In this study, copper toxicity, was investigated after the addition of zeolite to the diet of common carps (Cyprinus carpio). The experiment included four groups with three replicates each. The 4 group feeds were [CuSO4; CuSO4 + Zeolite; Zeolite, and the control without CuSO4 or Zeolite with three replicates each. Fishes were kept in 80 L glass aquariums with 10 fishes with a mean weight of 60.6 ± 0.2 g. At the end of each period, a necropsy was performed on fishes from each treatment, and gross clinical signs were recorded. We found significant changes in the blood parameters of the common carps with or without different levels of zeolite and copper. Changes in cholesterol (CHOL), triglyceride (TG), low density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), calcium (Ca2+), phosphorus (P+), sodium (Na+), potassium (K+), chloride (Cl-), magnesium (Mg2+), and ferrous (Fe+2) were also significant. Our results suggest that zeolite can be used in fish feeds at a rate of 40 mg/l to mitigate the toxic effects of copper.

AbstractCommon carp (Cyprinus carpio) is the most farmed freshwater fish worldwide. In recent years, use of natural products in fish diets has become popular in aquaculture, to improve fish health and growth performance. The present study investigated the effects of essential oil from the leaves of Monterey cypress (Cupressus macrocarpa; CMEO) on growth performance and blood parameters in common carp fingerlings. Identification of 96.1% of the CMEO total volatile components was achieved, with the highest contents for terpinen-4-ol and α-pinene, at 22.9% and 47.7%, respectively. After 60 days of feeding of the fingerlings with supplemented diets without CMEO (CMEO 0%) and with CMEO at 0.5%, 0.75% and 1%, the best growth performance was seen for those fish fed with the CMEO 0.5% diet. No significant differences were seen for the haematological parameters and blood cell indices versus CMEO 0%. Serum glucose, triglycerides, cholesterol and glutamic pyruvic transaminase were significantly reduced in the fingerlings fed with the CMEO 0.5% diet versus CMEO 0%. Thus, CMEO oil as a 0.5% dietary supplement can be used to improve the growth performance and health status of the common carp without any adverse effects seen.

Gossypol is a substance found in the cottonseed. Recently in Iraq and in other countries the cottonseedwas used as a concentrate for fish and other animals without awareness of the risk. The present study isdesigned to shed the light on the deleterious effect of gossypol on some hematological parameters andenzymes of male common carp Cyprinus carpio l.. Oral administration of gossypol 20 mg./kg. b.w. forten days was found to be a strong lyses for red blood cell, reduced packed cell volume and increasederythrocyte sedimentation rate and decreased total white blood cell. Furthermore alkalinephosphotase, alinine aminotransferase and aspartate aminotransferase were increased which reflectliver and kidneys damage caused by gossypol coincided with the histopathological changes in whichthere was mainly degeneration as well as inflammatory cells infiltration
