I would be careful with this, I think this could be illegal on two counts:
1.
Bait
It is illegal to (or attempt to) deposit or release into, or within 30 metres of, any waters:
live or dead bait or baitfish, including fish eggs, gametes or fish parts
2
Chumming
Chumming (baiting an area to attract fish) is allowed for common carp and for attracting other fish species, but only with plant-based baits as defined in general fishing regulations.
