The study aimed to evaluate the current status of exploitation of Pangasius krempfi fingerlings in the estuaries of the Tien and Hau rivers. Primary data were collected by interviewing 75 households using stow nets and push nets from December 2024 to April 2025. The results showed that the fishermen operated for about four months each year, from August to November in the lunar calendar. The stow net caught about 5,200 fingerlings/net/year in the estuaries of the Hau river and 8,700 fingerlings/net/year in the estuaries of the Tien river, while the push net caught 27,800 fingerlings/ship/year and 27,500 fingerlings/ship/year, respectively. The push net in the Hau estuary was more financially efficient than that in the Tien estuary, with benefit and cost ratios of 0.54 and 0.17, respectively. Most of the fishermen reported a decline in fingerling yield and significant fluctuations in the number of exploiting households between the two areas. Some solutions for managing and protecting Pangasius krempfi fingerlings include continuing to raise fishermen's awareness of protecting aquatic resources, promoting and supporting livelihood conditions for fishermen in estuarine areas, and developing Pangasius krempfi fingerling production.
