Esfuerzo de pesca aparente<\/b><\/p>\n

Global Fishing Watch analiza los datos AIS recopilados de embarcaciones que nuestra investigaci\u00f3n ha identificado como embarcaciones pesqueras comerciales conocidas o posibles, y aplica un algoritmo de detecci\u00f3n de pesca para determinar la \u00abactividad pesquera aparente\u00bb en funci\u00f3n de los cambios en la velocidad y la direcci\u00f3n de la embarcaci\u00f3n. El algoritmo clasifica cada punto de datos de transmisi\u00f3n AIS para estos barcos como aparentemente pescando o no pescando y muestra la pesca en el mapa de calor de esfuerzo de pesca aparente de Global Fishing Watch.<\/span><\/p>\n

Eventos de pesca<\/b><\/p>\n

Los eventos de pesca utilizan esos puntos de datos como insumo y los resumen en un solo evento para facilitar el an\u00e1lisis. Los eventos de pesca se definen utilizando las siguientes restricciones:<\/span><\/p>\n

    \n
  1. Las posiciones consecutivas identificadas como pesca se agrupan<\/span><\/li>\n
  2. Se separan las posiciones de pesca que aparecen consecutivamente, pero que est\u00e1n separadas por 10 km o m\u00e1s de 2 horas.<\/span><\/li>\n
  3. Los eventos de pesca dentro de 1 hora y 2 km de otro evento de pesca, pero que pueden tener puntos de tr\u00e1nsito intermitentes, se agrupan.<\/span><\/li>\n<\/ol>\n

    Finalmente, el conjunto de datos se restringe eliminando los eventos de pesca que son breves y r\u00e1pidos y, por lo tanto, es menos probable que indiquen un evento de pesca realista. Se eliminan los siguientes eventos de pesca cortos:<\/span><\/p>\n

      \n
    • Eventos de menos de 20 minutos;<\/span><\/li>\n
    • Eventos compuestos por 5 posiciones o menos;<\/span><\/li>\n
    • Eventos que cubren una distancia de menos de 0,5 km (para todos las artes excepto el arte de calamar);<\/span><\/li>\n
    • Eventos que cubren una distancia de menos de 50 m (para arte de calamar) en distancia; y<\/span><\/li>\n
    • Eventos de embarcaciones en movimiento anormalmente r\u00e1pido con una velocidad promedio de 10 nudos por hora o m\u00e1s.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
