Abstract

The invention discloses an ovigerous shrimp larvae collecting and temporarily breeding device. The device is characterized by consisting of a shrimp larvae temporarily breeding tank, a parent shrimp storing tank, a baffle, a conical larvae collecting tank, a larvae collecting machine and a bracket, wherein the size of the parent shrimp storing tank is less than that of the shrimp larvae temporarily breeding tank; the parent shrimp storing tank is sleeved in the shrimp larvae temporarily breeding tank and fixed at an opening of the shrimp larvae temporarily breeding tank in a suspension manner; the top of the parent shrimp storing tank is opened, and other surfaces are nettings in 8 meshes; and the top and the bottom of the shrimp larvae temporarily breeding tank are opened, and other surfaces are bolting silks in 60 meshes. The ovigerous shrimp larvae collecting and temporarily breeding device disclosed by the invention has simple operation, and can master the density of the shrimp larvae out of the membrane in real time so as to separate the parent shrimp from the shrimp larvae; and meanwhile, the shrimp larvae can be conveniently collected.

Description

technical field

[0001] The invention relates to a device for collecting and temporarily cultivating egg-bearing shrimp seed. Background technique

[0002] In the past, in the cultivation of shrimp seedlings with ovum development, the commonly used method is to artificially pair the parents and put them into the seedling pond for natural reproduction, and then pull the net to collect the seedlings after a period of time. The conventional method has the following disadvantages: it is impossible to grasp the number of larvae produced from the film, and it is difficult to control the cultivation density; when collecting larvae, it is necessary to pull a net or use other tools to increase the mortality rate of larvae; Shrimp will prey on shrimp seedlings, increasing the mortality rate of shrimp seedlings. Contents of the invention

[0003] The object of the present invention is to provide a device for collecting and temporarily cultivating ovum-bearing shrimp seedlings aiming ...
