I would like a discussion about berley. Few days ago, I went near foul on the seaward side of Tiri Island. Anchored about 50m from foul, incoming tide, relatively weak current I thought (due a small tide). Started 1.5hrs after low tide. Berley down. Fishing 2 rods with single hook, bait, cast down-current towards the foul. No bites immediately. After about 30 minutes, bites started. After an hour, caught a 30cm snapper. After about 1.24hrs caught a 32cm, after 1.5hrs caught a 38cm. Then bites reduced, after 2 hrs virtually no bites, an occasional perfunctory tug.  

a lot will also depend on the taste (smell) of burley being used.
Mussel burly dosnt work as well near the mussel farms but kina burley works great.
Just as we feel less hungry in winter and tend to have shorter meals (time wise) I think the snapper are similar so using a general burley that works in spring/summer may be less tempting in winter?

May be just another of my weird ideas but hey, works for me

Generally  know you are sending the burley out right after 10 to 20 mins... when the 1st legal fish come in...30 mins get good fish
BUT this depends  are the fish on the bite?
Are u directing burley trail down to where fish actually are?
Is it falling thru the water column in a manner to bring the fish to where your lines are out the back?

And a wobbly pot doesnt work unless u are in some rather heavy swells.. in in carm waters a lot of bring up 1/2 to 1 m the drop 4 or 5 times to keep sending a consistent trail out.

Then water temps to consider...
I make our own burley put into 2L milk containers...and freeze.. I find 1 bomb lasts ideally between 30 to 40 mins...depending on current and water temp depends I I chop the whole container off or chop ut 1 or 2 sides

Most of our fishing is drift....and find drifting with a burley down is very effective on long drifts

 Also wobbly pots.. expensive to loose....
For a elcheapo collasable.. a plate of scrape steel around 150mm diam.. 3 or 4 holes around the edge.
A $14 black burely net...split it and re weave into tubes...tied at the bottom... makes 2 pot nets
drop the plate in , cable tie in each hole... and thread 2 or 3 about 10 gauge wire thru winding the ends to form a circle to keep the net shape.
Or something like a BMW suspension spring.. chop the top ring, the bottom of the spring is smaller and acts as a base.

Also dont use ropes to suspend the pot... in current far too much resistance and hangs way out the back... messing up lines or requires big weights to drop down.
 2.5 or 3mm braid from the haberdashery shop...about $45 for a reel of about 300 or 400 m  (forget length)
 Reel...$20 electric extension lead drum from mitre 10.. but keep washed and lubed with CRC or similar or after a few seasons will rust in the hub.

Some interesting replies.

Hey Bazza. Thanks, truth in what you say. Do you know when the fish are going to be back on the bite; if so, please let me know.

And just a last point re the depth.
