A Biochemical Genetic Evaluation of the Northern and Florida Subspecies of Largemouth Bass. Trans. Am. Fish. Soc. 112, 1–20 (1983) More recently, Philipp's research has focused on the effects of fisheries interactions and environmental stressors on reproductive success, physiology, behavior, and survival of fishes.Cooke, S.

Behavior and mortality of caught-and-released bonefish (Albula spp.) in Bahamian waters with implications for a sustainable recreational fishery. Biol. Conserv. 118, 599–607 (2004) Philipp's research revealed that populations of largemouth bass, ''Micropterus salmoides'', in most of North America composite a separate species from the Florida bass, ''M. floridanus'', in Florida, and that stocking programs introducing Florida bass outside their native range have detrimental genetic effects on largemouth bass populations. Another research program showed that angling targets individual largemouth bass with certain behavioural and physiological characteristics, and in the process can cause evolutionary change in populations including reduced parental care and reproductive success, as well as reduced angling success rates.

Conservation activity

Philipp is a co-founder and Chair of the Fisheries Conservation Foundation, a nonprofit organization founded in 2003 to promote the work of aquatic scientists, environmental professionals, and resource managers to policy makers and the public to ensure the sustainability of freshwater and marine ecosystems through well-informed management practices. Specific campaigns include: Flats Conservation, Rivers of Success, Shark Conservation, Coastal 2100, North American Black Bass Coalition, and Responsible Angling, which promote awareness and conservation for a wide range of environmentally and economically important fish species and habitats. The Foundation is also highly involved with conservation initiatives in The Bahamas, with projects including the Bahamas Flats Fishing Alliance that aims to assemble multiple stakeholders to promote the conservation of valuable flats fisheries, and The Island School Poster Series, which engages high school students in important current environmental issues.
