* Zooplankton: These microscopic animals, like water fleas and copepods, are a major food source for newly hatched brook trout fry.
* Insect larvae: As fry grow, they start consuming insect larvae like midges, blackflies, and mayflies.
* Aquatic insects: Once they reach a larger size, they can also feed on aquatic insects like stoneflies, caddisflies, and other flying insects that fall onto the water surface.
* Worms: Small worms, like earthworms and aquatic worms, are also part of their diet.
* Crustaceans: Tiny crustaceans, such as scuds and amphipods, are another source of protein.
The specific food items a baby brook trout consumes will vary depending on the availability of food in its environment.
It's important to note that baby brook trout are very vulnerable and need a constant supply of food to grow and thrive. They are often preyed upon by larger fish, birds, and other aquatic animals.
