A diadromous life history includes catadromous
species (species that migrate from freshwater to the sea as adults to spawn, e.
Pollard DA (1972) The biology of a landlocked form of the normally catadromous
salmon-form fish Galaxias maculates (Yenys) with structure of the gonads.
Members of the six species of the "boucourti group" of Callinectes are catadromous
, are larger as adults, are found in the lowest salinity water of estuaries, and grow to the largest size, whereas species of the other three groups, "danae," (five species); "marginatus," (two species); and "gladiator" (one species) are smaller as adults and occur in higher and constant salinities (Norse & Fox-Norse 1982).
Fidelity to spawning grounds by a catadromous
fish, Centropomus undecimalis.
In a recent review about skipped spawning, the presence of this phenomenon was reported for at least 31 species, including marine teleosts (demersal and pelagic), freshwater fish, and anadromous and catadromous
species (Rideout and Tomkiewicz, 2011).
Common strategies of anadromous and catadromous
Among the topics are the history of fish migration research, life histories of catadromous
fishes, microchemical and schlero-chronological analyses used to infer fish migration, using drift nets to infer fish transport and migration strategies in inland aquatic ecosystems, and archival and pop-up satellite archival tags for investigating oceanodromous fish movements.
EPA detected the presence of American eel, a catadromous
species, and determined that the American shad and blueback herring--both anadromous species--are capable of using Hurricane Creek.
Freshwater eels of the genus Anguilla are catadromous
fish with long spawning migrations expanding from a few hundred for tropical eels to thousands of kilometers for temperate ones (Aoyama 2009).
American eel are facultative catadromous
species that have a life cycle that encompasses thousands of kilometers to complete (USFWS, 2011a).
like eels, bekti spend much of their lives in fresh water but lay their eggs in shallow ocean water and estuaries.
