The giant of the grouper family, the Goliath (formerly called Jewish) has brown or yellow mottling with small black spots on the head and fins, a large mouth with jawbones that extend well past its small eyes, and a rounded tail. The skeletal structure of large Goliath grouper cannot adequately support their weight out of the water without some type of damage.

If a large Goliath is brought on-board a vessel or out of the water, it is likely to sustain some form of internal injury and therefore be considered harvested. Goliath grouper populations declined throughout their range during the 1970s and 1980s due to increased fishing pressure from commercial and recreational fishers and divers.

At their July 2014 meeting in Key Largo, this committee reviewed the most up-to-date scientific information on goliathgrouper and recommended a new stock assessment for this species. As a result, the most recent stock assessment, conducted by the FCC was completed in June 2016 (Sedan 47).

The stock assessment indicates abundance in south Florida has greatly increased since the fishery closed in 1990. However, in the final step of the review process, the assessment was rejected by an independent panel of scientists for use in federal management due to a lack of reliable indicators of abundance outside south Florida.

Goliath are also susceptible to large scale mortality events such as cold temperatures and red tide blooms. When not feeding or spawning, adult Goliath groupers are generally solitary, sedentary and territorial.

Before the goliathgrouper reaches full-size it is preyed upon by barracuda, king mackerel and moray eels, as well as sandbar and hammerhead sharks. Calico crabs make up the majority of their diet, with other invertebrate species and fish filling in the rest.

Reproductive maturity first occurs in fish 5 or 6 years of age (about 36 inches in length) due to their slow growth rate. Males mature at a smaller size (about 42 inches) and slightly younger age than females.

These groups occur at consistent sites such as wrecks, rock ledges and isolated patch reefs during July, August and September. Studies have shown fish may move up to 62 miles (100 km) from inshore reefs to these spawning sites.

In southwest Florida, presumed courtship behavior has been observed during the full moons in August and September. Its range includes the Gulf of Mexico and Florida Keys in the United States, the Bahamas, most of the Caribbean, and most of the Brazilian coast.

Scientists from our Southeast Fisheries Science Center are working to understand the changes that have occurred in coral reef ecosystems following the loss of top predators, such as groupers. The once common Nassau grouper (Epimetheus stratus) and goliathgrouper (E. Tamara) have been so depleted that they are under complete protection from the South Atlantic, Gulf of Mexico, and Caribbean.

From 1997-2005, our researchers collaborated with Florida State University's Institute for Fishery Resource Ecology (Dr. Chris Koenig and Dr. Felicia Coleman) to monitor the status and recovery of goliathgrouper. This goliathgrouper research program investigated juvenile and adult Jewish abundance, distribution and migration patterns; their age and growth; and their habitat utilization.

With the help of Don Maria we have tagged over 1,000 adult Jewish and have observed aggregations of goliathgrouper in both the Gulf of Mexico and more recently, the South Atlantic. Posters created by the Center of Marine Conservation help disseminate information about our project and its requirements, highlighting our tagging study and the morphology of goliathgrouper.

Given that these groupers were afforded protected status, researchers worked to utilize and develop novel non-lethal techniques to procure and analyze biological samples for life history information. These casualties, resulting from red tide, gave our biologists a unique opportunity to collect a multitude of biological samples, without having to sacrifice healthy animals.

From these decomposing carcasses, biologists were able to record length for use in an age/length relationship, and were able to extract monoliths and remove dorsal spines and rays for comparison of hard parts in age and growth analysis. Tissue samples were also removed and sent to the Florida Marine Research Institute, so they could evaluate the level of red tide toxin.

The sampling trip gave these biologists an opportunity to educate the curious beach goers about red tide and goliathgrouper (a few of which had been misidentified as baby manatees). Attempts to evaluate the data needed to assess the status of these depleted stocks and develop rebuilding plans present unique challenges.

In 2010, the Florida Fish and Wildlife Conservation Commission and NOAA Fisheries convened a benchmark goliathgrouper assessment for the continental U.S. population. This project would not have been possible without ongoing collaboration with researchers from Florida State University, Everglades National Park, and the recreational fishing and SCUBA diving communities.

Eddie sat down on the deck and braced his foot against the rail, I figured we were into a big one. When his hat fell off, and he started to make grunting sounds, I was sure of it.

Eddie looked up at me with a twisted smile and was just hanging onto the rod for dear life. Something was living in this wreck 10 miles off southwest Florida, and whatever it was had already beaten us up several times.

But on this day we were maxed out on gear big enough to crank one of these monsters up ... if only Capt. This started out innocently enough a few weeks earlier when a couple of fishing buddies and I dropped a live pinkish on 30# mono down on a wreck 50 feet deep looking for a grouper dinner.

Something big grabbed it, screamed out about 40 feet of drag, got into the wreck and cut the line on something sharp. Something wolfed down the pinkish and took line like the rod was tied to a dragster.

It had to be a big grouper, a shark, a giant ray, or maybe a huge barracuda. The rod bent over 180 degrees, the back of the boat went down 6 inches, and the 150# braid snapped like a rifle shot.

I asked the guys in the local bait shops if they knew any captains up for the task of fishing for seemingly unwatchable monsters. The Goliath, once called the Jewish, is the biggest member of the grouper family.

Goliath's can live 50 years and grow to behemoth size. The winds of spring kept us inshore for a couple of weeks, so we enjoyed the opportunity to fish the bridges for pompano and sea trout.

It finally took a rig spooled with 150# braid, a 500# mono top shot, and huge #16 circle hook under 2 ounces of lead to bring a Goliath to the surface. Eddie's wreck, and he pulled a big Spanish mackerel out of his cooler, the one bait he said Goliath can 't refuse.

It was a short, furious, and profane battle, a hard fought back-and-forth fish fight, exciting to watch with an uncertain end. Eddie prevailed, and suddenly a giant brown fish appeared on the surface and lay at the side of the boat as exhausted as Capt.

On the next calm day I returned to my wreck lying now in water so clear you could see its dark silhouette on the white sand bottom 50 feet below. I went over the side to find an old shrimper torn apart by hurricanes and fishermen's anchors, its wheelhouse barely recognizable.

And then they appeared, slowly emerging from the shadows of broken masts and rigging. A fearless giant Goliath carries the remnants of three different rigs ripped from fishermen.

Three fishing rigs hung from his mouth, one still with its sinker, medals of recent battles won, and then I recognized one of my rigs, the 150# braid to a black swivel to 200# mono, hanging out of the left side of his mouth. There was the proof: These were the bad boys that had beat us up, and a few other fishermen, too, by the looks of it.

I returned to the surface knowing those hooks will soon rust and the line will fall away, and these Goliath's will own this wreck for many years to come. Goliathgroupercan be found across the Caribbean from Central America, around the Gulf, and up the Atlantic to the Carolina's, but they are most plentiful in Florida.
