I have a number of small bodied fishes that I want to extract gills from, so as to do morphological analayses and histopathology. The problem is: I have a lot more that I need to do the same work with that will be ready in about a fortnight. I don't have regular access to the histology lab so would ideally be able to process all the gills at once. I'm looking to see how I should best preserve the tissue for this period of time? Is that feasible without compromising the sample?

Thanks in advance.
