Vertebrate Pest Control

The removal of non-toxic fox baits was monitored simultaneously using identification of tracks in sand plots and an inexpensive method of remote photography. During 1126 bait-nights carried out using both methods at sites in the central and northern tablelands of New South Wales, 106 baits were removed by a variety of target and non-target animals. Whereas the results of sand plots may be inaccurate or unreliable, particularly during poor weather conditions, remote photography provides results that are less open to misinterpretation.

Drifting Algae

The importance of drifting objects to small juvenile pelagic fish was investigated off the coast of New South Wales, Australia. Distance-related and temporal patterns in the distribution of clumps of drifting algae were investigated with 5000 m2 transects at five distances from shore (0.1, 0.5, 1, 5 and 10 km), two to three times per season for 2 years. Juvenile fish associated with drift algae were collected. Clumps of algae, predominantly Sargassum spp., were most abundant in spring, which coincided with the highest abundance of alga-associated post-flexion juvenile fish. Drift algae were also most abundant close to shore, probably due to the proximity to source and the dominant onshore winds. Fish were quickly attracted to drifting artificial objects (fish aggregation device; FADs), although the magnitude of attraction varied greatly among days. The relative abundance of small fish in open waters available to colonise FADs and differing weather conditions may explain much of this variability. More fish colonised FADs with an odour source than unscented control FADs, indicating small fish may use chemical cues to locate drifting structures. We conclude that juvenile fish actively seek drifting objects as pre-settlement habitat, which may reduce predation and enhance settlement opportunities.
