LARFF gets a fair number of fish and beauty shots coming across the electronic transom, but this one definitely takes the cake. Know what it is?
What’s a pacu?
As the fly fisher who hooked it said via email, “I caught that exotic fish and posted it on my Facebook, and a lot of friends told me it was a pacu, not native to here, and it matched photos from the Internet.”
James Czasonis went on to write that it looked like a big pirahna, but the teeth were more flat. Although the teeth aren’t visible in these shots, the host of “River Monsters,” Jeremy Wade, explains here that the flat teeth are used for crushing seeds, unlike a pirahna’s that are sharper and used for tearing apart flesh. Both are native to the Amazon River in South America.
Pacus have been found in Papua New Guinea, and much closer to home in Michigan, Illinois, Ohio, and now in Los Angeles.
How’d that happen?
Apparently, some unaware aquarium owners believe these fish will only grow “so big” because of the glass confines of their watery cages. But, that logic turns out to be a myth and when the pacu overstays its welcome, it gets dumped into local waterways.
And, yes, it is illegal to dump nonnative exotic fish.
Authorities in Ohio aren’t overly concerned about a pacu takeover because the fish dies out once the weather gets cold.
As for the potential threat here in warmer climes, Czasonis said this was the only one he’d seen or caught, and “I still didn’t want to hold it up and let it back into the river.”
See you on the river, Jim Burns
