I have fished the logan river for bull sharks many of times and we always catch them for the sport and take the odd one home for the table there are a lot of bull sharks in the logan through out the upper and lower reaches of the river they are mainly caught during the warmer months of the year and when you catch one there are normally more to follow but i always release them most of the time they are good fun to catch on light gear with a strong leader we have had better results with floating baits but since they are scavengers they will generally take any bait no matter where it is in the water
