Plankton collecting device

Abstract

The invention relates to a plankton collecting device. The device comprises a drag pipe, a plurality of guide pillars, a driver and a catching device; the drag pipe is formed into a closed loop by a hollow drag pipe along the shore; the guide pillars pass through a shaft pulley of a straight vertical shaft and arranged on a plurality of corners on the shore respectively, and each pulley emerges from the water surface through a pontoon to guide the drag pipe to slide; the driver comprises an engine which drives at least one pair of driving wheels and drives the drag pipe to detour through friction force; the catching device comprises a curved bar and a trail net, one end of the curved bar can penetrate through the portion between two diving wheels and is fixedly connected to the drag pipe, and the other end of the curved bar drags the funnel-shape trail net. According to the plankton collecting device, the drag pipe drags the trail net to detour along the shore, and plankton in water can be caught into a net on the passing place.

Description

technical field

[0001] The invention relates to a plankton collecting device, in particular to a plankton collecting device which is dragged by a floating rail to drag a feeding cylinder and a trawl around the periphery of a culture pond for automatic feeding and fishing. Background technique

[0002] As a result of rapid global warming and overfishing, species such as fish, shrimp, and shellfish along the coast of Taiwan, China have disappeared in large numbers, and fish sources have been exhausted. Surrounded by sea on all sides, Taiwan, China has unique natural resources suitable for fish, shrimp and shellfish farming. The development of aquaculture has become the best way to regenerate resources, and aquaculture fisheries are developing to replace pelagic fisheries. Among them, aquaculture fishery includes freshwater aquaculture pond cultivation, saltwater aquaculture pond cultivation, economic fish species such as tilapia, milkfish, eel, grouper, sea bream, shrimp and s...
