Centralized collecting method of tylorrhynchus heterochaetus cultured in pond

Abstract

The invention provides a centralized collecting method of tylorrhynchus heterochaetus cultured in a pond. The method comprises the steps of exposing bottom mud of the pond to be dried in advance, centralizedly collecting and soaking tylorrhynchus heterochaetus the same day, controlling the flow rate of drained water, and timely transferring and subpackaging tylorrhynchus heterochaetus. The technical problem that tylorrhynchus heterochaetus becomes mature in batches, and cannot be centralizedly collected is solved. By means of the centralized collecting method of tylorrhynchus heterochaetus cultured in the pond, large-scale centralized maturity of tylorrhynchus heterochaetus can be promoted, the collecting efficiency of tylorrhynchus heterochaetus is improved, the collecting quality of tylorrhynchus heterochaetus is guaranteed, and the economic benefit of culturing tylorrhynchus heterochaetus in the pond is increased.

Description

【Technical field】 [0001] The invention relates to artificial collection of special aquatic products, in particular to a method for centralized collection of pond cultured grass insects. 【Background technique】 [0002] Grass worm, scientific name Tylorrhynchus heterochaetus, belongs to Invertebrate Annelids, Polychaetes, Migratory Order, Nereistae, and Tylorrhynchus heterochaetus in systematic classification. Grass worms belong to estuary species, and different from traditional clamworm species in seawater areas, the larvae of grass worms can grow in fresh water. Because the grass insect lives in the paddy field for a period of time in its life cycle, people mistakenly believe that the grass insect feeds on the grass seedlings, so it is called the grass insect. Wo Chong is also known as the "Cordyceps sinensis" in the water. It has always been regarded as a delicacy in the Pearl River Delta. It has the medicinal effects of nourishing the spleen and stomach, nourishing qi and...

AI Technical Summary

Problems solved by technology

[0004] Because the grass insects can only be collected during the spring tide period of March, April, August, September, and October in the lunar calendar every year, when the grass insects are mating and breeding in groups; during this period, the grass insects are sensitive to the external environment. Improper handling is prone to breakage of worms and affects the collection effect. In addition, when the worms surface in the early morning, they last for several days, but the amount of surfacing varies every day. The traditional collection method needs to be collected every day, which is labor-intensive and low in efficiency.
