It's a pretty safe assumption that the feral jags in Florida (like all of the other invasives) came from either hobbyists or commercial fish farming. They're not native there.
The destruction of the Everglades is a tragedy and one that will have real negative impact on people and the environment.

Colin Apse is Senior Freshwater Conservation Advisor for The Nature Conservancys Africa, Great Rivers, and Eastern U.S. Freshwater Programs. He has over a decade of experience at TNC working on freshwater ecosystem conservation and sustainable water management solutions. He is motivated by the belief that managing our scarce freshwater resources to meet rapidly growing human needs without sacrificing the biodiversity and critical ecosystem services of lakes and rivers is a core environmental challenge of the 21st century.
In Africa, he is currently supporting fisheries and watershed conservation efforts on Lake Tanganyika as part of an integrated human and environmental health project focused around Mahale Mountains National Park in Tanzania. Colin is also advising the creation of the Upper Tana-Nairobi Water Fund, designed to deliver payments for the watershed stewardship upstream of major water users.
Colin also supports for the Conservancys Great Rivers Partnership, which seeks to advance integrated river basin management across the globe through targeted investment in collaborative river basin projects and facilitation of an international exchange network. Colin co-led the development of a conservation blueprint for the Magdalena River Basin in Colombia - one of the Partnerships Great Rivers - now being used as the basis of a major conservation and development collaboration with the Colombian government.
Much of his work in the United States focuses on developing strategies and policy approaches that balance human water use and environmental water needs such as fish passage and adequate flow - at state and river basin scales. Colin cas served on technical advisory committees on sustainable water management reform in Connecticut, Massachusetts, Vermont, Pennsylvania, and in the Delaware and Potomac River Basins. Colin recently finished leading the Northeast Aquatic Connectivity Assessment Project, a collaborative across thirteen states which prioritized opportunities for dam removal or mitigation based on modeled ecological benefits. This work is now expanding to the Chesapeake Basin and Southeastern U.S. states to help give us a picture of fish passage priorities for the U.S. Atlantic coast.
Colin received a B.A. from Duke University and a Masters degree in environmental management focused on aquatic ecology from Yale University. He lives in Portland, Maine and works out of TNCs Maine Chapter office in Brunswick.
