>>681433with the leach cast out at each of 30 60 90 120 150 degrees, get as far as you can, let sink for 5 seconds and then start doing fast jerky strips. If you hit all 5 angles and no bites move along shore 25 yards and repeat. If you are casting to a specific fish cast beyond the fish so it goes past him.

Sea Trout are basically just brown trout in the end. All brown trout I know are active from about dusk til dawn. I'd guess a sparkly pink and translucent white shrimp found these pics and this guy gives instructions on how to tie here (they look pretty easy)... try pink-reddish orange egg patterns too under a strike indicator:
