The cobia, Rachycentron canadum, a species of marine fish, has been increasingly used in aquaculture worldwide. It is the only member of the family Rachycentridae (Perciformes) showing wide geographic distribution and phylogenetic patterns still not fully understood. In this study, the species was cytogenetically analyzed by different methodologies, including Ag-NOR and chromomycin A(3) (CMA(3)...

This study aimed to investigate otolith in Rachycentron canadum in the Persian Gulf and Oman Sea. Sampling lasted from March 2014 to April 2015 in Khouzestan to Sistan and Baloochestan waters. During this period 30 specimens of R. canadum were caught and studied. Trawling time was 2-2½ hours and trawling depth was considered as 10-100 m daily. All the fish were identified and their otolith was ...

Cobia, Rachycentron canadum, is the only species in family of Rachycentridae. Cobia typically characterized as having 26–33 dorsal-fin rays. However, an investigation specimens collected from Western Visayas waters revealed a wider variation ray count than previously reported, with some 35–36 Suspecting possible cryptic species, we compared mitochondrial cytochrome oxidase subunit 1 (COI) seque...

Since 1995, the Virginia Game Fish Tagging Program (VGFTP) has collected data for recreationally important marine fishes in cooperation with skilled volunteers. These trained anglers tagged more than 380,000 since 1995 and contributed regarding fish movement site fidelity patterns of species captured released Chesapeake Bay Atlantic coastal waters. Over time, VGFTP become an source fishery mana...

The cobia is the only representative of the Rachycentridae family and, because of its zootechnical qualities, production of this fish has been implemented in several countries, such as the United States, Mexico and Brazil. Tuxophorus caligodes is a widespread parasite of marine fish worldwide. For the present report, 15 juvenile cobias were collected from net cages on a fish farm in Ilhabela, s...
