Abstract
The utility model belongs to the technical field of artificial culture, and provides a filter device for water changing of a bivalve mollusk culture pond. The technical problem that bivalve mollusk larvas are washed away from a discharge port when a novel water changing method is adopted is solved. The filter device for the water changing of the bivalve mollusk culture pond comprises a box body with a top opening and is characterized in that hollowed openings extending to the middle of the box body from top to bottom are formed in the peripheral side walls of the box body, a filter net bag is arranged in the box body, and the filter net bag is fixed to the tops of the side walls of the box body through top net rings of the filter net bag. The filter device can effectively prevent the bivalve mollusk larvas from being washed away in the water changing process.
Description
Technical field
The utility model belongs to artificial culture technology field, is specifically related to a kind of filter using while changing water for bivalve shellfish culturing pool.
Background technology
In bivalve shellfish larval culture process, cultivating Chi Huanshui is the important component part of routine work, and the quality of changing water effect directly affects growth and the metamorphosis of the young.Current domestic bivalve shellfish young factory culturing all adopts net cage to change water, its concrete operations are that a large net cage is put into and cultivated in pond, then the tube head of drainpipe is put in to the discharge that absorbs water in net cage, after water level drops to a certain degree, to cultivating in pond, send fresh seawater to again.Adopting this mode of operation is mainly to prevent that the bivalve shellfish young from being siphoned away by drainpipe, reaches the effect of water body discharge by the isolation of net cage.But have following point in operating process: 1, net cage volume is large, weight is difficult for greatly moving; 2, in changing water process, must often stir net cage, the young that is attached to box outer surface is washed open, labour is large; 3, to cultivating water in pond, without layering non-selectivity, change water, change water weak effect; 4, net cage manufacturing cost is higher, and processing ease is damaged; 5, in pond, take and change more greatly hydrospace, pond effective rate of utilization is low.The technological deficiency existing in changing water process for solving current bivalve shellfish larval culture pond, a kind of new water method step that changes is cultivated pond gas charging system 5-10 minute for closing, the bivalve shellfish young in pond to be cultivated floats to opening at the middle and upper levels of cultivation pool inner water body and cultivates pond bottom drain control valve later, mass rate of emission is controlled at the 30-40% that emits cultivation pool inner water body in 10-20 minute, then close floss hole control valve, open gas charging system, to cultivating in pond, add fresh seawater to original water level, within interval 10-12 hour, repeat above-mentioned steps.Adopting the above-mentioned water method of changing to change in water process, after closing gas charging system, the weak young of Some Constitution does not have floating in time still in cultivating the middle and lower part in pond, may be run off by floss hole like this in drainage procedure.
Summary of the invention
For preventing from adopting the new-type technical problem that the bivalve shellfish young is run off by floss hole while changing water method, the utility model provides a kind of filter using while changing water for bivalve shellfish culturing pool.
The technical solution adopted in the utility model is: a kind of filter using while changing water for bivalve shellfish culturing pool, this device comprises the casing of an open top, it is characterized in that: described casing surrounding sidewall is provided with the hollow out mouth that is extended downward casing middle part by top, at box house, be provided with the filtration string bag, filter the string bag and by its top net circle, be fixed on the top of wall box.
The filter that the utility model provides can effectively prevent that the bivalve shellfish young is run off in changing water process.
Accompanying drawing explanation
The structural representation of the filter that accompanying drawing 1 is used while changing water for bivalve shellfish culturing pool provided by the utility model.
1, casing, 2, hollow out mouth, 3, the string bag, 4, net circle.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
The concrete structure of this filter as shown in Figure 1, this device comprises the casing 1 of an open top, casing surrounding sidewall is provided with the hollow out mouth 2 that is extended downward casing middle part by top, at box house, be provided with and filter the string bag 3, filter the string bag and by its top net circle 4, be fixed on the top of wall box.During use, the water body that floss hole is discharged enters into the box house of casing middle and lower part by the string bag, part water body is overflowed by the hollow out mouth on wall box, now if any the bivalve shellfish young, enter the string bag, it enters rapidly casing middle and lower part and floats to tank wall direction under the drive of current, after water body exchange, mention the string bag can by net to the bivalve shellfish young return to former pond or minute in its pond.
Claims (1)
1. for bivalve shellfish, cultivate the filter using when water is changed in pond for one kind, this device comprises the casing of an open top, it is characterized in that: described casing surrounding sidewall is provided with the hollow out mouth that is extended downward casing middle part by top, at box house, be provided with the filtration string bag, filter the string bag and by its top net circle, be fixed on the top of wall box.
