Getting serious about overfishing

The Economist – Even the names at Sutton Harbour give it away. While the pleasure boats, including Windfall and Felicity, gleam in the sunshine, the light warms rust on the decks of craft such as Pisces. The fishing industry is struggling to stay afloat in Plymouth, a port in Devon. Locals grumble about regulation, fuel costs and the dearth of crew. Revenues are stagnant and the facilities Read More…

Modeling invasive activity: Zebra mussels’ infiltration of North…

Phys Org – The invasion of nonnative species has widespread and detrimental effects on both local and global ecosystems. These intruders often spread and multiply prolifically, overtake and displace native species, alter the intended interactions between flora and fauna, and damage the environment and economy. A particularly pesky invader is the zebra mussel (Dreissena polymorpha). Given its Read More…

New information on how long some rockfish live and how often they…

NOAA News – Some things just get better with age. Like rockfish mothers. A rockfish might not start spawning until she is 25 years old. As she gets older she produces more, and more robust, young. She continues to produce them over many years, into advanced age – which for some rockfish means 100 or 200 years. That is the sluggish end of the spectrum, but rockfish in general are Read More…

Grunion Fish-tival: San Pedro Party

NBC Los Angeles – Every party ever thrown has likely reflected a specific theme, or honoree, or time of day in terms of the activities, how the guests dress, and the other touches that make up the anatomy of a bash. With that in mind, if a grunion were to host an evening soiree, what would go into the affair? Lots of salt water? And sand? Would the moon need to be at a certain phase, and Read More…

Scientists say the pace of sea level rise has nearly tripled since…

Washington Post – A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway. “We have a much stronger acceleration in sea level rise than formerly thought,” Read More…

Rising Sea Level Will Double The Frequency Of The Coastal Flooding By…

Science Times – Researchers recently tracked the rising sea level due to the global warming. They observed that it can enhance and double the chances of frequent coastal flooding by 2050. According to this research study, the tropical regions will be the worst affected areas on earth by the coastal flooding. The increment of the ocean watermark by 10-to-20 centimeter globally would double Read More…

Gulf of Maine will become too warm for many key fish, report says

Portland Press Herald – A new study by federal fisheries scientists predicts the warming of the Gulf of Maine will cause a dramatic contraction of suitably cool habitat for a range of key commercial fish species there. On the other hand, lobsters are more likely to find hospitable areas. The study by seven scientists at the National Oceanic and Atmospheric Administration’s Northeast Read More…

Climate change refuge for corals discovered (and how we can protect…

Phys Org – WCS scientists have discovered a refuge for corals where the environment protects otherwise sensitive species to the increasing severity of climate change. The bad news is that the reefs are showing signs of being overfished and weak compliance with local fisheries laws needs to be reversed to maintain the fish that help to keep reefs healthy. The scientists describe their Read More…

225,000 Chinook salmon will be released to feed endangered orcas

Sooke News Mirror – By the end of May, the first batch of around 225,000 young chinook salmon will be released into the ocean to help feed B.C.’s endangered orcas. The program, the first of its kind locally, involves catching wild fish and facilitating their reproduction in a hatchery – and now the salmon are set to be released from a uniquely-designed pen off the docks of the Sooke Read More…

Marine Species Distribution Shifts Will Continue Under Ocean Warming

NOAA News – Scientists using a high-resolution global climate model and historical observations of species distributions on the Northeast U.S. Shelf have found that commercially important species will continue to shift their distribution as ocean waters warm two to three times faster than the global average through the end of this century. Projected increases in surface to bottom waters of Read More…
