    Abstract

    Fishing vessels using ~10 km long bottom longline operate in the French EEZ of Kerguelen and Crozet and report catches by species along with geographical coordinates. This papers presents a new method to better take into account the information associated to the path of the line instead of only the mid-point as commonly used to calculate catch rates.
