Following a mini-review of crawfish aquaculture, the concentrations (mean in micrograms of analyte per gram of dried sample ± 95% confidence interval, range) determined by inductively coupled plasma-optical emission spectrometry of cadmium (0.49 ± 0.14, 0.34–0.79 ), copper (34.9 ± 5.3, 23.8–44.2), nickel (1.83 ± 0.54, 1.08–3.39), lead (18.0 ± 4.0, 9.9–23.), iron, and zinc (47.3 ± 4.6, 41.3–55.8) were relatively constant with a slight increase in iron (620.4 ± 205.8, 328.8–1072.8) in whole crawfish in a season of 4 months (February through May 2009) in Southwest Louisiana. The temperature of the crawfish ponds was monitored weekly but had no effect on the metal concentration in the crawfish trial. The copper and zinc concentrations in the crawfish pond soil decreased with increasing temperature. The other four metals showing no effect of temperature variations (increase). A comparison with a previous study showed no significant changes in the metal concentrations in the crawfish.
