Results from the current ‘proof of concept’ study indicate that near infrared (NIR) spectra collected from fish otoliths have potential to estimate the age of Barramundi (Lates calcarifer) and Snapper (Pagrus auratus), with performance varying between species and locality of capture. A...

A 12-month creel survey of recreational boat-based fishing in Shark Bay, Western Australia was conducted between May 2001 and April 2002 to estimate the catch of pink snapper. During the survey 431 boat crews were interviewed at public boat ramps of which 414 had been fishing.
The information...

Through two national workshops, Indigenous community and agency representatives and researchers discussed issues around collecting, sharing and ownership of Indigenous fishing data. Challenges and opportunities were shared from all perspectives and expertise, knowledge and information came together...

There are increasing demands for Australian fisheries management agencies to demonstrate that fisheries under their jurisdiction are being managed in accordance with the principles of ecologically sustainable development (ESD). The decision-making processes of the ESD management framework...
Snapper has been fished since the early development of the colony around Sydney Harbour in the late 18th century, but it was the arrival of steam power in the 1860’s that enabled fishers to start regularly targeting the abundant schools of snapper occurring in the deep-water fishing grounds...

The investment in this project has resulted in a substantially more extensive set of age composition data than would have otherwise been possible. This in turn has underpinned stock assessment modeling that has provided the basis for determining that the commercial fishery for snapper in Shark...

Many strategies have evolved among fishes to maximise spawning success. One of the most striking of these is aggregation spawning, in which individuals group together, often at predictable times and locations in order to reproduce (cf. a school, which refers to a group of non-spawning fish)....
