Lobsters, crabs, squid, and other invertebrates are becoming more common while populations of bottom-feeding fish are plummeting, according to a long-term trawling study of Rhode Island's Narragansett Bay.

The study also shows that small, warm-water species have increased while larger, cool-water species have declined.

Scientists from the University of Rhode Island (URI) say rising sea temperatures linked to global warming is the primary cause of shifts in the abundance and types of species living in the bay and adjacent Rhode Island Sound

And "these types of changes are probably widespread," said lead author Jeremy Collie...
