Abstract
The invention discloses a method of prawn and Sillago sihama polyculture in a higher-place pond, and belongs to the technical field of aquaculture. The method subjects the Sillago sihama, a eurythermal and euryhaline omnivorous fish which mainly eats zooplankton, and the prawns to polyculture in the higher-place pond which locates above an intertidal zone on a concrete or mulched side slope, covers 1 to 10 mu, and is provided with an intermediate sewage disposal facility, a seawater treatment facility and an oxygenation facility for performing high-density and high-yield cultivation. By utilizing the feeding habits of the Sillago sihama, the use of the method allows an ecological niche of the food chain in a cultivation system in the middle and later periods of prawn cultivation in the higher-place pond to be filled, balance between microalgae and zooplankton in the cultivation system to be dynamically regulated, water quality control of the higher-place pond to be facilitated, and morbidity of the prawns to be reduced; thus the pond space is efficiently used, and the unit yield and benefit are improved. The method is applicable to the prawn cultivation in the higher-place pond, makes room for large-scale cultivation of the Sillago sihama, and has far-reaching significance for mariculture restructuring.
Description
Technical field
The present invention relates to a kind of prawn and Duo Lin Xi feed coefficient polyculture method, belong to technical field of aquaculture.
Background technology
Duo Lin Xi Sillago sihama Forsk á l is under the jurisdiction of Perciformes Perciformes, Anabantoidei Percoidei, perch Superfamily Percoidea, Xi section Sillaginidae, Xi belong to Sillago.Have distribution in Australia, India, Indonesia, Philippine and Japan, also there is distribution in the coastal waters at China's Bohai and Yellow Seas, the East Sea and the South Sea, and body length can reach 300mm.Duo Lin Xi is commonly called as sand borer, ship fourth fish, the wheat head, the fishing season of fishing for spring, season in summer two for best fishing period, it is the important economic fish of China coast, once in China coastal seas fishing operation, considerable position was occupied, but due to overfishing in recent years, individuality becomes younger, and colony becomes littleization, and output reduces year by year.
Duo Lin Xi finished product fish specification is little, and aquaculture management is comparatively easy, and cultivation survival rate is high and breeding way is various, and better economic benefit, has very wide breeding prospect.Prawn is as the principal item of pond mariculture, a large amount of benthons is there is and the soft or hard degree, color, taste etc. of plankton Duo Lin Xi to feed is less demanding in breeding process, the zooplanktons such as the dead shrimp in edible prawn pond, residual bait, copepoda and cladocera; many squamas Xi and prawn are raised together with and be conducive to pond water quality regulation and control, reduce the prawn incidence of disease, more space, efficiency utilization pond, improve unit output and benefit, Duo Lin Xi and prawn Polyculture highly our research and exploitation.Up to now, there are no the report of raising together with related fields about Duo Lin Xi and prawn.
Summary of the invention
The object of this invention is to provide a kind of Duo Lin Xi and prawn polyculture method, the method can reduce the prawn incidence of disease effectively, reduces prawn culturing risk, improves its fanning economics, and is that the cultivation scale expanding Duo Lin Xi creates conditions.
Technical scheme of the present invention is as follows: a kind of prawn and Duo Lin Xi feed coefficient polyculture method are following steps:
(1) select feed coefficient, after draining the water from the pond, carry out dry disinfection; Described feed coefficient refers to: be positioned at more than intertidal zone, cement or mulch film side slope, and area is 0.07 ~ 0.67 hm
2, the pond of blowdown in the middle of being equipped with, Seawater Treatment and oxygenation facility; Described dry disinfection refers to: after the water in pond drains, and the per hectare quicklime of 225 ~ 450kg carries out disinfection;
(2) retaining, cultivates biological feed; Described retaining refers to: the seawater of decimated filtration, makes water level reach 1.5m; Described cultivation biological feed refers to: the urea of per hectare 15 ~ 30kg, the superphosphate of 1.5 ~ 3.0kg carry out the cultivation of underlying biological bait;
(3) seedling is thrown in; Described seedling is thrown in and is referred to: when in water body during underlying biological bait raised growth, throw in the prawn seedling 75 ~ 3,000,000 tails/hm of 0.8 ~ 1.0cm size
