Perch Specimen, Medium 7"-9", Plain

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.
