Abstract: I conducted a study to establish the appropriateness of caging as a method to estimate growth rates of juvenile speckled sanddabs, Citharichthvs stigmaeus, and to compare those growth rates within and between the open coast of Monterey Bay, California and a local estuary, Elkhorn Slough. I compared growth rates of individuals constrained in cages for the duration of the comparison. The study was conducted at four sites, with four replicate cages in each site of four fish in each cage. Two of the sites were located along the open coast of Monterey Bay, while the other two sites were located in Elkhorn Slough. Fish were only recovered from the two Elkhorn Slough sites. Only at one site were significant differences in growth rates between cages detected (P=0.03). Using cages as replicates, I did not detect a difference in growth rates between the two sites. These results are discussed in terms of alternative caging designs as well as hypotheses to account for the observed patterns in growth rates.
