Perch's everywhere

A little something about the perch

Perch are fish that are most commonly found in small ponds, lakes, streams, or rivers. They are relatively small in size but yet very fast and stealthy due to their fins. These fish are very sought-after by fisherman for a whole variety of things such as food or even competitions. The general body type of a perch is somewhat long and rounded. The perch can usually reach to roughly about to the size of 18 inches. They are mostly found towards the north of the USA. the largest ever caught was measured at 4 lb. 14 oz. and was measured at 24 inches. These are great fish and they are great to our environment.

Prey and Predators

Almost every cool to warm water predatory fish species, such as the northern pike, muskellunge, bass, sunfish, crappie, walleye, lake trout,and even fellow perch are predators to the perch. For food they can eat each other, smaller fish, shellfish, or insect larvae, but can be caught with nearly any bait.

The Circulatory System

The circulatory system of the perch is a typical low pressure single type system in which the heart is a single pump and there is a single circuit of blood flow. The heart is pumped through the body towards the gills and that's where the blood actually gets oxygenated. With that being said, until the blood reaches the gills the blood is deoxygenated. The blood then returns back to the heart for another round!

Evolution at its best!
