Interesting question. I can't remember ever using CP on sharks and rays. Sharks don't appreciate ionic copper and they don't handle hyposalinity well, so your options are limited. I have used Coppersafe with bamboo sharks, but that was 40+ years ago.

There is this paper:

Treatment of a Large Multi-species Display Exhibit with Chloroquine and Mortality Associated with Treating the Water Containing Chloroquine with Ozone - IAAAM 2018 - VIN

www.vin.com

In this study, they used a rather low dose of CP at 10 mg/l. Concurrent use of ozone use may have been a confounding factor, I can't tell for certain. I would be wary though, and certainly don't go above 10 mg/l. I have had issues with CP not controlling ich at less than 15 mg/l.
