Fish farming is the only type of aquaculture in Serbia. Fish farming is mostly carried out in cyprinid and salmonid (trout) fishponds (over 95% of the total fish produced), with considerably lower ichthyoproduction being practiced in cages and some bodies of open water such as reservoirs and channels. Serbian aquaculture currently includes 12 fish species, 4 of which are allochthonous (non-nati...

We developed and tested eight polymorphic microsatellite loci for Ponto-Caspian 'neogobiin' gobies, many of which are invasive in Eurasia and North America, whose study will aid understanding of the population genetics underlying their success. We tested samples from one to two locations from 12 taxa in the recently revised genera Babka, Benthophilus, Mesogobius, Neogobius = Apollonia, Ponticol...

Anthropogenic engineered structures alter the local ecological connectivity of river and survival habitat native fishes. The swimming performance is critical for establishing fish passage or habitat. This study evaluated four carps (black carp, grass silver carp bighead carp) with smaller body lengths (1.0–9.0 cm) in a flume. results showed that burst speed (m/s) increased length, relative (cri...

The activity of glutathione-S-transferase (GST) in blood cells, liver, spleen and gonads in five Black Sea fish species horse mackerel Trachurus mediterraneus (Staindachner), high body pickarel Spicara flexuosa (Rafinesque), shore rockling Gaidropsarus mediterraneus (L.), round goby Neogobius melanostomus (Pallas), scorpion fish Scorpaena porcus (L.) caught in coastal area of Sevastopol (Black ...

A microsatellite-enriched genomic library for marble goby (Oxyeleotris marmoratus), a freshwater fish of considerable economic value, was obtained. A total of 16 microsatellite markers were successfully isolated and characterized in a population from the Mekong River in Vietnam. These markers had 2-20 alleles with expected heterozygosity ranging from 0.0370 to 0.8927. Linkage equilibrium was ob...

In order to determine the absolute configuration of naturally occurring alloxanthin, a HPLC analytical method for three stereoisomers 1a-c was established by using a chiral column. Two authentic samples, (3S,3'S)- and meso-stereoisomers 1b and 1c, were chemically synthesized according to the method previously developed for (3R,3'R)-alloxanthin (1a). Application of this method to various alloxan...

Concentration of blood serum albumin of the round goby Neogobius melanostomus caught in Black Sea and Azov Sea was studied in relation to age, sex, maturation and season. Albumin concentration in fish from Azove Sea was 3-fold higher than in the animals from Black Sea. Albumin level in fish serum depended on fish physiological status, maturation, age, season and geographical location. The varia...
