Does anyone know anything about carp? Like if they have any local predators, and whether it's normal to see a (school? pod?) of twenty or so of them in the Charles River?
Once, James bought a Magicarp off a vendor on a boat, and Jesse was really angry and said that was a stupid useless Pokemon, but at the end of the episode, when the boat sank, the Magicarp saved Team Rocket, so it wasn't so useless after all. But that probably doesn't help you so much.
Hurm. Big carp are bad--typically Asian imports. There are predators but they need underwater vegetation to hide in but even so they get too big for most of them. They're getting to be endemic in the Great Lakes. I'd be surprised if anything in the Charles would be able to tackle them.
According to this: COMMON CARP Cyprinus carpio Linnaeus, 1758 DISTRIBUTION AND ABUNDANCE: Introduced. Common carp were first distributed in Massachusetts by the U.S. Bureau of Fisheries in 1880. Today, carp are found in many areas, particularly the Merrimack, Concord, Connecticut, Taunton, and Blackstone river systems, and in a number of larger lakes and ponds. Carp are at times very common; over 20,000 were killed by dropsy (caused by a Aeromonas bacteria) over a short period of time in the Merrimack River in the late 1970's. Our records probably underestimate the range and abundance of this species since it is normally not taken with small seines and electrofishing gear used during our surveys
Here's what http://www.carp.net/faq has to say on the subject: They do sometimes go in schools They were introduced to the US in 1877 They are bottom-feeders living in lakes, ponds, and rivers Normal carp (for fishing purposes) are "a large omnivorous fish, yellow-green and brown in color." The red and gold and black ones are Japanese Koi carp.
The exceedingly poorly written faq also states: "According to my references and consistent with Carp-l's observations carp move into the shallows as Spring water temperatures rise. They wallow around for awhile in large groups, but then break up into breeding groups (usually more males than females). The breedinggroups thrash around with the female depositing eggs which drift freely until they attach themselves to some object on the bottom (they are adhesive)."
It is the eggs which are adhesive, I believe.
At a guess, you saw a breeding group of fish which are in the area year 'round, but rarely close enough to the surface to be easily spotted.
