Paleontologists have discovered a 380 million year old fish fossil that had abs. Previously, researchers though abdominal muscles existed only in land mammals. It was a surprise to find them in fish because their main method of propulsion is by ‘flapping’ their tails left and right, meaning that the muscles are found on either side of the body. Now the question is if these fish abs had the same function as abs in land mammals.
The International Pole and line Foundation is praising the Indonesian fishing industry’s efforts in line-caught tuna. Indonesia is the world’s largest tuna fishing nation and while pole and line fishing is a common practice, the fishing industry currently doesn’t distinguish between pole/line and purse seine tuna. In terms of sustainability, their move to increase the market for pole and line and hand line caught tuna is a big step in the right direction.
Next month, the New Zealand government plans to announce a long-awaited threat management plan for the critically endangered Maui’s dolphin, but some worry it won’t be enough. There are currently only 55 Maui’s dolphins over one year in age and the biggest threats to their survival as a species are gill netting and trawling. Research shows that more than 80 percent of the dolphins’ habitat is exposed to those kinds of fishing methods. If nothing is done, experts believe the dolphin will disappear by 2030.
