"The laws governing the labeling of seafood in the marketplace are unfortunately not strong enough," she said. "And there have been many investigations when people have gone to the supermarket, done genetic testing, and found that it wasn't the species they wanted."
But shouldn't a fish filled with contamination get sick or die? Shouldn't it be sore-covered and tumor-ridden, obviously inedible? Sometimes they are. But sometimes, as in the case of a species of killifish found in New Bedford harbor, fish just shrug off the contaminants.
National Geographic Big Things Come from Small Beginnings: The Mystery of the Sick Sea Lions National Geographic On a cold, foggy morning along the Malibu coast, a small brown lump emerges from the sea and waddles ashore.
“These sea lions might be our sentinel that tells us something else is going on that’s going to be affecting other fish, that’s going to be affecting sharks, that could have much broader concerns throughout the ocean.”–Sarah Wilkins of National Marine Fisheries Service, in an interview with NPR
If we can understand the factors that have created this immediate issue, we may be able to better manage ocean resources in the future. However, this crisis begs the bigger philosophical question of whether or not a wild ecosystem is something that can be, or should be, “managed” by humans.
Do we really need to be fishing out hundreds of thousands of metric tons of wild menhaden from the Chesapeake Bay, krill from the Antarctic, and sardines and squid from the California Pacific just to get Omega 3’s or feed pigs? As a lynchpin for the whole ecosystem, these fish have much more value left alive in the ocean than they do dead as fertilizer on a corn crop.
Most of these wild-caught forage fish, ironically, end up feeding farmed fish–and starving their wild counterparts! (It takes 7 pounds of sardines to grow one pound of pen-raised tuna.) Climate change has made it even more difficult to predict when and where these fish will be. Without that consistency, it’s virtually impossible to “manage” an ever-changing ocean ecosystem.
As we 'now' know Plastic has a longer half-life than most natural floating marine substrates, and a hydrophobic surface that promotes microbial colonization and biofilm formation, differing from autochthonous substrates in the upper layers of the ocean.
On the Trais: Tidepooling Juneau Empire (subscription) There were at least five kinds of sea cucumbers, a big purple one, medium orange ones, small white ones, smaller translucent ones, and thousands of the very small black 'tar spot' cucumbers.

Always return your finds carefully from whence they came, or just view is better.
Re link;; When the tide goes out, it’s time for a natural history treasure hunt. This year, both May and June brought really low tides (more than minus-four feet) at more or less reasonable hours of the day. Of course, we had to go looking for weird and wonderful creatures that might be visible. We went to two likely spots, one in May and the other in June. At one of them, we were supervised closely by a pair of watchful black oystercatchers.
Once a lush and healthy estuary, the Indian River Lagoon is now an enigmatic death trap. Running along 40 percent of Florida’s Atlantic coast, the lagoon’s brackish waters harbor a mysterious killer that has claimed the lives of hundreds of victims.
Young fish leap in the wake of a warden's patrol boat as it motors through waters off Jamaica's southwest coast that are a brilliant palette of blues.
Marian Locksley's insight:
After rampant destruction of local fish habitats over decades, marine life is gradually rebounding in Bluefields Bay now that every minnow and mullet, each sea urchin and snapper is protected from spear guns and nets.
This 6½-mile (10-kilometer) long stretch of water, patrolled daily by a small team of wardens and marine police, is one of a growing number of no-fishing zones in the Caribbean, where most coastal reefs have been severely damaged by overfishing, pollution, and more recently global warming.
"If we want to protect our future, setting up more places like this is a no-brainer. If we keep destroying areas with thousands of baby and juvenile fish, where will the big fish come from tomorrow?" said Wolde Kristos, chairman of the Bluefields Bay Fishermen's Friendly Society that lobbied Jamaica's government to create the reserve, the biggest and most robustly enforced of the island's 14 fish sanctuaries.
Across the Caribbean, governments and fishing communities are beginning to use such "no-take" zones to help rebuild severely depleted fish stocks and make coastal ecosystems more resilient to a warming planet and acidifying oceans.

The Guardian reports 10th July 2013:”Krill is the backbone of the food web in the Antarctic and is the key food for penguins, seals, fish and whales… [and] between a third and a quarter of carbon dioxide that comes from burning fossil fuels is absorbed by the oceans.
“A new study, carried out by scientists at the Australian Government’s Australian Antarctic Division (AAD), has found that once levels of dissolved carbon dioxide in the ocean reach about 1250 microatmopsheres, the numbers of krill eggs successfully hatching starts to decline dramatically. Some of the areas for krill already reach 550 microatmospheres.
“AAD marine biologist Rob King, one of the co-authors of the study said: ‘If you want to minimise the chances of major ecosystem disruption then this study shows that emissions would need to be moderated from the current trajectory. Antarctica is an unusual ecosystem because this species – the krill – is responsible for passing on so much primary production to higher predators, including fish, whales, seals and penguins.’
KVAL Scientists study massive krill die-off on coast KVAL Millions of krill, a tiny shrimp-like animal that is a cornerstone of the ocean food web, have been washing up on beaches in Southern Oregon and Northern California the past few weeks and...
The cute and comical seabirds called puffins have returned to several Maine islands and are finding plenty of food for their young chicks unlike last summer when many starved.
Marian Locksley's insight:
But researchers remain concerned.
Occupancy of puffin burrows on Matinicus Rock and at Seal Island, the two largest U.S. puffin colonies, are down by at least a third this season, Kress said. That likely means many birds died over the winter and others were too weak to produce offspring this season, he said.
Overfishing has reduced competition for food, allowing jellyfish whose stings can cause pain and nausea, to thrive (OK you practice #Mediterranean #overfishing @SeaShepherd you get a lot of #jellyfish #climatechange simple fact
Marian Locksley's insight:
The problem is further compounded by jellyfish feeding on the larvae of fish species. Scientists believe that human interventions that change the shape of the coastline and affect currents could also provide ideal breeding zones that encourage blooms.
Likewise, the NAVFORSOL will henceforth take this kind of activity as priority projects together with maritime security and law enforcement to continuously guard our seas and environment from exploitation”.
Minneapolis Star Tribune Pollution concerns abound in frac sand waste streams Minneapolis Star Tribune Rich Budinger, president of the Wisconsin Industrial Sand Association, an industry trade group, said sediment pollution is indeed a threat to...
Marian Locksley's insight:
with runoff and waste piles, state officials and some frac-sand companies are wary about the widespread use of a chemical called polyacrylamide to clarify sand-processing water. Polyacrylamide contains residual amounts of acrylamide, a neurotoxin linked to cancer and infertility.
So far, no one has detected acrylamide in aquifers or soil around industrial sand mining sites, and in Wisconsin’s Chippewa County, a rare acrylamide monitoring program in an area with lots of frac-sand activity has not sounded any warnings.
But small amounts of acrylamide have been shown to accumulate in mining waste water, and the chemical is widely considered to be present in stockpiles of discarded fines.
Mining reclamation plans call for those heaps to be buried back in the ground in unprecedented volumes — some of it at mines where digging goes well below the water table.
Tiller operates a frac-sand mine near Grantsburg, Wis., and still is resolving a spill of dirty water that reached the St. Croix River last year. The U.S. Army Corps of Engineers treated it as a violation of the federal Clean Water Act and the Wisconsin Department of Justice is considering possible sanctions.
