Mekong Delta Floods Bring Rare Fish Back, Highlighting Resource Management Challenges

Recent heavy rains and floods from the Mekong River's upper reaches have inundated vast swathes of farmland in the Vĩnh Tế, Thới Sơn, and Tịnh Biên communes of An Giang province, as well as Nhơn Hội xã. Notably, many residents report the reappearance of rare fish species, such as grouper, catfish, threadfin, and sea bass, which were thought to be dwindling. This is a welcome sign for the Mekong Delta's "flood season" ecosystem. According to Dr. Nguyễn Văn An, Deputy Director in charge of the Center for Agricultural and Food Product Production at Kiên Giang University, the upstream areas of Đồng Tháp and An Giang provinces used to teem with freshwater fish and shrimp during the flood season, including various carp species, snakeheads, catfish, and prawns. However, in recent years, the catches of these species have significantly declined. This is partly attributed to a low level of resource management awareness among some residents, who engage in "destructive fishing" practices. This has damaged the fish's breeding ecosystem, slowing the recovery of natural fish populations. Furthermore, the fish caught are no longer as large as they once were. To manage these resources, many localities in the upstream areas of An Giang and Đồng Tháp provinces have implemented patrol and control plans, urging residents to refrain from using prohibited fishing gear and nets with mesh sizes exceeding regulations. Concurrently, efforts are underway to promote a shift in mindset from "catching fish when available" to "protecting breeding populations." Experts emphasize the need for "season and size-based management" for species like carp, rather than focusing solely on immediate catch volumes. Past resource management regulations stipulated that carp could only be fished after August 31st and must reach a minimum length of 50mm. Therefore, the provinces along the Tiền and Hậu rivers now need to establish unified, inter-provincial management methods, clearly announcing fishing seasons, permissible catch sizes, and approved fishing gear. Increased inspections and strict penalties for destructive fishing practices are also crucial. The flood season provides a dual benefit to the residents of the Mekong Delta's upstream regions: it brings fertile silt for rice cultivation and offers abundant aquatic resources. Consequently, residents' adherence to not using electric shock devices or prohibited fishing methods is essential for protecting their own livelihoods and the economic value of the delta.
