Abstract
A multilayer floating net cage for cultivating single body seed oysters is characterized in that a frame with the length of 120-150cm, the width of 60-80cm and the height of 80-100cm is composed of PV pipes with the diameter of 25-30mm. The frame is divided into three layers, the distance between the layers is 25-30cm, and then polyethylene screen cloth is enclosed at the bottom and the periphery to form the net cage with the length of 120-150cm, the width of 60-80cm and the height of 10-15cm. The upper portion of the net cage is open, meshes of the polyethylene screen cloth are determined according to the sizes of the single body seed oysters, the multilayer floating net cage floats in the water by tying floating balls with 10-12 polyethylene ropes, and the layer number of and specifications of the net cage in the specific frame are determined according to the size of a seed oyster pool and the depth of the pool. The single body seed oysters can be directly placed in the net cage, the seed oyster cultivating water body can be fully utilized, the single body seed oysters can be cultivated massively, the seed oysters are fast in growing speed, the survival rate is high, and the net cage is convenient to manage.
Description
Technical field
The utility model relates to a kind of cultchless oyster seedling nursing device, particularly relates to the unsteady net cage of multilayer that a kind of cultchless oyster seedling is cultivated usefulness.
Background technology
Cultchless oyster oyster that is promptly free, no adhesive substrate.Oyster has the life habit of clustering, and normal a plurality of oysters anchor at together, because the restriction of growing space, the hull shape irregular has influenced attractive in appearance widely.Clustering also causes the competition of oyster on food, influences its growth rate.Cultchless oyster does not receive the restriction of growing space owing to its free property, thereby the hull shape rule is attractive in appearance, and size evenly is easy to put in a suitable place to breed and gather in the crops.Cultchless oyster is convenient to breadboard research work, is easy to observe and measure.
The formation of cultchless oyster is when the oyster larva eyespot occurs and promptly has the settlement and metamorphosis ability; It is carried out series of physical and chemical treatment, and making it becomes single free oyster, but the cultivation of cultchless oyster seedling after treatment; Cumbersome; Abroad mainly be to adopt the upwelling device, only be fit to grow seedlings on a small scale production, also be not fit to the apparatus and method of large-scale production at present; Therefore, press for a kind of simple to operate, save labor, the cultchless oyster seedling large-scale production breeding arrangement of ambient stable, convenient management.
Summary of the invention
The purpose of the utility model provides the device that a kind of cultchless oyster seedling is cultivated usefulness, and it can overcome existing cultchless oyster seedling and cultivate the above-mentioned shortcoming that goes up existence.
A kind of cultchless oyster seedling is cultivated the unsteady net cage of multilayer of usefulness; It is characterized in that forming long (120-150) cm * wide (60-80) cm * height (80-100) cm framework by the PV pipe of diameter 25-30mm; Divide 3 layers, distance (25-30) cm between layer and the layer closes (120-150) cm * wide (60-80) cm * height (10-15) the cm net cage of growing up with the polyethylene screen cloth all around with the bottom then; Top is opening; The mesh of polyethylene screen cloth is decided according to the size of cultchless oyster seedling, and the multilayer net cage that floats is to be that ball float floats in the water by 10-12 thigh polyethylene rope, and concrete framework is established the net cage number of plies and decided deeply according to nursery pond size and pond with specification.
The utility model can directly be placed on cultchless oyster on the net cage, can make full use of seedling water, can cultivate the cultchless oyster seedling on a large scale, spat of oyster fast growth, and survival rate is high, is convenient to management.

Accompanying drawing is the structural representation of the utility model.
Embodiment
A kind of cultchless oyster seedling is cultivated the unsteady net cage of multilayer of usefulness; It is characterized in that forming long (120-150) cm * wide (60-80) cm * height (80-100) cm framework 1 by the PV pipe of diameter 25-30mm; Divide 3 layers, distance (25-30) cm between layer and the layer, then with the polyethylene screen cloth with every layer of bottom and growth (120-150) cm * wide (60-80) cm * height (10-15) cm net cage 2 (not marking among the figure) all around; The mesh of polyethylene screen cloth is decided according to the size of cultchless oyster seedling; The multilayer net cage that floats is to be ball float 3 by 10-12 thigh polyethylene rope 4, lets it float in the water, and concrete framework 1 is established the net cage number of plies and decided deeply according to nursery pond size and pond with specification.
The utility model can directly be placed on cultchless oyster on the net cage, can make full use of seedling water, can cultivate the cultchless oyster seedling on a large scale, spat of oyster fast growth, and survival rate is high, is convenient to management.
