Common strategies of anadromous and
catadromous fishes: Proceedings of an international symposium, 9-13 March 1986, Boston, Massachusetts.
Eels are
catadromous fish - the opposite of salmon and other fish that are born in rivers and streams and then migrate to the sea, where they grow to adulthood before returning to the inland waterways to spawn.
The biology of a landlocked from the normally
catadromous salmoni form fish Galaxias maculates (JENYNS) 3.
ABSTRACT: An investigation of the freshwater, anadromous,
catadromous, and currently existing and long occurring introduced species that comprise the freshwater fish fauna of New Jersey indicates the occurrence of 86 species in 24 families.
Catadromous freshwater eels have been suggested to have originated in the tropical waters near present-day Indonesia sometime around the late-Cretaceous to Eocene, and the endemic tropical species A.
Two words important to the understanding of fresh water fish are anadromous and
catadromous. Anadromous refers to any saltwater fish that migrates to fresh water to spawn.
A "
catadromous" fish, the American eel spends the majority of its life in fresh and brackish water, returning to the sea to spawn.
Salmon are anadromous (they hatch in rivers and live in the sea), while eels are
catadromous (the reverse).
The Chinese mitten crab is
catadromous. This means that it is born in saltwater and migrates to freshwater, where it spends much of its life cycle, eventually returning to salt water to spawn and die.
The release mechanism on the PSAT, which operates by electrolysis, requires a >5 ppt salinity to function, (1) which necessitates consideration when dealing with anadromous or
catadromous fishes.
