It was a big production! When a fish died someone would call the person that owned that fish and they would come down all upset and have to remove the dead fish and log it in the book.

At my university the psychology department especially does a lot of experiments with fish, especially bettas and zebra danios. Every year the fish are sold after the experiments have been finished to raise funds for the department and they are all extremely healthy and obviously well taken care of. Like stariel said they are kept in light and temperature controlled labs, fed live foods and basically coddled over by the researchers and students. From a course description for the year 3 animal behaviour lab course: Laboratory Projects Shoaling in zebrafish (Danio rerio) Zebrafish, like Canada geese, live in social groups; they are shoaling species. Individuals prefer to join a group rather than be alone. Their shoaling behaviour and social preferences can be studied in relation to possible benefits and costs of group-living. The published literature and past studies of zebrafish by students in Psychology 3S3 have demonstrated that group size, the physical characteristics of the group, the complexity of the habitat, and overhead cover affect shoaling behaviour and preferences. There are many questions arising from these findings as well as questions about the effects of cues of predation risk and the quality and patchiness of the environment that can be pursued. Sexual selection in Siamese Fighting Fish (Betta splendens) Most people are familiar with this spectacularly-coloured aggressive species. Until very recently there were no studies of this animal in its natural environment. The field studies indicate that the males establish territories, and females visit males on their territories for spawning. There are many questions about male-male competition and female mate choice that could be pursued. Here, are some to consider. • Do Betta splendens males modulate their aggressive displays in response to information about their opponent's aggressiveness? • Are Betta splendens females affected by the mate preferences of other females? • What characteristics of the “territories” of Betta splendens males affect female preferences in a mate? • Does the female’s choice of mate depend on the choices available?

All very fascinating areas of study with popular aquarium pets. I have heard of sexual selection studies done with livebearers as well. Sorry to ramble on but I find any scientific research done with tropical fish very interesting.

stariel Fish Master Posts: 1870 Kudos: 107 Votes: 13 Registered: 01-Feb-2001	Oh, it's not stupid. I don't have quite the credentials that LifeNoodles wants, but I am a PhD candidate in Genetics at Harvard Medical School. Oh, and I worked at a cancer research institute. On the molecular level fish cancers are very much like the human variety.

I assume, then, to make such a bold statement, that you have a phD in genetic bioengineering, given several speeches on the matter at various selective universities, and now reside at Duke, as the head of it's biomedical department, then? If not, I don't really see how you can dismiss the works of prized industrialists and nobel laureates alike as stupid.

katieb Fish Addict Posts: 697 Votes: 69 Registered: 03-Jul-2004	Kelly, Besides outside carcinogens(i.e smoking), what makes you think a human gets cancer differently from fish? I think if your going to dismiss a whole study, you should at least back up your statement. Last edited by katieb at 30-Jun-2005 11:43 I'll do graffiti, If you sing to me in French.

stariel Fish Master Posts: 1870 Kudos: 107 Votes: 13 Registered: 01-Feb-2001	I used to work in a lab with zebrafish (studying neural crest tissue formation) and those fish had a good life. Better than my fish at home, I'd bet. They lived in a temperature controlled room with timed lighting, and got live food every day. Lucky fish.
