Perch Dissection

This post will take you through how to dissect a perch! But first, let's look at some facts about perch:

Where is it found?Perch are freshwater fish, they are found in freshwater lakes, ponds and rivers that are deep enough


What do they eat?Perch eat small insects, muscles, snails, fish eggs and other perch


How do they breathe?Perch have gills, therefore they take the oxygen from the water and process that through their bodies. Even if they are in water if it is too stagnant with no flow, there is no oxygen in the water so the fish will suffocate.


Fun fact!Perch are closely related to the walleye. They can become a great nuisance in a lake.

Intestines-The intestines of the fish are digestive organs that have finger-like extensions called villi that extend in order to increase the surface area for digested food to be absorbed.

Liver-The liver of a fish both physically and chemically prepares food for absorption and digestion.

Fat bodies-These provide insulation to the fish and also store food reserves for the fish. 

Heart-The heart of a fish much like other organisms is a muscle that pumps blood throughout the body.

Kidney-This is where liquid waste gets filtered out of the blood of the fish.

Spleen-The spleen of a fish produces and performs maintenance on blood cells within the fish.

Stomach-The stomach of a fish produces bile which helps expedite digestion.

Swim bladder-The swim bladder of a fish is what provides buoyancy to the organism and prevents it from sinking.
