Just my 2c on the matter of LGF going of the bite at Roodeplaat. On all the occassions that I fished Roodeplaat (not only the recently found honeypot/hole) when the wind starts picking up them LGF's just dissappear entirely, not even to be found in the deeper water, where they go to is anyones guess, but it happens in a matter of seconds rather than minutes.
As for the presence of mermaids at the last three trips (honeypot) they're always there, large numbers and large sizes. They (the mermaids) seem to occupy the southern and eastern bank/parts of that bay, although I've seen some swimming around in between where the LGF's where holding out. Having said that, I still didn't have any trouble catching LGF with the Mermaids so close by and in such numbers, not even when they swim where the LGF's are holding up. My take on their dissapearance and going OFF the bite is mainly the wind, but more importantly the direction in which it's blowing (as long as it clears the surface from the green algae where you're fishing) then you'll still manage to get some but not as many as when the wind doesn't blow and the water surface and column is clear.
Again, it the surface is cluttered with the algae, and there's now wind, you can leave the place and rather go look for a place where the water's surface and the water column is clear.
Also, structure plays a role but not as huge a role as would be expected as normal (seasonal and other contribution facts ) LGF behaviour, anyhow hope this helps in understanding Roodeplaat a little better, keeping in mind that, that piece of water can turn on you, bite you right in the BEE hind and do so in minutes, but when it plays nice, the rewards are sooooo worth the efforts.
