Abstract
The utility model discloses a monolayer floating net cage used for cultivating Gomphina aequilatera, which is provided with a frame (1) with the length of 100-120cm, the width of 60-80cm and the height of 30-40cm, and the frame is made by adopting a reinforcing steel bar with the diameter of 6-8mm; the bottom and the periphery of the frame (1) are encircled by a net piece with the pore diameter of 2-3cm, and the net piece is made of polyethylene; and four horizontally arranged cylindrical buoys (2) which can lead the frame (1) to float are respectively fastened at four corners of upper part of the frame (1) by 6-8 strands of polyethylene ropes (3). The monolayer floating net cage is convenient to manage, check and pick dead aequilatera, and can be ensured to maintain at a stable water layer particularly when the Gomphina aequilatera is close to be mature, so that abortion can not occur due to stimulation; and the monolayer floating net cage is beneficial to cleaning of dead aequilatera and excrement at the tank bottom, has high cultivation survival rate, is convenient for growing-up and stability of the aequilatera, and is an aequilatera cultivation device with good effect, low investment and high success rate.
Description
Technical field:
The utility model relates to the floating type net cage of individual layer that a kind of Bivalve kind shellfish is cultivated usefulness, particularly relates to a kind of equilateral shallow clam kind shellfish and cultivates the floating type net cage of individual layer of usefulness.
Background technology:
Seashells is the important monoid in the marine organisms, also is the important source of protein in people's daily life.Up to the present, existing many scholars carried out research to important halobiontic genetic variation, comprising, important monoids such as fish, oyster, mussel, clam class.Equilateral shallow clam: Gomphina veneriformis (Lamarck) is under the jurisdiction of Mollusca (Mollusca), Bivalvia (Bivalvia), and different tooth subclass (Heterodonta) curtain clam order (Veneridea), popular name is equilateral shallow clam.Bury dwell in the intertidal zone husky to the shallow sea, at the bottom of the husky mud, filter-feeding, its meat is edible, and is delicious, nutritious, shell can be worked as container, is that China has one of economic shellfish of the prospect of propagating artificially.In recent years, because environmental pollution and coyoting such as excessively capture at factor, resource is sharply minimizing.
Kind of shellfish is grow seedlings key of success and basis of equilateral shallow clam, only stores up and plants shellfish, could the output high-quality ripe ovum and active sperm; What could guarantee to grow seedlings carries out smoothly, and therefore respectively the unit of growing seedlings cultivates kind of shellfish and all pays much attention to, and the particularly equilateral shallow clam kind shellfish accelerating of shellfish hatchery is cultivated the main scallop that adopts and formed cylinder mould at present; Form cylinder mould to 8 one 12 layers scallop and load onto back being hung in through bamboo pole such as scallop and cultivate in the nursery pond, shortcoming is a management trouble in cultivating, and checks and to select dead shellfish inconvenient; Particularly when the approaching maturation of kind of shellfish; Inspection kind of shellfish developmental state very easily makes kind of a shellfish be upset when selecting kind of shellfish, causes kind of a shellfish miscarriage; Also be unfavorable for removing ight soil at the bottom of dead shellfish and the pond; It is high that kind of shellfish accelerating is cultivated lethality, is unfavorable for that kind of shellfish is ripe to grow and stable.
Summary of the invention:
The purpose of the utility model provides a kind of equilateral shallow clam kind shellfish and cultivates the floating type net cage of individual layer of usefulness, and it can overcome the above-mentioned shortcoming of prior art, can make that kind of shellfish is in that water quality is good, oxygen is sufficient, grow in the water layer of ambient stable.
A kind of equilateral shallow clam kind shellfish is cultivated the floating type net cage of individual layer of usefulness; It is characterized in that having the framework of the long 100-120cm * wide 60-80cm * high 30-40cm that processes by the reinforcing bar of diameter 6-8mm; Use net sheet that the aperture processes as the polyethylene of 2-3cm with the bottom of this framework and all around, framework upper four limits hitch with 6-8 thigh polyethylene rope respectively can make the cylindrical cursory of four accumbency that this framework floats.
The utility model is convenient to management, checks and selects dead shellfish when using convenient, particularly when kind of shellfish during near maturation, can make it remain on stable water layer, is difficult for being upset causing miscarriage; Help removing ight soil at the bottom of dead shellfish and the pond; It is high that kind of shellfish is cultivated survival rate, is convenient to that kind of shellfish is ripe to be grown and stable, is a kind of effective, small investment, kind shellfish that the success rate of growing seedlings is high stores up device.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Embodiment:
The utility model has the framework 1 of the long 100-120cm * wide 60-80cm * high 30-40cm that processed by the reinforcing bar of diameter 6-8mm; Use net sheet (not drawing among the figure) that the aperture processes as the polyethylene of 2-3cm with the bottom of this framework 1 and all around, four limits, framework 1 top hitch with 6-8 thigh polyethylene rope 3 respectively can make cylindrical cursory 2 of four accumbency that this framework 1 floats.Concrete condition can specifically design its specification according to the size and the shape of nursery pond.
Be placed in the indoor raising of seedling pond when using the utility model, carry out the indoor accelerating of kind of shellfish and cultivate.
Claims (1)
1. an equilateral shallow clam kind shellfish is cultivated the floating type net cage of individual layer of usefulness; It is characterized in that: the framework (1) that the long 100-120cm * wide 60-80cm * high 30-40cm that processed by the reinforcing bar of diameter 6-8mm is arranged; Use net sheet that the aperture processes as the polyethylene of 2-3cm with the bottom of this framework (1) and all around, framework (1) top uses 6-8 thigh polyethylene rope (3) to hitch can to make cylindrical cursory (2) of four accumbency that this framework (1) floats for four jiaos respectively.
