A kind of feed for river crab and preparation method thereof
Technical field
The present invention relates to aquaculture feed field, and in particular to a kind of feed for river crab and preparation method thereof.
Background technology
River crab scientific name Eriocheir sinensis, the expensive freshwater product of generic name, delicious flavour is nutritious, with very high economic valency
Value.River crab also cries " crab " and " eriocheir sinensis ", and the carapace that head and chest are combined into is in square circular, and quality is hard.River crab is
A kind of large-scale crustacean, the section of body points 21, due to the respectively section mutually healing of head and chest, thus whole body be divided into cephalothorax and
The part of belly two.River crab often lives in caves the mud bank of Yu Jiang, river, lakes and marhshes, nocturnalism, with fish, shrimp, spoil and cereal as food,
To the river mouth spawning gone to sea, the hatching of 3~May of Second Year, after developing into young crab, then the meat in river of tracing back is fresh for annual autumn normal migration
It is tender, it is the food simply being loved by the people.
The small fish and fish meal of fresh or freezing are adopted the animal fodder of many crabs in the market for main former more
, there is the shortcomings of destroying the stock of fish and easy polluted source in material, do not meet the eating habit that crab likes molded food product, even if
Directly fed with agricultural product, or substituted using other aquaculture kind feeds, feeding method not science fails according to button crab
Nutritional need raising, as a result the medicine that addition antibiotic, heavy metal etc. are harmful to health used in breeding process makes river crab
Nutritional deficiency, poor growth, disease increase, sex premature ratio is high;Existing crab feed single varieties, trophic structure is uneven
Weighing apparatus, it is easily putrid and deteriorated the shortcomings of.Therefore find that a kind of trophic structure is balanced, palatability is good, not facile hydrolysis not polluted source
The feed of novel green health is highly desirable to.
The content of the invention
For the defect of prior art, it is an object of the invention to provide a kind of feed for river crab and preparation method thereof, the river crab
Feed changes conventional feed making method by addition Chinese herb feed additive, and the good palatability to river crab improves river crab
Immunity, reduces the death rate, increased river crab yield.
