A "goo fish" is a common colloquial name for the Freshwater Drum, scientifically known as Aplodinotus grunniens. It is often referred to as "gou" or "goo" due to its distinctive sound-making ability.
Understanding the Freshwater Drum
The Freshwater Drum is a widely distributed freshwater fish native to North and Central America. It is the only species in the drum family (Sciaenidae) found entirely in freshwater, with its marine relatives typically inhabiting saltwater environments.
Etymology and Sound
The name Aplodinotus grunniens offers clues to its characteristics:
- Aplodinotus: Derived from Greek, meaning "single back," referring to its dorsal fin structure.
- grunniens: Derived from Latin, meaning "grunting," which directly references the unique "grunting" sounds the fish can produce. These sounds are created by vibrating muscles against its swim bladder and can often be heard or even felt by anglers. This "grunting" characteristic is likely the origin of common names like "goo" or "gou" fish.
Other Common Names
The Freshwater Drum is known by several other names across different regions, reflecting its varied characteristics and local familiarity:
- Drum Fish: A general term referring to its family, characterized by the sound they produce.
- Gaspergou: Another common name, especially in the southern United States, that might also be related to its sound.
- Sheepshead: Sometimes used, though this name is also applied to other fish species (e.g., the saltwater Sheepshead, Archosargus probatocephalus).
Key Characteristics and Habitat
The Freshwater Drum is typically found in a variety of freshwater habitats, including rivers, lakes, and reservoirs. They are bottom-dwellers, often feeding on mollusks, insects, and small fish. Their adaptability and wide range make them a common sight for anglers throughout their native range.
