متن کاملEffects of Phosalone on Mineral Contents and Spinal Deformities in Common Carp (Cyprinus carpio, L.1758)
The objective of this study was to evaluate the effect of phosalone on some mineral contents, morphological abnormalities and spinal deformities in common carp (Cyprinus carpio, L.1758). Fish were exposed to 0.15, 0.30 and 0.60 mg L of phosalone using a semi-static exposure regime for 14 days. Experiments were conducted in triplicate for control treatments and phosalone concentrations. At the e...

The study was conducted for 134 days. Common carp fry (60g ± 0.3g) were fed using two different diets containing only plant protein sources, without any animal protein inclusions. Diets were administered by two different methods: an automatic band feeder (diet 28/7 F and 28/15 F) for 12 hours a day (9.00 a.m. – 9.00 p.m.) and by hand (diet 28/7 H and 28/15 H) once a day (at 9 am).
