Speaking on the science of blue carbon, Miguel Cifuentes, CATIE, Costa Rica, warned of the significant amounts of carbon emissions released through the destruction of coastal habitats, land use conversions and upstream disruptions, saying that coastal ecosystems maintain 75% of all tropical commercial fish species through their role as nurseries.
Campaigners, with the support of marine scientists, have repeatedly tried to persuade countries to agree to an international ban, arguing that the indiscriminate nature of bottom-trawling is causing irreversible damage to coral reefs and slow-growing fish species, which can take decades to reach maturity and are therefore slow to replenish their numbers.
People in moderately developed places that have few amenities such as road, schools and electricity often tend to depend less on fishing, but they also have more access to engine-powered boats, spear guns, and other technologies that can rapidly deplete some fish species, said Joshua Cinner of James Cook University in Australia in the report.
CNN: Beating poverty could save coral reef fish, report says
But the harm they do as a destroyer of habitat, by ripping up corals and sponges, and wrecking the nurseries of fish species that grow very slowly, seems out of proportion to any gain from scraping the ocean floor: one zoologist has compared it to cutting down virgin forests, full of rare species, to collect squirrels.
