Fishing is definitely a popular hobby here in the Cayman Islands but some species are being over-fished.
Underwater photographer Cathy Church says the targeting of the grouper is changing the marine eco-system. By allowing fish who feed on the reefs to continue eating, without being eaten, resulting into dead reefs.
“There is a little fish called the dusky damselfish, that nips at the corals and nips on the sponges and kills them off in order to grow its algae garden, the main predator on that dusky damselfish is the grouper, the grouper is the guy that goes in there and kills them and eats them and helps keep their numbers in check. We need the dusky damsels we need the groupers, the two of them make a nice even balance on the reef,” said underwater photographer, Cathy Church
Mrs. Church suggests that the protected marine areas should be expanded, giving groupers a chance to reproduce for they are being fished out faster than they can reproduce.
