The mesopelagic zone provides a critical link between surface waters and the abyss: what happens here will affect food supply and climate resilience throughout the ocean. Spanning the water column between roughly 200 and 1,000 meters, it comprises only 20% of the ocean by volume yet is home to 50-90% of the planet’s fish biomass.| IUCN World Conservation Congress
