Wild Trout Designation Evaluation: EFish Survey
Permalink  
 


PCT took part in a electrofishing survey this week led by the DFG's Heritage and WIld Trout  team. Several PCT members served as volunteers each day netting fish and collecting and recording data. A good time was had by all in spite of the hard work. Lower, Middle and Upper sections were surveyed with increasing numbers of fish captured as we went up. Most of the fish were small, but there was a fair number of fish in the teens and a few over 20", just as one would expect from recent posts on the forum. H&WT was pleased with the result which was designed to produce a baseline measure of the age and size distribution: appears we have a sustainable WT fishery if we treat it right. Attached are a couple of action shots at a couple of sites-feel free to guess where we were and name anyone that looks familiar to you. I encourage the volunteers to share their experiences as long as tthey don't give away the new "sweet" spots.

If you are interested, we will be involved in additional surveys. To volunteer you must be a member of PCT, so here's a good reason to join and get involved.

I helped the Heritage & Wild Trout crew on Tuesday & Wednesday morning; what a great bunch of people involved!

I learned many things on those two days. Most important of all is that electricity, water and people do not mix well. Ask Alistair about that.

Another interesting fact I learned was a definitive way to tell stocked trout from wild. Stocked trout have a slight dip mid way up on the leading ray of the dorsal fin, wild fish do not. The leading ray on wild fish is straight as an arrow. Apparently every other indicator we use to ID stocked trout, namely the pale coloring and beat up fins is not reliable. Both the coloring and fin shape on holdover stocked fish will change over time.

I thought that looked like Alistair standing on the rock. You guys find any trout with lures or flys attached?

Here's some more shots from Day 3.  What a great experience!!  The Heritage and Wild Trout team appreciated all of the volunteers who came out.  I learned a lot of little things as well in getting a chance to converse with their crew.  The variation of size and age of the fish, especially the younger ones, demonstrated a sustaining population of wild reproducing fish on Putah, which was a very positive sign for this progam.

Just for imformational purposes, by the middle of Day 3, Alistair had been re-promoted to netter after his "shocking" experience of Day 2.
