Floodplain area is a very dynamic water system where the influence from terrestrial and river is high. This area is recognized as feeding, nursery and spawning ground of some fishes. Capture fisheries in this area is frequently occurred by using some of specific fishing gears which related to dynamic pattern of aquatic environment, such as water level, current, and physical-chemical aspects of water. The research was conducted in order to evaluate fish caught composition and fishing activity in floodplain swamp in middle part of Musi River by survey method. The result showed that 45 species of fish were caught and nine kinds of fishing gears were used by fishers. Gill nets were used in whole year, while seine were used only in the peak of dry season. Intra-annual variations of swamp water flow can modify the distribution and migratory pattern of fish species, with direct effects on fish catches.

The exploitation of Sepat siam (Trichopodus pectoralis, Regan 1910) that include native species of floodplain has been done on many years. One of the main fishing areas of this commodity is Patratani floodplain, Muara Enim Regency, South Sumatra. This commodity has been exploited over a long period and is expected to have a high pressure of fishing. The aim of this paper is to compare the utilization of sepat siam resources based on growth, mortality, and exploitation parameters between 2010 and 2017. Fish samples were collected monthly started from March to December in 2010, and April to December in 2017. The sample got from local fishers who fished around Patratani flood-plain waters. Sepat siam samples were measured on length (cm) and weight (gram) every month. The analysis has concluded based on the condition factor in both years. The growth parameters were analyzed by FiSATII software. The result of FiSAT II analysis drawn the growth factor was 0.86 in 2010, and have been growing slow to be 0.55 in 2017. The length infinitive in 2010 was around 21.5 cm and decreased to 18.3 in 2017. The other results showed that the exploitation level decreased from 0.61 in 2010 to 0.53 in 2017. The exploitation rate proved that the utilization of sepat siam was decreased but sill on overfishing conditions. The length size of sepat siam related to the optimum mesh size fishing gears was decreasing in 2017 compared to 2010. The age analysis shows for 21.5 cm of the infinitive length is achieved for 7 months in 2010, while 18.3 cm of that is reached for 10,5 months in 2017.Keywords:Exploitation levelFloodplainSepat siamABSTRAKKegiatan penangkapan Sepat siam (Trichopodus pectoralis, Regan 1910) yang merupakan spesies asli ikan rawa banjiran sudah dilakukan bertahun-tahun. Salah satu lokasi penangkapan komoditas ini adalah di rawa banjiran Patratani, Kabupaten Muara Enim, Provinsi Sumatra Selatan.Komoditas ini telah mengalami eksploitasi dalam jangka waktu yang lama dan diperkirakan mengalami tekanan penangkapan yang besar.Tulisan ini bertujuan untuk menampilkan eksploitasi atau pemanfaatan ikan sepat siam berdasarkan parameter pertumbuhan, mortalitas, dan eksploitasi pada tahun 2010 dan 2017.
