Big fish, big trouble
November 11th, 2009As their name suggests, Goliath Groupers are really very big indeed. The largest known have been around 2.5m long, or 8 feet.
They are undeniably fully-fledged members of the marine megafauna.
But these big fish are in big trouble and they need your help.

Because it’s become more and more difficult to spot one of these giants, the fish formerly known as jewfish. Being so very huge made them an irresistible target for fishers. Over the last few decades goliath groupers have been fished so heavily from their reefy and rocky homes on both sides of the Atlantic, in the Caribbean and the eastern reaches of the Pacific Ocean, that they are now labelled as being Critically Endangered.
In days gone by, a common place to spot a goliath grouper was strung up on a quayside alongside a grinning recreational fisher. So many goliath groupers were caught by sport and commercial fishers that their populations became economically extinct: it made no sense to try and catch them if you wanted to make money.

Good news is that since the 1990 it’s been illegal to catch goliath groupers in US waters. And a fishing ban on them has been in place across the Caribbean since 1993. As a result, populations of these enormous fish have been slowly recovering.
The problem is they have apparently been recovering a bit too well for some people’s liking. There is growing pressure to lift the fishing ban in Florida, one of the only places where scuba divers have a good chance of meeting these kings of the reef. Do we really want to relive a time when killing such magnificent fish was all the rage? Couldn’t we move on from that?
In early December the Florida Fish and Wildlife Conservation Commission will decide on whether to stick to the goliath grouper fishing ban or open these beasts up once again to human exploitation.
The Floridian scuba diving and conservation community are lobbying politicians hard in the hope they will hear a unified and loud voice of reason. An online petition to keep the fishing ban is gathering support and they hope to reach at least 1000 signatures.
So, do your bit and sign up. Because wouldn’t it be a crying shame if these spectacular beasts were once again allowed to be caught to make a bit of money or just for the fun of it.

It’s been well proven that big fish like the goliath grouper are far more vulnerable to extinction than smaller fish. In a twist of nature, it’s the bigger animals that grow more slowly and take longer to reach maturity (5 or 6 years for goliath groupers). So, if someone asks you to take a guess at which species are most at risk, whether they live in the sea, on land, or in freshwater, all you need do is pick out the biggest ones and you won’t go wrong.
In detail:
- Goliath groupers or jewfish (Epinephelus itajara) can live for nearly 40 years if we let them.
- They commonly grow to 1.5m from head to tail.
- Young goliath groupers live in mangrove forests, giving us yet another vital reason to care about and protect these habitats that are so often overlooked and cleared away.
Thanks for this wonderful post. A number of scientists, divers and conservationists will be at the Florida Fish & Wildlife meeting tomorrow, and will speak up in support of keeping the Goliath Groupers protected. At the last FWC commission meeting in September, the Commissioners talked about all the letters and phone calls they’ve received about the goliath groupers being aggressive towards divers and eating all the lobsters. This is all crap obviously. The groupers are extremely shy, and will hide inside the nearest hole when you approach too closely. They also have a burrowing behavior that actually creates habitat for smaller grouper species, lobsters and other species. In September I dived on wreck where over 50 Goliaths were gathering to spawn. There were many, many lobsters there. On the other hand, there are thousands and thousands of recreational divers taking up to six lobsters per day during lobster seasons, plus the commercial fishermen!
Thanks again!
You’re welcome Mary. I know that at least a few of my readers went and signed the petition.
I have my fingers crossed that the right decision is made for these amazing fish.
