Fish passes facilitate fish movement in fragmented river systems, yet they can also provide important habitat functions. This study investigated the community composition of different constructed types (fluvial habitats, floodplain ponds) within relation to characteristics order deduce recommendations for fish-friendly designs such structures. structures differed significantly from those main r...

Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%.

The larval development of the nematode Contracaecum rudolphii (Rudolphi, 1819), a common parasite of the proventriculus of cormorants, was experimentally studied. Within the eggs cultivated in freshwater under laboratory temperatures of 20-22 degrees C, the developing larva undergoes two moults on days 4-5, attaining the third larval stage. Most of the ensheathed third-stage larvae, 291-457 mic...

The radiological differences between the urinary tract of  Dicentrarchus labrax, Sparus aurata, Tinca tinca, and Cyprinus carpio are shown. In fresh water teleosts the urinary bladder is sigmoid and a short urethra leads to the urinary pore. Genital and anal pores are present. In Sparus aurata the urinary bladder has a globoid shape. In Dicentrarchus labrax the urinary bladder is smaller and el...

Recent Georgia’s fish fauna includes four Capoeta species: C. capoeta (Kura River basin), kaput (Araxes and its left tributaries, the Akhuryan Mezamor rivers), sieboldii (East South–East Black Sea river basins), banarescuii (Chorokh basin). Based on morphological data analysis new species of genus — svanetica sp. n. is described. It more similar to damascina complex group (Anatolian–Iranian gro...

This study was conducted to determine length-weight and length-length relationships, relative condition factor (Krel) and Fulton?s condition factor (K) for five species including Scardinius erythrophtalmus, Carassius auratus gibelio, Cyprinus carpio, Tinca tinca and Hemiculter leucisculus belonging to Cyprinidae family. Fish sampling was carried out by gill net and fyke net in the western regio...
