Here is why , when fish are schooling and gorging on shrimp and pogy they burn as much as they eat !! Have you ever followed a school of fish ? They can move over 12 Miles a day !!

Colder month fish are not as mobile and eat slower and bigger meals and do not burn the enegry

Also fish sitting closer to the weirs over a givin time will likely be fatter depending on there movement compared to a trou up north ?


So saying fish are fatter or better health with weirs open or closed is not telling me anything

Unless you sit and catch every fish at weir !!


Trout move miles everyday

I can show you this summer when I caught 45 trout all soild 2-4lb trout and next day 45 dinks non over 3lbs on same spot same tide ?

The numbers are from 3 week periods of may-june over a 4 yr time frame.

Exacty you can not tell the health of the estuary with that data


Now don't get me wrong MG you are an asset to this fisheries I wish they would find you to do all our research

The data are from a three week window each year, so they indicate the health of the estuary during that time window and things that impact fish condition when assessed at that time of year.

It is possible that fish condition is somehow negatively correlated with weir openings when assessed in late May and early June, but that there is some mysterious factor that makes the relationship so strongly opposite the rest of the year that the data we are missing the rest of the year would overwhelm our seasonal snapshot?

Yes, it is possible. But it isn't likely.

By what mechanism would fish condition be negatively correlated with weir openings in May and June, and then suddenly switch to a strong positive correlation the rest of the year?

But it is a point worthy of some consideration and debate.
