Hi Gary,
we used polyamide particles from Dantec Dynamics (
http://www.dantecdynamics.com/seeding-materials) to measure fanning
currents by nest guarding male Round Goby. Not really "organic" but these
worked well for our application (see paper HERE
<http://lofe.dukejournals.org/content/3/198.full.pdf+html>). I think Dantec
also carries hollow glass seeding particles.
Dr Breithaupt at University of Hull in the UK may also have some good
advice for you. He has a lot of experience using Particle Image Velocimetry
in the field of aquatic biology.
Hope this help,
