Sharks are marine animals that play an important role in marine ecosystems especially as the main predator, thus controlling the dynamics of populations of other organisms at lower trophic levels. Sharks are often caught as a byproduct of capture fisheries in Indonesia, making Indonesia one of the five largest shark contributing countries in the world according to the FAO. A study of shark populations needs to be done to evaluate its stock in nature. The Mayangan Coastal Fishery Port, Probolinggo is one of the largest fishing ports in East Java with the majority of fishing gear used being cantrang. This study will discuss the shark bycatch volume in fishing activities using cantrang fishing gear at PPP Mayangan, Probolinggo. The use of cantrang fishing gear in Mayangan Port Probolinggo has produced around 6242.9 kg of shark production each year for the past 10 years. The highest production was found in 2011 which reached 10980 kg while the lowest was in 2019 with a total production of 412 kg. The pattern of the development of shark catches at PPP Mayangan Probolinggo showed a decrease in the number of catches, indicating the enforcement of law regarding cantrang usage has been well adapted.
