Key Takeaways

  • Fluke fish, also known as summer flounder, are a type of flatfish found in the Atlantic Ocean.
  • Fluke fish have a distinctive diamond-shaped body with both eyes located on the right side.
  • Fluke fish are popular among anglers and seafood lovers, and can be caught using a variety of techniques.

Biology and Physical Characteristics

A fluke fish swims gracefully, displaying its flat, diamond-shaped body and long, pointed fins. Its mottled brown and white coloration camouflages it against the sandy ocean floor

Anatomy and Appearance

Fluke fish are flat-bodied fish that have a distinctive appearance. They have an asymmetric shape, which means that one side of their body is different from the other. They are also left-eyed flatfish, which means that their eyes are located on the left side of their body.

The body of a fluke fish is covered with small, rough scales that help to protect them from predators. They have a brownish-green colour on their back and a white underside. This colouration helps them to blend in with the sandy ocean floor and avoid detection by predators.

Sexual Maturity and Reproduction

Fluke fish reach sexual maturity at around 2-3 years of age. Males and females can be differentiated by the size of their gonads. Males have larger testes, while females have larger ovaries.

Fluke fish reproduce by releasing eggs and sperm into the water, where fertilization occurs. The fertilized eggs then develop into larvae, which eventually settle on the ocean floor and grow into adult fish.

Lifespan and Growth

Fluke fish have a lifespan of up to 14 years. They grow relatively quickly during their first few years of life, reaching a length of around 15-20 cm. However, their growth rate slows down as they get older.

Habitat and Behaviour

A fluke fish swims near the ocean floor, blending in with its sandy surroundings. It uses its flat body to glide effortlessly through the water, searching for small crustaceans to feed on

Feeding Habits

Fluke fish are opportunistic predators, and their diet varies depending on the availability of prey. They primarily feed on small fish such as sand lance, silversides, and mummichogs. They also eat squid, shrimp, and crabs. Fluke fish are ambush predators and use their camouflage to blend in with the sandy or muddy bottom of their habitat. They wait for their prey to swim by before striking with lightning-fast reflexes.

Habitat Range and Migration

Fluke fish are found along the Atlantic coast of North America, from Maine to Florida. They prefer shallow waters near the shore, particularly in bays, estuaries, and sandy or muddy bottoms. They can also be found in deeper waters, up to a depth of around 300 feet. In the winter months, they migrate to deeper waters to avoid the colder temperatures near the shore.

Predators and Survival

Fluke fish are preyed upon by a variety of predators, including sharks, seals, and larger fish such as striped bass. They have a relatively high survival rate due to their excellent camouflage and ability to quickly bury themselves in the sand or mud to avoid detection. However, they are also heavily targeted by commercial and recreational fishermen, which can impact their population numbers. It is important to practice responsible fishing practices to ensure the sustainability of the fluke fish population.
