11. Aquaculture creates jobs. These jobs pay well and extend throughout the year; well beyond the brief tourist season.
22. Shellfish aquaculture improves water quality as the oysters, clams and mussels all feed by filtering the water. They make it clearer so that other important plant life such as eel grass can thrive. They remove harmful nitrogen that contributes to algae blooms and red tides.
33. Aquaculture draws eco-tourists. Touring an oyster farm is a great way for parents to get their families outside and learn about the coastal environment.
44. Aquaculture improves the fishing as many other creatures will move in among the structure and shelter provided by the shellfish. These smaller creatures support the food chain that draws in the larger sport fish that fishermen love to catch.
55. Aquaculture makes your shoreline safer. The key to a successful park is having people there to provide a sense of security. It is the same for coastal estuaries with the addition that having an oyster farmer with a boat can actually save lives.
66. Aquaculture teaches youngsters about the meaning of work. Working around the tides, oyster farmers are out at many different hours; frequently enduring cold and inclement weather. What better way for a young person to vicariously realize that earning a dollar can be a demanding task.
77. People who raise shellfish are great advocates for the environment. If the water quality drops, their business can be damaged or permanently shut down. So they care… A lot.
88. It puts your town on the map. Duxbury, Wellfleet, Milford, Connecticut and Damariscotta, Maine are well-known in the food world because of their oysters.
99. Local aquaculture creates an opportunity to purchase delicious fresh seafood wholesale at the source. This locavore resource in turn can foster a restaurant hub.
110. It gives your town a centerpiece to organize a fun festival that brings your town together and boosts the local economy.

Posted By: Matthew McGrath January 14, 2016KEYPORT — Oysters, which play a critical role in estuary ecosystems, may soon return to Raritan Bay in small numbers as part of research and restoration projects.
State lawmakers approved a bill earlier this week that would allow artificial oyster reefs to be constructed in waters now closed to shellfish harvests provided they are invisible to the public and cannot be easily accessed.
The state Department of Environmental Protection would have one year to make new rules for the building of those reefs provided Gov. Christie signs the bill.
The bill’s approval was a victory for the NY/NJ Baykeeper, which has its headquarters on West Front Street. It has long lobbied Trenton lawmakers and officials to allow artificial reefs to be built in Raritan Bay and other waters in the New York-New Jersey estuary.
Baykeeper’s statement: click here.In 1999, the Baykeeper staff installed artificial reefs in cages in Keyport Harbor and the Navesink River near Red Bank. In 2010, the state Department of Environmental Protection ordered the reefs destroyed.
Oystering was once one of Keyport’s primary industries. Oyster harvesting even pre-dated the founding of the town and was one of the primary activities of the Kearny Family’s Key Grove Plantation on which the town was later built.
Over-harvesting, pollution, disease and silt all contributed to the demise of the oyster industry.
In recent years, New Jersey’s oyster harvests have been on the rebound. The open waters in the Delaware Bay still provide some natural harvests, but a niche industry of oyster farmers has grown up on the South Jersey shorelines.
State officials insisted that poachers could harvest the Baykeeper’s oysters and sell them to a restaurant unless the reefs were patrolled around the clock. That, in turn, would have made people sick and could have potentially destroyed the state’s growing shellfish industry.
Officials at the Baykeeper offered to assist the DEP with coastal patrols, but that offer was declined and a half a million oysters had to be ripped from the bay and the river to be tossed in the trash.
Baykeeper staff continue to insist that the order was misguided. The oysters were placed in cages and the individual oysters were too small to eat, said Sandra Meola, the Baykeeper spokeswoman.More so, they Baykeeper staff have argued the logic of excluding shellfish restoration projects from closed waters is a mistake.
Oysters feed by filtering out nutrients suspended in the water. That same process can remove pollution from the water. A single oyster can filter about 50 gallons of water each day.
New reefs were built by Baykeeper staff within the jurisdiction of Naval Weapons Station Earle because of the round the clock protection the Navy would provide for their waters.
Meola said that initial results from that small reef were positive. Water quality improved and species of fish were being recruited to the reef, but she did not release hard data because a complete analysis hasn’t been made.
The Baykeeper is not the only organization to build artifical reefs. The Barnegay Bay Partnership and the Littoral Society each have shellfish restoration projects in Barnegat Bay, which was also a center for the state’s historical shellfish industry.
Gef Flimin, a Rutgers University research extension agent working with Barnegat Bay Partnership, said he also did not have data to release. State studies show that water quality in the bay has improved and that the numbers of shellfish have increased, he said. Flimin said he wouldn’t presume that the work of restoring shellfish in Barnegat Bay was the sole cause of improving environmental conditions there.
The Baykeeper staff is looking forward to working with DEP officials to craft the rules for research reefs if Christie signs the bill, Meola said.

Both are calium carbonate, but one is hard, the other is soft. Why?
How seashells get their strength
Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearlsJanuary 08, 2016
RICHLAND, Wash. – Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A study today in Nature Communications reveals how soft clumps get into crystals and endow them with remarkable strength.
The results show that such clumps become incorporated via chemical interactions with atoms in the crystals, an unexpected mechanism based on previous understanding. By providing insight into the formation of natural minerals that are a composite of both soft and hard components, the work will help scientists develop new materials for a sustainable energy future, based on this principle.
"This work helps us to sort out how rather weak crystals can form composite materials with remarkable mechanical properties," said materials scientist Jim De Yoreo of the Department of Energy's Pacific Northwest National Laboratory. "It also provides us with ideas for trapping carbon dioxide in useful materials to deal with the excess greenhouse gases we're putting in the atmosphere, or for incorporating light-responsive nanoparticles into highly ordered crystalline matrices for solar energy applications."
