According to a study, MPAs or marine protected areas may save coral reefs from the effects of global climate change. It was discovered that the local reef protection worked when researchers of the University of Marine in US studies and spanned the eastern Caribbean across 700 kilometres.
A journal called Science Advances published the recent findings according to which a 62% increase in the density of young corals due to local fisheries management. This improves the ability of the ecosystem to recover from impacts like coral bleaching and hurricanes.
Robert Steneck, a professor at the University of Marine, said that marine protected area could become coral reefs but in contrary studies were not measuring right things at right scales. He added that reducing fishing pressure and increasing the number of seaweed-eating fish is the idea behind MPAs because they will decrease the amount of harmful seaweed due to which baby corals will grow easily.
He said that it is also complicated as a lot of things can affect the numbers of fish. Corals can control algae growth.
According to Peter Mumby, a professor at University of Queensland, Austria, many researchers take shortcuts like using simple data that are widely available to analyse reef protection because filed measurements on coral reefs are time to consume. He added that when they take more detailed measurements, they improve their ability to detect benefits of MPAs on coral reefs.
According to researchers, for the ecosystem and especially for the coral reef there is no panacea of management.
Steneck said that the stresses acting on coral reefs due to atmospheric and climatic change are beyond direct management control. He added that however the measures that local management takes can support the recovery of corals after damaging events and hence improving the overall condition.
The researchers believe that conditions of coral reef will improve in coming days if continuous management measures are provided.
