A kind of fishing method of Mysis orientalis cultivated in ponds

Abstract

The invention discloses a fishing method of East neomysis cultured in a pond. The fishing method includes the steps that firstly, a light source is ignited in a water outlet channel of the pond to attract East neomysis to the position near the water outlet channel; a collecting net bag is arranged on the upper portion of a valve in the water outlet channel; the height of the valve and the collecting net bag are reduced, pond water which is close to the water outlet channel and carrying the East neomysis can overflow and enter the collecting net bag, the East neomysis carried in the pond water is collected in the collecting net bag, and the pond water flows outwards through the collecting net bag; the valve is lifted, and the water in the pond stops overflowing out of the valve; the East neomysis in the collecting net bag is poured into a transition barrel, and the collected East neomysis can be used as live bait of other economic aquatic animals to finish fishing of the East neomysis. The fishing method can remarkably reduce the labor intensity of workers, improve the collecting and fishing efficiency and then reduce culture cost of sepiella maindroni and other economic aquatic animals.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for fishing Mysis orientalis cultivated in ponds. Background technique [0002] Neomysis orientalis is widely distributed in the coastal areas of China, especially in coastal waters where brackish and fresh waters meet. The body length of Neomysis orientalis is about 1cm. It has high nutritional value and is rich in protein, lipids and various trace elements. High-quality live bait for various economic aquatic animals such as squid. At present, the large-scale cultivation of Mysis orientalis is usually carried out in open-air ponds located on the banks of rivers. One side of the pond has a drainage outlet with a width of more than 0.8m, and a water outlet channel connecting the drainage outlet and the external river. , A valve is set in the water outlet channel, on the one hand, it can isolate the pond and prevent the aquatic animals raised in the pond from escapin...
