If we get a fresh fish, we will take a piece of the tissue. And for molecular studies, we want to store the animal' s DNA. Then we' ll preserve it in formalin, which stabilises this specimen and then, for longterm keeping, we' ll keep it in alcohol. It seems to work for hundreds of years we know, for ever we hope. We have fluid preserved fishes from 1774 which are still in good condition. You couldn' t eat them now, of course, but for science they are very valuable materials even after all that time. Hard to love? Certainly not for me. Some, to our perception, seem quite ugly but of course not to another member of their own species. As you incorporate new specimens into the collection, this feeling of continuity and your role as custodian of something that outlives you. There is a feeling of responsibility and you can become quite pleased with the role that you play. |
