“…One of the survival abilities of Bagridae comes from the morphological adaptation to the difference in size between males and females. This difference in size between males and females can explain the adaptive process of intrasexual selection, selecting partners, and reproductive methods [19] This is also because Bagridae is a Carnivorous europhagus feeder, which has broad and varied eating preferences, Bagridae can eat crabs, shrimp, small fish, polychaete, worms, algae, detritus zooplankton, and mud [20] another ability is that Bagridae has 4 pairs of barbels (Maxillarry barbel, Nassal barbel, Outer mandibular barbel, and Inner mandibular barbell) which functions as a location sensor and mechanoreceptor, thereby helping to adapt in muddy environments in deep waters [21], while the Oshphronemidae, can adapt to environmental stress, such as Trichopodus trichopterus which can survive in poor environmental conditions [22].…”
