Andean mountain cats have not often been kept in zoos. According to Richard Weigl (2005) the captive longevity record is only two months and that was for a specimen at Philadelphia Zoo in 1964. ZooTierListe records that the species has been kept in Hannover, Leipzig and Rotterdam.
The zoo in La Paz, Bolivia has a confiscated andean mountain cat and fellow zoochater Devilfish was going to try to see it on his south american trip.
Yes, I know what you meant, I just don't think the majority of the world would trust that the research on whales being conducted by an aquarium in Japan was valid. Hix
A large chunk of those are rescued calves, never kept for a long time. (if they don't die, they get released. It's not like keeping them long-term is an option) I don't know if adults of those species have ever been kept, and if they have, it couldn't have been for long.
And even if people didn't suspect a secondary motive, such research would still be controversial. People who are opposed to whaling aren't usually too keen on live captures either. Plus, if a place figured out how to keep captive minke whales, other aquariums and marine parks might start seeking the species out for themselves.
