Description

一种浮游幼虫的集苗装置A seedling collection device for planktonic larvae

技术领域 technical field

本发明涉及浮游幼虫的收集,具体涉及一种浮游幼虫的集苗装置。 The invention relates to the collection of planktonic larvae, in particular to a device for collecting seedlings of planktonic larvae.

背景技术 Background technique

水产养殖是我国海洋经济发展的一个重要组成部分,而水产育苗生产是水产养殖行业中的基础。在人工育苗过程中,一些水生经济动物的幼体阶段多以浮游幼虫为生物活饵料,如双壳贝类幼虫、轮虫、枝角类、桡足类、卤虫等浮游幼虫,这些幼虫由人工培育获得。在幼虫培育过程中,由于其生理代谢和残饵的恶化,需要经常倒池换水,因此对浮游幼虫也要进行集苗转池。传统的浮游幼虫的集苗方法是在培育池出水口端放置筛绢网布或筛绢网箱,海水通过筛绢网孔流出,浮游幼虫则被拦滤在筛绢网布上或网箱内。但由于幼虫本身较小,而网目又很密,从而大量幼虫受水压作用堆积在筛网内侧的滤水面易引起网眼堵塞,滤水不畅,严重影响了工作效率;且取苗时极易造成大量浮游幼虫因机械损伤而死亡,而且需两人以上协同操作,费时又费力。如专利申请号:200710027662.8,发明名称为“一种双壳类浮游幼虫集苗方法及使用的集苗器”,公开了150-350目网孔的锥形筛绢网袋,进水管、出水管、集苗器和水泵,主要利用锥形筛绢网袋过滤,水泵主动排水,浮游幼虫富集在集苗器中,但由于其后端为封闭式,没有解决取苗不便和幼虫易受压损伤的问题。因此,如何提高浮游幼虫集苗倒池的成活率,减轻作业强度,实现浮游幼虫高效无损连续收集是进一步提高水产育苗水平,增加育苗产量需要亟待解决的问题。 Aquaculture is an important part of my country's marine economic development, and aquaculture nursery production is the foundation of the aquaculture industry. In the process of artificial breeding, the larvae of some aquatic economic animals mostly use planktonic larvae as biological live bait, such as planktonic larvae such as bivalve mollusk larvae, rotifers, cladocera, copepods, and artemia. Cultivated to obtain. In the process of larva cultivation, due to the deterioration of its physiological metabolism and residual bait, it is necessary to frequently pour the pond to change the water, so the planktonic larvae should also be collected and transferred to the pond. The traditional method of collecting seedlings of planktonic larvae is to place a sieve cloth or a sieve net box at the outlet of the cultivation pond, the seawater flows out through the sieve mesh holes, and the planktonic larvae are filtered on the sieve cloth or in the cage . However, because the larvae themselves are small and the mesh is very dense, a large number of larvae are piled up on the filter water surface inside the screen by the water pressure, which can easily cause blockage of the mesh and poor water filtration, which seriously affects the work efficiency; It is easy to cause a large number of planktonic larvae to die due to mechanical damage, and more than two people need to cooperate to operate, which is time-consuming and laborious. Such as the patent application number: 200710027662.8, the title of the invention is "a method for collecting seedlings of bivalve planktonic larvae and the seedling collecting device used", which discloses a conical sieve tulle bag with a mesh size of 150-350 meshes, water inlet pipes, and water outlet pipes. , Seedling collection device and water pump, mainly use conical sieve tulle bag to filter, water pump actively drains water, and planktonic larvae are enriched in the seedling collection device, but because its rear end is closed, it does not solve the inconvenience of taking seedlings and the larvae are easy to be pressed The problem of damage. Therefore, how to improve the survival rate of planktonic larvae collection and pouring ponds, reduce the intensity of work, and realize efficient and non-destructive continuous collection of planktonic larvae is a problem that needs to be solved urgently to further improve the level of aquatic seedling cultivation and increase the production of seedling cultivation.

本发明解决上述技术问题所采用的技术方案为:一种浮游幼虫的集苗装置,包括两端开口的锥形筛绢网袋,所述锥形筛绢网袋的前端开口上设置有弹性捆扎绳,后端开口上连接有挂钩,所述锥形筛绢网袋的后端开口的直径不大于1/5前端开口的直径。 The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a seedling collecting device for planktonic larvae, comprising a conical sieve tulle bag with openings at both ends, and an elastic binding is arranged on the front opening of the conical sieve tulle bag. Rope, the rear end opening is connected with a hook, and the diameter of the rear end opening of the conical sieve tulle bag is not greater than the diameter of 1/5 of the front end opening.

所述锥形筛绢网袋的网孔为100-350目。 The mesh of the conical sieve tulle bag is 100-350 mesh.

