Abstract
The invention discloses an efficient breeding method suitable for freshwater aquaculture of spanner crabs. The method comprises the specific steps that a breeding pond is built, new water is injected 7-10 days after the breeding pond is disinfected, aquatic plants and strengthening water are put in, then disinfected sterile juvenile spanner crabs are put in, and after the juvenile spanner crabs adapt to the new environment 5-7 days later, feeding can be carried out in batches according to the amount. The breeding method is simple, easy to learn, low in investment cost and reasonable in management, the spanner crabs can survive easily, nutrient substances of water are sufficient, the feeding amount is small, the water environment is good and suitable for growth and development of the spanner crabs, meanwhile, the sick rate of the spanner crabs is reduced, and high benefits are achieved.
Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of efficient cultivation for being suitable to freshwater aquiculture highest-ranking imperial concubine crab
Method.
Background technology
Tiger crab is originally that referred to as " coffee crab " is called highest-ranking imperial concubine crab, and this crab originates from Philippine marine site, Southeast China face mostly
Some waters also produce, because crab lid texture and color are like tiger fur line, so obtaining this alias.Plus the origin of luxuriant and rich with fragrance crab name, because
Its profile and color are similar to the Garfield of cartoon, therefore take its name.
Carapace is in frog shape, and length is more than width, and first half is wider than latter half of.Surface elevation, except frontal region and its neighbouring tool
Outside fur, the squamous projection being directing forwardly of gathering.Cephalolateral margin has the cytofila of two each point of 3 teeth, and lateral margin has serration, after
The sawtooth of half portion forms graininess.The side Mi Gai of carapace becomes mildewed.3 lance tooths of volume point.Eye socket depth, back edge tool 3 is sharp
Tooth, optic stalk is grown up and is stretched out.Pedes tertius is very long narrow, and meropodium surface tool tooth, its top is projected forward.The foot of a chela grows, symmetrical, length
Section leading edge end has a sharp mouth；2 sharp mouths of last green tool of carpopodium；Propodite is flat, and back edge and its end respectively have a sharp mouth, ventral margin tool 5
Individual lance tooth；Two refer to flat, fixed finger inner edge 7-8 lance tooths of tool, movably refer to the back edge tool thorn-like number of teeth piece, its inner rim
About have 5 lance tooths.
And the suitable highest-ranking imperial concubine crab for being easy to freshwater aquiculture is under the jurisdiction of a kind of animal of Decapoda Wa Xing crab section frog crab category, the existing present invention
A kind of high-efficiency breeding method for being suitable to freshwater aquiculture highest-ranking imperial concubine crab is disclosed, exactly for side that highest-ranking imperial concubine crab is adapted to freshwater aquiculture
Method.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of be suitable to efficiently supporting for freshwater aquiculture highest-ranking imperial concubine crab
Grow method.
The technical solution adopted in the present invention is：
A kind of high-efficiency breeding method for being suitable to freshwater aquiculture highest-ranking imperial concubine crab, its method specifically includes following steps：
(1) culturing pool is built, culturing pool is set as ramp type structure, and bottom ramp extends to the culturing pool side water surface, most deep
Place's depth is 1.3-1.6m, and arranges water inlet on one end top of culturing pool, and its other end bottom arranges delivery port, another at its
Side arranges multiple inverted trapezoidal holes, and described hole bottom surface is concordant with pool inner water face, and then culturing pool is carried out disinfection；
(2) new water can be injected to inverted trapezoidal hole by water inlet after culturing pool is sterilized 7-10 days, and is thrown in culturing pool
The pasture and water and culturing pool heelpiece for putting pond gross area 30-40% spread the grains of sand of the thickness for 6-10cm, while per mu puts into dry cow dung just 600-
700kg, urea 20-25kg, can input highest-ranking imperial concubine juvenile crab after the new water injected after 5-7 days is limpid；
(3) amount for putting into highest-ranking imperial concubine juvenile crab is only thrown in by every mu of 2000-2200, and highest-ranking imperial concubine juvenile crab need to be in highest-ranking imperial concubine juvenile crab before input
2-4h is stood in transport case, and salt is added by the weight of water in transport case, it is 2-4% salt to make water be contained within weight fraction, separately
The freshwater mussel and river snail of outer per mu of input 20-30kg；
(4) highest-ranking imperial concubine juvenile crab is put into and carry out after 5-7 days in culturing pool the feeding that feeds intake, day inventory for highest-ranking imperial concubine's juvenile crab gross weight 1-
3%, a point 8 a.m. accounts for the 15-20% of day feeding amount, its feeding amount of 3-4 points in afternoon and accounts for the 30- of day feeding amount to 9 points of its feeding amounts
35% and remaining crab material evening 10-11 points feeding feeding；
(5) per carrying out changing water once within 12-15 days, each quantity of exchanged water is the 70-75% of total water body volume to the water body in culturing pool.
Further, it is described that culturing pool is carried out disinfection, it is the slurries of gained after quick lime of being fermented using Chinese medicine liquid, it is described
The preparation process of slurries includes as follows：
(1) realgar 0.05-0.2 parts, tarragon 7-12 parts, cassia bark 15-20 parts, rhizome of cyrtomium 8-14 part, Radix Isatidis 10- are weighed by weight
After 20 parts, adding the water of its 20-30 times of total weight parts is carried out after secondary decoction, and gained merges liquid；
(2) it is agitated into slurries after adding 30-40 parts quick lime to carry out fermentation 5-10 days in liquid is merged.
Further, described disinfection way is：Brushed in the bottom of culturing pool and side wall with roller brush libation at an ancient wedding ceremony slurries
A thin layer.
Beneficial effects of the present invention：The cultural method of the present invention is easy to learn, and input cost is little, rational management, highest-ranking imperial concubine crab
Seedling is easy to survive, and the nutriment foot of water body, and feeding amount is few, and water body environment is excellent, is adapted to growing for highest-ranking imperial concubine juvenile crab, together
When reduce the sick rate of highest-ranking imperial concubine crab, feed materials and save, income is high.
