Making your own!
Many popular recreational fish species, such as Mulloway, Pearl Perch and Snapper, are often caught from water deeper than 10 metres. Fish hooked at such depths can display a range of injuries due to changes in water pressure as they are brought to the surface. These injuries are known as barotrauma and can affect the survival of released fish.
