Sicyopterus lagocephalus post-larvae migrating in Mascarene Archipelago rivers, La Réunion Island, provide an important food source to local populations and fishing activity has a socioeconomic impact. Improved knowledge of the life traits characterisation post-larval stages should enable better understanding physiological changes triggering migratory behaviour. It would also help explain recruitment processes managers implement conservation measures for stock management. is amphidromous...
Abstract – Modelling‐governing patterns of European eel ( Anguilla anguilla L.) distribution four size classes (<150, 150–300, 300–450 and >450 mm) in the Frémur basin (northwest France) was done using artificial neural network (ANN) techniques ecological profiles. Our results demonstrate high predictive power ANN models. Some macro‐ microscale factors, such as distance from sea, depth flow velocity, have most significant influence on Influence sea appears to be very different spatial...

Abstract – For decades, the European eel Anguilla anguilla (L.) population has been declining strongly despite several management attempts, so additional experiments need to be conducted on measures. The use of freshwater protected areas advocated but their efficiency never assessed. In this study, we investigated whether structure and silver (mature migrating stage) production differ in fished within a marsh wetland (Brière, 7000 ha, Northwest France), using an intensive biological study...
The oceanic early-life history of Anguilla marmorata was examined in the southwestern Indian Ocean Mayotte, Mauritius, and Réunion islands through otolith microstructural analysis. study hatching dates, first feeding check diameter (FFD), leptocephalus (LD) metamorphosis (MD) durations, age at recruitment (AR), growth rate (OGR) glass eels revealed great variations traits relationships between them. An agglomerative nesting analysis discriminated three histories, differently represented...

Diadromous species undergo regular migration between fresh and marine waters. This behavior is found in many species, including fish, mollusks, crustaceans, some of which are commercially valuable species. Several attempts to trace the evolution this have been made Salmonidae Galaxiidae, but ambiguous phylogenies multiple character state changes prevented unequivocal conclusions. The Kuhliidae family consists 12 fish that inhabit tropical islands Indo-Pacific region. marine, partially...
Thirty migrating silver eels Anguilla anguilla were collected in a river system where algal blooms occurred yearly. Fifty per cent of eel livers contaminated by microcystin‐LR (mean ± s . d toxin level: 28·1 22·4 ng g −1 ). Contaminated ( v. healthy) had lower fish condition. Consequences this impact for the breeding potential these are discussed.
Assessing genetic connectivity among populations in high gene flow species is sometimes insufficient to evaluate demographic connectivity. Genetic differentiation quickly becomes zero as soon a few dozen migrants are exchanged per generation. This provides little information determine whether migration can ensure coupling. The resulting difficulties delineating conservation units for the management of commercially exploited marine fish well illustrated case European sea bass (Dicentrarchus...
Abstract Following the development of high-throughput sequencers, environmental prokaryotic communities are usually described by metabarcoding with genetic markers on 16S domain. However, short-read sequencing encounters a limitation in phylogenetic coverage and taxonomic resolution, due to primers choice read length. On these critical points, nanopore sequencing, rising technology, suitable for long-read metabarcoding, was much undervalued because its relatively higher error rate per read....

Abstract – Strontium/Calcium (Sr/Ca) and Barium/Calcium (Ba/Ca) ratios were measured in 60 otoliths of the French Polynesian flagtail Kuhlia malo . Both elemental needed to correctly distinguish residence marine, brackish fresh water. High Sr/Ca low Ba/Ca around nucleus all provided evidence marine residency during early life individuals. At about 0.5 mm from core, increased rapidly remained high otoliths. unstable attributed estuarine residency, whereas stable freshwater residency. These...
Two morphological characters were examined in 4099 anguillid glass eels sampled four south‐western Indian Ocean islands, and resulting identifications tested using genetic analysis. Distance between the origin of dorsal anal fins as related to total length tail caudal fin pigmentation enabled formulation a useful field identification key, which was able discriminate 4036 regional species Anguilla bicolor , marmorata mossambica excluded occurrence nebulosa labiata sample.
Maturing sub‐adults of two species anguillid eels (a female Anguilla bicolor and a male marmorata ) were collected for the first time at Réunion Island, western Indian Ocean. Both silver eels, i.e. maturing onset their spawning migration, characterized by advanced sexual maturation that has been only observed in dieffenbachii from New Zealand.
Silver stage specimens of Anguilla bicolor and A. marmorata were fished with a keep net in an estuary the Reunion island (Indian ocean). Such silver anguillids eels have not been pointed out since years 1957-1958 South Africa. This short note gives first morphometric observations these specimens, before starting histological, endocrinological otolithometrical analysis, that should contribute to better undestanding tropical species biological cycle.
