Anesthetic comparison. Treatment with MS-222 causes increased variability in blood glucose relative to treatment with cold water. Fish were fasted for 2 h before treatment. Glucose was measured with Meter B. MS-222: mean and standard deviation, 72.91 ± 39.21 mg/dL; coefficient of variation (CV) = 54%; n = 11. Hypothermia: mean and standard deviation, 60.18 ± 17.58 mg/dL; CV = 29%; n = 11.

Glucose tolerance test. Fish were injected with 1 mg/g glucose solution or vehicle. Glucose was measured with Meter A. Samples sizes: glucose-injected, n = 4–6; vehicle-injected, n = 3–7; noninjected, n = 10. ANOVA with Bonferroni's posttest showed no significant difference between vehicle-injected and noninjected controls for any time point. All glucose-injected were significantly different from vehicle-injected at p < 0.001, except that for 360 min postinjection there was no significant difference (p > 0.05). Data are mean and standard deviation.

Blood glucose response to fasting and feeding. (A) Fasting blood glucose at 24 h: CV = 30%, n = 35; 48 h: CV = 27%, n = 11; 72 h: CV = 31%, n = 25; 96 h: CV = 21%, n = 15. Kruskal–Wallis test with Dunn's posttest showed the following: 24 h versus 48 h, p > 0.05; 24 h versus 72 h, p < 0.01; 72 h versus 96 h, p > 0.05. Data are mean and standard deviation. (B) Postprandial blood glucose. Fish were fasted for 4 days, and then fed. Sample size is a minimum of 10 fish per time point. All fed groups are significantly different from fasted, p < 0.01; glucose at 30 min versus 15 min, p < 0.05; glucose at 45 min cannot be statistically discriminated from glucose at 15 or 30 min, p > 0.05. ANOVA with Tukey's posttest. Data are mean and standard deviation. Glucose was measured with Meter B for both experiments.

Glucose meter comparisons. (A) Two different glucose meters give different results. A blood sample was collected from individual fish, and each sample (n = 31) was measured immediately with both meters. A broad range of glucose values was compared by measuring fish that had been recently fed (beginning at 15 min postprandial) as well as fish that had been fasted for up to 8 days. (B) Blood glucose measured with pyrroloquinoline quinone glucose dehydrogenase (Meters B–D) using different sample sizes, compared with glucose oxidase (Meter A). Test strip sample volumes: Meter A, 1.0 μL; Meter B, 0.3 μL; Meter C, 0.6 μL; Meter D, 1.5 μL. Samples (n = 10) from individual fish were measured once with each meter. Order of meter use was randomized. Tukey's multiple comparison posttest revealed that Meter B versus Meter C was not statistically significant (p > 0.05). All other comparisons were significant at p < 0.001, except Meter D versus Meter A was significant at p < 0.05. Data are mean and standard deviation.
