Differences in proximate lipid composition, heavy metals, and mineral contents in bogue (Boops boops, Linnaueus, 1758) captured far away and directly at sea bass and sea bream cage farms

Differences in proximate lipid composition, heavy metals, and mineral contents in bogue (Boops... The objective of this study was to investigate the differences in proximate lipid composition, heavy metals, and mineral contents between bogue (Boops boops, Linnaeus, 1758) captured directly around and near a cage fish farm and those captured far away from it (“wild”). Wild fish were obtained from the fishery of the Aegean Sea and Northeastern Mediterranean. Fish were also caught at a distance of at least 100 meters away from the net cages using a commercial trammel set net. The fish captured near cages were taken at farms cultivating mainly sea bass and sea bream. Samples were taken in March 2016 to determine crude lipid content, moisture, and ash amounts. There were some differences between wild fish and near farm captured fish for both genders. Crude lipid contents of female wild fish and near farm captured fish were found to be higher than those in males (p < .05). The moisture contents of the males near the farms were higher than those in females. Results showed that the predominant macro minerals were potassium in females and males for both capture locations (near and far away from farms: range of 1070–1205 mg/kg). The near farm captured fish had a higher heavy metal content than those captured further away. This may be the result of environmental influences caused by the farm operations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

The objective of this study was to investigate the differences in proximate lipid composition, heavy metals, and mineral contents between bogue (Boops boops, Linnaeus, 1758) captured directly around and near a cage fish farm and those captured far away from it (“wild”). Wild fish were obtained from the fishery of the Aegean Sea and Northeastern Mediterranean. Fish were also caught at a distance of at least 100 meters away from the net cages using a commercial trammel set net. The fish captured near cages were taken at farms cultivating mainly sea bass and sea bream. Samples were taken in March 2016 to determine crude lipid content, moisture, and ash amounts. There were some differences between wild fish and near farm captured fish for both genders. Crude lipid contents of female wild fish and near farm captured fish were found to be higher than those in males (p < .05). The moisture contents of the males near the farms were higher than those in females. Results showed that the predominant macro minerals were potassium in females and males for both capture locations (near and far away from farms: range of 1070–1205 mg/kg). The near farm captured fish had a higher heavy metal content than those captured further away. This may be the result of environmental influences caused by the farm operations.
