Abstract

The utility model discloses a hatching and young separator of tiger spot cuttlefish embryonated egg, including cultivating pond, hatching cage, float, the gas stone that looses, be provided with the hatching basket of round platform form in hatching the cage, the top edge of hatching basket is equipped with the couple, and the top edge of couple and hatching cage articulates, and the basket limit and the basket end of hatching basket all are equipped with the round hole, and the diameter of round hole is 12 -15mm, so brave spot cuttlefish embryonated egg is just hatched in the upper portion of hatching cage hatching basket, and the young of hatching is swum out of with the round hole at basket end on the basket limit of hatching basket, moves about and hides to the bottom of hatching cage for the young and the embryonated egg separation of hatching do benefit to the timely collection of the young.

Description

The hatching of a kind of tiger spot sepiellae seu sepiae germ cell and germling segregation apparatus
Technical field
This utility model relates to the hatching apparatus of sepiellae seu sepiae, is specifically related to hatching and the germling segregation apparatus of a kind of tiger spot sepiellae seu sepiae germ cell。
Background technology
Tiger spot sepiellae seu sepiae (Sepiapharaonis) be subordinate to Mollusca (Mollusca), Sepiida (Sepioidea), Sepiidae (Sepiidae) Sepia (Sepia)。Owing to it has, food transformation rate is high, be suitable for high-density breeding, premunition is strong, grow the advantages such as fast, is the economic siphonopods of a kind of great development breeding prospect。At present to Sepia breed and cultural technique research mainly golden cuttlefish (S.esculentaHoyle) and Sepiella maindroni (S.maindroni) etc. frequent species, if publication number is the utility model patent of CN203194305U, disclose the device of hatching Sepiella maindroni germ cell, it includes cultivating pond, hatching cage (being made up of framework and nylon mesh sheet), float (be arranged on hatching cage and strengthen buoyancy), gas exhausting stone, crux is that hatching cage bottom portion is provided with retraction cord, being connected to plastic disc in retraction cord, plastic disc is provided with aperture, jagged on aperture;Such germ cell is disperse on plastic disc, solves density during incubating oosperm excessive, the problem of anoxia, and aperture and burr also improve the problem of rupture of membranes simultaneously, improve incubation rate。Tiger spot sepiellae seu sepiae germ cell major diameter is (39.7 ± 1.7) mm, and minor axis is (17.1 ± 1.1) mm, germling total length (10.1 ± 0.5) mm of hatching, trunk width (6.1 ± 0.2) mm, and happiness volt bottom or travelling along bottom;But owing to plastic disc is in bottom, the germling of germ cell and hatching, all on plastic disc, makes the germling of germ cell and hatching mix, separate the germling difficulty of hatching。
Summary of the invention
Technical problem to be solved in the utility model is to provide hatching and the germling segregation apparatus of a kind of tiger spot sepiellae seu sepiae germ cell, and it is higher that it has incubation rate, and the germling concurrently separating hatching is easy to feature。
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: the hatching of a kind of tiger spot sepiellae seu sepiae germ cell and germling segregation apparatus, including cultivating pond, hatching cage, float, gas exhausting stone, round table-like hatching basket it is provided with in described hatching cage, the top edge of described hatching basket is provided with hook, the top edge of described hook and described hatching cage mounts, being designed with circular hole at the bottom of the basket limit of described hatching basket and basket, the diameter of described circular hole is 12-15mm。
Compared with prior art, the utility model has the advantage of the hatching of a kind of tiger spot sepiellae seu sepiae germ cell and germling segregation apparatus, including cultivating pond, hatching cage, float, gas exhausting stone, it is provided with round table-like hatching basket in hatching cage, the top edge of hatching basket is provided with hook, hook and the top edge mounting of hatching cage, be designed with circular hole at the bottom of the basket limit of hatching basket and basket, and the diameter of circular hole is 12-15mm;Such tiger spot sepiellae seu sepiae germ cell is hatching in the top hatching basket of hatching cage just, and the germling of hatching circular hole at the bottom of the basket limit and basket of hatching basket is swum out of, and the bottom to hatching cage is travelling and hides so that the germling of hatching separates with germ cell, is beneficial to the timely collection of germling。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail。
Embodiment 1
The hatching of a kind of tiger spot sepiellae seu sepiae germ cell as depicted and germling segregation apparatus, including cultivating pond 1, hatching cage 2, float 3, gas exhausting stone 4, it is provided with round table-like hatching basket 5 in hatching cage 2, the top edge of hatching basket 5 is provided with hook 6, hook 6 and the top edge mounting hatching cage 2, being designed with circular hole 7 at the bottom of the basket limit of hatching basket 5 and basket, the diameter of the top circular hole 7 on basket limit is 15mm, and Circularhole diameter at the bottom of the bottom on basket limit and basket is all 12-13mm。Sepiellae seu sepiae germ cell is placed in hatching basket, in the travelling process permeable hatching basket edge of the germling just incubated or bottom circular aperture entrance hatching cage, (the first half aperture, basket edge is more than aperture, the latter half, travelling process enters hatching cage at the volt end to be conducive to squid larva), after incubating oosperm, the chorion of residual also can pass through hatching basket and enters hatching cage simultaneously, the rotten main cause being incubating oosperm cultivating process and causing water quality to ruin of chorion, therefore chorion is removed in the process collecting hatching germling, it is ensured that water quality is not contaminated。Hatching process can be thrown in hatching cage hatching germling sepiellae seu sepiae open-mouthed bait in advance, it is ensured that hatching germling sepiellae seu sepiae ingests, and drastically increases the survival rate of germling sepiellae seu sepiae。Hook, removal hatching basket can be untied through hatching after a while, germling sepiellae seu sepiae in hatching cage be put into cultivation pond and carries out cultivating and managing, hatching cage endochorion is poured out simultaneously, by using hatching basket can facilitate germ cell and the separation of germling sepiellae seu sepiae。
Embodiment 2
With embodiment 1 basic simlarity, the diameter of the different simply top circular holes 7 on basket limit is also 12-13mm。
