Mystic — U.S. Sen. Richard Blumenthal, D-Conn., came to Mystic Aquarium on Tuesday to announce that $1.76 million in federal funding has been approved for projects designed to help improve the health of Long Island Sound.

This includes $44,000 to help the aquarium expand its education efforts about the importance of keeping plastics and other debris out of the water. That debris sometimes is ingested by fish and marine mammals, injuring or killing them. Some are brought to the aquarium to receive care.

Blumenthal, who credited the state’s entire legislative delegation with securing the funding from the Environmental Protection Agency’s Long Island Sound Futures Fund, said the money will be shared among a large group of organizations and municipalities involved in 20 separate projects. Each group has matched the amount of the grants resulting in $3.4 million of funding for the projects.

The aquarium will use some of its money to expand its long-running education effort for students in Norwich, New London and Hartford, including classroom and distance learning, coastal field studies the students participate in and visits to the aquarium, all designed to boost awareness of the problem of marine debris in the Sound.

In addition, the aquarium will help educate its 300 stranding network volunteers about how to better identify animals in distress and how marine debris impacts them. Aquarium President Stephen Coan said that hopefully these education efforts will result in fewer stranded and injured seals, turtles and other animals needing to be treated in the aquarium’s animal care center, which Blumenthal visited Tuesday.

Coan credited Blumenthal with being a key figure in helping the aquarium move toward “a more aggressive stance” when it comes to conservation.

Blumenthal told a crowd of aquarium employees that the quality of the Sound’s habitat also is a reflection of “our quality of life.” He added that more broadly, it’s about “our obligation to be good stewards of our planet.”

He said the need for the aquarium to have an animal rescue clinic is due in part to the trash and debris that is being thrown into the Sound and the waters that flow into it.

He pointed out that reducing debris is about more than protecting wildlife, as the Sound is responsible for between $14 billion and $30 billion a year in economic impact. “When we degrade the Sound we’re not only injuring and killing wildlife, we’re harming ourselves economically,” he said.

Blumenthal added that educating people about the impact of marine debris “will help make sure we’re responsible stewards” of the Sound.
