<![CDATA[Cantrang is a type of fishing gear considered to have low selectivity for catch species and size but high productivity. Its operation involves scraping the seabed, which may negatively affect aquatic ecosystems, including coral reefs. This study aimed to analyze the composition of cantrang catches landed at Brondong Fish Auction Place (TPI) and examine the construction characteristics of the cantrang fishing gear operated at the site. The research was conducted at TPI Brondong from December 2023 to January 2024 using direct observation and interviews with local fishermen. The Shannon–Wiener diversity index was 2.46, indicating a moderate level of species diversity, while the catch dominance index was 0.89, indicating high dominance by certain species. These findings suggest that the cantrang fishing gear has low selectivity and is not environmentally friendly. The operated cantrang had a wing mesh size of 7.5 cm made of polyethylene, while the net body had mesh sizes of 6.8 cm, 4.4 cm, and 2.7 cm toward the codend. The codend had mesh sizes of approximately 1.5 cm and 1.1 cm. The upper and lower ropes were each 50 m long, while the selambar rope was 1,000 m long. The findings provide information on catch composition and gear construction as a basis for evaluating the selectivity and environmental sustainability of cantrang fishing operations.]]>
