Like most living beings, salmon must eat to survive. If you don't feed your salmon, he will slowly lose health. Only eating bugs can keep up his strength.
If you don't eat in a very long time, your salmon will die of hunger!
During the alevin stage, you won't need to catch bugs to keep alive, since you'll be feeding off your yolk sac. But as a fry or smolt, plenty of nourishment
is essential to survival.
Some of the bugs salmon like to eat:
MAYFLY: Mayflies live underwater for most of their lives. They briefly leave when they become adults.
STONEFLY: Stoneflies are stocky, primitive insects. They live on or near stones by streams.
CADDISFLY: Caddisflies spin silk, like butterflies, to form cages for themselves.
DRAGONFLY: Dragonflies are long, lean insects with two sets of wings.
