Bottom longline surveys of elasmobranchs and teleosts in Coastal Alabama, Mississippi, and the Chandeleur Islands in 2015

Catch and individual measurements from all organisms captured on bottom longline surveys in Coastal Alabama, Mississippi, and the Chandeleur Islands in 2015. Bottom longline gear type consists of 1.85 km (1 nm) of 4 mm monofilament (545 kg test) set with 100 gangions. Gangions are composed of a longline snap and a 15/0 circle hook, baited with Atlantic mackerel (Scomber scombrus). Each gangion is made of 3.66 m of 3 mm (320 kg test) monofilament. Sampling occurs twice per year (spring and fall), three days per season. All organisms were enumerated by species, measured (to the nearest mm fork length), weighed (to the nearest kg), tagged, and released.
