Abstract
The invention provides a kind of ichthyophagy crab polyculture method, the method is by the optimization design to processing steps such as inoculation opportunity, condition of culture, the culture speed of snakeheaded fish and river crab has been obviously improved it so that be possibly realized with the mixed breed of river crab by snakeheaded fish, its middle warfare is significantly suppressed.The present invention realizes prominent technique effect with the process of novelty, at the same be easily achieved, cost it is relatively low, therefore with prominent promotion prospect.
Description
Technical field
The present invention relates to technical field of fish culture, and in particular to a kind of ichthyophagy crab polyculture method.
Background technology
Snakeheaded fish, is being commonly called as snakehead, also known as snakeheaded fish, raw fish, wealth fish, snake fish, duration and degree of heating fish etc..Snakeheaded fish natural disposition
Ferociousness, reproductive capacity is strong, and appetite is very big, can often eat up other all fish in certain lake or pond.Snakeheaded fish
Can also on land slide, move to other waters search of food, can be with anhydrobiosis 3 days as long as.River crab is
A kind of large-scale crustacean, the section of body point 21, due to the respectively section mutually healing of head and chest, therefore whole body
It is divided into cephalothorax and the part of belly two.Into crab back side mass colour, carapace 7cm averagely long, 7.5cm wide.River crab
The mud bank of normal live in caves Yu Jiang, river, lakes and marhshes, nocturnalism is food with fish, shrimp, spoil and cereal.
Due to the phenomenon of interspecies competition, above two aquatic animal is difficult to harmonious symbiosis in the prior art.
The content of the invention
It is existing to solve it is contemplated that for the technological deficiency of prior art, there is provided a kind of ichthyophagy crab polyculture method
The slow technical problem of ichthyophagy crab polyculture method culture in technology.
To realize above technical purpose, the present invention uses following technical scheme：
A kind of ichthyophagy crab polyculture method, comprises the following steps：Delivered in pond with every mu of injected volume of 1000 tails
The snakeheaded fish seedling of a length of 3cm of body, 25 DEG C of pond water temperature；When tail counterpoise is less than 10g, size-reduced place is fed
Feed after reason, daily feeding volume is the 5% of pond fish TBW；When tail counterpoise is 10g, it is inoculated with pond
Juvenile river crab, to 18 DEG C, bottom of pond installs the agitating paddle of diameter 2m to adjustment water temperature, and speed of agitator is 20rpm；
When tail weighs 50g, to 22 DEG C, pond depth 1m, adjustment bottom of pond illumination reaches 6000lux, day to adjustment water temperature
Bait throwing in 3 times, each bait throwing in time interval is 3 hours, and daily ration of feeding is the 2% of pond fish TBW.
Preferably, every 10 days change 1 pond water.
Preferably, periodically to release photosynthetic bacteria microbial inoculum in pond.
Preferably, described refers to periodically every 15 days.
Preferably, daily using equipment for increasing oxygen content of water to pond water oxygenation 1.5 hours.
In above technical scheme, the photosynthetic bacteria microbial inoculum is to refer to carry out photoautotrophic microorganism.Should
Method has been obviously improved snakeheaded fish and river crab by the optimization design to processing steps such as inoculation opportunity, condition of culture
Culture speed so that be possibly realized with the mixed breed of river crab by snakeheaded fish, its middle warfare is obtained substantially
Suppress.The present invention realizes prominent technique effect with the process of novelty, at the same be easily achieved, cost
It is relatively low, therefore with prominent promotion prospect.
