“…The results indicate that bighead goby and round goby (Table II) share similar diet, which implies a potential for food competition. In the Serbian stretches of the Danube, similarity between round and bighead gobies was attributed to the presence of gammarids (Simonović et al, 2001). In Hungary, low diet overlap was found in spring but higher in summer and autumn (Borza et al, 2009).…”

“…Bighead goby and round goby are now very abundant, which implies that they could play an important role in foodweb interactions in the River Danube. A few studies devoted to diet of invasive populations of bighead goby and/or round goby have brought some basic information on the species diet composition (Simonović et al, 2001;Adámek et al, 2007;Copp et al, 2008;Polačik, 2009), some of them being more comprehensive, analysing seasonal and habitat variation (Borza et al, 2009). However, none of these papers provide a complex insight into the diet niche of these successful invaders.…”

Key-words: biological invasions, diet composition, feeding strategy, diet competition, DanubeBighead goby (Neogobius kessleri) and round goby (Neogobius melanostomus) have been invading new non-native areas about two decades successfully. In this study, diet spectrum, seasonal variation, feeding strategy and diet overlap between these two invasive species were assessed. Materials were collected from the Danube at Bratislava by fishing rods and/or electrofishing. The diet spectrum of both species was diverse: a total of 46 food types in bighead goby and 51food types in round goby were observed. Dikerogammarus sp., chironomid larvae and Corophium sp. were the most predominant food types in bighead goby, whereas in round goby, chironomid larvae, Corophium sp., bryozoans and Cladocera predominated. The diet varied over seasons. In the Slovak part of the Danube, bighead goby and round goby have adapted to local food resources, consuming diverse food from small to large items, both with soft and/or hard body. This enhances the capability of these invasive species to spread successfully. It appears that even if both exploit similar food resources, their proportional content differs. Further differences between these gobies were also found in their food behaviour and feeding strategy. Both species tend to be specialists where possible, but round goby demonstrates higher flexibility towards general feeding strategy. RÉSUMÉLes gobies invasifs de Kessler Neogobius kessleri et le gobie à tâches noires N. melanostomus (Teleostei, Gobiidae) sont-ils en compétition pour la nourriture ? le gobie de Kessler et le gobie à tâches noires se sont adaptés à des ressources alimentaires locales, consommant une nourriture variée allant de petites à de grandes proies, à corps mou et/ou dur. Cela augmente la capacité de ces espèces envahissantes à se propager avec succès. Il semble que même si les deux espèces exploitent des ressources alimentaires similaires, leurs proportions diffèrent. D'autres différences entre ces gobies ont également été trouvées dans leur comportement alimentaire et leur stratégie d'alimentation. Les deux espèces ont tendance à être des spécialistes lorsque cela est possible, mais le gobie à tâches noires démontre une plus grande flexibilité allant vers une stratégie alimentaire plus généraliste.

“…As construction of the first dam began in 1964, however, there is a likely connection here with its movement upstream. While occurrence was initially rare, the species had become common in the Iron Gates reservoir by the 1990s and went on to colonise the lower reaches of tributaries and fast-flowing brooks (Janković, 1996) as well as several other sites along the Serbian stretch and up into the River Sava (Simonović et al, , 2001. By 2004/05, the species was common in the Croatian Danube (Jurajda et al, 2005).…”

“…This species is commonly found in the Black Sea without any market value just as G. niger which are no management measures on this species in Turkey. There are numerous studies on all these species in Turkish and other seas in the world (Lodge, 1993;Skora and Stolarski, 1993;Macinnis and Corkum, 2000;Simonovic et al, 2001;Corkum et al, 2004;Kurt, 2005;Engin, 2008;Gümüs and Kurt, 2009;Sokolowska and Fey, 2011). …”

Uranoscopus scaber, Neogobius melanostomus and Gobius niger are called non-commercial fish species and also caught as discarded in Turkish fisheries. Samplings were carried out by bottom trawl, gillnet, purse seine net operations in the Turkish Black Sea coasts. The results of the study showed that age of these species were 0-V ages for Uranoscopus scaber and Gobius niger, and 0-VII ages for Neogobius melanostomus for both sexes. The von Bertalanffy growth parameters, total mortality rate (Z), natural mortality rate (M) and fishing mortality rate (F) were calculated for each species separately. Keywords: Age, growth, mortality rates, Uranoscopus scaber Neogobius melanostomus, Gobius nigerÖz: Uranoscopus scaber, Neogobius melanostomus ve Gobius niger Türkiye balıkçılığında ekonomik olmayan balıklar olarak adlandırılmakta ve ıskarta edilmektedirler. Bu çalışmanın örnekleri Karadeniz kıyısında kullanılan dip trolü, uzatma ağı ve gırgır ağları ile avlanmıştır. Bu çalışmadan elde edilen sonuçlar, Uranoscopus scaber ve Gobius niger türünün yaşlarının 0-V arasında, Neogobius melanostomus türünün ise 0-VII yaş arasında değiştiğini göstermiştir. Von Bertalanffy büyüme parametreleri, toplam ölüm oranları, doğal ölüm oranları ve balıkçılık ölüm oranları ise her tür için ayrı ayrı hesaplanmıştır.
