In an earlier post I wrote about how divers kill and catch the non-native lionfish that are causing so much trouble in the waters around the Gulf of Mexico, Florida and the Caribbean. The methodology is simple, kill them as humanely as you can, take care with the spines, but then what…?… More:
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. “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:
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:
“National Public Radio recently published the following article to their website, about a young scientist’s experiment exposing lionfish to decreasing levels of salinity:
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:
