I fished Hanningfield yesterday with a Mate from a boat, the fishing was really hard, albeit, not because of the terrential rain and wind.
There were signs of algae in the water, and no matter what, every time I cast my flies out they came back with green algae on them, whether using a team of buzzers / wets or Boobies on a Di7.
We managed a fish apiece and fished hard all day long and was the last boat too leave.
The algae was not like what I have seen before, it seemed to stick to your line and then clump up like a sponge and was quite hard to remove, see pic below.
I'm sure the slightest wiff of this stuff put the fish off!
