Using fisher’s knowledge to estimate catch and effort in the large-scale octopus fishery on the eastern Campeche Bank (Mexico, NW Atlantic)

The Mayan octopus (Octopus maya) and the American (O. americanus) are two species that support fishery on Campeche Bank. large-scale fleet catches both species. However, landings recorded as in official statistics, this causes a problem for management of fishery. Bank was studied using model based data from interviews with skippers. A total 180 valid were conducted base ports Progreso Yucalpeten (Yucatan), representing 51.1% skippers 2019. This information used first time to estimate catch per unit effort (CPUE) each mean CPUE ranged between 50 500 kg day-1, minimums 10 day-1. estimated potential 5069 3456 t year O. maya 4113 2805 americanus. relationship showed significant correlation (rxy=0.898). average 20% lower than origin discrepancy is discussed.
