sterilized, add water and apply fertilizer, when foundation bait raised growth in pond waters, will select in advance The Duo Lin Xi parent populations selected are placed in bar shaped raceway pond and cultivated, and culture density is 10 tails/m2~ 15 tails/m2
(3)Feeding management:Using Duo Lin Xi special compound feeds, chilled squid meat, oyster meat, clam worm as bait, day bait throwing in Measure as the 5% ~ 8% of fish body weight, feed daily 2 times;Start water purification system, be properly added seawater or change water, keep cultivation water The transparency of body is 50 ~ 60cm;
(4)Collecting fertilized eggs:When cultivating to the egg-laying season, placement, which is adopted ovum system and started, in bar shaped raceway pond adopts ovum system System, collects the embryonated egg for swimming in pond water surface top layer.
It is preferred that, it is described sterilization, add water and fertilising refer to using bleaching powder by per hectare 600kg ~ 900kg consumption to bar Shape raceway pond carries out disinfection, 5 ~ 7 days after sterilization, after toxicity, extracts filtered seawater and includes in bar shaped raceway pond, makes water level 1.5m is reached, then 75 ~ 120kg/ hm are added by area in bar shaped raceway pond2Urea and 7.5 ~ 15kg/ hm2Cross phosphorus Sour calcium carries out the culture of underlying biological bait.
It is preferred that, the water purification system is made up of protein separator or simple water purifier.
It is preferred that, the aeration system is turbine type aerator or paddle aerator.
It is preferred that, the ovum system of adopting is made up of collecting fertilized eggs device and paddle aerator.
It is further preferred that the step(3)During feeding management, Duo Lin Xi special compound feeds are fed usually raising, Chilled squid meat, oyster meat, clam worm are fed before spawning, and by the way of alternately feeding, day feeding volume is the 5 ~ 8% of fish body weight.
Breeding method of the present invention, when carrying out feeding management, daily ration, feeding quantity can be according to weather, water quality and situation of ingesting Appropriate increase and decrease;In Water treatment, it can suitably increase new water, high temperature or low temperature season suitably increase water filling number of times.
Having the beneficial effect that relative to prior art of the invention:Present invention selection bar shaped raceway pond is used as parent fish rearing Pond, and the wall for having long 25m together is built in the middle of bar shaped raceway pond longitudinal direction, using pushing away that turbine type aerator is produced in running Power formation current, circulate along bar shaped raceway pond, are conducive to the collection of embryonated egg;The aeration system used is turbine type Aerator, has both played oxygenation, and thrust is produced again can form current;The simple water purification system used is net by water quality Change device and turbine type aerator composition, will when passing through water purifier by turbine type aerator formation current and generation foam Organic matter discharge culture pond in water body, reaches the effect purified water;What is used adopts ovum system by collecting fertilized eggs device, leaf Wheel type aerator is constituted, and is floated and flowed with current for buoyant egg by the embryonated egg of turbine type aerator formation current and many squama Xi The characteristics of, during by collecting fertilized eggs device, by the effect of ovum collecting of being fertilized.
The present invention can provide suitable condition, rational nutrition arrangement and pipe for the outdoor large-scale cultivation of Duo Lin Xi parent populations The technology of supporting, can meet the batch embryonated egg needed for large-scale artificial nursery, and can be effectively reduced parent with reference to outdoor ecological factor The generation of disease and regulating and controlling water quality in fish cultivating process, improve parent population survival rate and the quality of embryonated egg.
