This dataset describes the predicted occurrence of juvenile sharks around Northwest Australia, mapped over a 0.01 degree spatial grid. Juvenile sharks were mapped at two taxonomic levels: order by including all juvenile sharks sampled (all juveniles) and species by considering the three most abundant species sampled separately (grey reef (Carcharhinus amblyrhynchos), sandbar (Carcharhinus plumbeus), and whitetip reef (Triaenodon obesus) sharks). The data cover the period 2003-2013 and are derived from an analysis of count data derived from baited remote underwater videos deployed through various sampling programs. Further detail can be found in the following peer-reviewed publication: Oh, BZL, Sequeira, AMM, Meekan, MG, Ruppert, JLW and Meeuwig, JJ (2017), Predicting occurrence of juvenile shark habitat to improve conservation planning.

Estimates of blacklip abalone (Haliotis rubra) size at emergence were obtained from surveys of ten sites within the Mercury Passage on Tasmania's east coast. Size at emergence estimates were obtained from five populations inside the Maria Island Marine Reserve (MIMR) and at five adjacent sites where abalone harvesting occurs. The data sets includes abundance and size estimates of the main abalone predators, including the southern rock lobster (Jasus edwardsii), and competitors.
