In the US, the term "seafood" is extended to fresh water organisms eaten by humans, so any edible aquatic life may be broadly referred to as seafood in the US. Historically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times.
Brackish water – water that has more salinity than fresh water, but not as much as seawater. It may result from mixing seawater with fresh water, as in estuaries. Breach – a whale's leap out of the water. Breaker zone – the zone where ocean surface waves approaching the shore commence breaking, typically in water depths between five and ...
Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury. Four of the most commonly eaten fish that are low in mercury are canned light tuna, salmon, pollock, and catfish. Another commonly eaten fish, albacore ("white tuna") has more mercury than canned light tuna. So, when choosing your two ...
Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish.Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins).
The wild Atlantic salmon fishery is commercially dead; after extensive habitat damage and overfishing, wild fish make up only 0.5% of the Atlantic salmon available in world fish markets. The rest are farmed, predominantly from aquaculture in Norway, Chile, Canada, the UK, Ireland, Faroe Islands, Russia and Tasmania in Australia.
A variant method of fish stocking, called ocean ranching, is under development in Alaska. There, the young salmon are released into the ocean far from any wild salmon streams. When it is time for them to spawn, they return to where they were released, where fishermen can catch them. An alternative method to hatcheries is to use spawning channels.
Freshwater bivalves are native to the Oriental biogeographic realm and to the southeastern United States and have been introduced to other regions, specifically the two genera in the Pacific Ocean Islands were introduced from Hawaii. [5] As new methods of identifying and locating freshwater bivalves improve, the distribution of where these ...
The Indian Ocean is the third largest ocean, covering 73,556,000 square kilometres, or about twenty percent of the water on the Earth's surface. Small islands dot the continental rims. The ocean's continental shelves are narrow, averaging 200 kilometres (120 mi) in width.
