What Do Perch Eat
Diet is an important part of any living creature. Just like humans, fish need certain diets in order to get the correct nutrition that promotes a healthy life.
Keep in mind that another name for Yellow Perch is just simply Perch. Perches are found in freshwater all around North America. You can recognize them by their green olive color and because they have 9 vertical green bars running down the side of their bodies.
Yellow Perches only create spawn once a year. So, if you plan on breeding them, you need to organize your schedule around a specific time. This is about when winter starts to warm up into spring.
The perch typically will spawn in water temperatures of 45 degrees Fahrenheit. Once they are larger, they require warmer water of 68 – 78 degrees Fahrenheit. When you want them to breed, you will need to lower the water temperature.
Keep in mind how changing the water temperatures will affect your grow beds, and then plan accordingly. Perches take between one year and one and half years to reach a good enough size for eating.
As always, account for their growth rate when stocking your tank. You do not want to overcrowd your tank because it creates poor conditions for your fish.
Yellow Perch Diets change throughout their life. They eat different things when they are young compared to when they are older.
Perches are considered to be very adaptable with their food preferences. When they are young, they like to eat other fish eggs and small insects. According to the University of Nebraska, Yellow perch under 130mm typically consume amphipods and chironomids. These are a type of very small crustaceans.
