Identification of scombrids (tunas, mackerels, bonitos, etc.) is difficult when morphological characters are ambiguous or missing, such as with early life history stages or tissues found in the stomachs of predators. The mitochondrial cytochrome c oxidase subunit I (COI) gene region was evaluated as a molecular marker for the specific identification of the 17 members of the family Scombridae common to the western Atlantic Ocean. A 950 base pair region in the COI gene was sequenced from up to 20 individuals of each species, and suites of nucleotide polymorphisms that unambiguously distinguish among these scombrid species were identified. A shorter …

Recent Additions Of Warmwater Fish Species To Chesapeake Bay, Aimee D. Halvorson

During September 2004 and June 2005, the Virginia Institute of Marine Science (VIMS) Juvenile Fish and Blue Crab Trawl Survey collected specimens of three warmwater fish species uncommon to Chesapeake Bay. Captures of Trachinocephalus myop.s (Snakefish), Citharichthys Wfjc/'fj/^.v (Spotted WhifT'). and Mullus auratus {Red Goatfish)are the first substantiated records for these species from Chesapeake Bay. These captures also represent extensions in the documented geographic ranges of Snakefish and Spotted Whiff. Occurrences of multiple species heretofore rarely encountered in Chesapeake Bay warrant further attention in view of concerns regarding climate change and its effect on local marine faunas.
