Centrarchidae

Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Perciformes (formerly belonging to the deprecated order Centrarchiformes), native only to North America. There are eight universally included genera within the centrarchid family: Lepomis (true sunfishes), Micropterus (black basses), Pomoxis (crappies), Enneacanthus (banded sunfishes), Centrarchus (type genus, consisting solely of the flier C. macropterus), Archoplites (Sacramento perch), Ambloplites (rock basses), and Acantharchus (mud sunfish). A genetic study in 2012 suggests that the highly distinct pygmy sunfishes of the genus Elassoma are also centrarchids. The centrarchid family comprises 38 identified species, 34 of which are extant. It includes many popular game fishes familiar to North American anglers, such as the rock bass, largemouth bass, bluegill, pumpkinseed, green sunfish and crappies. Most sunfish are highly valued panfish for sport fishing, and have been introduced in many areas outside their native ranges, sometimes becoming invasive species. While edible, they are not commercially marketed as food fish. Family members are distinguished by having a laterally compressed body shape, 6 to 9 anal spines, and 2 dorsal fins (spinous first dorsal and rayed second dorsal) which are fused. The number of dorsal spines varies from 6 to 13. All species in Micropterus and Lepomis have 3 anal spines, which distinguishes them from the other genera in the family. The pseudobranch is small and concealed. Body size varies widely within the family with the black-banded sunfish at just in length, while the largemouth bass is reported to reach almost in extreme cases. Many of the species within Centrarchidae can be separated into two main groups based on the two most common genera (Micropterus and Lepomis). Species in the genera Lepomis are defined by a deep or more round body shape, smaller mouths, and obtaining food through suction feeding.

Bluegill

The bluegill (Lepomis macrochirus), sometimes referred to as "bream," "brim," "sunny," or "copper nose" as is common in Texas, is a species of North American freshwater fish, native to and commonly found in streams, rivers, lakes, ponds and wetlands east of the Rocky Mountains. It is the type species of the genus Lepomis (true sunfish), from the family Centrarchidae (sunfishes, crappies and black basses) in the order Perciformes (perch-like fish). Bluegills can grow up to long and about .

Spawn (biology)

Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring.

Forage fish

Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers.
