condition factor of fish species is very important parameter for understanding fish biology and pathology. for that purpose, we sampled 120 fish individuals from the sava river at four locations (posavina region), where most of them belongs to the cyprinidae family while the others belonging to the families: percidae, siluridae, ameiuridae, esocidae and gobiidae. in total fish sample we found t...

This study was carried out in the inland waters of Muğla Basin between 2018-2019. As a result field studies and literature, it determined that there were 36 species fish belonging to 17 families (Anguillidae, Atherinidae, Cobitidae, Leuciscidae, Cyprinidae, Gobionidae, Nemacheilidae, Aphaniidae, Poeciliidae, Blenniidae, Centrarchidae, Cichlidae, Gobiidae, Moronidae, Mugilidae, Salmonidae, Silur...

We resolve the identity of the glass catfish, a species of Asian freshwater fish commonly encountered as an ornamental fish and an experimental subject that has long been misidentified as either Kryptopterus bicirrhis or K. minor. Our study indicates that the glass catfish is an unnamed species distinct from either, which we describe here as Kryptopterus vitreolus. Kryptopterus vitreolus is kno...

The ecological aspect of the behavioral and physiological adaptation fish in autumn-winter period water bodies temperate subarctic climatic zones Northern Hemisphere is considered. It has been established that studied areas with a decrease temperature form aggregations deep, low-speed sites for successful wintering. In considered life cycle, metabolism slows down to reduce depletion lipid reser...
