在池塘养鱼过程中,往往需要进行多次检查,而每次捕捞总有部分鱼体受伤,甚至死亡。全苏养鱼科学和生产联合公司研制成一种池塘专用检查性捕鱼装置。这是一个由投饲机配合的漂浮式装置,设有电极、网片、引鱼道和集鱼箱等。开始诱集主要靠池养鱼类对投饲机声响的条件反射,然后由电极装置所产生的18～24伏的直流电场对鱼群起驱赶作用,而呈扇形向外 (上接第25页)伸展的网片、带滑道的引鱼道则协助使鱼集中到集鱼箱。检查时,只要将鱼从集鱼箱中捞出,检查好后再放回池塘。整个过程鱼只有在被搬动的短时间内才同网片接触而可能使鳞被损伤。总的来说,这种捕捞装置对保护鱼体是十分有益的。
In the process of fish ponds, often require multiple inspections, and each fishing there are always some fish injuries, or even death. All-Su fish science and production joint company developed into a special inspection fishing pond device. This is a floating device that is fitted with a feeder, equipped with electrodes, mesh, fish guide and fish tank. Began to seduce mainly by pool fish feeding conditions on the sound mixer, and then by the electrode device generated 18 ~ 24V DC electric field on the fish play a driving role, but fan outward (on the next page 25) Stretched webs and guideways with slides help fish concentrate to the fish tank. Check, as long as the fish from the fish tank fish out, check back before returning to the pond. The whole process of the fish is only in a short period of time before moving into contact with the mesh may make scales are damaged. In general, this fishing device is very beneficial for the protection of fish.
