<s>[INST] The next text is a question of a member of the European parliament:"Despite a clear lack of public support, dolphinaria, and similar facilities where cetaceans are kept, still benefit from EU structural funds for the maintenance and building of extensions.  1.Can the Commission provide a list of all the dolphinaria and similar facilities that have been given EU support, for instance through theEU structural funds?  When it comes to breeding books for animals, many species are covered by sectorial breeding book schemes, but for cetaceans kept in dolphinaria there are still many issues.  2.To what extent can the Commission guarantee transparency regarding the breeding books of cetaceans in captivity and make the information contained therein public?  Cetaceans are dependent on salt water, or rather artificial seawater, in their tanks and enclosures in order to stay healthy and survive. However, more and more dolphinaria are adding chlorine to the water in an attempt to cut costs and keep the water clean.  3.As chlorine in artificial seawater has a negative impact on the welfare of cetaceans in captivity, what are the thresholds for chlorine and when will the Commission revise these, to take into account animal welfare concerns?"
