Jamaica: Invasive Lionfish Go From Predator to Prey

'The situation in Jamaica is urgent,' said Nelsa English, national coordinator for the Jamaican component of a Caribbean-wide Invasive Alien Species Project at the National Environment and Planning Agency (NEPA). 'A lack of sufficient natural predators suggests that it (lionfish) could be a potentially significant threat to Jamaica's biodiversity and the ecosystem in general,' she noted.

Jamaica's marine resources are stretched to the breaking point, its reefs overfished and degraded due to environmentally unfriendly fishing practises such as the use of explosives, poisons and fishing nets that are below the legal mesh size.

Scientists agree that many of the reefs have been reduced to coral communities and no longer function as vital ecosystems because their biodiversity is so severely degraded. Some studies suggest that only two percent of some reefs are live coral and the structures themselves are reportedly being eroded faster than they can regenerate.

'Currently our fishing industry survives on the removal of young adults. This practice does not allow for enough fish to mature and reproduce which puts pressure on the fecundity of the ecosystem,' English told IPS.
