Ria Formosa long-nosed seahorse population down 94%

Published on 08/01/2018

Opposition MPs Teresa Caeiro, Patrícia Fonseca, Álvaro Castello-Branco and João Rebelo have questioned the Government on news reports of the danger of the Ria Formosa seahorse population dying out, considered until recently the largest population of seahorses in the world .

In two questions sent to the Minister of the Environment and to the Minister of National Defence, the MPs demanded to know what enforcement actions have been carried out and how often the Maritime Police have been nabbing illegal seahorse fishermen.

Secondly, the MPs ask what environmental control and management plan is in operation specifically to help the seahorse population, including measures for the conservation and restoration of their habitat in the Ria Formosa to ensure the sustainability of the species.

Under the heading “The seahorse at risk of disappearing,” Correio da Manhã published a news item that stated that “what has become the largest population of seahorses of the World is almost completely decimated. By mid-2000, it was estimated that there were around two million in the Ria Formosa estuary and now, according to the latest studies, 94% of long-nosed seahorses and 73% of short-nosed seahorses have disappeared.”

The figures have been corroborated by researchers from the Centre for Marine Sciences at the University of Algarve.

The news report added that the Faro and Olhão Maritime Police are fighting the illegal capture of seahorses with regular patrols and have made several arrests with fines that in theory, could reach €40,000.

The seahorse is captures, dried and sold to intermediaries supplying the Asian market.

The MPs added that the seahorse acts as an environmental indicator and that its depopulation has an impact can have catastrophic consequences throughout the marine ecosystem.

Project Seahorse, ‘a marine conservation group dedicated to securing a world where marine ecosystems are healthy and well-managed,’ has been researching the population of seahorses for over 12 years via a number of PhD projects and acts as the IUCN Species Survival Commission Specialist Group for Seahorses and other species.

The Project Seahorse managers “are both aware and concerned about the dramatic decrease in seahorse populations over the last decade which has been attributed to habitat loss and human related activities within the Ria Formosa,” e.g. the illegal capture of seahorses.

MPs, environmentalists and the general public would like to hear what the government is doing in the light of this dramatic decline in seahorse population levels in the Ria Formosa.
