The efficient collection of fishes from structurally complex environme
nts (e.g., coral reefs, kelp forests) is difficult because conventiona
l collecting methods generally cannot be used and many of the fishes a
re mobile and active. We describe the design, operation, and applicati
on of a diver-propelled net for efficiently collecting many species of
benthic fish that reside on coral reefs and on kelp-forested rocky re
efs. The overall size of the net and mesh size of the netting can be a
djusted according to the size and behavior of targeted species to mini
mize drag and damage to specimens. Altering these dimensions combined
with proper use of the net can result in a high rate of capture succes
s.
