Sharks have been around for a long time, first evolving more than 400 million years ago! One would imagine them to be hardy, durable animals since they have outlived dinosaurs and survived several mass extinctions. This is not true, however, since sharks and rays are highly susceptible to stress, especially stresses related to handling and angling. One reason for this is that, unlike land animals, the organs of sharks and rays are not supported by internal structures but rather float around in a single soft cavity. This increases the risk of damage to their internal organs when the sharks and rays are dragged over hard surfaces or removed from the water. In addition, unlike terrestrial animals, and even other marine animals, sharks’ skeletons are made purely of cartilage and muscle, which means that, if pulled out of the water and handled poorly, the weight of the shark’s body could partially collapse onto its organs and in extreme cases, crush them.

1. Handling Guidelines for Anglers when Catching Endemic Catsharks and Shysharks
Although rarely targeted, catsharks and shysharks are commonly encountered by recreational anglers. Knowing how to handle and release them correctly helps minimise stress and injury, giving these unique and important endemic species the best chance of survival.
2. Handling Guidelines for Anglers when Catching Big Sharks
Large sharks are particularly susceptible to post-release mortality, especially when handling and release are prolonged or inappropriate. Following responsible catch-and-release practices helps minimise stress and injury, giving these vulnerable animals the best chance of survival after release.
3. Handling Guidelines for Anglers when Catching Rays
Rays are frequently encountered by recreational anglers, yet many are unintentionally injured through poor handling practices. Following responsible catch-and-release techniques helps minimise stress and injury, giving rays the best chance of survival after release.
