Warsaw Grouper Turns Out to Be A Goliath, Angler In Big Trouble
An Alabama man faces a single misdemeanor charge after test results show the
enormous grouper he and his fishing party landed off St. George Island was not a
Warsaw grouper but a protected goliath grouper.Florida Fish and Wildlife
Conservation Commission (FWC) Investigator Eric Johnston said boat owner and
operator Billy Daniels, Moody, Ala., has agreed to the terms of a "deferred
prosecution agreement" with the state attorney's office in Apalachicola, which
stipulates he pay a $150 fine and contribute $150 to Florida's Wildlife Alert
Reward Program. The agreement spells out the misdemeanor charge will be
dismissed after 90 days, assuming Daniels is not charged with other fish or
wildlife law violations in Florida.Daniels, DOB 05/24/58, his son, Shawn of
Stanley, Kan., and two fishing buddies from Kansas, caught the gargantuan
grouper they believed was a legal Warsaw grouper June 25, while fishing 15 miles
southeast of St. George Island in 80 feet of water. Shawn Daniels actually
caught the fish, which measured 82 inches long and 66 inches in girth and was
estimated to weigh approximately 446 pounds.They brought the grouper back to Bay
City Lodge in Apalachicola, posed for photos and dressed the fish on the dock.
After the photos and stories ran in numerous newspapers and showed up on Web
sites and blogs, the calls started coming in to the FWC from those who thought
the fish was a goliath grouper.Johnston said Daniels turned over a sample of
meat for DNA testing. He said Daniels has been nothing but cooperative during
this period.Daniels was cited rather than his son, who caught the fish, because
as captain he is responsible for the fish being landed, Johnston said.Goliath
grouper numbers dropped precipitously in the 1970s and 1980s because of
overfishing. The species has been protected in Florida waters since
1990.Experienced offshore anglers say Warsaw grouper are usually found in
300-400 feet of water. Goliath grouper are typically found in more shallow
coastal waters.

If it takes a DNA test to ID the species of fish, how can you blame the fishermen?
