There's definitely a very strong correlation.
The redfish are staying further to the north. We know temperature is a factor. I've been to most of the assessments, up until the last one. We know that there's particularly juvenile shrimp in the bellies of these redfish. They're just getting at the size now where they're going to consume shrimp even at a higher rate.
There's another telling factor with the surveys. Basically, the estuary is the smallest area in the gulf. I'm sure everyone here is familiar with it. If you look at the overlap of redfish and shrimp from that survey, basically the only place where the shrimp are holding their own is in the estuary. That's the only place in the deep waters of the gulf where there are no redfish. For whatever reason, the redfish don't want to inhabit there. That's from DFO's own work.
That's a very telling picture to me. It's hard to argue with that correlation. There's no doubt about it. I don't think there's a doubt in anyone's mind that redfish predation is the single biggest factor in the decimation of the shrimp resources.
