Abstract

The invention relates to a device and a method for automatically adjusting the light intensity during the zoea larvae stage of mud crab. The device includes a light shield layer, an intelligent controller and a light sensor group. The light shield layer is formed by overlapping a plurality of translucent plastic films together, and each of the translucent plastic films can be unfolded or folded under the control of the intelligent controller. The light sensor group is used to detect the current light intensity and transmit the detected current light intensity to the intelligent controller. Theintelligent controller makes the translucent plastic films in the light shield layer unfolded or folded according to the received current light intensity. The device and the method of the invention can improve the survival rate of the zoea larvaes of mud crab.

Description

technical field [0001] The invention relates to the technical field of mud crab breeding, in particular to a device and method for automatically adjusting light intensity in the mud crab larval stage. Background technique [0002] During the breeding process of blue crab seedlings, the survival rate of seedlings is low, especially in the stage of daphnia, which cannot successfully develop to the stage of megalopa. The blue crab has a certain phototaxis in the stage of daphnia, and the light intensity can affect the active feeding and development of the mud crab to a certain extent. The change of , greatly affected the survival rate of seedlings in the mud crab stage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device and method for automatically adjusting light intensity during the stage of mud crab larvae, which can improve the survival rate of mud crab larvae. [0004] The technical solution adopted by ...
