Effects of Salinity on the Reproductive Cycle of the Mangrove Oyster Crassostrea tulipa in Hatchery Conditions

Figure 2

Condition index of mangrove oyster Crassostrea tulipa. (a) Condition index of oyster before spawning (BS) and after spawning (AS/T0) induction and after 40 days (T40) in each tested salinity (40 (S40), 35 (S35), 30 (S30), 25 (S25), and 20 (S20)) in experiment I. (b) Condition index of oyster after spawning induction (AS/T0) and after 40 days (T40) in each tested salinity (S40–30, S20–30, and S30) in experiment II. Boxes represent quartiles, the thick line within boxes represents the median, the whiskers show nonoutlier range, and open circles represent outliers.
