Musculoskeletal anatomy and feeding performance of pre-feeding engyodontic larvae of the European eel (Anguilla anguilla).
Being part of the elopomorph group of fishes, Anguillidae species show a leptocephalus larval stage. However, due to largely unknown spawning locations and habitats of their earliest life stages, as well as their transparency, these Anguilla larvae are rarely encountered in nature. Therefore, information regarding the early life history of these larvae, including their exogenous feeding strateg...
متن کاملEels (anguilla Anguilla (l.)) of the Lower River Shannon, with Particular Reference to Seasonality in Their Activity and Feeding Ecology
The general biology and seasonal ecology of eels from a riffle section of the lower reaches of Ireland’s largest river system, the River Shannon, were investigated. Eels at this location occurred in high densities, had a slow growth rate and were predominantly male at maturation. Although they fed to some degree all year round, foraging activity of the eels was highest in the months of May to S...
متن کاملVirulence of Aeromonas hydrophila and some other bacteria isolated from European eels Anguilla anguilla reared in fresh water
Studies were conducted to determine the pathogenicity for European eels Anguilla anguffla and rainbow trout Oncorhynchus mykiss of several stra~ns of the species Aeromonas hydrophila, A. jandaei, A. sobria, A. caviae. Plesiomonas shigelloides. Vibrio anguillarum, Pseudomonas fluorescens and Shewanella putrefaciens isolated from an eel farm. Virulence of 20 isolates obtained during epizootics fr...
متن کاملCu uptake, metabolism and elimination in fed and starved European eels (Anguilla anguilla) during adaptation to water-borne Cu exposure.
64Cu accumulation and total Cu concentrations were measured in gill filaments, plasma, liver and bile of fed and starved European eels (Anguilla anguilla) during 28 days of exposure to 12 and 94 micrograms Cu l-1. Branchial Cu uptake was found to be 0.03 and 0.13 microgram Cu g gill filament-1 h-1 at 12 and 94 micrograms Cu l-1, respectively, throughout 28 days of Cu exposure. At least during e...
متن کاملComparative imaging of European eels (Anguilla anguilla) for the evaluation of swimbladder nematode (Anguillicoloides crassus) infestation.
This study compares diagnostic imaging tools in detecting the parasitic swimbladder nematode Anguillicoloides crassus in Anguilla anguilla (L.) and focuses on ultrasound in an attempt to develop a non-destructive, field diagnostic test. Ultrasound use could allow the parasite to be diagnosed without decreasing the number of critically endangered European eels through post-mortem. In the prelimi...
