The greatest tragedy in the Goliath Grouper story is that the institutions in charge of managing its survival can’t see beyond the “fishery” label.

Open Letter to the Florida Fish and Wildlife Conservation Commission (FWC)

February 2, 2017

FWC Commissioners,

Recently, at a Facebook post, FWC made the following statement: “all wild animals deserve respect and space”. Once again, FWC is holding a meeting to discuss whether a wild animal deserves respect and space. On February 8, 2017, FWC will review the status of Goliath Grouper and “management strategies that could be considered in the future that could potentially provide additional information about this species in Florida”. This is code for discussing a potential reopening of the fishery. The same discussion was held in 2007, 2009, 2011 and 2014, with various killing proposals. All proposals were finally rejected in view of the scientific evidence and stakeholder opposition. As a reminder, Goliath Groupers live in the slow lane, with juvenile females entering the adult population by 8 years old (close to the age of menarche in girls or age of first menstruation), and they have a maximum lifespan beyond 40 years (perhaps 60 to 100 years old). For such a long lived fish, a 2 to 3-year difference between assessments to reopen the fishery is absurd.

The greatest tragedy in the Goliath Grouper story is that the institutions in charge of managing its survival can’t see beyond the “fishery” label.

Fish are wildlife. They are not commodities. They are an integral part of marine and freshwater ecosystems. They are not numbers in stock assessment models but animals with complex life histories. We kill fish to eat them. Sometimes we kill so many of them they go extinct, or almost. We killed so many Goliath Groupers once in Florida and the Southeastern USA they reached commercial extinction. This is the reason for the 1990 state and federal moratorium on harvest.

It takes 27 years to grow a 27 year old Goliath Grouper. The obvious gets lost in our current economy ruled by quarterly profits. Such short-term approach permeates through FWC when you are pressured by the fishing lobby to “do something” about the Goliaths, and that “something” is usually understood by “we want to kill them again”, with the labels of “scientific take”, “culling”, “selected take” and various creative language.

The reason most frequently used to reopen a recreational take of Goliath Grouper is the perception that Goliath Groupers eat everything and are responsible for declining fish and lobster stocks. This is an urban legend with no connection to reality. Research done by myself and others shows that overfishing, not Goliath Groupers, is the reason for declining fish and lobster stocks. In fact, Goliath Groupers eat predators of juvenile lobsters, allowing more lobsters to grow to legal size and making more lobsters available to fishers.

Sometimes the need to “thin the herd” is also used as a reason to reopen the Goliath Grouper fishery. However, the thinning is already happening because Goliaths are killed for several reasons, from the mundane (red tides, poaching) to the exotic (death by nuclear reactor). In 2005, extensive red tides killed close to 100 adult Goliath Groupers in the west coast of Florida. This is a recovery setback because we lost individuals capable of producing the next generations. In the 2009 and 2010 winters, extreme cold water temperatures in Florida killed 90 % of juvenile Goliath Groupers living in mangrove shorelines. This is another setback because we lost fish that were unable to reproduce at all, and therefore contributed nothing to the recovery. In August 2011, over 75 adult Goliath Groupers were killed at the St. Lucie nuclear power plant in Fort Pierce, Florida. The fish were trapped in the plant’s water intake canal. This is a major manmade disaster. FWC and NOAA promised improved contingency measures, but the intake canal and the danger remains.

Poaching of Goliath Grouper exists. FWC enforcement is aware of it. We also know there’s targeted catch and release, even when it represents a violation of the ongoing moratorium, plus there is “possession” in the sense that Goliaths are held out of the water to take pictures, which eventually show in social media, in sport fishing magazines, etc. (another violation of the moratorium). We don’t know how many of the “released” Goliaths actually survive (after fighting on the line and posing for pictures while drowning).

Lastly, some fishers say they want to kill Goliath Groupers to eat them. Goliaths have such high levels of methyl mercury that they are deemed unsafe for human consumption.

What economic benefits can we get from Goliath Groupers? I’m aware these days species must pay forward for their own protection and Goliath Groupers have been doing so quietly and in abundance. Although the species has not recovered to pre-exploitation levels, enough Goliath Groupers are showing up at a few spawning aggregation sites that their presence, and the SCUBA divers that come to visit them, bring a much needed lifesaver to small businesses in Florida, between late August and early October, just when transition between the summer and winter seasons will leave these businesses in the doldrums. Here, the whole is greater than the sum of its parts, because every individual Goliath Grouper contributes to the underwater spectacle of a spawning aggregation, which is what the scuba divers pay to see. In this sense, every single Goliath Grouper is precious and has value by itself, and brings added value when forming a spawning aggregation.

A live Goliath Grouper is more valuable than a dead one. And living Goliaths will keep forming spawning aggregations and contributing to the Florida economy for as long as they live.

Killing Goliath Groupers is not supported by scientific research. Continuing their protection ensures the livelihoods of Florida businesses and workers because SCUBA divers from all over Florida, the USA and the world come here to see these spectacular gentle giants. Florida is now the only place in the world where we can find Goliath Groupers reliably in any significant numbers.

For all these reasons, I urge the FWC Commission to grant Goliath Groupers wildlife status and designate this species as a non-consumptive fish for ecotourism. Scientists from FWC and other institutions can work together to manage the species for conservation.

Sincerely

Sarah FriasTorres, Ph.D.
