Description
Technical field
The invention belongs to aquaculture field, relate to a kind of Eriocheir sinensia (Eriocheirsinensis) and become the indoor water tank in crab stage to form method,
Background technology
Eriocheir sinensia, common name river crab, belongs to typical shellfish, will experience about 20 shells in life, and every shell health increases once.The size of river crab individuality depends on the health growth pattern after shell number of times and each shell, but varying environment condition makes a big impact to increasing after the shell number of times of river crab and shell, and then causes river crab individual difference very large.In addition, after river crab shell in two days, health is soft, if suffer the attack of other biology, can easily cause death.This shell Biological characteristics of river crab, requires in the breeding process of river crab, needs good breeding environment condition and broader breeding water body (as lake, pond etc.).Thus, in current China culture of Chinese mitten crab, be almost outdoor ponds or lake culture entirely.Along with the development to river crab qautobiology and ecological study, need river crab to be carried out to the small size pond such as indoor and carry out culture experiment.Indoor small size pond (as experimental trough etc.) culture of Chinese mitten crab needs to overcome two key issues: one is easily dead in breeding process, and two is that shell number of times is few.And the domestic research and experiment that there is no this respect is reported at present.
Summary of the invention
The present inventor carries out more than 10 years of Eriocheir sinensis technical research, test is formed by the laboratory experiment tank in the one-tenth crab stage of nearly 2 years, achieve very good effect, raising river crab, to carry out normal shell in the experimental tank in laboratory (the same with outdoor breeding pond, can 4-5 shell be carried out), in breeding process, there is not death in most of river crab.Method provided by the invention is the robust techniques grown up in the practice of Eriocheir sinensia laboratory experiment tank breeding production.Can ensure that Eriocheir sinensia has higher survival rate and rate of body weight gain in laboratory experiment tank is formed by this technology.This tests for qautobiology research of river crab and individual growth and provides technological means, by significant to fields such as the breeding of river crab and cultivation.
Therefore, the indoor water tank that the object of this invention is to provide a kind of Eriocheir sinensia forms method.
Technical scheme provided by the invention is: a kind of Eriocheir sinensia laboratory experiment tank forms method, and its step is as follows:
(1) laboratory test tank breeding environment builds: select effective water body volume reach the fiberglass experimental trough of 200L and place veil within it;
(2) crab kind is selected: select the crab kind that specification is close, appendage is sound;
(3) rational breeding density: with every crab, there is 50L water body volume more suitable;
(4) daily management and bait feeding: timing changes water, oxygenation, measurement pH and temperature, food of rationally throwing something and feeding in time; Wherein, pH remains between 7 ~ 8.5, and dissolved oxygen remains on 4mg/L, and temperature is not higher than 30 degrees Celsius;
(5) management during shell: when discovery bait intake reduces, river crab back darkens, and back of the body plastron has slight crack gap, shows that river crab is by shell, does not now change water, does not touch river crab; After shell, take out the old shell sloughed off in time.
Wherein said veil is tile (long 37cm × wide 25cm, pitch of waves 7.5cm, wave height 2.5cm).
The indoor water tank of described Eriocheir sinensia forms method, and before the 2nd shell wherein, granulated meal of throwing something and feeding, after the 2nd shell, increases and to throw something and feed wild fishes, throws something and feeds by the wild fishes shape that is cut into small pieces; Bait throwing in twice every day, sooner or later respectively once.
The indoor water tank of described Eriocheir sinensia forms method, wherein also plants pasture and water in the sink.
The indoor water tank of described Eriocheir sinensia forms method, wherein for management during shell, the soft crab just having sloughed off shell is put into bucket or tank is raised separately, after shell is hardening, puts into tank again.
Tool of the present invention has the following advantages: the present invention is according to Eriocheir sinensis biology and ethology feature, in conjunction with ecologic breeding engineering, forms the one-tenth crab indoor water tank developed for target form method to implement indoor water tank.Through the engineering practice of the present inventor, river crab becomes the indoor water tank of crab to form to achieve successfully, by significant to the field such as breeding and cultivation of river crab.
Embodiment
The specific embodiment of the present invention is as follows:
1, indoor culture facility builds
Select diameter 70cm, the degree of depth is the round fiberglass tank of 70cm, and water body volume is 250L.Also can experimentally Material selec-tion breeding facility, require that preferably effectively water body volume reaches more than 200L.
Putting of veil: owing to dwelling life in the river crab battalion end, liking living in seclusion or living in caves, especially liking there is being the local shell of things concealed.Therefore, in each experimental trough, tile (long 37cm × wide 25cm, pitch of waves 7.5cm, wave height 2.5cm) is put into for covering.
2, crab kind is selected
Crab kind select: neat specification, anosis without wound, appendage perfect, specification with require to select voluntarily according to testing or growing.
3, breeding density
It is more suitable that breeding density has 50L water body volume with every crab.
4, daily management and bait feeding
Daily management: become the crab stage will experience 4-5 shell (reproduction shell) at laboratory experiment tank, good growing environment, agreeable to the taste, appropriate, nutritious feed is very crucial for the degenerate cllipticity ensureing into crab.From crab kind enters experimental trough, will carry out strict control, every day, 15:00-16:00 measured pH (pH remains between 7 ~ 8.5) and dissolved oxygen (more than 4mg/L).Every day, 8:00 and 12:00 measured water temperature, controlled water temperature and did not exceed 30 DEG C.Within every 3 days, change a water (not changing water when shell), each quantity of exchanged water is 50%.
Feedstuff feeding: for front 2 shells, granulated meal of can throwing something and feeding, after the 2nd shell, wild fishes of also should throwing something and feeding, throws something and feeds by the wild fishes shape that is cut into small pieces.Along with the rising of temperature can reduce feeding volume.In order to provide river crab vegetal bait, creating good environment, growth promoting effects, also planting pasture and water (it is main for mainly containing eel grass) in experimental trough, owing to also containing a little spiral shell in earth and pasture and water, this also becomes into the living bait of crab.Bait throwing in twice every day, sooner or later respectively once.
5, management during shell
The growth of river crab and the regeneration of step, always carry out with shell.The river crab health just having sloughed off shell is soft, and can not ingest, resistance is more weak, pay special attention to the management before and after shell.As found, bait intake reduces, and river crab back darkens, and back of the body plastron has slight crack gap, shows that river crab is by shell, does not now change water, does not touch river crab.When river crab shell terminates, the old shell sloughed off should be taken out in time, first soft crab can be put into separately in bucket (or tank) and raise, treat that crab shell is more hardening and be put into again in tank, to avoid cannibalism.
6, effect is formed
2012, that has carried out river crab laboratory experiment tank formed test, achieves and well forms effect, table 1 specific as follows.
Table 1 river crab becomes the laboratory experiment tank of crab to form effect
