In previous years, Struisbaai plaat has yielded very good catches for me. Mind you, this was when one was still able to drive on the beaches.
What I found used to work for me was to fish any likely looking areas and if nothing happened within the first couple of casts, I'd move on to the next likely looking spot. Best conditions were a moderate sea with no dumpers on the banks. Working sand was always a good sign.
I favoured the spring tide period as this is also the best time to collect bloodworm. Going to the plaat without bloodworm is an exercise in futility. I used fresh bloodworm bled and wrapped individually in newspaper to keep them alive and in a state of suspended animation(!). Keeping them in a cooler box is essential.
I used .40mm mainline with a .60mm leader exclusively. A running trace with the smallest possible swivels-Power swivels are ideal. Hook snoot was .62mm flourocarbon with a 4/0 or 6/0 daiichi 3111. Whilst that may sound too big, anyone who knows these hooks will understand that these are light,strong and razor sharp. The fact that I've caught many fish on them is good enough for me.
I found the larger fish of over 10kg to be more loners. Interestingly enough, when I've been fortunate enough to find the fish shoaling and where every cast has produced a fish, I've noticed that some of the fish have been literally stuffed with young black mussel. This make sense as these mussel banks are often exposed by wave action. The most notable example is the wreck to the right of the entrance to the plaat which can often be seen at low tide.
Make no mistake, a steenie will cut you off on these banks. Too thin a hook snoot is asking for trouble.
I will definitely be making an effort to target this awesome species again this winter. Maybe I should get a horse!
