Diagnosing fish diseases using air-dried, unstained slides.

Air dried smears are not exactly the best sample for making a diagnosis, but it can work, especially if there are numerous external parasites and that the smears are prepared correctly.

It’s ideal in situations where the remote site is without a microscope, or someone who knows how to use one, or knows what to look for. The slides can be prepared easily and sent by post to your nearest fish veterinarian to make a diagnosis.

To prepare the smears, simply follow the steps as per taking gill biopsies and skin mucus scrapes, and then smear these onto the glass slide. Do not add any water. Wave the slides in the air until dry.

For added diagnostic advantage, the commonly used Diff Quik stain can be applied to the smears.
