Fig. 9. The respiratory responses of zebrafish Danio rerio pre-exposed to
hypoxia (PwO2=30 mmHg PO2) for 28 days
(unfilled circles) to (A) acute hypoxia (N=8), (B) hypercapnia
(N=7) or (C) sodium cyanide (N=6) compared to the responses
of control fish (filled circles, N=12 different fish for each
treatment). *Significant differences within the control or experimental
groups;
significant differences between the control and
experimental groups; two-way RM ANOVA (P<0.05).
