Cephalopod Capture Methods: An Overview
Cephalopods, including octopus, cuttlefish, and squid, are a major component in the marine biomass. Due to high behavioral diversity among species, uncertainty exists concerning the general applicability of sampling and capture techniques. This factor impacts on understanding of the overall abundanc...
