Thanks for the reply jewgaffer. It's pure gold.
A few questions:
1. about the 45 degrees. once ive located the spot (1cm above the eye annd 1cm backwards towards the body) to spike, do i push down 45 degrees towards the body of the fish? which direction?
2. how do i bleed the fish properly? what are the steps? im a complete newbie!
3. why do you keep the fish out of an ice slurry? wouldnt that be good since it'll freeze the flesh real good? how about putting the fish in a bag and then in the slurry?
4. why keep the guts in until u get home?
