Meristic, morphometric and distributional patterns of cyprinid fishes of the genus Neolissochilus found in Peninsular Malaysia are presented. Based on the current concept of Neolissochilus, only two species are present: N. soroides and N. hendersoni. Neolissochilus hendersoni differs from N. soroides by having lower scale and gill raker counts. Neolissochilus soroides has three mouth types (nor...

In the intestine of 10 (n = 18) cyprinid fish species collected from natural waters of Hungary, the author demonstrated oocysts which were shed unsporulated In tapwater, oocysts sporulated within 24 to 48 h In 6 of the fish species, oocysts of 2 sizes were observed Histological examnations proved that, of the morphologically similar oocysts larger ones developed in nodules in size of a pinhead ...

Many species of fish rely on their visual systems to interact with conspecifics and these interactions can lead to collective behavior. Individual-based models have been used to predict collective interactions; however, these models generally make simplistic assumptions about the sensory systems that are applied without proper empirical testing to different species. This could limit our ability...

Fish farming in Serbia takes place cyprinid (carp) and salmonid (trout) fish farms that together account for over 95% of the total produced. Cyprinids are grown warm water farms, cold designed trout. The great majority (97%) located Vojvodina, Serbia?s northern province. This paper examines how traditional carp sector was developed during recent 20- year period paying particular attention to co...
