How can they disappear so suddenly?


There were millions of shrimps in the river last Saturday.  They were so thick that the water had turned into a creamy shrimpy colour.

This week?  We were only able to spot a couple of them hiding among weed beds.  How can they all disappear like that?

We went to the same place, hit a similar tidal stage, and wind direction was pretty much identical too.  All variables seemed to be as they were last week, yet those shrimps weren't there anymore.

Well, the world on the river is really amazing after all, and we can only grasp a small part of the whole mystery, I guess.

Fish were still hitting on a shrimp pattern even though the shrimp fest was over, but all fish were quite small.  I also caught a flathead on my prototype clam worm / sand worm pattern which was good for a change.

Was the water more or less salty than previous visit?

Hello

The direction of wind was different, as I remembered.

I don't know if the level of salinity in the river can change greatly over one week, or how much of change will affect shrimps.

All I know is that shrimps come in a great number from time to time, which can drive black bream into a feeding frenzy as we can imagine.

I don't know if it has something to do with the salinity or water temperature, as I see big shrimp balls at any time of year.
