What is quantum yield (Fv/Fm) on the BW680 Ballast Water Handheld Fluorometer?
Summary
Definition of Quantum Yield on BW680 Ballast Water Handheld Fluorometer
Answer
Quantum yield is the ratio of Fv/Fm and estimates the health of the species in the system that photosynthesize, such as phytoplankton. Fv/Fm = 0 is dead, Fv/Fm of approximately 0.6 is healthy, Fv/Fm <.25 is non-viable (will not likely reproduce), Fv/Fm >0.25 is viable (will likely reproduce).
