Abstract Anguillid eels are found globally in fresh, transitional and saline waters have played an important role human life for centuries. The population status of several species is now significant concern. threats to populations include direct exploitation at different stages, blockages migratory routes by dams other structures, changes river basin management that impact habitat carrying capacity suitability, pollution, climate change, diseases parasites. While much has been done...
Abstract The migration route and the spawning site of European eel Anguilla anguilla are still uncertain. It has been suggested that Mediterranean stock does not contribute to because there is no evidence eels leaving Sea. To test this hypothesis, we equipped eight female silver from south France with pop-up satellite tags during escapement coastal waters. Once in deeper water, quickly established diel vertical (DVM) between upper lower mesopelagic zone. Five tagged were taken by predators...
Although fish health may influence key population-level processes, particularly those dealing with natural mortality, reproduction, and growth, which, in turn, affect stock productivity, little emphasis has been placed on the links between management of marine fisheries. This article addresses this gap illustrates how knowledge could provide insight for fisheries biologists, assessment modelers, managers. The study proposes ways which consideration condition indicators (energy reserves)...
Abstract It is well known that parameters relating to physical condition and reproduction of fish provide essential data for estimating the productivity exploited populations, as case with European hake (Merluccius merluccius) in northwestern Mediterranean Sea. Although parasitism might affect these parameters, research this area very scarce (and almost non-existent). This study evaluates first time potential link between parasitism, hake. Indicators energy reserves (total lipid content...
Ecological factors may influence the number of parasites encountered and, thus, parasite species richness. These include diet, gregarity, conspecific and total host density, habitat, body size, vagility, migration. One means examining these on richness is through a comparative analysis different, but related, species. In contrast to most studies fish, which have been conducted by using data from literature, present study uses obtained investigators. Coral reef fishes vary widely in above...

Abstract The degradation in the quality of silver eel and their health could have been a major factor collapse E uropean ( A nguilla anguilla ) population. However, status spawners has poorly studied until now. This study evaluated migrant male eels from four M editerranean habitats F rance presenting different degrees contamination: C anet‐ S aint‐ N azaire, alses‐ L eucate B ages‐ igean lagoons erre R iver. We considered pathogens including nguillicoloides crassus EVEX virus concentration...
The European anchovy, Engraulis encrasicolus L. 1758, is one of the most sought-after target species in northwestern Mediterranean Sea. However, this stock currently consists small individuals, and landings are reported to have decreased considerably. main purpose study was assess, for first time, interrelationships between size, fecundity, energy reserves parasitism female anchovies, order analyse potential implications health anchovy stocks arising from current shortage large individuals....
Transitional ecosystems and, particularly, Mediterranean lagoons represent important habitats for the European eel (Anguilla anguilla) population. In these many anthropogenic pressures can disturb movements in turn, negatively affect Despite importance of during non-migrant growing stage eels, this topic is understudied lagoons. We thus aim to describe diel and seasonal phenology effect environmental drivers on movements. Videos obtained from an Adaptive Resolution Imaging Sonar (ARIS)...
We collected 396 Gobius bucchichii, Steindachner, 1870 (Teleostei, Gobiidae) in and around the marine reserve of Cerbère-Banyuls, southeast France, between March July 1994. Five species adult parasites were found: one acanthocephalan, Acanthocephaloides propinquus Dujardin, 1845 (Acanthocephala, Arhythmacanthidae); nematode, Cucullanus sp. (Nematoda, Cucullanidae); three digenetic trematodes, Helicometra (Digenea, Opeccelidae), Derogenes Hemiuridae) Deretrema scorpaenicola Bartoli, 1990...
Despite the increasing use of acoustic cameras in fish ecology and fisheries studies, quantification biases associated with this method have received little attention. In note, we used data collected from an ARIS camera, positioned a channel linking lagoon to sea, quantify differences European eel ( Anguilla anguilla ) counts size estimates made by two experienced operators. Count 58 videos were highly consistent between operators R 2 = 0.99), although statistically different. Compared known...
Ditrachybothridium piliformis is a new species from the spiral intestine of cat shark, Galeus sp., southern Pacific Ocean. This only second assigned to Ditrachybothridium. It differs type D. macrocephalum in lacking spines on scolex, character originally used diagnose genus. The diagnoses Ditrachybothridiidae and have been revised reflect this difference. further differentiated its possession pectinate spinitriches tegument scolex. holdfast structures are weakly muscularized, with no...
Acanthocephalans are polygamous parasites of vertebrates and some species known to aggregate in sexual congress mate. Such a reproductive behaviour could lead male–male competition for access females have consequences selection. We dissected 87 gobiid fish, Gobius bucchichii , harbouring 891 acanthocephalans, Acanthocephaloides propinquus . The were sexed their body sizes measured. Testicular volume was also evaluated 82 males order establish phenotypic investment relation the estimated sex...
Because parasitism is among the reasons invoked to explain collapse of Anguilla anguilla, we evaluated parasitic constraint on body condition (BC) migrant silver eels as a proxy fitness with inter-site comparisons. Metazoan parasites were studied in 149 from five sites (northern Europe). In total, 89% infected by 13 species including Myxozoa, Monogenea, Cestoda, Nematoda, and Acanthocephala. Anguillicoloides crassus was most common (56%), then Acanthocephalus clavula (30%),...
