Can herring ever feel blue?

I fished Mandurah estuary today to chase some herring.

Although I managed to hook up a few of fish, fish weren't that switched on to chase my flies. I got them on a steamer but I had no success on a popper. There was one fish came up for it. It hit a fly once and it was gone. After that I didn't get anything even switching back to streamers.

Usually it is hard not to hook up herring when they are in their hunting mode. They get so agitated that they hit anything that moves around in front of their nose including a piece of red plastic straw or even bare hook.

It looks like even herring can be in a blue mood from time to time.
