Description
Technical field
The utility model relates to fish-releasing device.
Background technology
Cold water fishes comprises the sturgeon of the salmon trout of cold water, sub-cold water and lives in other fish of cold water domain etc., high with protein content, be rich in good nutritional properties and the quality of the unsaturated fatty acid such as EPA and DHA, and become international important cultivation and trade kind.China's cold water fishes existence and cultivation waters are very wide, account for the more than 1/3rd of total waters, China inland, be mainly distributed in the provinces and cities such as Heilungkiang, Xinjiang, Tibet, Qinghai, Jilin, Liaoning, Shandong, Hebei, Beijing, the Inner Mongol, Ningxia, Gansu, Yunnan, Guizhou, Sichuan, Chongqing.In these natural flood face water bodys and cultivation waters, living and comprising that sturgeon, huso sturgeon, rainbow trout, taimen, brachymystax lenok, hemp Kazakhstan, torgoch, pelyad, lawver, schizothoracin etc. nearly more than 80 plant cold water fishes, thering is high scientific research and exploitation is worth.In recent years due to the destruction of artificial overfishing and Habitat for Fish ecotope; sharply reduce as Species of Rare Fish from Qingdao natural resourcess such as wise sieve salmon, brachymystax lenok and flower cake torgochs; therefore the also input of corresponding increasing Species of Rare Fish from Qingdao population protection of country, and also obtain remarkable progress in the work of artificial propagation and Rejuvenate species.Along with the continuous propelling of work, find to adopt existing releasing device and the method for releasing, in releasing the process of cold water fish seed, the large water surface such as rivers, lake and reservoir there is the problem that survival rate is lower.
Utility model content
The purpose of this utility model is to adopt existing fry releasing device and method directly fry to be spread in the water body of the large water surface in order to solve, and causes the problem of fry mortality, and the large water surface water body of a kind of cold water fishes releasing device is provided.
The large water surface water body of a kind of cold water fishes releasing device, it comprises staving, staving handle, articulated elements, bung, rope, No. two ropes and sinker, the two ends of staving handle are connected with the upper end of staving sidewall respectively, bung is connected by articulated elements with staving, No. one rope is fixedly connected with the upper end of staving handle, No. two rope is fixedly connected with the bottom of staving, and sinker is fixed on the upper surface of bung, and sinker becomes 180 degree angle settings with articulated elements.
Cold water fishes survives optimum water temperature generally all below 25 ℃, and is summer or early autumn in the season of releasing of fry the best, and now the water body skin temperature of the large water surface water body such as rivers, lake and reservoir is higher than 30 ℃; Therefore, if fry is directly sprinkled into water body, due to the high temperature on water body top layer, fry there will be more serious high temperature stress, just cause fry also not swim in time the profundal zone mortality into lower temperature.The utility model is placed in the fry of preparing to release in the staving of the releasing device that water temperature is suitable, by a rope, the staving that the fry of releasing is housed is vertically inserted behind suitable water temperature (degree of depth) region, unclamp rope No. one, tighten up rope No. two, staving in water is flipped upside down, bung is opened under the Action of Gravity Field of sinker, the fry of releasing enters in water body, avoid the high temperature on water surface top layer stress, shortened the adaptation time of fry water temperature, the survival rate of the fry that makes to release has improved more than 60%.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model, and Fig. 2 is the vertical view of the bung of embodiment one.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the large water surface water body of a kind of cold water fishes releasing device described in present embodiment, it comprises staving 1, staving handle 1-1, articulated elements 1-2, bung 2, a rope 3, No. two ropes 4 and sinker 5, the two ends of staving handle 1-1 are connected with the upper end of staving 1 sidewall respectively, bung 2 is connected by articulated elements 1-2 with staving 1, No. one rope 3 is fixedly connected with the upper end of staving handle 1-1, No. two rope 4 is fixedly connected with the bottom of staving 1, sinker 5 is fixed on the top surface edge place of bung 2, sinker 5 becomes 180 degree angle settings with articulated elements 1-2.
The large water surface water body of present embodiment cold water fishes releasing device has simple in structure, easily operation, the advantage of successful.
Tighten up No. two ropes 4 staving 1 is tilted, then utilize the Action of Gravity Field of sinker 5, staving 1 flips upside down naturally, and bung 2 is opened.Cold water fish seedling is directly released into profundal zone, and water temperature is lower, has avoided high temperature stress reaction, thereby effectively improves the survival rate of fry.
