Expanding marine protected areas by 5% could boost fish yields by 20% – but there's a catch

Expanding marine protected areas by 5% could boost fish yields by 20% – but there's a catch | Biodiversité | Scoop.it

Marine protected areas, or MPAs as they’re more commonly called, are very simple. Areas of the sea are set aside where certain activities – usually fishing – are banned or restricted. Ideally, these MPAs might be placed around particularly vibrant habitats that support lots of different species, like seagrass beds or coral reefs. By preventing fishing gear such as towed seabed trawls from sweeping through these environments, the hope is that marine life will be allowed to recover.

When used well, they can be very effective.

Une étude alerte sur la pollution sonore qui fragilise la santé des poissons

Une étude alerte sur la pollution sonore qui fragilise la santé des poissons | Biodiversité | Scoop.it

La pollution sonore est source de stress, de perte d’audition ou encore d’immunité réduite pour les poissons. Sonars, forages ou moteurs, sont autant de sources de « stress, perte d’audition, changements de comportement et d’immunité réduite » pour les populations de poissons, rappelle l’étude menée par des chercheurs de l’Université de Cardiff. Leur contribution, publiée mercredi dans la revue Royal Society Open Science, porte sur l’impact de la pollution sonore sur la résistance à des maladies parasitaires, un fléau de la pisciculture.
