Of the collecting methods used at Cocos Island, Costa Rica, dredging and
tangle nets yielded the best results.  The tangle nets brought in
Chicoreus eversoni, Latiaxis santacruzensis, and Haliotis roberti.
Dredging operations brought in Cancellaria gladiator, Morum veleroae, and
a new species of Pecten (Euvola).
 
The nets were not baited. Two of the four nets were stolen by nearby
shark-fishing boats and a third was hopelessly tangled in coral.  The
1' x 1' x 6" dredges used were of an ingenious design developed by Dave
Mulliner and Paul Skoglund which included a no-hands lifting mechanism.
There are few West-Coasters who dredge who do not use the
Mulliner-Skoglund dredge. Anyone who would like details of the dredge
design and 'lifting' mechanism can email me.
