Blue grenadier has the highest current TAC among SEF species and has two separate fisheries that target primarily either sub-adult fish year-round or mature adults in winter spawning aggregations. The sustainability of the fishery would be greatly enhanced with regular (sustained) monitoring of...
During the early 2000s, stock assessments highlighted considerable issues with the status of South Australia’s stocks of Southern Garfish (Hyporhamphus melanochir). This led to significant management changes that were implemented in 2005, which included the introduction of new...
Close kin mark recapture (CKMR) provides an estimate of absolute abundance that is independent of fishing behaviour. We present a first CKMR estimate of abundance for School Shark and discuss the management implications of our findings.
We found 65 half sibling pairs (HSPs), 3...
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)....
