Otway 4 and Robert G. Harcourt 1. Corresponding author: charlie. Received: 1 July Accepted: 15 September Opportunistic sightings of wobbegongs collected by recreational scuba-divers White Denim - Pretty Green Ep used to assess the distribution and relative abundance of wobbegongs in NSW. From July until Januarydives were undertaken by recreational divers and wobbegongs were reported.
Larger numbers of wobbegongs were sighted in northern compared to southern NSW. Spotted and ornate wobbegongs were sighted in similar numbers, but species composition was highly variable across locations. Only a few juvenile and newborn spotted wobbegongs were sighted, whereas small ornate wobbegongs were mostly sighted north of central NSW.
The latter were possibly the third, cryptic species, the dwarf ornate wobbegong. The paucity of sightings of small wobbegongs suggests that juveniles and newborns are inconspicuous to divers or that small wobbegongs are found in areas not visited by divers. Potential species and size segregation suggest that closing areas to fishing may enable populations to sustain current levels of commercial exploitation.
The cost-effectiveness of using recreational scuba-divers to opportunistically collect distribution and relative abundance data was apparent from this study.
However, the lack of spatial and temporal homogeneity in diving effort suggests that future studies should consider incorporating organized surveys and a facilitator, rather than using opportunistic records of sightings.