与现有技术相比,本发明的优点在于一种浮游幼虫的集苗装置,包括两端开口的锥形筛绢网袋,锥形筛绢网袋的前端开口上设置有弹性捆扎绳,后端开口上连接有挂钩,锥形筛绢网袋的后端开口的直径不大于1/5前端开口的直径;这样锥形筛绢网袋后端开放并悬挂,可随时将网中的浮游幼虫从后端带水移出,克服了传统收集装置因筛绢网袋网眼堵塞而引起出水不畅和后端封闭取苗不便的弊端,实现了滤水区与幼虫富集区的分离,从而达到高效连续收集的特点;绝大部分海水已在锥形网袋的前、中部流出,通过筛绢网袋后端的水流压力较小,幼虫顺流集中在该处,避免了幼虫的损伤,提高了成活率。同时,因操作简单,可实现单人操作,节省了人力资源,大大提高了生产效率,对水产育苗技术升级具有良好的推动作用。 Compared with the prior art, the present invention has the advantages of a seedling collecting device for planktonic larvae, comprising a conical sieve tulle bag with openings at both ends, an elastic binding rope is arranged on the front opening of the conical sieve tulle bag, and The end opening is connected with a hook, and the diameter of the rear opening of the conical sieve tulle bag is no more than 1/5 of the diameter of the front opening; the rear end of the conical sieve tulle bag is opened and suspended, so that the planktonic larvae in the net can be removed at any time. The water is removed from the back end, which overcomes the disadvantages of the traditional collection device, such as poor water discharge and inconvenient seedling collection due to the blockage of the screen mesh bag, and realizes the separation of the water filtration area and the larva enrichment area, thereby achieving high efficiency. The characteristics of continuous collection; most of the seawater has flowed out from the front and middle of the conical mesh bag, and the pressure of the water flow through the back end of the screened tulle bag is relatively small, and the larvae are concentrated here, avoiding damage to the larvae and improving survival Rate. At the same time, due to the simple operation, single-person operation can be realized, which saves human resources, greatly improves production efficiency, and has a good role in promoting the upgrading of aquatic seedling raising technology.

以下结合附图实施例对本发明作进一步详细描述。 The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

实施例 Example

如图1所示的一种浮游幼虫的集苗装置,包括两端开口的锥形筛绢网袋1,锥形筛绢网袋1的网孔为100-350目(图中未显示),锥形筛绢网袋1的前端开口11上设置有弹性捆扎绳2,后端开口12上连接有挂钩3,锥形筛绢网袋1的后端开口12的直径不大于1/5前端开口11的直径;这样集苗时,用弹性捆扎绳将锥形筛绢网袋前端开口与育苗池的排水管口捆绑,锥形筛绢网袋的前、中段浸入水中,后端的挂钩悬挂,后端始终高于前端,并根据水流大小调节悬挂高度,以幼虫不溢出后端口为限,工作时浮游幼虫连水通过排水管由锥形网袋前端进入,水在网袋的前、中部透过筛网孔流出,而浮游幼虫则顺流集中在网袋的后端,又由于后端的开口设计,整个网袋内的空气也能很快排出,不会引起胀袋现象,到浮游幼虫富集后,放低后端使其低于前端,让浮游幼虫带水从后端排出,用容器收集,得到富集的浮游幼虫,基本上无损伤,成活率高,由于浮游幼虫随时带水排出,根本不会引起网眼堵塞,速度较快,生产效率较高。 A seedling collection device for planktonic larvae as shown in Figure 1, comprises the conical sieve tulle bag 1 of opening at two ends, and the mesh of conical sieve tulle bag 1 is 100-350 order (not shown in the figure), The front opening 11 of the conical screen tulle bag 1 is provided with an elastic binding rope 2, the rear opening 12 is connected with a hook 3, and the diameter of the rear opening 12 of the conical screen tulle bag 1 is not greater than 1/5 of the front opening The diameter of 11; When collecting seedlings like this, bind the opening of the front end of the conical screen tulle bag with the drain pipe mouth of the nursery pond with an elastic binding rope, and the front and middle sections of the conical screen tulle bag are immersed in water, and the hook at the rear end is suspended. The end is always higher than the front end, and the suspension height is adjusted according to the size of the water flow, so that the larvae do not overflow the rear port. When working, the planktonic larvae enter the front end of the conical mesh bag through the drain pipe, and the water passes through the front and middle of the mesh bag. The sieve holes flow out, while the planktonic larvae are concentrated at the back end of the mesh bag along the flow, and because of the opening design at the back end, the air in the entire mesh bag can also be discharged quickly, without causing bag swelling, and the planktonic larvae are enriched Finally, lower the rear end to make it lower than the front end, let the planktonic larvae discharge from the rear end with water, and collect them with a container to obtain enriched planktonic larvae, which are basically free of damage and have a high survival rate. Since the planktonic larvae are discharged with water at any time, It will not cause mesh blockage at all, the speed is faster and the production efficiency is higher.
