A marine biologist has cautioned that the mass deaths of starfish along the United States west coast in recent months could also occur in the Caribbean region because of climate change, threatening the vital fishing sector.
Since June 2013, scientists began noticing that starfish, which they say function as keystone species in the marine ecosystem, have been mysteriously dying by the millions.

“The cause of the starfish die-off which is taking place in the Pacific Ocean is not known at this time but it could turn out to be from a number of factors including climate change,” John Mussington told IPS.
“If it turns out that climate change factors such as ocean warming are indeed implicated in the starfish die-off, then there is the possibility that the same thing could happen in the Atlantic and affect Caribbean species.

Starfish play a key role in marine ecosystems. They eat mussels, barnacles, snails, mollusks and other smaller sea life so their health is considered a measure of marine life on the whole in a given area. Starfish are in turn eaten by shorebirds, gulls, and sometimes sea otters.

Habitat degradation, specifically of coral reefs, has been cited by numerous studies as the primary cause of ongoing fish declines of Caribbean fish populations.
Caribbean coral reefs have experienced drastic losses in the past several decades. Fish use the structure of corals for shelter and they also contribute to coastal protection.
Established research has predicted that the communities located in coastal areas, as well as national economies in the general Caribbean region, are likely to sustain substantial economic losses should the current trends in coral reef degradation and destruction continue.
It has been estimated that fisheries associated with coral reef in the Caribbean region are responsible for generating net annual revenues, which have been valued at or above approximately 837 million Eastern Caribbean dollars, or about 310 million U.S. dollars.

The fisheries sector in the CARICOM Region is an important source of livelihoods and sustenance. The local population is highly dependent on this resource for economic and social development. This resource also contributes significantly to food security, poverty alleviation, employment, foreign exchange earnings, development and stability of rural and coastal communities, culture, recreation and tourism.
The subsector provides direct employment for more than 120,000 fishers and indirect employment opportunities for thousands of others – particularly women – in processing, marketing, boat-building, net-making and other support services.
But the coordinator for the United Nations Environmental Programme’s Caribbean Regional Coordinating Unit-Caribbean Environment Programme, Nelson Andrade Colmenares, told IPS the vital sector is being threatened by climate change.
“The Caribbean Sea, home to a vibrant ecosystem benefitting fisherfolk, the tourism industry and the region’s people alike is currently threatened,” he said, adding that “over harvesting of fisheries, climate change and pollution from sewage, agricultural runoff and industrial effluent has led to 75 percent of coral reefs in the region being labeled as at risk.”
. . .
Acting permanent secretary in Dominica’s fisheries ministry, Harold Guiste agrees, explaining that the future of the Caribbean’s conch and lobster fisheries remains under threat despite regional efforts to protect it.
Guiste blames the problem of overfishing squarely on nations outside the Caribbean that trawl the region’s seas illegally.
“Globally we have noticed a rush to fish accompanied by a lack of responsible behaviour in the fishing sector,” he told IPS. “This type of hooligan behaviour has resulted in severe decline in some major fisheries of the world and collapse in some others.”

While admitting that “some factors are out of our control as it relates to mitigating against global warming”, Mussington said both developing and developed countries need to do more.
“We need to do things which will discontinue the rise in global temperatures and those things that need to happen have to do with less use of fossil fuels and modification of certain things that countries do,” he told IPS.
In fact, the persons who are going to be suffering most – the people living in these Small Island Developing States – we are not the ones ultimately responsible in large measure for the problems we are having now, the developed countries are.”
“So far the developed countries have been very resistant to implementing those policies and changes that need to happen,” Mussington added.
In the end, he said the annual Conference of the Parties (COP) negotiations should not be simply about the smaller countries winning.
“It’s a fight that the world has to win if it is to survive because if the small states don’t win, it means that the globe as a whole does not win, which means that Planet Earth will lose out and the human race on planet earth might very well face total extinction,” warned Mussington.
“That’s what’s facing us. The globe will become unlivable,” he added.
