We Know Very Little About the Ocean. NASA Earth Explorer and scientist Gene Feldman has studied the ocean for 25 years, he says that “even with all the technology that we have today — satellites, buoys, underwater vehicles and ship tracks — we have better maps of the surface of Mars and the moon than we do the bottom of the ocean. We know very, very little about most of the ocean. This is especially true for the middle and deeper parts far away from the coasts. ”

Optimum Fisheries Could Yield $138 Million More. A new study by the Pew Charitable Trusts indicates the Southeast U.S. suffers $138 million in economic output annually because some fish populations are not managed at optimum levels.
Jellylfish Blooms Could be Caused by Human Structures. A study from the University of Western Australia concludes that jellyfish blooms could be caused by human structures such as harbors and tourist facilities that are perfect sanctuaries for jellyfish polyps. Most theories used to explain the blooms cite lack of predators or competitors to jellyfish at their more mature swimming stage.
New Camera to Help Protect Scallop Fisheries. A new stainless steel instrument housing a camera is being used on the East Coast of the U.S.to take millions of pictures of ocean floor where scallops are found. The idea is to better understand and protect the half-billion dollar Atlantic scallop catch.

Sustainable Fisheries Address in SeaWeb Marine Science Review. The most recent SeaWeb Marine Science Review is a special issue focused on trends in seafood sustainability. Two key articles stand out. The first, published in Fisheries Research, estimates that “the intensification of global fishing effort and the ensuing depletion of marine fish stocks causes economic losses of 50 billion US dollars annually.” The article points out that “data deficiencies current ly hamper analysis of global fishing effort.” The second paper, published in Conservation Biology, points out that perceptions on the status of globally fisheries might partly stem from how data on trends in catches over time have been used. The authors say that on the basis of trends “it has been suggested that about 70% of all stocks are over-exploited due to unsustainable harvesting and 30% of all stocks have collapsed to <10% of unfished levels. The new study concludes that conclude that “at present 28–33% of all stocks are over-exploited and 7 – 13% of all stocks are collapsed.” This new assessment also suggests that the proportion of fished stocks that are over-exploited or collapsed has been fairly stable in recent years.
Study Suggests Dolphins Increase Reproduction After Hurricanes. A recent article in a Scientific American blog suggests that the noticeable increase in dolphin calves following Hurricane Katrina off Mississippi was due at least in part to the reduction of fishing effort and commensurate increase in Gulf of Mexico fish populations. Fishing effort was reduced in the Gulf following Katrina due to damage to fishing vessels. The blog says that “according to one estimate, 87% of commercial fishing vessels were damaged or destroyed, which meant a decrease in the amount of seafood brought into shore by nearly fifteen percent, in 2005 and 2006, compared with 2004. There were also forty to fifty percent fewer commercial and recreational fishing licenses granted by the state of Mississippi in 2005 and 2006.”
