Embodiment 1

[0025] The collection operation is carried out when the water temperature is 22~28°C. When collecting, choose sunny mornings or evenings when the tide is low. The collection point is selected in a flat area with gentle water flow and no depression at the bottom. The average weight captured by the combination of inserting nets and pushing nets is about 7.5~7.8g. The four-fingered Spanish finfish is about 8.1~8.5cm, pay attention to the process of picking up the juvenile fish, quickly pick up the juvenile fish with a ladle and water, and pour it into the collection bucket together with the water flow. The collection action should be light, fast and accurate. , to avoid damage to the fin rays, scales and snout of juvenile fish.

[0026] Use length × width × height (90cm × 50cm × 60cm) open water tank or bucket for transportation, the water body in the tank accounts for 1 / 3 of the entire tank volume, and the DC oxygen pump is used for oxygenation throughout the transportation to e...

Abstract

The invention relates to an artificial domesticating method for eleutheronema tetradactylum. The method comprises the following steps of (1) catching; (2) transportation; (3) transfer; (4) domestication; (5) feeding; and (6) sieving. Through the domestication according to the steps, young eleutheronema tetradactylum gradually grows to the specification of adult eleutheronema tetradactylum. The method has the advantages that the domestication survival rate is high, the popularization is easy, the operation is simple and convenient, the implementation is easy, the injury to the eleutheronema tetradactylum is small, and good application prospects are realized.

Description

technical field [0001] The invention belongs to the field of fish domestication, in particular to an artificial domestication method for four-fingered horsefin.
