Biological field techniques for Chionoecetes crabs

"This important publication enables standardization of data collection by fisheries observers and shoreline samplers, crab and shellfish biologists, and fishermen. Wide use of the book promises to improve data accuracy, and thus promote good management for these commercially important crabs. When data are collected citing this publication, there should be little or no ambiguity as to measurements made and definitions used. This guide is not all inclusive, but is intended to identify structures and organs, measurements and descriptions, and techniques that are commonly used in field studies"--Page vi.
