<font color='#000000'>Best suggestion I can make is to blag some used oil from a chip shop or catering estabishment.It is sent back in 5 gallon drums for recycling as the water content rises etc. Or buy some cheapest cooking oil from a supermarket like Lidl or Aldi. Add a bottle or two of Pilchard oil.Fish are probably like sharks and are incredibly sensitive to attractants something like one drop of blood in a swimming pool or suchlike. And/or marinade a few chopped up mackerel in it.</font>
<font color='#000000'>Cheers, I tracked down "shark special oil" + "concentrated sardine oil", both around £3/lt, from sharnbrook tackle but I know it is available in larger quantities - somewhere.</font>
<font color='#000000'>We use it for sharking, but at this time of year I make up large quantities and freeze it down. This means no messing around trying to catch mackerel, all we need are a few baits and we're ready to fish. I used to get 5l containers for £6.50 but that source has dried up.</font>
<font color='#000000'>Think how oily a mackerel is and they freeze ok. Freezer's at -26 and all is fine. Went out today to collect some mackerel but it has slowed up a bit. Small tide though and not much else biting, 1 pollock about 4kl and a few very small codling.</font>
<font color='#000000'>After a good mackerel-bash keep the heads & guts & freeze. Likewise any old unused bait. Once slightly defrosted they'll go through a decent mincer easily without gallons of mess everywhere. Stir in some cheap cooking oil, leave to fester for a few hours then re-freeze, in handy dollops. Looks disgusting (a bit like cat spew) but does the job.
If winter beach-fishing for whiting, take some with you & at LW bury a few small "portions" 6 inches down in the sand in a line back up the beach to maybe 50yds out from HWM if you're staying till then. The surf churns up the sand to this depth & releases it as clouds of small particles. Deadly for whiting, unfortunately more so for dogfish. Using this trick I had 25 of each in a 3-hr flood-tide session at Tywyn a few years back, didn't even have time to stop & roll a ***!
