Padro,
The Larval Fish Laboratory (Snyder and Muth) assembled a very rough video
displaying and demonstrating deployment of various type of gear used to
collect the early life stages of fish (particularly ichthyoplankton and
non-planktonic fish larvae). Gear include a "duo-net" (poor man's version
of the bongo net), and opening/closing conical ichthyoplankton net, an
ichthyoplankton net mounted on a sled, Miller sampler (small conical net
preceded by a long solid tube and mouth-reduction cone--for higher speed
sampling; improperly deployed in the video without a depressor), a 3-net,
opening/closing tucker-trawl, rectangular drift-nets anchored by line and
by stake, two types of larval fish light traps, a one-man fine-mesh seine
(1 meter square), and a fine-mesh dip net. The video was originally
prepared for Larval Fish Ecology shortcourses we offered several years ago
but continues to be used in a Fisheries Techniques course here at Colorado
State University. It is a bit long (31 minutes) and in need of serious
editing (we simply fast-forward through unnecessaryly long segments that
don't contribute any useful information).
The video was not intended for general distibution but if you (and others
that may be interested) are willing to work around its faults, a copy can
be ordered from our university's "Office of Instructional Service (A71
Clark Building, Colorado State University, Fort Collins, Colorado 80523).
I expect cost will be under US$25 including mailing. You can ascertain the
exact cost and ordering procedures through Ms. Claussen--email address

Larvae: Selected Gear" and has an Instructional Services catalog number of
TV05407.
