People claim that Barracouta have worms, it might be true but I suspect they would do humans no harm. Especially after being cooked. I have tried eating a small barracouta before and can not remember the taste. They are a great fighting fish and fun on a light gear.
The wakamarina does not hold enough fish to bother with ‘blind fishing’. It would be a option on a few of the larger rivers with high fish populations. The lower Pelorus would be a option in high flows.
