This study assessed the distribution of heavy metals in gills, kidney, and liver, correlated with severity histopathological changes, three fish species different feeding habitats (Barbus barbus, Squalius cephalus, Chondrostoma nasus) from Cri?ul Negru river, Romania. The levels copper (Cu), chromium (Cr), cadmium (Cd), lead (Pb), zinc (Zn) tissues were measured by atomic absorption spectrophot...

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...

This study investigate investigated the length-weight, length-length relationships and condition factor of eight fish species collected from Bashar River, Tigris drainage by sampling 341 specimens Alburnus sellal (Heckel, 1843), Barbus karunensis (Khaefi, Esmaeili, Geiger & Eagderi, 2017), Capoeta aculeate (Valenciennes, 1844), coadi (Alwan, Zareian 2016), Chondrostoma regium Garra gymnotho...

Some Cyprinid fish species: Cyprinion macrostomum (Heckel, 1843), Capoeta umbla Chondrostoma regium and Squalius cephalus (Linnaeus, 1758) living naturally in the Murat River, were investigated for Protozoan Crustacean parasite fauna their distribution. Fish samples collected from different stations between July 2017 - June 2019, examined Bingöl University Zoology Research Laboratory, data expl...

Background. Little is known about the seagrass wrasse, Novaculoides macrolepidotus. In January 2012 it was recorded for the fi rst time from Reunion Island. As its population increased over the years, fi eld observations were made on colour pattern variation, escape and reproductive behaviour. Regarding a cryptic and poorly documented species, these observations, despite their anecdotal form, n...
