Characteristics of a Fish Fillet
A typical fish fillet exhibits the following characteristics:
- Shape and Size: Fillet shapes vary depending on the fish species, with some being long and slender (e.g., flounder) while others are more oval or round (e.g., salmon). The size also varies, influenced by the fish’s age and species.
- Color: The flesh of a fish fillet ranges from white (e.g., cod) to pink (e.g., salmon) to dark red (e.g., tuna). The color reflects the fish’s diet, lifestyle, and habitat.
- Texture: Fillet textures can be firm (e.g., halibut), flaky (e.g., tilapia), or buttery (e.g., salmon). These variations stem from the fish’s muscle structure and fat content.
- Lines and Veins: Fish fillets often display lines or veins running along their length. These lines represent the fish’s muscle fibers and are harmless to consume.
