Abstract

The invention relates to the technical field of water body biological sample analysis equipment, and particularly discloses a separation device after collection of fish eggs and larvae, a box body comprises a box body upper part, and at least two layers of screens are arranged on the side wall of the box body upper part; the box body middle part is detachably connected to the lower end of the upper part of the reel box body, and the side wall of the middle part of the reel box body is provided with an electrodeless dimming lamp strip for irradiating the reel screen; and the base plate part is detachably connected to the lower end of the middle of the reel box body, and the reel base plate part can contain the upper portion of the reel box body so that the reel screen can be immersed into the reel base plate part. By means of the arrangement, on the basis that it is guaranteed that the fish eggs and the fish larvae can be effectively separated after being collected, the separation device for the collected fish eggs and the collected 77 fish larvae can achieve the purpose of recognizing the development periods of the fish eggs and the fish larvae through the anatomical lens.

Description

technical field [0001] The invention relates to the technical field of water biological sample analysis equipment, and more particularly, to a separation device for fish eggs, larvae and juveniles after collection. Background technique [0002] In addition to the fishing of large phytoplankton in the field sampling process, it is also a difficult matter in the selection and sorting of samples. Traditionally, due to many limitations in the selection process of collected samples, the samples cannot be selected as many as possible, especially fish. Eggs and newly hatched larvae and juveniles exist transparently in the water body and are difficult to distinguish with the naked eye. [0003] Juveniles are sufficiently developed to be sorted in petri dishes and identified by morphological analysis. Because the fish eggs themselves are relatively small, especially after absorbing water, they become transparent and difficult to distinguish, so it is not clear whether there are fish...
