Freshwater can be a patchy place to fish but you can increase your chances there by gaining a little bit of local info.
First thing you should know is that there is a chalk bar ( the original cliff line ) that runs along the mouth of the bay that almost acts as a barrier to bottom feeding fish like rays and sole ect, who just swim along this barrier oblivious to fact that the bay even exists. This puts a lot of people off fishing there.
Wrasse can be caught all day long from pretty much any section of the bay but the middle of the bay by the 2 slipways is favored because of the easy fishing and the deeper water.
After dark when all the sunbathers have gone home is the best time for all the other fishing.
Rockling ( of quite a few different varieties ), pout, pollack, eels ( large and small ) dogfish and an abundance of small blenny type fish can be caught pretty much all year round but they will plague the more discerning angler who doesn't up their hook size.
Most anglers `in the know` who visit the bay from september until january with be on the hunt for bass.
Large baits of either mackerel or whole squid fished no further than 20ft out using a running ledger seems to be the way to go.
I have known of many double figure bass come out of the bay over the years and some very experienced anglers who have been `smashed up` by some very large fish.
Again, fish around the slipway area to get into the deeper water.
For the more adventurous, try fishing the ledge on the eastern side of the bay. Even at high water the ledge gets no deeper than 4 or 5 ft but many bass have been caught there in calm conditions, though use one rod because tackle losses may be high.
