All of our studies are in the same period each year (late May/early June). Seasonality can affect fish body weight, but we are comparing with the long term Louisiana average weights from the same time of year for each species.

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.
