Bigelow Lab in the summer found a record-low growth rate for plankton, a crucial food source.

In recent years, the researchers have measured a fivefold decline in the growth rate of phytoplankton, an indication of lower levels of the critical single-celled plants at the bottom of the marine food chain. Because phytoplankton are food for fish larvae, a lower abundance of phytoplankton could mean lower numbers of adult fish populations years from now, Balch said Based on measurements this year between June and September, however, the growth rate of phytoplankton is on pace to be at the lowest level since 2001.
