Where Trout Feed in a River

One thing beginning fly fishermen struggle with their first time on a trout stream is locating where fish are feeding. It’s not the pattern, cast, or the retrieve that gets them in trouble, it’s the presentation and figuring out how to get that fly in the strike zone. Here’s a look at the four basic feeding zones on a typical trout stream and what percentage of the time you can generally find fish there. You might be surprised to find trout feed under the surface 90 percent of the time.

On the Surface

Trout rarely feed on the surface, hitting insects in the surface film no more than 10 percent of the time. It will be evident fish are feeding on the surface when you see boils at the surface, hear fish slurping bugs off the top or even jump out of the water to haul in adult aquatic insects as they emerge. This is a common sight in the evenings when mosquitoes are prevalent at the water’s edge.

Just Below the Surface

Same goes for the immediate subsurface bite, or the first two or three inches below the surface. Trout consume about 10 percent of their diet here as well, snacking on adult insects as they make their way to the surface. Dry flies will still work at this stage, although switching to a light nymph like a pheasant tail is probably a better idea.

 

Feeding fish in an aquarium

Not sure what you should feed your fish? Is it a meat-eater, or a vegetarian? This list of feeding types will answer that question for you.

Carnivores

Carnivores are meat-eating fish. Some prefer live prey that they can hunt down and kill before eating, such as other fish or insects. Here are some common carnivorous fish, and what they prefer to eat.

 

Hatchetfish – Prefers live foods but will accept freeze dried and flake foods.

Killifish – Eats small live foods, can be trained to accept flakes.

Knifefish – Eats live foods exclusively

Halfbeak – Prefers live foods, but will eat flakes.

Frontosa – Accepts all types of meaty foods.

Electric Catfish – Prefer live foods, but can be trained to accept freeze dried tablets.

Bettas – Prefers live foods but will accept flakes and freeze dried.

Banjo Catfish – Prefers live foods, but can be trained to accept freeze dried tablets.

Archerfish – Eats live foods exclusively.

Herbivores

Herbivores require a diet of all, or mostely, vegetable matter. True herbivores do not have a large stomach, and therefore must eat more frequently. These fish are primarily vegetarian, and should be fed accordingly.

Molly – Algae-eater that also eats vegetables such as spinach. Will also accept insects and flakes.

Farowella – Eats vVegetable tablets and algae.

Pacu – Prefers fresh vegetables, will eat vegetable flakes and fruits.

Silver Dollar – Feed fresh vegetables, vegetable flakes and tablets.

Tropheus – Acccepts algae, plants, spirulina, vegetable flakes.
