The research ndings indicate that sh presence drives zooplankton biomass down and changes species composition but does not signi cantly a ect overall zooplankton diversity or mean numbers of individuals. Lakes with sh tend to have a diverse population of smaller rotifers and lower numbers of larger zooplankton (e.g., cladocerans or copepods). On the other hand lakes without sh support a greater diversity, abundance, and biomass of cladocerans and copepods. Bluebird Lake with an impressive natural barrier to sh movement maintains the biggest zooplankton population found in the survey. Two lakes, Bear and Pear, stood out as having very diverse and somewhat larger zooplankton populations than other lakes with Fish E ects on ZooplanktonThe Question: Assess the impacts of past sh introductions on zooplankton communities.The Results: Fish introductions negatively impacted zooplankton community structure.
