Dear colleagues, The Ministry of Environmental Protection of Ukraine is developing a national code to regulate handling marine mammals in capture and their rehabilitation. Any suggestions from local scientists and public organizations are highly appreciated. So I am looking for any existing regulations on rehabilitating cetaceans, especially on their holding in captivity and releasing, and, in general, laws and rules of holding cetaceans in captivity, especially: pool size, diet, limitations on show participation, mortality control, individual identification. I would greatly appreciate links and/or texts. Best regards, Pavel Pavel E. Gol'din PhD, Department of Zoology V. I.
