2.6. Laboratory examination of S. asotus

All the field-collected S. asotus fish were killed and their intestine were dissected under a dissecting microscope by adding 0.75% saline solution ( Tang et al., 2008, 2009, 2012, 2013, 2014; Sulieman et al., 2014; Li et al., 2020b). Then the isolated intestinal contents were carefully examined for the presence of Exorchis sp. trematode under the stereo light microscope. The collected Exorchis sp. trematode were placed into small petri dishes containing 0.75% saline solution and counted under the microscope.
