Protect spawning fish from capture
A site comparison study in 2012–2013 in a coastal bay in the Tasman Sea off Tasmania, Australia (McAllister et al. 2015) found that tagged school sharks Galeorhinus galeus less than one year old were detected more frequently inside than outside a shark spawning and nursery ground in which the taking of sharks was prohibited (shark refuge area), however slightly older immature sharks did not tend to stay within the refuge. These results were not statistically tested. On average, the 31 tagged sharks less than one year old were detected for 80% of time inside the closed refuge area. Of these, 19 sharks did not leave the refuge throughout the study, nine periodically left and returned between May and September 2012 and three left and were not detected again. Older immature sharks (between one and two years) spent on average 18% of time inside the refuge area and all eight individuals left the refuge in autumn and only one returned the following spring. Data were collected from 39 electronically tagged sharks. Shark movements were tracked by 58 receivers deployed in and around a shark refuge area (targeting or taking of sharks prohibited year round, year established not given) and 66 receivers in two areas further up the east coast of Tasmania. Data were recorded from January 2012 until May 2013.
