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...

Optimal concentrations of three anesthetics for use with juvenile cobia (Rachycentron canadum) were determined using time-to-recovery and hematological datasets. Buffered MS-222, clove oil 2-phenoxyethanol (2-PE) examined. Juvenile exposed to each anesthetic at 24 °C. Based on time recovery, optimal doses MS-222 was as 120-mg L−1, that 2-PE, 0.4-mL L−1 and, oil, 5-mL L−1. The response anesthesi...

Total mercury (Hg) concentration was determined in the tissues of 10 pelagic fishes in the northern Gulf of Mexico, and dietary tracers (stable isotopes and fatty acids) were used to evaluate the relationship between Hg and feeding history. Highest Hg levels were observed in blue marlin (Makaira nigricans), carcharhinid sharks (Carcharhinus spp.), and little tunny (Euthynnus alletteratus), rang...
