To Bleed or Not To Bleed?

[johnny roger]

i hear some fishos talking about 'slabbing' their fish while they are out camping or something. what is 'slabbing'?

JR>>slabbing is filleting and packing into slabs

Uripper ... pros do not have to gut or gill reef fish anymore as of 10 years ago they iki-jimi them to brain kill them immediately the flesh is better when the fish dies before stress of slowly dying apparently

Jeremy 87 said the best way to bleed and he is right by bursting the main veins infront or behind the pectoral fins each side before killing the fish...cutting next to the spine only does half the job

Ifish,
So im assuming then that slabbing is better for room in the ice box?

Yes, but by fisheries act we are not allowed to fillet any fish on the boat with a fillet of less than 45cm... so really you can't unfortunately, we have had this out with DPI before and they won't budge... amatuers also have to cut one of the pectoral fins off thier reefies and mackerel

in this discussion it may be useful to know (your enemy) - what some of us may consider an extremist view, but one that seems to be gaining popular traction

info about the killing method that may be of interest - http://www.fish.gov.au/manual/preparation.php#con

To kill finfish using iki jime
For maximum product quality and minimum stress to a finfish the iki jime (live killing) method can be used. This instant killing method reduces the accumulation of waste products in the flesh, minimises physical damage (including the loss of scales) caused by the animal’s sometimes violent body movements and keeps the finfish intact apart from a small hole in the head. For best effect the fish must be bled and chilled in an ice slurry immediately after it has been spiked.

In iki jime (pronounced “ick-ee jee-mee”) a spike or awl is inserted directly into the brain causing immediate brain death and the cessation of all motion. Iki jime also prolongs the process of rigor mortis—the natural stiffening of muscle tissues after death. Deterioration of flesh quality occurs mainly after rigor mortis, so delaying the onset and process of rigor mortis through “quick kill and chill” techniques produces a higher-quality product with a longer shelf life.

Some practice is required to perfect the iki jime technique. The position and angle of spike entry required differs between species and one example of each species may need to be cut lengthwise through the head to locate the position of the brain. When spiked correctly, a fish will exhibit a short but violent convulsion (due to the physical stimulation of the brain) before relaxing.

To use the iki jime technique:
Hold the fish firmly and insert a spike into the brain. This should be done as soon as possible after capture.
Bleed the fish by cutting through the top of the gills. Access the gills by lifting the gill cover.
Place the fish in an ice slurry. Use mostly freshwater and freshwater ice to produce a slurry with the consistency of wet concrete and a temperature between –1°C and +4°C for no more than 2 hours.
Remove fish from the ice slurry and process further or store as required.

more info on the topic http://www.recfish.com.au/hook_to_co...iki%20jimi.pdf

Iki Jimi is a Japanese term meaning quick kill. It is a method used to shut down the fish’s central nervous system promptly so that it prevents stress
and consequently improves the eating qualities of the catch.
There are two main iki jimi methods used, the most common being a spike
to the top of the head, the other being a spike through the gill cover up
towards the brain. The aim of both methods is to destroy the part of the
brain controlling the fish’s movement.
Spiking can significantly decrease spoilage if combined with rapid chilling.
Trained people should only carry out spiking as it requires skill and is only
effective if the fish is alive when administered. Iki Jimi is a humane way of

killing fish when conducted properly.

Is there a resource that shows the location of the brian in commonly caught fish??

Alternatively can somebody who practices iki jime point me in the direction of the brain in commonly caught species??

Dont bleed all species but I do SKIN all my eating fish, feel that is mor important than the bleeding on some species
cheers

Every fsh we bleed and de-fin and then drain into blood bin then into esky of ice
