Letter: Herring has keystone role in marine food chain

Thank you for the excellent article on herring runs in Southeastern Massachusetts (“Herring back in promising numbers,” April 29).

You wrote a very interesting, comprehensive piece. I was especially pleased with your coverage of the Weymouth herring run, including Scott Dowd’s comments on the ecological and economic importance of river herring. Most people think of herring as an important food source only in Colonial times; they do not understand their importance today in the marine food chain.

Articles such as yours help educate the public about river herring’s keystone role in our marine fisheries affecting both those who fish for a living and those who like to eat fish (and even those who don’t, I would think, because if there aren’t enough fish to eat, pressure is put on other food supplies).
