          Abstract

          The Olrog's Gull (Larus atlanticus) is an endemic species of the Atlantic coasts of southern South America and is considered vulnerable to extinction. Olrog's Gull individuals of different age classes die in Mar Chiquita coastal lagoon, Buenos Aires Province, while interacting with sport fisheries. Due to its restricted distributional range and their scarce populations, a slight increase in mortality rates may easily affect populations of this species by altering survival rates of all or particular age classes. The evaluation of this impact and the proposal of mitigation measures (also comprising an educational component) are essential for the conservation of this species in non-breeding grounds.

          La Gaviota Cangrejera (Larus atlanticus) es una especie endémica de la costa atlántica del sur de América del Sur y posee un status de Vulnerable. En la laguna costera de Mar Chiquita, provincia de Buenos Aires, se hallaron individuos de diferentes clases de edades muertos a causa de la ingesta de artes de pesca deportiva. Debido al reducido número poblacional y de colonias reproductivas de la especie, pequeños incrementos de mortalidad por causas no naturales podrían tener efectos importantes sobre la tasa de supervivencia de una o todas las clases de edad. Es indispensable evaluar este impacto y proponer medidas de mitigación (incluyendo componentes educativos) para la conservación de esta especie en los sitios de invernada.
