At the same time, these are the important areas for the migration routes of anadromous and catadromous fish species (McLusky and Elliot, 2011).
A diadromous life history includes catadromous species (species that migrate from freshwater to the sea as adults to spawn, e.g.

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).
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).
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.
