Dusky shark remains in Busan canal as authorities monitor its condition
The story at a glance
A female dusky shark, named Bukangi, has remained in a canal at Busan’s North Port Waterfront Park since 18 September. South Korea’s National Institute of Fisheries Science (NIFS) identified her as a dusky shark about three metres long.23
Two attempts to guide the shark to open water failed. Authorities were monitoring her condition, and reporting as of 16 October said they planned to continue monitoring before deciding whether to try another rescue.13
The story in brief
What you need to know
- The shark’s presence has attracted substantial public attention: Mongabay reported nearly 1.4 million visits to see her. The reports describe concern for her welfare alongside the public interest.1
- The canal’s confinement raises welfare concerns. Busan’s initial assessment found that the shark was swimming and breathing normally, but the city said prolonged confinement could restrict feeding and movement and weaken her.4
- There is wider regional context of changing marine conditions. The Korea Meteorological Administration found that average sea-surface temperature around the Korean Peninsula in 2016–2025 was 0.7°C above the 1991–2020 average.6
- NIFS recorded 46 shark sightings in the East Sea by mid-2026, compared with 12 in 2025. It cited rising water temperatures and the expanding distribution of warm-water fish as possible factors in the regional increase.5
- Those regional patterns do not explain why Bukangi entered this canal. The reporting says a single sighting cannot establish climate causation, and identifies prey distribution, currents, tides and the waterway’s configuration as factors requiring investigation.15
Conservation context
Why this matters
The case highlights the challenge of responding to a large animal in an urban waterway while limiting stress and protecting its welfare. It also shows why regional temperature and sighting trends should not be treated as proof of the cause of one animal’s movements.1456
The developing story
What happens next
As of 16 October, authorities planned to continue monitoring Bukangi before deciding whether to attempt another rescue. The available reporting does not give a later decision or outcome.1
Established evidence
What we know
- NIFS identified Bukangi by the ridge between her dorsal fins, which it described as a distinguishing feature. It identified her as female and estimated her length at about three metres.2
- The first reported attempt, on 29 September, used boats and water pumps; a second attempt, using a net, took place on 2 October. Neither succeeded in guiding the shark out.3
- NIFS’s temperature analysis used observations from 17 buoy sites around the Korean Peninsula, each with at least 10 years of data.6
Open questions
What we don't know
- The reporting does not establish what combination of prey, currents, tides or canal conditions led Bukangi into the waterway.1
- Although checks reported no major health problem as of 6 October, the available sources do not give a later assessment or resolve concerns about feeding and longer-term welfare.34
- It remains unclear whether authorities will make another attempt to guide the shark to open water, or how long monitoring will continue.1
- The reporting does not show whether longer-term monitoring can establish that changing sea conditions are shifting shark distributions in Korean waters.156
