“…This value is consistent with the estimated progression of 3-4 km day −1 (Beaulaton & Castelnaud, 2005). Bureau du Colombier and colleagues (2009;Bureau du Colombier et al, 2007) demonstrated than the loss of weight in glass eels was related to swimming behavior. However, the measure of activity was only qualitative in that case, with or against the current.…”

“…Other glass eels can also remain under shelters and present a low degree of activity. Their propensity to migrate and glass eels' energy content appear to be related and may result in different migratory patterns, possibly leading to estuarine settlement (Bureau du Colombier et al, 2009;Bureau du Colombier, Bolliet, Lambert, & Bardonnet, 2007).…”

Video tracking in the extreme: A new possibility for tracking nocturnal underwater transparent animals with fluorescent elastomer tags

Initially developed so that an individual could be recognized in mark-recapture studies of aquatic animals, fluorescent visible implant elastomer (VIE) tags are used here for a new application in ethometry: the study of the behavior of transparent animals in dim light or in darkness using automatic tracking technology. The application and validation of this multitracking method is tested in the context of research on the estuarine migratory behavior of the glass eel (Anguilla anguilla), a crucial point to better understand the dynamics of this endangered species. The method makes it possible to measure the activity (notably the distance and speed) of four individuals as a function of tidal and nycthemeral rhythms in the same flume (a circular aquarium simulating river or estuarine conditions) across a wide time scale (from seconds to weeks).

“…Door het ontbreken van passief getijtransport wordt verondersteld dat de glasaal in het Afvoerkanaal (snel) dient te transformeren naar een actief zwemmend (gepigmenteerd) stadium om in staat te zijn verder te migreren. Dit kan gepaard gaan met energieverliezen en gedragsveranderingen die hun verdere stroomopwaartse migratie kunnen beperken of zelfs stopzetten (Edeline et al 2005, Edeline et al 2006, Bureau Du Colombier et al 2007). Er zijn dan ook geschikte schuilplaatsen nodig in het afvoerkanaal om zich te verschuilen tegen predatoren, om zich te voeden en om te verhinderen dat ze bij de volgende piekafvoer weer naar zee worden gespoeld.…”

“…Beide vaststellingen vormen een aanwijziging dat de glasalen die in de substraten worden aangetroffen reeds omgeschakeld zijn naar een sedentaire levenswijze terwijl deze van de palinggoten nog steeds trekgedrag vertonen. Onderzoek heeft namelijk aangetoond dat glasalen met een lagere conditie minder actief zijn, zich sneller zullen vestigen en omschakelen van een zoetwater-naar een zoutwatervoorkeur wat hun stroomopwaartse migratie vertraagt (Edeline et al 2006, Bureau Du Colombier et al, 2007, 2009, Sullivan et al 2009). Sedentaire glasalen zijn dan ook kleiner en hebben een lager gewicht in vergelijking met trekkende glasalen (Bardonnet et al 2003, Edeline et al 2004.…”

“…Recent results have underlined the positive role of elver body condition in locomotor activity (Imbert et al, 2008). Interestingly, glass eels' body condition (Edeline et al, 2006) and energetic status (Bureau du Colombier et al, 2007) are also involved in settlement. At the same stage, competition for shelter may induce upstream movement, and a temporal change in intra-specific relationship from gregarious to territorial has been observed in pigmenting eels (Bardonnet et al, 2005).…”

After Anguilla anguilla larvae reach the European coast, metamorphosing glass eels exhibit an estuarine migration phase and can potentially colonize the continental area. Associated behaviours to upstream movement in estuary and river basin differ strongly: passive tidal transport in estuary, active swimming beyond the upstream tidal limit. Moreover, the migratory behaviour may shift towards a density-dependent dispersal beyond this limit. A positive relationship has previously been established between glass eels' body condition and migratory behaviour in estuary and also higher in the river basin. An experiment was settled to test for the density-dependent versus migratory behaviour under controlled conditions. The relationships between some behaviours (swimming, grouping, feeding, and aggressiveness) and body condition was investigated at the individual level. Two controlled factors were crossed, leading to four combinations of high and low levels of food and temperature. The high level of food led to a lesser loss in body condition. Swimming activity was positively related to initial body condition and loss in body condition, but these two variables were not related to aggressiveness. We conclude that the density-dependent dispersal hypothesis was not reinforced by these present results. RÉSUMÉRelations entre comportement individuel et morphométrie sous différentes conditions expérimentales de température et de nourriture chez les anguilles européennes (Anguilla anguilla) L'anguille européenne est un poisson migrateur dont les larves parviennent jusqu'à nos côtes où elles se métamorphosent en civelles qui colonisent le milieu continental après une phase de migration estuarienne, suivie ou non par la colonisation du bassin versant. Les comportements associés au déplacement amont dans ces deux milieux diffèrent fortement : une nage « portée » par le courant durant le flot en estuaire, une nage active en limite amont d'estuaire. Une corrélation positive a déjà été établie entre le facteur de condition et le potentiel migratoire de l'anguille (que ce soit en estuaire ou en phase de colonisation du bassin versant).
