El elefante marino del sur es el pinnípedo más grande del mundo; tiene un comportamiento de dispersión y presenta largos movimientos migratorios en los océanos en busca de presas en las áreas de alimentación y zonas de hábitat idóneo. En este estudio recopilamos y analizamos los registros de su presencia en Ecuador entre 1998 y 2020. Realizamos entrevistas, revisiones bibliográficas y visitas a ciertos sitios de registro. Registramos 15 individuos en las provincias de Los Ríos, Guayas, Galápagos y Esmeraldas. La presencia de estos individuos probablemente está relacionada con anomalías térmicas oceánicas causadas por eventos de El Niño-Oscilación del Sur y La Niña, que bien pueden haber modificado el movimiento y dispersión de esta especie fuera de su rango de distribución normal. Los avistamientos de M. leonina en Ecuador corresponden a individuos en reposo y todos abandonaron sus sitios de descanso días después de su arribo. Solo en una ocasión, un macho subadulto reportado en jul...

The interaction of small cetaceans with fishing gear is considered a major conservation issue worldwide. Between April and September 2009 a study was conducted to assess the level of bycatch in artisanal fisheries of Puerto Lopez, Salango and Machalilla, on the central coast of Ecuador. For this purpose 185 trips of boats using gillnets and purse seine nets as fishing gear were monitored. During the study, seven cetaceans of four different species were caught: two bottlenose dolphins Tursiops truncatus (28.57%), one dwarf sperm whale Kogia sima (14.28%), two Risso's dolphins Grampus griseus (28.57%) and two spotted dolphins Stenella attenuata (28.57%). All cases occurred in gillnets with 5-inches wide mesh. The estimated average mortality rate was 0.07 dolphins/day. August was the month with the highest bycatch rate (0.18 dolphins/day).These results indicate an increase of the bycatch rate compared with previous studies. Fishermen showed interest and willingness to collaborate o...

A B S T R A C T Bycatch of marine fauna by small-scale (artisanal) fisheries is an important anthropogenic mortality source to several species of cetaceans, including humpback whales and odontocetes, in Ecuador's marine waters. Long-term monitoring actions and varied conservation efforts have been conducted by non-governmental organizations along the Ecuadorian coast, pointing toward the need for a concerted mitigation plan and actions to hamper cetaceans' bycatch. Nevertheless, little has currently been done by the government and regional authorities to address marine mammal interactions with fisheries in eastern Pacific Ocean artisanal fisheries. This study provides a review of Ecuador's current status concerning cetacean bycatch, and explores the strengths and weaknesses of past and current programs aiming to tackle the challenges of bycatch mitigation. To bolster our appraisal of the policies, a synthesis of fishers' perceptions of the bycatch problem is presented in concert with recommendations for fostering fishing community-based conservation practices integrated with policies to mitigate cetacean bycatch. Our appraisal, based upon the existing literature, indicates a situation of increasing urgency. Taking into consideration the fishers' perceptions and attitudes, fisheries governance in Ecuador should draw inspiration from a truly bottom-up, participatory framework based on stakeholder engagement processes; if it is based on a top-down, regulatory approach, it is less likely to succeed. To carry out this process, a community-based conservation programs to provide conditions for empowering fishing communities is recommend. This would serve as an initial governance framework for fishery policy for conserving marine mammals while maximizing the economic benefits from sustainable small-scale fisheries in Ecuador.
