Finfish:
Separated into freshwater and saltwater fish
Saltwater provides more buoyancy so saltwater fish can have bigger
bones,
Freshwater fish have much lighter weight skeletal structure -lots
of tiny bones which can be a frustration to diners
Fish farming has existed for 4,000 years although first fish
weren't bred in captivity until 1733 (in Germany)
Now salmon, carp, redfish, and sturgeon are among the many farm-raised
.have long been staple part of diet in coastal populations around
the world
