QUEENSLAND, Australia — Growing concerns over bull shark populations in Queensland waterways have sparked calls from some anglers for changes to fishing regulations, amid claims that the predators are becoming more numerous and larger in size.
Bull sharks, known for their ability to thrive in both freshwater and saltwater environments, are commonly found in rivers, estuaries and coastal waters across Queensland. Their presence in heavily populated waterways has led to increased concern among recreational fishers and water users.
Some anglers believe bull shark numbers have risen significantly in recent years and are urging the Queensland Government to review existing management policies. Current regulations require fishers to release bull sharks measuring more than 1.5 metres and limit catches to one shark per person per day.
Advocates for regulatory changes argue that Queensland should consider adopting rules similar to those in New South Wales. Some have also proposed targeted population control measures in inland waterways where human activity is common.
However, marine scientists and conservation experts have warned against reducing shark populations without strong scientific evidence. Researchers say accurately estimating bull shark numbers remains difficult because the animals are highly mobile and can travel across large areas of both freshwater and marine environments.
Experts also note that bull sharks play a critical role as apex predators, helping maintain the balance of aquatic ecosystems. They caution that significant reductions in shark populations could disrupt food chains and negatively affect the health of waterways.
Bull sharks are among Australia’s most powerful shark species and can grow to more than three metres in length. Their reputation and frequent sightings in populated waterways have contributed to ongoing public concern about human-shark interactions.
The Queensland Government maintains that current fishing limits are designed to support sustainable management of shark populations while protecting marine ecosystems. Authorities have indicated that efforts are underway to improve population monitoring and gather more accurate data on bull shark numbers.
The debate highlights the challenge of balancing public safety concerns with conservation goals as Queensland continues to monitor one of its most well-known apex predators.
