Abstract The study aimed at determining the concentration of heavy metals in muscle, liver, and gill tissues four fish species ( Acanthobrama marmid , Capoeta umbla trutta Chondrostoma regium ) collected from five sites Karasu River, Erzincan, between July 2019 January 2020. relationships size (length weight) metal concentrations were also investigated using Pearson correlation analysis. Concen...

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.

When Pleurotus tuber-regium was cultivated on cotton waste, rice straw, cocoyam peels and sawdusts of Mansonia altissima, Boscia angustifolia and Khaya ivorensis, the highest crude protein, crude fat and carbohydrate contents in sporophores were 29.4 (M. altissima) , 1.4 (rice straw) and 61.3% (cocoyam peels), respectively. Sporophores produced on rice straw had the greatest energy value and th...
