Figure 3. Percentage of female specimens of Palaemonetes pugio that became ovigerous during a 77-d multiple-brood study of cyclic hypoxia (1.5 mg/l–8 mg/l DO, 4.20–18.88 kPa); n = 25 shrimp/treatment. HH—males and females continuously exposed to cyclic hypoxia. HN—males and females exposed to cyclic hypoxia 14 days prior to mating but allowed to mate in normoxia (8 mg/l DO). NN—males and females continuously exposed to normoxia.
