A kind of Parent Female of Macrobrachium rosenbergii culture pond

Technical field

The utility model is related to a kind of culture pond, and in particular to a kind of Parent Female of Macrobrachium rosenbergii culture pond, belongs to aquaculture Technical field.

Background technology

Macrobrachium rosenbergii (Macrobra'chiumrosenbergiideman) also known as Malaysian prawn, fresh water are long-armed big Shrimp, is a kind of large-scale fresh water shrimp, originates in Southeast Asia.It is with growth is fast, feeding habits are wide, meat nutrition composition is good and cultivation The advantages of cycle is short.Since the sixties in last century, propagate Macrobrachium rosenbergii artificially and quickly grow, existing country in Southeast Asia and other one It is commonplace that a little areas cultivate this shrimp.China introduced this shrimp from 1976, Guangdong, Guangxi, Hunan, Hubei, Jiangsu, on Sea, Zhejiang Deng Shiduoge provinces, cities and autonomous regions are cultivated, and general per mu yield achieves obvious economy up to 70 kilograms -100 kilograms Benefit.

Under the conditions of propagating artificially, more than 8 centimetres of Macrobrachium rosenbergii body length can be only achieved sexal maturity, meet close shrimp standard, use In shrimp seedling breeding.The cultivation period of Parent Female of Macrobrachium rosenbergii is long, during which need to pass through multiple shell, the close shrimp resistance of firm shell It is very weak, other shrimp attack is highly susceptible to, is crushed or even is consumed, the breeding production to Macrobrachium rosenbergii causes huge damage Lose.

At present, in Parent Female of Macrobrachium rosenbergii cultivating process, generally it is used as masking using attenuating cultivation density and plantation pasture and water The two methods of thing cut one another's throat to reduce close shrimp, the part but both approaches all come with some shortcomings, for example：

1st, the close shrimp of low-density cultivation causes the yield of unit area to decline, and is unfavorable for benefit lifting；

2nd, plantation pasture and water want periodic cleaning to trim, and otherwise pasture and water are rotted the polluted water in culture pond, add manually into This.

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that foregoing heavy mesh sheet (3) is by reinforcing bar housing (31) and first Fishing net (32) is constituted, and the outward flange of the first fishing net (32) is tied up on reinforcing bar housing (31).

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that the aperture of foregoing first fishing net (32) is 1cm-5cm.

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that the angle of inclination of foregoing heavy mesh sheet (3) is 45 degree -60 Degree.

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that aforementioned hollow housing (41) is made of pvc pipe, leads to Glue is crossed to be bonded.

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that stomata (43) on aforementioned hollow housing (41) it is straight Footpath is 2mm-5mm, at intervals of 3cm-5cm.

Foregoing Parent Female of Macrobrachium rosenbergii culture pond, it is characterised in that the distance of foregoing floating mesh sheet (4) to bottom of pond is 30cm- 50cm。

It is of the present utility model to be beneficial in that：Parent Female of Macrobrachium rosenbergii culture pond of the present utility model, using multiple means The environment of suitable close shrimp life has been built, close shrimp has been effectively reduced and cuts one another's throat, need not both reduce cultivation density, be conducive to effect Benefit lifting, need not plant pasture and water, reduce cost of labor, realize the lifting of production efficiency again.
