Article Synopsis
- The study examines the population structure of Bull Sharks globally, revealing reproductive isolation among different ocean basins and distinct island populations, such as those in Japan and Fiji.
- Through advanced DNA analysis, researchers found that Bull Sharks use shallow coastal waters for dispersal, while geographical barriers limit gene flow, which impacts their conservation.
- The findings highlight the vulnerability of local Bull Shark populations to overfishing, particularly among females that return to specific breeding areas, emphasizing the need for targeted management strategies to prevent local declines.
Knowledge of population structure, connectivity, and effective population size remains limited for many marine apex predators, including the bull shark . This large-bodied coastal shark is distributed worldwide in warm temperate and tropical waters, and uses estuaries and rivers as nurseries. As an apex predator, the bull shark likely plays a vital ecological role within marine food webs, but is at risk due to inshore habitat degradation and various fishing pressures.

Whilst large shark species are often difficult to study with direct methods, improved knowledge is needed for both population management and conservation, especially for species vulnerable to anthropogenic and climatic impacts. The tiger shark, , is an apex predator known to play important direct and indirect roles in tropical and subtropical marine ecosystems.
