Some people with CHF are also at a higher risk of sudden death from serious problems with the. rhythm of the heart. Symptoms of heart attack include chest pain (crushing, squeezing pain or tightness in the chest), difficulty breathing, shortness of breath, sweating, nausea, vomiting, and loss of consciousness.
Whatever the color, I always cook trout with the skin on; it helps hold the meat together, as well as providing flavor (most of which is in the thin fat layer just under the skin). I also like to eat the skin -- the tiny scales are entirely edible -- but some prefer to leave it behind on the plate.
In rivers, streams, and most lakes, the principle diet of any trout is the nymph or larvae form of insects. Most aquatic insects spend most of their lives as nymphs or larvae under-water, before emerging as winged insects to breed.
