Abstract
The invention relates to a method for cultivating organic green crab. Wherein, its cultivate water meets international standard as year temperature is 7-32Deg. C, salt density is 5-32, and bottom is mud or sand mud. And the invention selects the manual crab seed cultivated at organic cultivation or the natural crab seed; and it mixed cultivates the green crab with at least one of prawn, etc; it at least cultivates 2 times in one year; and the food is fresh natural biology, as acorn barnacle, oyster, etc, while the shelf feed amount is 20-35% of crab weight, and the fish feed amount is 6-12% of crab; and it uses burnt lime, bleaching powder to disinfect the substrate, and uses micro biological agent to improve the water quality.
Description
Technical field
The present invention relates to a kind of aquatic products, especially relate to a kind of method of culturing mud crab according to organic aquaculture principle.
Background technology
Food-safety problem has caused the extensive concern of various circles of society, has become the big crisis of global four outside the population that continues, the resource and environment at present.Along with developing rapidly of Chinese culture fishery, factors such as breeding water body environmental pollution and drug abuse have caused conventional aquatic products quality constantly to descend.Organic aquaculture is as a kind of sustainable development pattern; be intended to realize the coordinated development of healthy and safe breed of aquatic products and ecological environmental protection; be the developing direction and the inexorable trend (Lu Dong of 21 century China's aquatic products healthy aquaculture; Xi Yunguan; Xiao Xingji; Deng. Chinese aquatic product quality safety and organic aquaculture are inquired into. Chinese population resource and environment, 2005,15 (2): 85-88).
Mud crab meat flavour deliciousness, nutritious, growth is fast, strong stress resistance, is good mariculture kind.The blue crab cultivation scale enlarges day by day, has become emerging marine industries of China.Traditional blue crab cultivation is not followed organic aquaculture principle as yet and is carried out, and has problems at aspects such as aquaculture model, bait feeding, disease prevention and cure.Carry out organic blue crab and culture, to keeping the natural flavour mountaineous of mud crab, environmental protection and food security etc. are significant.Do not see the report of organic blue crab cultural method so far as yet.
Summary of the invention
The present invention is intended to provide a kind of cultural method of organic blue crab at the problem of traditional blue crab cultivation in the existence of aspects such as aquaculture model, bait feeding and disease prevention and cure, to promote the sound development of blue crab cultivation industry.
Concrete grammar of the present invention is as follows:
1) culture the place: cultivate water meets 2 class water standards among the GB11607, and water temperature is 7～32 ℃ throughout the year, and seawater salinity 5～32, substrate are silt or husky mud;
2) seed source: select the natural juvenile crab in sea area or follow the artificial juvenile crab that organic aquaculture principle cultivates;
3) aquaculture model: adopt mixed breed,, adopt and put in a suitable place to breed at least 2 times by turns in a year with at least a the raising together with in mud crab and the single varieties such as prawn, grey mullet, the razor clam of hanging, fragrant plant mentioned in ancient texts;
4) bait is thrown in: feed is fresh or fresh and alive natural biological bait, select at least a in barnacle, extra large melon seeds, oyster, blue clam, short tooth clam, spiral shell, cerithium, a species of small clam living in fresh water, the small fish shrimps etc. for use, wherein shellfish (band shell) feeding volume is 20%～35% of a mud crab body weight, and small fish shrimps feeding volume is 6%～12% of a mud crab body weight;
5) disease prevention and cure: use at least a in quicklime, bleaching powder, the tea seed cake etc. substrate to be carried out disinfection, regularly use probiotics improvement water quality during the breed, splashed 1 time in 15～20 days.
Culture the place preferably away from pollution source such as wastewater treatment chemical plant not up to standard, tannery, paper mills, culture the factory site substrate and can utilize existing fish, shrimp, tangleweed pond etc.The best body surface cleaning of the juvenile crab of selecting for use, healthy anosis.When employing was repeatedly put the method for mud crab in a suitable place to breed in 1 year by turns, can begin to put seedling from annual March, cultured through 2～4 months, multiple stocking and multiple fishing, choosing is stayed little greatly.Fresh or the fresh and alive natural biological bait of throwing something and feeding can carry out combination collocation according to the abundance of natural waters biological feed.In disease prevention and cure, forbid to use antibiotic, organic chemistry disinfectant and agricultural chemicals.
The present invention since the breed place of being adopted away from pollution source; with mud crab and prawn; grey mullet; the razor clam of hanging; at least a in the single varieties such as fragrant plant mentioned in ancient texts carries out that single variety is raised together with or many kinds are raised together with; adopt and repeatedly put in a suitable place to breed by turns in 1 year; multiple stocking and multiple fishing; and select fully fresh or fresh and alive barnacle for use; the sea melon seeds; oyster; blue clam; short tooth clam; spiral shell; cerithium; a species of small clam living in fresh water; natural biological bait such as small fish shrimps are as main feed; the control cultivate water has suitable water temperature and salinity, so the present invention is to keeping the natural flavour mountaineous of mud crab; environmental protection and food security have outstanding effect.
