Change in carapace size of female dungeness crabs after molting.
Description
Data collected from a study of the change in the carapace size of female dungeness crabs (Metacarcinus magister) before and after molting. Crabs were either captured prior to molting and then allowed to molt in captivitiy, or were re-captured after being measured and tagged. See Nolan and Speed (2009) and Hankin et al. (1989) for details.
Usage
dungcrabs
Format
A data frame with 472 observations and four variables:
- presz:
carapace size (mm) before molting
- postsz:
carapace size (mm) after molting
- year:
fishing season for captive crabs
- source:
source of crab (re-capture or captive)
