1. Boat crew (Two minimum, five maximum):
Net crew: One or two lifejacketed people. Load the net on the bow, pay it out as needed, keep lines secure.
Optional spotter watches for rocks.
Boat pilot: Pilot makes certain of tow site, keeps track of currents, crew and boat safety.
Optional recorder takes water temperature, GPS net set, gives data to seine recorder.
2. Beach crew (Three minimum, no maximum):
Two net pullers, one on each line. Net pullers may also work the net once it’s pouched.
One – two net handlers to stand outside net zone to remove rocks, pouch net (see below).
Recorder takes air and water temperature, records the time, records the GPS of the net set, photographs the catch, records bycatch and fish measurements, notes birds, mammals, number of participants, and any other pertinent data.
Crew boss, if present, assigns positions as needed and reminds people of their role. Encourages calm inquiry.
Education liason, if present, keeps onlookers informed, recruits more crew at the drop of a hat.
Fish manager, if present, monitors humane handling of fish, keeps track of which fish have been measured, lavaged, photographed, etc, keeps tubs & buckets full and aerated.
Lavage team, if present, establishes a calm zone for gastric lavage only.
3. Protocol
Load net onto boat bow.
Establish tow location.
Bring equipment to tow location on shore, fill buckets half full of water and line with nets, have dip nets ready.
Boat places net
Five minute wait to allow fish adjust to net. Bring net lines, downcurrent one first, to net crew on beach.Net crew brings net in to a pouch.
Pull lines so net comes in evenly. When net is close to shore, walk towards each other while continuing to pull. In case of a rock in the net, DO NOT wade into the net pouch, but fix it from outside the net. When wading is possible, adjust spreader bars to a Vee position. Immediately, pull lead lines to pouch the net, while simultaneously bringing the spreader bars together. Pouch should form in deepest water practical to avoid fish damage. Throw crabs, seaweed, etc out, and report number and kind to recorder.Transfer fish to buckets. Use a separate bucket for larger sculpins or sharks.
Inexperienced net crew method: Use soft mesh dip nets Better method: Standing outside of net, shake ends of net to center, throw unused net lengths over floats. When fish are concentrated in a small pouch, pour it into bucket.Divide fish into lavage candidates and measure-and-throw-back candidates.
Measure all fish, identify and record. If there are over 100, measure first 20 of each species. Photograph a specimen of each species. Release beyond wave zone.
Lavage candidates go to calm zone (see lavage protocol (not yet prepared)) where they will be measured.
When recorder and crew boss both give the go-ahead, tidy up.
