Otolith Sr:Ca ratios of the African longfinned eel Anguilla mossambica and giant mottled eel Anguilla marmorata from nine freshwater sites in four rivers of South Africa were analysed to reconstruct their migratory life histories between freshwater and saltwater habitats. For A. mossambica, the Sr:Ca ratios in the otolith edge differed significantly among rivers and had large effect sizes, but did not differ among sites within a river. Otolith Sr:Ca ratios did not differ among rivers for A…

Migratory history of African longfinned eel Anguilla mossambica from Maningory River, Madagascar: discovery of a unique pattern in otolith Sr:Ca ratios
The migratory life histories were investigated for 30 African longfinned eels (Anguilla mossambica) of the yellow eel stage from the Maningory River, East Madagascar using otolith Sr:Ca ratios and…
Opportunistic migration and habitat use of the giant mottled eel Anguilla marmorata (Teleostei: Elopomorpha)
TLDR
It is now evident that their movement into freshwater is not an obligate migratory pathway but should be defined as an opportunistic catadromy, with marine and estuarine residents as ecophenotypes.
Habitat segregation and migration in tropical anguillid eels, Anguilla bengalensis bengalensis and A. bicolor bicolor
TLDR
Their habitat use, migratory history, and habitat distribution indicate that habitat segregation occurs between the two species, leading to the different habitat preferences in tropical river systems.
Variations in the migratory history of the tropical catadromous eels Anguilla bicolor bicolor and A. bicolor pacifica in south-east Asian waters.
TLDR
The wide range of otolith Sr:Ca in both subspecies indicates that the habitat use of these tropical eels was opportunistic among fresh, brackish and marine waters during their growth phases following recruitment to coastal areas.

Genetic variability and demographic history of Anguilla mossambica (Peters, 1852) from continental Africa and Madagascar.
In this study, population genetic and demographic parameters were inferred using sequence data from 151 individuals of Anguilla mossambica originating from continental south and south-east Africa and…
Skin coloration and habitat preference of the freshwater Anguilla eels
TLDR
The different habitat preference between marbled and plain eels in the tropical/subtropical areas are likely a result of adaptive evolution to avoid potential interspecific competition, and this finding is meaningful for developing applicable management plans for eels.
Pseudodactylogyrus anguillae (Yin & Sproston, 1948) from the giant mottled eel Anguilla marmorata Quoy & Gaimard, 1824, in the Phongolo River, South Africa: an invader on the African continent.
TLDR
This report reports on the first infection of Pseudodactylogyrus anguillae from the giant mottled eel Anguilla marmorata from the Phongolo River (South Africa) using classic morphological and molecular methodologies and clarifies the introduction status category of this parasite as alien and invasive.
Fish migration in the 21st century: opportunities and challenges.
TLDR
Understanding migration, including partial migration, as a component of their wider biology, as well as ecosystem function in general, remains critically important, and Studying fish migration can present some particular challenges.
Propagule pressure drives establishment of introduced freshwater fish: quantitative evidence from an irrigation network.
TLDR
The quantitative link between propagule pressure and success and rate of population establishment confirms the driving role of this factor in fish invasion ecology.

Otolith Sr:Ca and Ba:Ca may give inconsistent indications of estuarine habitat use for American eels (Anguilla rostrata)
Temporal patterns in otolith Sr:Ca and Ba:Ca ratio values of American eels Anguilla rostrata from two sites in western Newfoundland gave insight into the use of freshwater and saline habitats. Mean…
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.
Life history of American eel Anguilla rostrata: new insights from otolith microchemistry
TLDR
Development of a simple, comprehensive residence and inter-habitat migration classification scheme would greatly assist the interpretation and comparison of otolith microchemistry studies and highlight the importance of brackish and marine waters as areas of eel production.
Decreased Sr/Ca ratios in the otoliths of two marine eels, Gymnothorax reticularis and Muraenesox cinereus, during metamorphosis
TLDR
Sr/Ca ratios in the otoliths of 2 marine eels, the moray eel Gymnothorax reticularis and the pike eel Muraenesox cinereus, decreased greatly when the crystal structure of otolith daily growth increments changed from concentric to radiate form, similar to freshwater eels (Anguilla spp.).
Evidence of different habitat use by New Zealand freshwater eels Anguilla australis and A. dieffenbachii, as revealed by otolith microchemistry
TLDR
These 2 southern temperate species may have the same behavioral plasticity regarding whether or not to enter freshwater or remain in marine environments, as has been recently documented in several northern temperate anguillid species.
Facultative habitat selection in Pacific tarpon Megalops cyprinoides as revealed by otolith Sr:Ca ratios
The Pacific tarpon Megalops cyprinoides is a euryhaline fish that is widely distributed in offshore waters of the tropical and subtropical Indo-Pacific Ocean. It spawns in offshore waters and the…
Misidentification of the migratory history of anguillid eels by Sr/Ca ratios of vaterite otoliths
Most fish otoliths are composed of aragonite, but occasionally they form a mosaic with its polymorph, vaterite. We found an unusual mosaic structure of extremely low strontium to calcium (Sr/Ca)…
Migratory patterns and contribution of stocking to the population of European eel in Lithuanian waters as indicated by otolith Sr:Ca ratios.
TLDR
Otolith Sr:Ca ratios were examined to evaluate the contribution of the stocked eel Anguilla anguilla elvers, which have been stocked in Lithuanian waters and mixed with naturally recruited eels for several decades, to the native eel population, and do not support the hypothesis that the eel fishery in the Curonian Lagoon depends mostly on stocking.
Drastic changes in otolith strontium/calcium ratios in leptocephali and glass eels of Japanese eel Anguilia /aponica
TLDR
X-ray intensity maps suggest that the changes in Sr content and Sr/Ca ratios are associated with metamorphosis, and such changes seem to be related to events, such as beginning of vertical migration or differing current influences, occurring during the oceanic migration of Japanese eel leptocephali.
