First Invasive Lionfish Found in Brazilian Waters

Thats right folks the infamous Caribbean species has made its way all the down the coast to Brazilian waters. A single lionfish was speared off the coast and a team of researchers including scientists from the California Academy of Sciences confirmed species analysis through DNA testing. A massive focus has been placed on the finding while scientists urge for a swift intervention plan: “For the past 20 years, invasive lionfishes have been restricted to the Caribbean,” says Luiz Rocha, PhD, Academy curator of ichthyology.fig1 “This new record shows us that lionfishes are capable of reaching far into other areas of the Atlantic, and other countries should be on guard, preparing for them to arrive.” The effort to stem invasion includes minds from all over the globe because the species (Pterois volitans) is particularly aggressive and can consume just about any an reef fish that will fit into its mouth. Rocha adds: “Brazilian fishes are being hit from all sides,” says Rocha. “Overfishing and habitat degradation are pervasive, and not even the most basic fisheries data are being collected. The best—and easiest—way to control an invasion is by trying to slow it down at the start.” Read more here.… More:

UPDATE! Our Lionfish Odd Couple Now Has Footage!


As you recall I previously posted about the strange relationship between Jim Gryczanowski’s Pterois volitan and his Blue Stripe Amphiprion clarkii. Well today I have an exciting update for you with this fantastic video of the adorable duo! Jim reports this behavior has been ongoing for a few weeks now, and while the couple seem comfortable with their living situation, the Clown is reportedly a bit stingy, and has yet to share his food with Mr. Lion. Let’s hope she realizes quickly that you must feed your man if you’d like to stick around. I know for sure Jared would eat me if I didn’t cook a decent meal every once in a while.More:

“Shocking” Not So Shocking Findings About The Lion

“National Public Radio recently published the following article to their website, about a young scientist’s experiment exposing lionfish to decreasing levels of salinity:

Sixth Grader’s Science Fair Finding Shocks Ecologists

Shocked! Just shocked!

Meanwhile, aquarium fish keepers have known about this for decades. It’s called hypo-salinity, and it’s an important part of the quarantine procedure. Fish can survive at low salinity; invertebrates cannot. Putting marine fish in low salinity rids them of … More:

Florida to Ban All Pterois Lionfish Imports Beginning August 1st

We keep harping on the lionfish invasion of the Caribbean Sea, Atlantic Ocean, and pretty much all waters surrounding Florida because it is a serious, ongoing issue with seemingly no end in sight. Despite the best efforts of scientists to understand the issue, legislators to fix the problem, and recreational fishermen to eradicate the invaders, the problem persists to the point where different and often drastic measures have to be given a good look. The latest attempt to help tackle the invasion is the straight up ban on the import of all lionfish from the Pterois genus into Florida. But is it the right move? As spelled out in one of Ret Talbot’s latest contributions to the Reef2Rainforest blog, Florida Fish and Wildlife Commissioners unanimously approved the prohibition of the “importation of live lionfish from the genus Pterois“, approved divers to use rebreather equipment to harvest lionfish, and will allow the Executive Director to issue permits to spearfisherman to remove lionfish and other non-native species from areas where the activity was previously prohibited. Ret goes on to point out that lionfish from the genus Dendrochirus are not considered in this ban despite there being significant genetic similarities between them and members of the Pterois genus. This new set of rules goes into effect on August 1st, and as usual, there are good arguments from both sides of the aisle. One of the key incentives intended by this ban is that marine aquarium importers who still rely on lionfish as part of their product offering will start collecting fish out of Florida waters to fill their demand. This approach, coupled with aggressive erradication efforts from other industries, is hoped to be able to keep the lionfish under better control, though nobody knows what real impact will be had.

Lionfish Eye Photo, Invasive Creatures, Deadly Fish

Hi all, I have a lionfish eyeball for you all today mainly because I don’t have anything else to send! How is this possible you ask when I am always in the water with a camera?? Well, most days I’m just shooting the submersible with it’s passengers and lately at night only blue-light photos so I really don’t have anything new at the moment. We did do a deep-water fish collecting dive yesterday so I may have some new rare aquarium fish pictures for you soon but they are still out on the reef and take a week to decompress and acclimate to the warmer temps. I took this lionfish eye photo the other night while out searching for small corals that we had previously shot with blue-light
