The ecology of the tiger shark

the ecology of the tiger shark Neil hammerschlag, a marine ecologist at the university of miami who studies tiger sharks in the western atlantic, says sea turtles there don’t seem to alter their behavior in response to tiger sharks the way the turtles in shark bay do, and that might be because atlantic tiger shark populations are already significantly compromised.

In shark bay, we have worked not only on sharks, but on their prey — including dolphins, sea turtles and sea cows — as well as the wider ecosystem our findings demonstrate that tiger sharks are critical to the shark bay ecosystem but not in the way you might think. Diet and trophic ecology of the tiger shark (galeocerdo cuvier) from south african waters. Knowledge of the diet and trophic ecology of apex predators is key for the implementation of effective ecosystem as well as species-based management initiatives using a combination of stomach content data and stable isotope analysis (δ15n and δ13c) the current study provides information on size-based and sex-specific variations in diet, trophic position (tp) and foraging habitat of tiger.

The tiger shark (galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus galeocerdo it is a large macropredator, capable of attaining a length over 5 m (16 ft 5 in) populations are found in many tropical and temperate waters, especially around central pacific islands. Catch rate data from hawaii indicated that shark control programmes did reduce tiger shark abundance (wetherbee et al 1994) these data suggest that at best the use of shark control programmes to reduce population levels of tiger sharks may be of only limited value.

The diet and trophic ecology of large sharks can be assessed using a range of techniques each technique, however, has its own limitations and biases, which need to be considered when designing studies and interpreting results.

In shark bay, we have worked not only on sharks, but on their prey — including dolphins, sea turtles and sea cows — as well as the wider ecosystem our findings demonstrate that tiger sharks are critical to the shark bay ecosystem. Some shark scientists believe that this intimidation factor may actually have more of an impact on the ecosystem than what sharks eat for example, scientists in hawaii found that tiger sharks had a positive impact on the health of sea grass beds turtles, which are the tiger sharks’ prey, graze on sea grass. Tiger sharks are caught in numerous fisheries world wide, both as target species and bycatch products utilised from tiger sharks include flesh, fins, skin, liver oil and cartilage although not considered of high quality, the mercury content of this shark's flesh is lower than other large carcharhinid species (simpfendorfer pers data.

The ecology of the tiger shark

Through access to long term data on tiger shark stomach contents (1983 to 2014) combined with multiple tissues sampled from recent captures (2006 to 2014), this paper provides a detailed investigation of the diet and trophic ecology of g cuvier off kwazulu-natal (kzn). For example, scientists in hawaii found that tiger sharks had a positive impact on the health of sea grass beds turtles, which are the tiger sharks’ prey, graze on sea grass in the absence of tiger sharks, the turtles spent all of their time grazing on the best quality, most nutritious sea grass, and these habitats were soon destroyed.

  • And diet by size class the order in which the stomachs were analysed was randomised 500 diet and trophic ecology of the tiger shark.

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. Through access to long term data on tiger shark stomach contents (1983 to 2014) combined with multiple tissues sampled from recent captures (2006 to 2014), this paper provides a detailed investigation of the diet and trophic ecology of g cuvier off kwazulu-natal (kzn), south africa. Tiger sharks with surgically implanted ultrasonic transmitters all swam more than 16 km within one day of their release, and it took between two weeks and 9 months for them to revisit the area where they were released feeding behavior (ecology) tiger sharks likely have the widest variety in their diet out of all shark species.
