Blacktip Island Scientists Plan Cowboy-Style Grouper Roundup

A group of Blacktip Island marine scientists Thursday announced they will stage a Wild West-themed Nassau grouper roundup next week so they can implant location transponders in as many of the fish as possible to track their movements and behaviors.

“We’ve been randomly tagging Nassaus for years, but it doesn’t give us an accurate picture of their habits,” Tiperon University-Blacktip marine science professor Goby Graysby said. “Rather than continuing all higgledy-piggledy, our plan is to round up every grouper on the island in one big pen so we can stick ‘em all.

“It’s a big project, and we’ll need every volunteer diver we can get,” Graysby said. “To encourage participation, we decided to model it after an Old West cattle drive. Without the horses and lassos, of course. But we will have divers, some on underwater scooters, herding the groupers into a big net enclosure just out from the public pier. Then we can tag them all at one time.”

Organizers expect the roundup to be a multi-day affair.

“Blacktip’s a small enough island, it’s likely we can get almost all the Nassaus,” Ginger Bass said. “Thing is, it’s also big enough it’ll likely take us several days to get all the fish corraled and tagged. Weeks, even, depending on the number of herders we get.

“We’ll have our aqua-buckaroos working ‘round the clock, and sleeping on boats,” Bass said. “There’ll be a chuckwagon-style pontoon boat bringing meals to herders so they don’t waste time going home and cooking dinner. If this works out like we think it will, this could be the new standard for fish tagging worldwide.”

Island environmentalists, however, opposed the plan.

“Why do they need every Nassau to have a transponder?” ecologist Harry Pickett said. “They can’t study the grouper without terrorizing them? In a marine park. And what about the other reef creatures they’ll traumatize? And the coral they’ll damage?

“This central net-corral they’ve installed is anchored in living reef and will cause irreparable damage,” Pickett said. “And once they release the grouper, what guarantee is there the fish will go back to the section of reef they came from? They might just stay there, and there’d be no groupers anywhere else on the island.”

Organizers remained optimistic.

“We’ll have contests as we go along, to keep volunteer fis-pokes engaged,” Graysby said. “We’ll have time trials, where individual divers compete to see who can round up and tag a grouper the fastest. Like an underwater rodeo. This could become the Tiperons’ national sport. Maybe even get in the Olympics when we host them.

“We also encourage all participants to dress in Western-themed scuba gear,” Graysby said. “We’ve seen some nice neoprene cowboy hats and vests already. And rumor has it several folks’ll be turning up in leather chaps.”

Participants will receive free meals during the roundup, and ‘Grouper Wrangler’ t-shirts afterwards.

Blacktip Island Divemaster Trains Grouper To Do Math

A Blacktip Island divemaster has taught a Nassau grouper to do basic arithmetic to entertain dive guests, the Caribbean island’s Eagle Ray Cove resort announced Wednesday.

“Gage Hoase’d been messing with that grouper at Hammerhead Reef for ages. Bernie, the one who likes to be petted,” Eagle Ray Divers operations manager Ger Latner said. “We had no idea what Gage was up to until he had the fish add and subtract for guests during a dive.

“Nassaus are smart, on the fish scale, but this blew us away,” Latner said. “Divers can ask Bernie math questions, and the damn fish’ll answer back. Correctly. Our boats are packed, and we’re diving Hammerhead two, three times a day.”

Hoase said Bernie’s skill came about by chance.

“He’s a friendly fish, always interested in what I was doing,” he said. “One day I was counting divers on my fingers and I noticed him bobbing his head in time with my counting.

“I held up four fingers on each hand and he nodded eight times,” Hoase said. “From there it was a natural jump to writing math problems for him on an underwater slate.”

Dive guests raved about their encounters.

“I asked Bernie what seven plus nine was and that little dickens answered right!” said Eagle Ray Cove guest Kenny Bloate. “He bobs his head for single digits and shakes it side-to-side for larger numbers: one shake and six nods equaled 16! They charge extra for the dive, but it’s worth it.”

Other divers were skeptical at first.

“I thought it was BS, then I put Bernie through his paces,” Juanita Cerf said. “I even gave him a problem with a negative number as the answer and he turned 180 degrees and counted it right out.”

The island’s scientific community remains dubious.

“We dived Hammerhead Reef without any Eagle Ray Dive staff present and found the fish to be curious, but otherwise untalented,” Tiperon University-Blacktip marine biology chair Goby Graysby said. “Our working hypothesis is Mr. Hoase is signaling to the fish.

“That’s not to say Gage’s work isn’t impressive,” Graysby added. “To train a grouper to respond to signals is unusual. But the fish can’t perform arithmetic.”

Hoase rebuffed Graysby’s claim.

“It’s a game for Bernie. If he doesn’t like you, he won’t play,” Hoase said. “And fish learning is more common that you think. A woman on Barbados taught a parrotfish to tell time. And a humphead wrasse in Palau can spell. In Latin and Cryrillic scripts. It’s working on kanji characters, too, but so far is only up to emojis.

“The next step for Bernie is quadratic equations,” Hoase said. “He understands them, but we haven’t worked out a system for him to communicate anything like ‘x=y+2’. It’ll probably involve barrel sponges.”
