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]
The protection of 30% of Earth's surfaces by 2030 may encompass freshwater habitat and help protect these threatened species. [ 8 ] There is an increasing trend in freshwater fish for local taxonomic, functional, and phylogenetic richness in more than half of the world's rivers. [ 8 ]
Perch have a long and round body shape which allows for fast swimming in the water. True perch have "rough" or ctenoid scales. Perch have paired pectoral and pelvic fins, and two dorsal fins, the first one spiny and the second soft. These two fins can be separate or joined. [6]

The energy content of the trout-perch was 4795 joules, whereas yellow perch and round goby energy content were lower; 4662 joules and 3740 joules respectively. [ clarification needed ] [ citation needed ] These findings are the main reason, scientists believe the trout-perch is an important source of food for other species in their habitat.

Clinostomum marginatum is a yellow flatworm that can grow up to 6.4 millimetres (0.25 in) in the flesh of freshwater fish or the muscle of frogs. Distinguishing characteristics of this parasite in the "miracidium" stage are three eyespots located on the mid-dorsal line, posterior of lateral papillae.
