“…Tire track eel (Mastacembelusfavus) is a native fish species that live mainly in freshwater but is also found in brackish water with low salinity (Pethiyagoda, 1991;Sokheng et al, 1999;Mongabay, 2020). In the wild, they are very widely distributed, at different habitats, from upstream to downstream, swampy areas, estuaries, or in riverbeds with fine or coarse sandy bottoms and places with thick vegetation (Ahmad et al, 2018;Jamaluddin et al, 2019;Jamaluddin et al, 2021). This is a hidden species, so they usually concentrate mainly on the bottom of flowing water bodies (canals, lakes) in the summer months or in flooded areas in the rainy season.…”

Tire track eel (Mastacembelus favus) is an economically important freshwater fish in the Mekong Delta. However, there is a lack of academic information about the current farming status, feed, and feeding related to this species in the region. Therefore, a field survey of small scale farming of tire track eel was conducted in An Giang, Dong Thap, Hau Giang and Kien Giang provinces of Vietnam. The objective of the survey was to determine the current farming practices information on households, especially the feed and feeding status of tire track eel in order to improve and develop a suitable feed for this fish in the future. The results showed that most of the small-scale farmers cultured fish in earthen ponds with or without plastic liners. Tire track eels were fed with feeds of other species and typically fed 3 - 5 times/d during the fingerling stage, and twice per day during the grow-out period. In terms of feed ingredients, crude protein contents in the feeds were 39.5 - 45.5% while crude lipid contents were 7.7 - 12.7%. Feed conversion ratios of tire track eels were 2 - 5. The farming periods of fish were 11.8 - 14 months when the fish reached the harvesting sizes of 318.2 - 421.4 g/fish, with the survival rates of 40 - 80%. It took 2.5 months to cultivate the fingerling stage (around 3 g/fish) from the fry with the survival rate of 55.7%. It was reported that this species was raised with a simple technique and got less illness compared to other fish species. However, the main reason of fish deaths during farming period related to management factors such as poor water quality due to decomposition of uneaten feed in water or lacks of dissolved oxygen due to high stocking density or power supply failures.
