“…Without substrate to bury, the animals have ventral injuries as reported in sole (Solea solea; Ellis et al, 1997) and in the present study. In addition, the construction of the nest for spawning is a common finding (Detrich et al, 2005;Esteve, 2005) so as to protect the egg masses from predators (Meunier et al, 2009;Lehtonen et al, 2013). The importance of sand inclusion in tanks was confirmed by spawning bouts in all tanks during the second breeding period of the present study.…”

“…the climax of the agonistic contest (Picciulin et al 2006;Sebastianutto et al 2008but also Enquist et al 1990Ota et al 1999 for other fish species). This is similar to other goby species, that use multimodal communication-not only visual but also acoustic displays-for a positive resolution of agonistic interactions (Amorim and Neves 2008;Meunier et al 2009). …”

How boat noise affects an ecologically crucial behaviour: the case of territoriality in Gobius cruentatus (Gobiidae)

Gobius cruentatus emit sounds during agonistic interactions. In order to evaluate the effect of boat noise exposure on G. cruentatus territorial behaviour, we played a field-recorded diesel engine boat noise during aggressive encounters between an intruder and a resident fish in a laboratory-controlled tank. We tested two factors: role (resident vs. intruder) and condition (noisy vs. silent); the test animals underwent all the treatments in a round-robin design. Agonistic behavior of the residents was modified by boat noise: during the playback residents were more submissive and won less encounters than in the control (silent) condition. We suggest that sound production is an effective tool for territorial defense, since the impairment of acoustic communication due to the recreational boat noise diminished the ability of the resident to maintain its territory.

“…As all fish eggs and fry consumed were of P. semilunaris, and no predation on native fish eggs and/or fry was observed, there appears to be no impact on native fish fauna through direct predation. Such opportunistic egg cannibalism (see also Vašek et al, 2014 andAdámek et al, 2010) has also been observed in N. melanostomus under laboratory conditions (Meunier et al, 2009), where it was connected with males abandoning nests. The fact that egg and fry consumption at Nové Mlýny occurs primarily in May tends to confirm that the behaviour is connected primarily with P. semilunaris breeding behaviour and is not a general behaviour pattern.…”

Key-words:invasive species, Gobiidae, Proterorhinus semilunaris, diet, site-effect, sex-differencesThe tubenose goby, Proterorhinus semilunaris, has expanded its range throughout Europe. Comprehensive studies to identify its impact on native riverine ecosystems, however, are relatively scarce. Here, we evaluate dietary preferences of P. semilunaris on a non-native river to reveal any such impacts. Fish were sampled monthly over 2011-2012 from three sites along the River Dyje (Czech Republic; Danube basin) with differing population levels and food availability. Both the amount of food consumed and dietary composition varied seasonally, with site having a strong effect. Food consumed differed between males and females, but not dietary composition; while diet differed between age classes, but not food consumed. In general, Trichoptera, Chironomidae and zooplankton dominated the diet at all sites, with Trichoptera taken more often earlier in the year and zooplankton later. Mussels were always avoided, despite high abundance, while less preferred prey were occasionally taken in high numbers in response to increased availability or energy demand (e.g. spawning). Fish eggs and fry (all P. semilunaris) were only taken in high numbers at one site, being related to high population level and fry drift from a reservoir. Male feeding declined over the breeding season, presumably due to nest guarding, while female feeding declined over winter, possibly resulting in high mortality. Proterorhinus semilunaris is a feeding opportunist, which may facilitate colonisation in habitats with poor prey availability. No predation pressure on native species was observed through consumption of eggs or fry, though small/young indigenous fish may be affected through diet competition. RÉSUMÉLes gobies demi-lune, non autochtones, Proterorhinus semilunaris, montrent des diffé-rences dans le régime alimentaire liées au site, au sexe et à l'âge. Mots-clés :espèces envahissantes, Gobiidae, Proterorhinus semilunaris Le gobie demi-lune, Proterorhinus semilunaris, a élargi son aire de répartition à travers l'Europe. Cependant, les études approfondies afin d'identifier son impact sur les écosystèmes lotiques indigènes, sont relativement rares. Ici, nous évaluons les préférences alimentaires de P. semilunaris dans une rivière où il n'est pas autochtone pour révéler ces impacts. Les poissons ont été échantillonnés mensuellement sur 2011−2012 à partir de trois sites le long de la rivière Dyje (République tchèque ; bassin du Danube) avec différents niveaux de population et de disponibilité de la nourriture. À la fois la quantité de nourriture consommée et la composition régime alimentaire, effet site, différences sexuelles alimentaire variaient saisonnièrement, le site ayant un effet important. La quantité d'aliments consommés différait entre les sexes, mais pas la composition alimentaire ; le régime alimentaire différait entre les classes d'âge. En général, les trichoptères, les larves de chironomes et le zooplancton ont dominé le régime à tous ...
