Residents throughout Hillsborough County, including Tampa, Temple Terrance, Plant City, and MacDill Air Force Base, can pick up free fish at a mobile fish event courtesy of Hillsborough County Mosquito Management Services. Residents must present a valid photo ID showing residence in Hillsborough County to receive fish. Limited quantities of mosquito fish will be available, while supplies last. The County is providing fish as an effective, natural way for residents to help reduce backyard mosquito breeding and control the spread of mosquito-borne disease. They require no feeding, and care is limited to protecting them from garden sprays, chlorine, or other chemicals used for cleaning. Mosquito fish do not lay eggs and require no special environment for breeding.
