Are all fish edible?
Most kinds encountered by anglers are. The organs of some
species are always poisonous to man; other fish can become toxic
because of elements in their diets. The latter are most often from
tropical regions of both the Atlantic and Pacific Oceans. Scientific
literature has pinpointed danger areas in which the disease called
"ciguatera" (a disease dangerous to man) may occur in tropical and
How can poisonous fish be distinguished from edible
They cannot, without personal knowledge of the types of fish
which are at times poisonous. Frequently local customs can be relied
upon. A comprehensive three-volume publication on the subject is
entitled "Dangerous Marine Animals" by Dr. Bruce Halstead.
Why do food fish sometimes have a strong odor?
For most species, truly fresh fish is almost odorless. Fish
begin to smell "fishy" when deterioration sets in, often caused by
incorrect storage practices that bring about the release of oxidized
fats and acids through bacterial and enzymatic action.
