Prawn runs

Gday all,

This might sound like a stupid question to you seasoned fishers, so forgive me.........20 odd years in the desert, I need some educating.......

Hopefully in the next couple of months we are moving to WA (Northampton) and have heard they have a prawn run near Kalbarri somewhere.

Could someone please fill me in, what exactly is a prawn run, when they happen and tides  etc?

Any secret places and info would be greatly appreciated.

 

Cheers
