Description
Technical field
The utility model relates to Sepiella maindroni fertilized egg enhancement releasing field, especially relates to a kind of Sepiella maindroni fertilized egg enhancement releasing assembly.
Background technology
Sepiella maindroni (Sepiella maindroni de Rochebrune), be commonly called as inkfish, order fish, be subordinate to Mollusca (Mollusca), Cephalopoda (Cephalopoda), Decapoda (Decapoda), Sepiidae (Sepiidae), sepiella maindroni de Rochebrune genus (Sepiella).Sepiella maindroni is distributed widely in coastal area of china, Russian Far East sea, Japanese Seto Island Sea and the Korea southwest sea area such as coastal, one of " four large marine products " that fishing ground, Zeng Shi China East Sea is traditional.But fish for along with transition for many years, the quantity of Sepiella maindroni significantly reduces, and to the middle and later periods eighties, Along Zhejiang Coast fishing ground Sepiella maindroni cannot form fishing season, and progressively disappeares.In order to repair Sepiella maindroni resource, China aquatic science and technology personnel have carried out the artificial breeding research of Sepiella maindroni.
Enhancement releasing is the effective means increasing the amount of marketable aquatic animals which can be caught to supplement fishery resources, and Sepiella maindroni is fast because growing, and the breeding cycle is short, is desirable enhancement species.Because squid larva can produce the phenomenon of ink-jet in transportation, the effect thus impact is released, therefore great majority adopt fertilized egg to hatch the mode of releasing in inkfish spawning field original position.But fertilized egg, when spawning ground is hatched, usually can be blown off by stormy waves or be destroyed by other marine organisms, greatly certainly will reduce the survival rate of hatchability of fertile eggs and Newly hatchled, affect effect of releasing.
Utility model content
The utility model is the above-mentioned deficiency in order to overcome prior art; provide a kind of in Sepiella maindroni releasing process for making fertilized egg being fixed, to protect and Newly hatchled obtains short-term guard space, to improve the enhancement releasing assembly of hatchability of fertile eggs and Newly hatchled survival rate.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Sepiella maindroni fertilized egg enhancement releasing assembly of the present utility model, comprise the framework in cuboid and some collection egg apparatus being positioned at lower portion, described framework is provided with the collection egg apparatus fixed mount that can coordinate with framework end face, collection egg apparatus fixed mount comprises some backstays, described collection egg apparatus is fixed on below collection egg apparatus fixed mount, collection egg apparatus is arranged along the length direction of backstay, the surrounding of described framework is respectively equipped with the housing that can match with frame facet, be rotationally connected between housing and framework, the medial surface of described housing and the inner bottom surface of framework are respectively equipped with fine-structure mesh, the medial surface of described housing, the outer bottom of framework and the end face of collection egg apparatus fixed mount are respectively equipped with the coarse grid that aperture is greater than fine-structure mesh.In this programme, collection egg apparatus is used for collecting and fixing fertilized egg and Newly hatchled, and the housing of surrounding can rotating opening, and be convenient to collection egg apparatus is carried out to installing/dismounting and clears up inside, the bottom surface of housing and framework all arranges fine-structure mesh, prevents fertilized egg from sinking to seabed.Be arranged on outside coarse grid simultaneously and can provide protection for fertilized egg in framework, be convenient to fertilized egg and the young and hide stormy waves and limit other halobiontic invasion and attack.In addition only have the top of device that fine-structure mesh is not set, the squid larva hatched only independently can be swum out of after having certain travelling ability from the coarse grid of the end face of collection egg apparatus fixed mount, improve incubation rate and survival rate, reach the object improving effect of releasing.
As preferably, the bottom of described housing is connected with frame facet lower rotation, and top and the frame facet top of housing connect and fix.Such housing can rotate from frame facet easily and open.
As preferably, be parallel to each other between described backstay, described collection egg apparatus is mutually vertical with between backstay, and the backstay that collection egg apparatus is adjacent with two is respectively fixed.There is comparatively uniform space between collection egg apparatus adjacent like this, be convenient to seawater circulation and squid larva moves about smoothly.
As preferably, described collection egg apparatus comprises rectangular framework, is respectively equipped with some parallel evenly distributed static lines between the relative edge of framework.Framework and static line are used for the collection of cuttlefish fertilized egg and fix.
As preferably, in described backstay, adjacent two backstays form a backstay group, and backstay group is evenly distributed along collection egg apparatus fixed mount end face, is less than the spacing between adjacent sets with group inner position distance between tie rods.Use two backstays in a backstay group to be fixed collection egg apparatus simultaneously, reduce collection egg apparatus relative to the beat of backstay under flow action, thus improve collection egg apparatus for the fixing of fertilized egg and protected effect.
As preferably, described fine mesh number is 5 ~ 15 orders.The aperture of such fine-structure mesh is less, in incubating oosperm process, even if there be fertilized egg dropping, also effectively can collect in bottom, prevents fertilized egg or Newly hatchled from spilling.
As preferably, the aperture of described coarse grid is 1 ~ 2cm.The aperture of coarse grid is relatively large, so that the squid larva possessing travelling ability is swum out of.
As preferably, the corner of described framework end face is respectively equipped with stay cord.Arrange stay cord to facilitate, device to be carried out hanging and lifting by crane.
Therefore, the utility model has following beneficial effect: (1) fertilized egg is fixed on lower portion by collection egg apparatus, strengthens the protected effect for fertilized egg and Newly hatchled, improves the incubation rate of fertilized egg; (2) squid larva after hatching is independently swum out of after possessing certain travelling ability, improves the survival rate of squid larva; (3) can the installing/dismounting of finishing device fast, for releasing of Sepiella maindroni fertilized egg is provided convenience; (4) reclaim and can reuse more for convenience.
