Hello everybody,
I aim to study night activity of atlantic salmon fry in a field experiment.
Because I want to measure activity at the individual level, every fish used
in the experiment will be individually tagged using VIE tags (Visible
Implant Elastomer, http://www.nmt.us/products/vie/vie.htm). Such tags are
highly visible under low luminosity conditions when fluoresced with blue
light and amber filters.
However, in a laboratory experiment I found that atlantic salmon fry were
highly disturbed when illuminated with such light. I contacted the
fabriquant and they said to me that this problem can be resolved using UV
lamps.
I've got two questions:
-Has someone ever used such kind of UV lamps? Is it really
possible to fluoresce VIE tags with UV lamps?
-Where can I find waterproof UV lamps?
Moreover, if someone used to do underwater observation by night, I would be
greatful for any advice!
I look foward to hearing from you
