Table 1 Dissolved oxygen and ammonia levels before and after oil exposures

From: De novo assembly of a transcriptome from juvenile blue crabs (Callinectes sapidus) following exposure to surrogate Macondo crude oil

   Dissolved Oxygen (mg l−1) Ammonia (ppm)
Crab CW (mm) Start End Start End
C1 15 5.9 4.13 0 <0.25
C2 33 5.9 2.11 0 0.5
C3 37 5.9 3.15 0 0.25 – 0.5
C4a 32 5.9 4.75 0 0.5
T1 17 5.9 4.27 0 <0.25
T2 28 5.9 1.6b 0 0.5
T3 44 5.9 0.55b 0 0.5
T4 31 5.9 1.45b 0 0.5
  1. Levels of dissolved oxygen and ammonia in each exposure chamber at the start and end of the 24 h static oil exposure. C1-C4 = control group; T1-T4 = treatment/oil group
  2. aIdentified as Callinectes similis following the oil exposure
  3. bBelow the 2.0 mg l−1 threshold used to define hypoxia in the Gulf of Mexico [21]
