I've using salted pilchards, but not sure if they're too old for them Breams and Tailors in the rivers are still taking my salted pilchards though. Not sure if the sambo are more picky.
I fish Narrabeen beach. My problem is I can't identify gutters. And it seems that every time after I've tried to cast as far as I possibly could, my line, bait and all get washed back up closer to shore :-( And I was using the heaviest star sinker that I could cast
Gutters are simply channels that are deeper than the surrounding water. A bit like an under water creek. They can run parallel to the beach or at 90 degrees and any angle between.
They are usually darker because they are deeper.
The most common way to spot a gutter is to watch the waves...Waves break in shallow water. So when you see waves breaking with a gap between them, there is a gutter. Like wise you will often see waves break a fair way out then stop and re-form closer in which indicates a parallel gutter.
I am not sure about fishing for salmon at night. I think it is better at sun rise and sun set, but you can catch them any time of day.
This might help...There are plenty more on Youtube but this one is short and to the point.
itsaboat mate...Life is just a boat and then ya marry one !
I've watched this one and several others, but when standing in front of the wave I get confused by what I'm seeing . I supposed I'll just have to keep trying and will eventually figure it out through trial and errors, having already watched those videos.
