First record of round goby, Neogobius melanostomus (Pallas, 1814) in the Sava River, Croatia

In June 2011, 34 specimens of round goby (Neogobius melanostomus) were caught at three different locations in the Sava River in Croatia, which is a first record of this invasive species in Danube tributaries in Croatia. Size, structure and condition of populations indicate that the species is well adjusted to its new habitat and that further range expansions are highly likely.

Ontogenic development of digestive accessory glands in larval and juvenile Vimba bream, Vimba vimba (Pallas, 1814)

The current study investigated histological development and histochemistry of digestive accessory glands of Vimba bream Vimba vimba from hatching through 60th day after hatching (DAH). The samples were randomly taken from day 1 (hatching) until the full absorption of the yolk sac at day 7 and the day after that, then with 2, 5, and 10 days intervals until 60 DAH. The development of the digestiv...

Fatty acids and fat soluble vitamins content of Black Sea round goby (Neogobius melanostomus, Pallas, 1814) during fishing seasons

The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990).  Analysis of fatty acid methyl e...
