Except that you pointed numerous times to fish at the weirs likely being fatter because the weirs are open. Your argument this whole time has centered around his hypothesis not being true because you would bet that "fish at the weirs are fatter because of all the baitfish". that implies that the weirs are the reason for the fish being fatter because they concentrate the baitfish.

Thanks for posting the information from your study. Is it possible, and has consideration been given to the idea that the difference in condition of the fish during open and closed periods may be due to a change in WHAT they are feeding on? If for example open weirs provided easy pickings on shrimp so the fish avail themselve of it, but when the weirs are closed they feed more on menhaden and finfish, it could be a matter of the fish being thinner when the weirs are open becasue they are taking advantage of easy prey that is lower in nutrients verses eating more nutrient dense food. |

But thanks for the idea, we need to give more consideration to whether weir closures forces the fish to feed on more nutritional forage. |

How much influence do you think the seasonality of the opening/closing of the weirs have to do with it. For example, the weirs are more likely to be closed in July - August than in April/May. Obviously there are some seasons where fish will weigh more or less Did you compare same season openings/closures? |

The weir openings are more governed by salinity than season. For example, the average 30 day weir openings over our study period (same time each year) has varied from a low of the weirs only being open 15% of their maximum possible to a high of about 70%. Weir openings and closures in July-Aug do not impact our study at all, because all our fish are measured in late May/early June and we only consider the weir openings in 30, 60, and 90 day windows before each fish was weighed and measured. |

WC's
Doing great, had some WC's show up on my buddies lease in Sweetlake. LDWF found out they arrived, then banned my buddy from hunting his lease until the WC's left the area.

It's a shame they won't let him hunt his lease. I bet WC's taste just like chicken.

I tried listening but it kept cutting out and the audio was bad. I'll just wait for the minutes. They did have some discussion about changing rules to some state refuges but tabled the vote.

I've confirmed this with both the head of the whooping crane program and the Coastal and a Non-Gam Division Chief. All whooping cranes are fitted with transmitters, so LDWF knows where they are at all times. The pair currently using habitat on Gray Estate property are seen by hunters nearly every morning. This is the only pair near Sweetlake. |
