Hi Mike!
Long time, no see. How are things going for you?  What kind of a project 
are you doing with the pipefish?  I actually have alot of experience 
with catching pipefish in Miami using a seine.  Eric and I used to catch 
them by the dozen right on the beaches off Virginia Key and Key 
Biscayne.  We used a small seine (about 6 feet in length, and about 3 
feet high), with a mesh size of about half a centimeter.  You really 
don't want much larger mesh size than that, because they slip though 
very easily, especially the little guys.  The lead on our leadline was 
minimal and we still had great catches- I don't think you need to worry 
about having a super-heavy leadline.  Also, we found that rather than 
moving in a smooth, fluid motion, as you would want when trying to 
clean-sweep an area, it helps if you bob the seine poles up and down 
(just an inch or 2) as you move along, because this seems to help 
dislodge the fish from the grass.

One other pointer- as far as keeping them in captivity, they seem to do 
best with live brine shrimp, as many pipefish and seahorses will /not/ 
eat frozen shrimp.  But brine shrimp alone are not nutritionally 
satisfying, so you may need to throw frozen mysid shrimp in every now 
and then.


Eric and I are actually heading up to RI, starting tonight after work, 
for our wedding this weekend.  We will be on the road for the next 2 
days- so if you want to call me and get any other details, feel free.  
My # is the same as before - 305-467-8998.


Good luck!
-Vanessa
