Ya est\u00e1n disponibles los resultados preliminares del proyecto de investigaci\u00f3n \"Desarrollo y uso de artes de pesca con nasas adaptadas a las condiciones de la zona costera polaca del Mar B\u00e1ltico\". El principal objetivo de la investigaci\u00f3n era reducir el impacto de la pesca en el medio marino, lo que incluye evitar y reducir, en la medida de lo posible, las capturas no deseadas. Para ello, el proyecto llev\u00f3 a cabo una investigaci\u00f3n pionera en torno al uso de artes de pesca alternativas: Las nasas para peces del B\u00e1ltico.<\/span><\/p>\n

La investigaci\u00f3n corri\u00f3 a cargo de un consorcio formado por una organizaci\u00f3n de productores -el Grupo Dar\u0142owska de Productores Pesqueros y Armadores- y un socio cient\u00edfico -la Universidad Tecnol\u00f3gica de Pomerania Occidental, en Szczecin-. El estudio se realiz\u00f3 tanto sobre la composici\u00f3n por especies y tallas de los peces presentes en las capturas como sobre la eficacia de la protecci\u00f3n de las capturas frente a la interferencia de las focas. El estudio fue realizado por un equipo cient\u00edfico junto con pescadores artesanales de la zona costera del B\u00e1ltico polaco. La pesca de investigaci\u00f3n corri\u00f3 a cargo de 21 embarcaciones del puerto pesquero de Dar\u0142owo. Los pescadores realizaron cruceros de investigaci\u00f3n entre julio y finales de noviembre de 2023. La pesca en el marco del proyecto se llev\u00f3 a cabo sobre la base de un permiso de pesca de investigaci\u00f3n expedido por el Ministerio polaco de Agricultura y Desarrollo Rural. Como parte de la ejecuci\u00f3n de la operaci\u00f3n, se realizaron 30 cruceros con cada uno de los buques pesqueros. El crucero de investigaci\u00f3n consisti\u00f3 en la pesca con redes de enmalle pasivas o anzuelos y las probadas nasas para peces del B\u00e1ltico. En la captura, el pescador colocaba cebo en la jaula y la dejaba fuera durante al menos 16 h. Adem\u00e1s, se calaba un juego de redes de enmalle comerciales o hasta 1.000 anzuelos. Durante la pesca, el pescador registraba los datos de las capturas y rellenaba debidamente la hoja de capturas del estudio sobre las nasas b\u00e1lticas (que inclu\u00eda la marca del pescador, el n\u00famero y la ubicaci\u00f3n de las nasas caladas, las caracter\u00edsticas del arte de comparaci\u00f3n -tipo de arte, longitud del calado, luz de malla-, el tiempo de pesca, la profundidad de la pesquer\u00eda, el tipo de fondo, las condiciones meteorol\u00f3gicas -estado del mar, fuerza y direcci\u00f3n del viento, temperatura del agua-, el n\u00famero de peces, las especies de peces capturados y su peso dentro de cada especie). Adem\u00e1s, se llevaron a cabo observaciones y documentaci\u00f3n subacu\u00e1tica de las nasas de pescado expuestas. Cada vez que se realizaba un crucero, el pescador entregaba en puerto una hoja de capturas del estudio Baltic Fish Pots cumplimentada, as\u00ed como los peces capturados con las artes de pesca (redes de enmalle o anzuelos y Baltic Fish Pots). Se midieron (LT) y pesaron (W) todos los peces capturados con nasas y, adem\u00e1s, el bacalao capturado con redes de enmalle o anzuelos.\u00a0<\/span><\/p>\n

La investigaci\u00f3n realizada permiti\u00f3 extraer las siguientes conclusiones:<\/span><\/p>\n

    \n
  1. Tres especies de peces dominaban la pesca en jaulas: el bacalao (Gadus morhua<\/i>), la platija europea (Platichthys flesus<\/i>) y la gallina diab\u00f3lica (Myoxocephalus scorpius<\/i>).<\/li>\n
  2. Los peces de las nasas estaban vivos y en buen estado.<\/span><\/li>\n
  3. Capturas \u00fanicas de otras especies de peces, como la caballa (<\/span>Scomber scombrus<\/span><\/i>), parr (<\/span>Alosa fallax<\/span><\/i>) y la perca (<\/span>Perca fluviatilis<\/span><\/i>).<\/span><\/li>\n
  4. En ocasiones se observ\u00f3 la presencia simult\u00e1nea de dos especies de peces en las nasas; bacalao y platija; bacalao y gallina diablo.<\/li>\n
  5. Peri\u00f3dicamente se observa una presencia significativa de medusas (<\/span>Aurelia aurita<\/span><\/i>) en las nasas para peces, momento en el que no se detectaron peces.<\/span><\/li>\n
  6. Focas grises (<\/span>Halichoerus grypus<\/span><\/i>) y mostraron gran inter\u00e9s por la pesca de investigaci\u00f3n que se estaba llevando a cabo. Durante la pesca se observaron da\u00f1os en las redes de enmalle y peces atrapados. No se observaron da\u00f1os en las nasas por parte de las focas grises durante la pesca, pero s\u00ed dos casos de focas enredadas en las redes de enmalle. Se puede concluir que las nasas cumplen los objetivos originales y son resistentes y respetuosas con las focas.<\/span><\/li>\n
  7. Como resultado del estudio, se identific\u00f3 la necesidad de llevar a cabo nuevas investigaciones, en otras \u00e1reas de la zona costera del B\u00e1ltico polaco y durante un per\u00edodo de tiempo m\u00e1s largo, teniendo en cuenta las modificaciones previstas del dise\u00f1o de las jaulas Baltic Fish Pots.<\/span><\/li>\n<\/ol>\n
