Wild adult exopalaemon modestus training method

Abstract

The invention discloses a wild adult exopalaemon modestus training method. In the invention, according to the ecological habits of the exopalaemon modestus, the good living environment is provided for the exopalaemon modestus, and the exopalaemon modestus is subjected to feed training in a quantifying manner at the fixed position after the hunger stimulation, and is induced to eat particle feed by eel feed with higher protein content and more soft texture, so that the possibility that the fresh animal bait minced fillet, viscera and the like pollute water can be avoided. In the training process, the ratio of the eel feed to the particle feed is adjusted gradually, finally the exopalaemon modestus only eats the particle feed, simultaneously, the feeding time in the morning is deferred to the proper time section, so that the various inconveniences caused by the night feeding can be avoided. In the training, due the comprehensive methods such as gradual temperature raising, addition of hiding devices, arrangement of a bait table for observation, utilization of phototaxis and the like, the good training effect is obtained, the training success rate achieves 90%; and after 40-60 days, the trained adult exopalaemon modestus broods the baby exopalaemon modestus successfully, and the brooding time is reduced by 10-20 days compared with the time of the exopalaemon modestus brooded in natural water.

Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to a domestication method of adult wild Caenorhabdella prawns. Background technique
