![]() ![]() According to National Geographic, some ocean fisherman squirt sodium cyanide on the coral reef to stun the fish and make them easier to scoop up. And, the horrific way many of these ocean animals are being harvested should make you think twice about scooping up a Nemo or Dory at your local pet store. No matter how cute Dory is and how much you love her, she will never make a good pet for some pretty serious reasons.Īccording to National Geographic, "A full 98 percent" of saltwater fish must be captured in the wild because they can't yet be bred in captivity. The site interviewed University of Queensland school of biological sciences PhD candidate Carmen da Silva who also said, "There's nothing wrong with owning a marine fish in an aquarium but I think a lot of people didn't realize 90 percent of clown fish sold are taken from the wild." So, with that in mind, it's time for another lesson pegged to Finding Dory: Don't buy a blue tang fish. Despite the fact that it very clearly illustrated that fish don't want to live in tanks and don't like being stolen from the ocean, " Clown fish sales skyrocketed," after the movie's release, according to The Huffington Post Australia. Leaders tend to be females."Ĭoncern for fish welfare is on the increase.Back in 2003, when Finding Nemo came out, thousands of people completely missed the memo on what the message of the film was. Scientists suggest that the route is culturally transmitted and followers even simulate the idiosyncratic body postures of the leaders, which is the best suggestion of imitation in fishes to date. So clearly there is some redundancy in their navigational system and it has been suggested that they store the layout of their routes as a cognitive map. When researchers moved landmarks in their environment slightly, the fish tended to detour towards them, but if they were moved by more than 6m, the fish ignored them. "These fish undergo daily migrations from resting to feeding locations as well as annual spawning migrations. Brown surgeon fish have been studied in the Red Sea with respect to their spatial learning abilities and experiments show that they pay a lot of attention to landmarks as they are navigating around the reef. "For example, the family to which they belong (surgeon fishes) have larger than average relative brain size which is a common trait with fish associated with complex environments, and coral reefs in particular. This piece written last month by Emily Sohn for Hakai Magazine explains the push to breed captive blue tangs so that, at the very least, these fish won't be harvested in large numbers from the wild. That "under threat" sentence, together with the important ecological role for this fish in coral reef protection, caught my attention: It's exactly why scientists are so worried right now. They graze algae on coral reefs, which is a very important job because it prevents the corals from being over-grown." They have a huge distribution (Indo-Pacific) but are under threat from illegal collection. They have very sharp spines on either side of their tail which erect when frightened. "We know that their skin reflects light at 490nm (deep blue) and they tend to get lighter at night (this is under hormone control). ![]() But that is true for the vast majority of the 32+ thousand species of fish out there. ![]() "You'll be shocked to discover that we actually know very little about cognition in blue tangs. Now, with two weeks to go until the very-hyped opening of Finding Dory - the Disney/Pixar sequel to Nemo - concern mounts for what may happen with the Pacific blue tang. Some children, seeking to give their new pets freedom through the same route used by Nemo in the film, flushed their fish down the toilet. It happened with Finding Nemo, when children clamored for clownfish. It happened in the wake of Beverly Hills Chihuahua - and the tiny dogs paid the price when they were abandoned at high rates. It happened when the Teenage Mutant Ninja Turtles movies came out at one point, 90 percent of purchased turtles were estimated to have died in the United States alone. Before long, the cute new member of the family becomes too much trouble, or isn't cared for properly the animal dies, is abandoned, or is surrendered to overwhelmed rescue groups. Then they rush out to buy one of the very same type of animal, to keep as a pet. Families go to see movies that feature fun, friendly animals on the big screen. ![]()
