If you do choose to string your fish to your float be sure to atleast "brain" your fish. This is a method we use in hawaii to keep from attracting the "tax collectors." Its very easy to do (with most species) and has minimal amounts of blood... if done right.

Insert your dive knife into the back of the head just above the eyes (usually along a 45 degree angle from the eye to the tail) Give your knife a quick turn and twist and you should feel the fish give a last "shudder." This is the part of spearing I hate but it is crucial. If you want to avoid the untimely visit from the tax collector kill your fish imediately. The vibrations given off by a dying fish are a dinner bell for hungry sharks, even more so than a little blood in the water.

Another easy way to brain a fish is to insert the knife into the gills and push it into the head towards the eyes.

These are good methods but like I said it works with "most" species of fish. You will find that sometimes, with certain fish, it seems impossible to kill them. It will take a little experience to get it right. The ideal way would be a kayak, or an innertube, but the downfall to these is that you may venture far away from your kayak, and with an innertube they are a bitch to tow around.

Good luck!
