This medium plain preserved grey perch specimen has a length of 7"-9". This provides adequate size to locate internal organs and external structures at an economy cost for fish dissections. Species is typically Pomadayses magranthus. Occasionally we substitute yellow perch, Perca flavescens, based on supply availability.
Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.

In sealed, original packaging, our preserved specimens are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.
Once the original package is opened, use specimen within one month. For best results, observe the following storage procedures:
- Store specimen in heavy-duty, zip-lock bags to minimize drying between dissections.
- Specimen will slowly dry out or become contaminated in zip-lock bags; add a teaspoon of Specimen Holding Fluid to retain moisture.
- Freezing or refrigeration is not necessary and may damage fragile tissues.
