“…Alternatively, these pups could have been delivered by a pregnant vagrant female. It has been reported that tiger sharks undertake trips of thousands of kilometres (8,000 km in 99 days (Heithaus et al, 2007), or 1,800 km in 48 days (Holmes et al, 2014) and gestation periods of 12-16 months have been estimated (Clark & von Schmidt, 1965). Therefore it is possible that mating could have happened outside the Mediterranean.…”

One male and one female specimen of tiger shark, Galeocerdo cuvier (Péron & Lesueur, 1822), were accidentally caught by a drifting longline for swordfish in the south Mediterranean (Libyan waters). This finding confirms beyond any doubt that the tiger shark may be encountered in the waters of the Mediterranean Sea. Although records of this species has previously been reported, the information is partial or dubious, due to the lack of a description of the individuals found or the uncertain provenance of preserved material. Our finding confirms the record of this species in the southern part of the Mediterranean basin. Images, as well as morphometrics and information on stomach contents are given. Based on the size of the individuals, it is considered that the two specimens were born recently, presumably inside the Mediterranean Sea and likely close to the area where the individuals were found.

“…There was evidence that Hawaiian sharks showed a similar pattern to Australian sharks, with Hawaiian sharks being more prevalent in coastal waters when temperatures were at their coolest ( Figure 3b). Furthermore, there is evidence that at least some tiger sharks choose to encounter SSTs of 22°C year-round: two tiger sharks tagged with satellite transmitters off the east coast of Australia (data originally presented in Holmes et al, 2014) were recorded migrating seasonally over approximately 12°of latitude, continuously exposing themselves to SSTs close to 22°C in the process (Figure 4.

Combining abundance and performance data reveals how temperature regulates coastal occurrences and activity of a roaming apex predator

The redistribution of species has emerged as one of the most pervasive impacts of anthropogenic climate warming, and presents many societal challenges. Understanding how temperature regulates species distributions is particularly important for mobile marine fauna such as sharks given their seemingly rapid responses to warming, and the socio-political implications of human encounters with some dangerous species. The predictability of species distributions can potentially be improved by accounting for temperature's influence on performance, an elusive relationship for most large animals. We combined multi-decadal catch data and bio-logging to show that coastal abundance and swimming performance of tiger sharks Galeocerdo cuvier are both highest at ~22°C, suggesting thermal constraints on performance may regulate this species' distribution. Tiger sharks are responsible for a large proportion of shark bites on humans, and a focus of controversial control measures in several countries. The combination of distribution and performance data moves towards a mechanistic understanding of tiger shark's thermal niche, and delivers a simple yet powerful indicator for predicting the location and timing of their occurrences throughout coastlines. For example, tiger sharks are mostly caught at Australia's popular New South Wales beaches (i.e. near Sydney) in the warmest months, but our data suggest similar abundances will occur in winter and summer if annual sea surface temperatures increase by a further 1-2°C.

“…Regional differences in prey availability may also affect growth rates (Wirsing et al, 2006), highlighting the need for regional assessments to be completed. Indeed the movement capabilities of G. cuvier, particularly across the southwest Pacific, are seasonal and wide ranging, and encompass the use of both tropical and warm temperate waters, thus encountering a wide variety of locally-abundant prey species throughout their distribution (Holmes et al, 2014;Werry et al, 2014). The aim of the present study was to examine the age and growth of G. cuvier off the east coast of Australia using vertebral band-pair 42 counts from pre-and post-natal individuals.…”

“…cuvier maintain variable home ranges, with movements extending across the broader Indo-West Pacific into both tropical and seasonally warm temperate waters (Holmes et al, 2014). Throughout the region G. cuvier is targeted primarily by recreational shark game fishers and by shark control programs, and is also taken by commercial fishing operations (Pepperell, 1992;Holmes et al, 2012).…”

The tiger shark (Galeocerdo cuvier) (Péron and Lesueur 1822) is the largest of the carcharhinids, with a circumglobal distribution in both tropical and warm temperate coastal and pelagic waters. In the western Pacific, G. cuvier movements are wide-ranging, encompassing the east coast of Australia and south Pacific Islands.Throughout the region, G. cuvier is exposed to a range of commercial, recreational, artisanal and illegal foreign fishery impacts, as both a target and by-product species.Listed as 'near threatened' on the International Union for Conservation of Nature (IUCN) Red List, suitable long term species-specific catch, catch rate and biological data are seldom available for large shark species like G. cuvier, particularly where historical commercial fishery logbook reporting has been poor.Shark control programs targeting large sharks along Australia's east coast have been in operation for over 60 years, using relatively standardised fishing gear in nearshore waters all year round, with historical catch and effort data recorded by shark contractors. Historical catch, catch rate and biological data collected through the Queensland Shark Control Program (QSCP) since 1993 were investigated, which revealed significant declines (p < 0.05) in catch rates of G. cuvier at some tropical and all sub-tropical locations along the Queensland coast. Significant temporal declines in the average size of G. cuvier also occurred at four of the nine locations analysed (p < 0.05), which could be indicative of fishing reducing abundance in these areas. Interannual variability in catches at each location was considerable and warranted careful interpretation with respect to estimating population abundance from these data.Investigation into the spatial and temporal movements of tiger sharks, and how their abundances fluctuate in relation to environmental influences, provided a basis for determining the factors driving this variability.Tiger shark movements were recorded using PAT Mk-10 and SPOT5 electronic tags to investigate G. cuvier spatial dynamics, site fidelity and habitat use off the east coast of Australia. Of the 18 tags deployed, 15 recorded information on depth and/or temperature, and horizontal movements, with tracking times ranging between four and 408 days. Horizontal movements were characterised by combinations of resident and transient behaviour that coincided with seasonal changes in water temperature, with summer migrations from sub-tropical Queensland waters to the southern temperate iii waters of New South Wales (NSW) to exploit the seasonally warm and prey abundant waters. While the majority of movement activity was focused around the continental slope, large-scale migration was evident with one individual moving from offshore Sydney, Australia, to New Caledonia (≈ 1800 km) in 48 days. Periods of tiger shark residency outside of Australia's fisheries management zones highlighted the potential vulnerability of the species to unregulated fisheries, and the importance of crossjurisdictional arrangemen...
