The aim of this study was to determine the influence of environmental parameters onthe abundance of monkey goby Neogobius pallasi. A total of 526 and 163 individuals ofmonkey goby specimens were caught by electro-shocker in the Kaboodval and Shirabad Streams, respectively. The ranges of total length of the specimens in Kaboodval and Shirabad Streams were respectively 22-137.55 mm and 32.64-137....

Index words: Gobiidae Invasive species Neogobius Proterorhinus Round Goby Tubenose Goby The species identities, scientific names, and relationships of Eurasian gobies that invaded the Laurentian Great Lakes – and other species that are predicted to invade in the future – are evaluated here using recently resolved DNA characters. The Round Goby and the Freshwater Tubenose Goby entered the Great ...

Abstract Globally, fish are frequently introduced beyond their native range. Some, like Ponto-Caspian gobies, becoming invasive, achieving high colonization rates and constituting frequent prey for predators. However, little is known about the effectiveness of antipredator behaviors invaders, which may shape role in invaded community contribute to invasion success. We compared invasive gobies s...

Abstract The monkey goby Neogobius fluviatilis is an invasive Ponto-Caspian fish that enters habitats of the native gudgeon Gobio gobio in European freshwaters, likely belonging to same prey guild. Their abilities detect and avoid predation have been poorly understood, although these traits may contribute competitive advantage drive invasion success goby. We tested intra- interspecific response...

Abstract In this study, we provide the first genetically verified distribution record beyond its native range of Ligula pavlovskii, a high-impact endoparasite Ponto-Caspian gobies. According to parasitological surveys, ligulosis was detected for time in monkey goby individuals collected from Lake Balaton 2004, 34 years after lake. During survey 2018, tapeworms 44.4% sampled This prevalence is a...

The 24 hour activity patterns of three non-native gobiids (round goby Neogobius melanostomus, Western tubenose goby Proterorhinus semilunaris and bighead goby Ponticola kessleri) were assessed over 46 consecutive months between 2011 and 2014 from their occurrence in the cooling water intake of a nuclear power plant on the River Rhine, Germany. In total, 117717 gobiids were identified and classi...

Females of the stream goby Rhinogobius sp. DA with paternal care favor males courting in fast water currents, whereby they mate males of high parental ability. Here we examined female choice of male nest size of this goby in laboratory. The dichotomous choice experiment clearly indicated that females prefer large nests. Spawning at large nests seems to improve egg survival rates in natural habi...

Male reproductive phenotypic plasticity related to environmental-social conditions is common among teleost fish. In several species, males adopt different mating tactics depending on their size, monopolizing mates when larger, while parasitizing dominant male spawns when smaller. Males performing alternative mating tactics are often characterized by a strong dimorphism in both primary and secon...
