Skate Captive Breeding

image description
Our Big Skates (Raja binoculata) and Longnose Skates (Raja rhina) are prolific egg layers and we incorporate their eggs into our exhibitry. 

Skates, which are a type of egg-laying ray, produce leathery egg cases, whimsically called Mermaid’s Purses. For exhibit, Husbandry staff carefully cut a small window into the egg case so visitors can watch the embryos developing. The windows do not harm the developing skates, and the young fish hatch normally.

Our captive- bred skate eggs and juvenile skates are given to other aquariums and educational institutions around the country for their displays.

Longnose Skates that were born here are beginning to produce eggs of their own. They will be our second generation of captive-bred animals.
