Phenotypic plasticity of habitat use by three temperate eel species, Anguilla anguilla, A. japonica and A. rostrata
TLDR
Diversity of habitat use appears to be a common strategy of temperate eel species, and, as a life his- tory tactic, is under environmental control. Expand
Plio-Pleistocene sea level and temperature fluctuations in the northwestern Pacific promoted speciation in the globally-distributed flathead mullet Mugil cephalus
TLDR
This study successfully identified three cryptic species in M. cephalus inhabiting the NW Pacific, using a combination of microsatellites and mitochondrial genetic markers, indicating that speciation has been achieved. Expand
Migratory behaviour and habitat use by American eels Anguilla rostrata as revealed by otolith microchemistry
TLDR
Four distinct but interrelated behavioural groups were identified by the temporal changes in Sr:Ca ratios in their otoliths: (1) entrance into freshwater as an elver, (2) coastal or estuarine residence for 1y r or more before entering freshwater, and, after enteringfresh, (3) continuous freshwater res- idence until the silver eel stage. Expand
The timing of metamorphosis and growth rates of American and European eel leptocephali:: A mechanism of larval segregative migration
TLDR
The overall mean age of European elvers was significantly greater than those of American elvers, and the time of metamorphosis from leptocephalus to glass eel was determined from otolith daily growth increments in which the increment width and strontium:calcium ratios changed drastically. Expand
Distribution of albacore (Thunnus alalunga) in the Indian Ocean and its relation to environmental factors
The distribution pattern of albacore, Thunnus alalunga, in the Indian Ocean was analyzed based on catch data from the Taiwanese tuna longline fishery during the period 1979‐85. The Taiwanese tuna… Expand
Disparities in habitat use and migratory behavior between tropical eel Anguilla marmorata and temperate eel A. japonica in four Taiwanese rivers
TLDR
A. marmorata is more easily threatened by both fishing pressure and continuous habitat degradation than A. japonica, and this disparity in migratory behaviors and habitat use between species may reflect interspecific competition and adaptive radiation. Expand
Use of otolith Sr : Ca ratios to study the riverine migratory behaviors of Japanese eel Anguilla japonica.
To understand the migratory behavior and habitat use of the Japanese eel Anguilla japonica in the Kaoping River, SW Taiwan, the temporal changes of strontium (Sr) and calcium (Ca) contents in… Expand
Effects of salinity and ontogenetic movements on strontium:calcium ratios in the otoliths of the Japanese eel, Anguilla japonica Temminck and Schlegel
TLDR
Salinity in this experiment indicated that the drastic change of the Sr Ca ratios in otoliths of elvers was not due to the reduction of salinity in the coastal waters, but more likely to the development from leptocephalus to glass eel. Expand
Occurrence of the semi-catadromous European eel Anguilla anguilla in the Baltic Sea
TLDR
The evidence indicates that European eels in the Baltic Sea do not necessarily migrate into freshwater streams during the growth phase. Expand
Variation in the annual growth, by sex and migration history, of silver American eels Anguilla rostrata
Silver American eels Anguilla rostrata from the East River, Chester, on the Atlantic coast of Nova Scotia, as evaluated by the temporal pattern of Sr:Ca ratios in their otoliths, showed variable… Expand
