Some yellow perch fisheries have been affected by intense harvesting, and commercial and recreational harvest rates often are regulated by management agencies. In most aquatic systems, yellow perch are an important prey source for larger, piscivorous species, and many fishing lures are designed to resemble yellow perch. [citation needed]

Specifically in perch, the gas bladder can vary from 12% to 25% of oxygen and 1.4% to 2.9% of carbon dioxide gas. [11] Perch reproductive organs include either a pair of testes (sperm-producing) or a pair of ovaries (egg-producing). [9] The above picture is a labeled image of the internal anatomy of the species Perch Perca flavescens.
In the early 1900s, Yellow perch (Perca flavescens) appeared in Goose Lake and other small lakes in the Lower Geyser Basin. It is believed they were either illegally introduced or were hitchhikers in official bass stocking. In 1938, fisheries managers poisoned Goose Lake and other locations known to contain Yellow perch.

The freshwater drum competes with several organisms. During its early stages in Lake Erie, it has been shown to compete with yellow perch, the trout-perch, and the emerald shiner. [25] During its adult lifetime, it competes with yellow perch and silver chub in deep water, and competes with black bass in the shoal areas. [25]
Percomorpha (from Latin perca 'perch' and Ancient Greek μορφή (morphḗ) 'shape, appearance') is an extremely large and diverse clade of ray-finned fish.With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant vertebrates.
The family contains more than 200 species in 11 genera. The perches and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family.
