Abstract
The invention relates to a large-size-river-crab pond cultivation method. The large-size-river-crab pond cultivation method includes the following steps: constructing pond cultivation conditions; controlling the water quality; constructing the ecological environment; feeding bioactive substances; managing the water quality. The large-size-river-crab pond cultivation method has the advantages that the method is simple, cost is low, the yield of river crabs is high, and the economic benefits are obvious.
Description
Technical field
A kind of river crab ecological pond culture of the present invention method, belongs to technical field of aquaculture, the pond culture of special large gauge river crab.
Background technology
River crab formal name used at school is Eriocheir sinensia, the expensive freshwater product of generic name, because of its lovely luster, fine and tender taste, special taste, nutritious and be described as " top grade in water, banquet delicacies ", and the dark favor by consumers in general.In recent years, drug on the market in river crab market, and price glides to some extent, and especially drop in specification little, inferior river crab price one road, and the large gauge river crab of quality better has occupied advantage in Market Games, and not only in demand, price is also always strong.Therefore, culturist no longer pursues traditional aquaculture model of high density, high investment, high yield, but changes to the ecologic breeding new model of large gauge (female more than 150g, male more than 200g), high-quality, high benefit.This to promotion fishery constitution adjustment, improve crab farming economic benefit and Ecological Effect Yidu significant.Large gauge river crab is cultivated and quality and benefit are taken into account annoying problem and needed us to solve in pond environment.
Summary of the invention
Technical problem to be solved by this invention is to provide one can solve Problems existing in the pond culture of current large gauge river crab, improves the cultural method of river crab specification and quality.
The cultural method that the present invention adopts, comprises the steps:
Pond culture condition builds; Regulating and controlling water quality; The construction of ecological environment; Bioactivator is thrown in; Water quality management.
Further, the technical essential of pond culture condition structure is as follows: the crab pool is built up East and West direction, rectangle (aspect ratio is 1.5:1 or 2:1), the ridge, pool width suitable for reading is no less than 3m, slope ratio is 1: 3, the pool is 1.5 ~ 2.0m deeply, and the depth of water is 1.2 ~ 1.5m, and soil property is that the hard of meta-alkalescence sticks loam.At the circular groove (profundal zone) that surrounding excavation in the pool is 60 ~ 80cm deeply, account for 30% of the pool mouth gross area, by building up cultivation platform (phytal zone) in the middle of the pool, account for 70% of the pool mouth gross area, pool mouth surrounding domatic use 30 object polythene net or polyethylene attach without the close eye net of tying-in.
Further, the technical essential of regulating and controlling water quality is as follows: drain Chi Shui in late November, retains mud 5 ~ 10cm, freezes, shines 15 ~ 20d at the bottom of pond, with the broken bed mud 10cm of rotovator rotary tillage after mud be full of cracks, continues to freeze, shine whole winter;
To water filling 5 ~ 10cm in pond after the beginning of spring, use quicklime or bleaching powder sterilization, consumption is respectively 75 ~ 100kg/667m
2with 10 ~ 15kg/667m
2, after adding aquation slurry, evenly splash in full pond.
Further, the technical essential of the construction of ecological environment is as follows: plant the resurrection type pasture and water such as waterweed, hydrilla verticillata, eel grass and Huang Sicao in the crab pool, take thing as row, between north and south is, line space is 5m × 4m, with 25 ~ 30m for stick, reserves 8 ~ 10m passage between stick, first by waterweed segment (10 ~ 15cm) full pond cuttage afterwards, seeding row spacing is 5m × 6m; Alternately plant hydrilla verticillata, eel grass and Huang grass at the interline of waterweed, make pasture and water coverage rate account for 50% ~ 60% of the full pond gross area.
Further, bioactivator throw in technical essential as follows: throw in three spiral shells, the 1st put 10d in a suitable place to breed inferior to crab kind after throw in, amount is 50 ~ 100kg/667m
2; 2nd throws in before and after clear and bright, and amount is 200 ~ 300kg/667m
2; 3rd threw in inferior to July, and amount is 100 ~ 150kg/667m
2.
Further, the technical essential of water quality management is as follows: one is water level management; Two is add to renew water; Three is quicklime of splashing; Four is use biologic product.
The invention has the beneficial effects as follows: method is simple, with low cost, and output is high, and economic benefit is obvious.
Embodiment
Be described principle of the present invention and feature below in conjunction with example, example, only for explaining the present invention, is not intended to limit scope of the present invention.
