Ladyfish leptocephali are found in the offshore coastal waters (5-20 miles) of the southeastern United States, including the Gulf of Mexico.
Hence, if spawning occurs in late-summer or early-fall, then it is probable that it would take approximately 3 to 5 months for ladyfish leptocephali larvae to migrate from offishore waters to protected low salinity nearshore estuaries (i.e.
In late July, on a national holiday noted for eel feasts, Japanese newspapers heralded the team's success in finding Japanese eel leptocephali. Science works that way sometimes.
(1988) postulated that Albula leptocephali from the Gulf of California have a larval duration of 6-7 months; during winter and spring months the larvae actively move into shallow, lagoon nurseries in the first hours of a nocturnal flood tide, where they metamorphose into juveniles (Pfeiler 1984).
rostrata leptocephali captured in the Gulf of Maine, and his largest individual of 49 mm TL (which would shrink during metamorphosis) was 130 d.
Early in the last century, the Danish oceanographer Johannes Schmidt succeeded in collecting small anguillid leptocephali in the Sargasso Sea thousands of kilometers away from their growth habitats in Europe and North America, which indicated that the two species of Atlantic fresh-water eels make remarkably long spawning migrations (1).
