My favourite fishing spot, any tips?

I like to fishing here because it's nice, the current is not too strong, for fishing with lures (mepps spoons), and there's areas near the edge that have no current for bobber fishing.

However my catch rate is very low… In a few month I caught a chub and a goby… I go fishing every other day for about an hour in the evening.

Any tips to catch more fish? Like fishing hours, rigs, baits, bobber height etc

Thanks!
