Dear Dan we are working on this - and it is a fascinating problem here in Greece especially with the difficulty we had in developing a nation-wide IBI.

I am sorry we do not have the data available yet but we have on PhD student working on this. I wish you all the best and would love to have you guidance on this - I can send you a message sometime in the near future.

The index intercallibration reports and our recent paper are linked in this blog post:

Here's one from last year.

Hi Dylan, thank for the paper. Josh Korman and friends do some really good work evaluating and accounting for fish detection.

Thanks heaps!

Hi Stamatis,

Thanks for the response. I will send you a message and we can discuss further if you like.

Dan

I have literature abou fish stock estimation by electroshocking in LakeKinneret and the newly created shallow lake Agmon in the Hula Valley (Israel)

Hi Moshe,

What you have may be perfect. Does the stock estimation include estimates of catchabiltiy coefficient or detection probability?

Thanks heaps,

Dan

For anyone else interested in the question of patterns in detection using electrofishing, I just want to highlight several recent papers that I think are really good. Hope you enjoy and are inspired to comment on any others that you may know about......particularly any evaluations that may be buried in hard to access reports. Thanks!

And one with the title

"Sampling the stream landscape: improving the applicability of an ecoregion-level capture probability model for stream fishes"

that I don't see on research gate, but can be found at http://www.nrcresearchpress.com/doi/abs/10.1139/cjfas-2016-0422#.Wl131FWWaUl

Try this one:

Bayley, P. B. & D. J. Austen, 2002. Capture efficiency of a boat electrofisher. Transactions of the American Fisheries Society 131:435-451.

Catch probability is high

I would like to suggest the name of Prof. K P Biswas email:[email protected] in this regard. He is an expert in the field. He may be highly helpful to you.

We estimated detection probabilities for boat EF and hoop nets for sampling Burbot.

Thanks Zachary, this is one I didn't have.

Cheers,

Dan

Here is another.

Schloesser et al. 2012. Heterogeneous detection probabilities for imperiled Missouri River fishes: implications for large-river monitoring programs. Endangered Species Research 16:211-224.

Zachary, this is another good one that I wasn't aware of. Keep them coming!

We estimated the detection probability and "occupancy" from unmarked individuals for multiple species across multiple seasons for both boat electrofishing (AC current not DC) and seines.

Hi David,

Thanks so much for the paper. You have put out a number of good papers dealing with fish detection. I enjoy your work.

Cheers,

Dan

Thanks. I am looking forward to seeing what develops from your efforts.

What´s the electrofishing?

See INCDPM raports about electrofishing in Romania.

Hi Dan,

maybe you want to check the attached document of a colleague of mine ('Technical bais of electric fishing'). It is in German, but the literature sources might be helpful.

Best wishes
