Interactions
There are many different organisms in
aquatic
environments. One of the organisms that
brook
sticklebacks live and interact with are fathead minnows. In
a study done by Mark Abrahams from the department of Zoology
at the University of Manitoba, the presence of fathead
minnows resulted in stimulated growth in brook sticklebacks.
He says this may be because of decrease numbers of fathead
minnows in environments with Culaea inconstans.
Brook Sticklebacks are not only
predators as mentioned in the
nutrition section. They are also prey to many organisms
that live in the same environment as them. Some of
these
include birds, bigger fish, amphibians, and reptiles. Beside
being prey to these organisms, they are also vulnerable to
many insects. Some of the larger fish that eat brook
sticklebacks are brook trout, largemouth bass, smallmouth
bass, northern pike, and walleyes.
Herons, kingfishers, and
mergansers are a few of the birds that prey upon them.
