An economically important species of Citharus linguatula was investigated in the Sea Marmara (Eastern Mediterranean, Turkey). Length-weight relationships, growth parameters, reproductive time, and first sexual maturity length were determined. A total 236 individuals analyzed, weight varied from 7.5 to 26.5 cm TL (17.11±3.62 cm) 2.67 180.81 g (44.07±1.84 g), respectively. The length-weight relat...

This article aims to explore the effectiveness of materiality principle (MP) within Integrated Reporting (IR) by applying General Systems Theory (GST) Ludwig von Bertalanffy. GST, its holistic approach, can be used identify main sub-systems in which regulation IR articulated and relationships between themselves, make MP effective, thereby improving quality regulation. While much research has an...

Abstract Despite the high commercial value of striped seabream Lithognathus mormyrus (Linnaeus, 1758) in Gulf Tunis, biological data on its age, growth and exploitation rate are lacking. With aim estimating parameters, 516 individuals, ranging from 6–27.5 cm total length 3.5–293.5 g weight, were collected artisanal fishing fleet between February 2014 July 2016. The somatic presented a positive ...

the age and growth of the persian sturgeon, acipenser persicus, obtained from the iranian coastal waters of the caspian sea, were studied through analysis of the pectoral fin ray section from 180 specimens, ranging in fork length (fl) from 66 to 203 cm. the specimens were obtained from commercial fisheries between october 2008 and june 2010. interpretation of growth bands in the pectoral fin ra...

the populations of wild carp (cyprinus carpio carpio), as a commercially valuable species in the southeast iranian waters of the caspian sea, have been severely declined during last three decades, but there is no comprehensive research available on the biology of this species in this area. the age, growth and reproductive aspects of samples collected during 2009-2010 fishing season were measure...
