Recent research provides evidence that parasites and pathogens may impact a commercially important species which generates $500 million in income for fishers and close to $1 billion in export revenue each year.<\/strong> <\/p>\n

As global climate change and warmer water temperature can facilitate the spread of various pathogens in the ocean, increasing attention must be given to the health status of marine organisms, especially those of ecological and commercial interest. Nicole Atherley, a final year PhD student at Ross University School of Veterinary Medicine (St Kitts & Nevis) and fellow of the Caribaea Initiative (a Caribbean-based conservation NGO), have recently come with new and original results about the presence of pathogens in the Caribbean spiny lobster, Panulirus argus <\/em>in the Eastern Caribbean. The species is considered a delicacy the world over, and, as such, supports an important and broad economy in artisanal fishing, from North Carolina (USA) to Brazil and throughout the Caribbean basin. However, although populations have declined throughout its range, little is known about its diseases and pathogens.<\/p>\n

In two recently published scientific articles, Nicole Atherley and her coworkers at Ross University reported the infection of Caribbean spiny lobsters with various parasites and pathogens, including bacteria, microsporidians (parasitic fungi), and worms. In particular, about 90% of fecund female lobsters examined around St Kitts were infected with at least one of two species of parasitic Nemertean worms (including a newly described one) that feed on the eggs of their crustacean hosts. Infection with microsporidians and bacteria, on the other hand, were associated with muscle and tail fan necrosis that can seriously affect the commercial value of lobsters. According to Professor Frank C\u00e9zilly, founding president of Caribaea Initiative, these findings are of high importance: \u00ab It is known that climate change enhances disease processes in crustaceans. Both increasing\u00a0 temperature\u00a0 and ocean acidification\u00a0 act\u00a0 as\u00a0 stressors\u00a0 that\u00a0 negatively\u00a0 affect\u00a0 the ability of\u00a0 ecologically\u00a0 and\u00a0 commercially\u00a0 important\u00a0 species to resist infectious diseases and parasites. The results obtained by Nicole Atherley during her PhD call for further research\u00a0 and a closer monitoring of lobster populations in the Caribbean region in relation to climate change \u00bb. Indeed, in line with Caribaea Initiative’s mission, capacity building in marine disease ecology appears to be of prime importance in the insular Caribbean as the region heavily depends on ocean resources for livelihood or tourism.\u00a0 As a native from Barbados, Nicole Atherley is ready for the challenge.<\/p>\n
