Redfish and Specks Benefit from Limited Weir Closings

[BuckingFastard]

saying its too large? have you seen the area behind the weirs? how far back that ecosystem goes? I cant imagine how many hundreds of thousands of acres are hidden from just the push of a button. theres also no proof that if someone catches a fish in turners that it couldnt have been attempting to feed at the jetties 2 days before that. the fish move!

great graph mathgeek and i think until there is a chip in every single fish that there is no better way to tell when the fish are being starved.

Yes, I do know how expansive that marsh is. I used to collect data for the coastal restoration projects and ran that marsh for 5 years. You are correct, the fish do move. I still think breaking the data into groups would give a more accurate representation for MG's hypothesis. Furthermore, in order to develop his theory, he would also have to take into account salinity, temperature, turbidity, etc...

true true

but im sure if he was getting paid to do these observations he would have so much info we wouldnt even wanna see it. this is all done because he wants to. i cant imagine if we paid him for the info!!

We are also computing correlations with every available environmental metric. So far, the biggest factors are the WEIRS and the OYSTER REEFS.

The effects of salinity and temperature are predictable. Fish that prefer saltier water (specks) have a slight positive correlation between salinity and body condition. Fish that prefer fresher water (puppy drum) have a slight negative correlation between salinity and body condition, etc.

But in most cases, whether the weirs are open is a bigger effect, and for benthic feeders, the health of the oyster reefs is a bigger effect.

Grouping the fish by where they were caught is not only problematic because of the degree of fish movement over several weeks, but also because anglers are notoriously inaccurate when reporting where fish were caught.

No doubt!! All the fish I catch are from Sabine!

BTW, kudo's to you MG for your efforts in gathering more data on the health of BL
