A 19-day experiment was conducted to investigate the optimal light intensity and photoperiod combination for larval swimming crabs Portunus trituberculatus in terms of survival, development, and apoptosis-related gene expression. Two photoperiods, i.e., 12 and 18 h photophases, and three light intensities, i.e., 126.08, 173.17, and 191.53 μmol m−2 s−1, were used in the study. The results showed that the cumulative survival rat...

An eight-week experiment was conducted to evaluate the effects of eight light intensities (0, 0.83, 1.61, 8.17, 15.89, 31.38, 63.69, and 124.31 μmol m -2 s -1 ) on the survival, growth, antioxidant, molting-related and apoptosis-related gene expression of juvenile swimming crab Portunus trituberculatus . The results showed that the survival rate of crabs was the highest under the light intensities of 8.17 and 15.89 μmol m -2 s...
