Effects of Different Light Spectra on the Growth Performance and Survival of Largemouth Bass (Micropterus salmoides) Larvae in Recirculating Aquaculture Systems

The effects of light-emitting diode (LED) spectra on the survival rate and growth performance of largemouth bass in the nursery stage were explored in this study. By means of recirculating aquaculture systems, largemouth bass larvae (initial body length of 6.5 ±0.23 mm) were reared under four different light spectra: blue (half-peak bandwidth = 429 to 450 nm), green (half-peak bandwidth = 503 to 535 nm), white (320
