Bottom longline surveys of elasmobranchs and teleosts in Coastal Alabama, Mississippi, and the Chandeleur Islands in 2017

Dataset extent

Abstract

Catch and individual measurements from all organisms captured on bottom longline surveys in Coastal Alabama, Mississippi, and the Chandeleur Islands in 2017. 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 on six days between April 7 and April 21, 2017. All organisms were enumerated by species, measured (to the nearest mm fork length), weighed (to the nearest kg), tagged, and released.

Purpose

Our purpose was to assess the species diversity of apex and mesopredators across the Northern Gulf of Mexico and measure any shifts in community assemblages, as well as note any residual effects from the Deepwater Horizon oil spill.
