Definition
Meaning
A specific, chronic, often chronic infection or inflammation affecting the eye of a rockfish or other marine species, typically caused by parasitic flatworms.

FAQ
Frequently Asked Questions
No, rockeye is a term specific to fish, primarily rockfish and related marine species. It is caused by parasites that are not transmissible to humans.
In aquaculture settings, it can sometimes be managed with anti-parasitic treatments in the water, but advanced cases often lead to blindness or require culling of the infected fish.
It is primarily caused by infection with parasitic flatworms (trematodes) of the genus *Philophthalmus* or similar, which infest the eye tissues.
No, it is a highly specialized technical term used almost exclusively by marine biologists, veterinarians specializing in fish, and professionals in the aquaculture industry.
