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 ...
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.
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).
Smelts are one of the best choices of freshwater and saltwater fish to eat, as one of the types of edible fish with the lowest amount of mercury. [5] Smelts can be found in the Atlantic and Pacific oceans, as well as in some freshwater lakes across Canada. Smelts were eaten by many different native peoples who had access to them.
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.
The two major classes of molluscs have representatives in freshwater: the gastropods (snails) and the bivalves (freshwater mussels and clams.) It appears that the other classes within the Phylum Mollusca -the cephalopods, scaphopods, polyplacophorans, etc. - never made the transition from a fully marine environment to a freshwater environment.
It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America and Australia. [4] [5] Native to China, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp).
Salmon are typically anadromous: they hatch in the shallow gravel beds of freshwater headstreams and spend their juvenile years in rivers, lakes and freshwater wetlands, migrate to the ocean as adults and live like sea fish, then return to their freshwater birthplace to reproduce. However, populations of several species are restricted to fresh ...
