Characterization of the different behaviours exhibited by juvenile grey mullet (Mugil cephalus) under rearing conditions

“…Similarly, Ibarra-Zatarain & Duncan (2015) reported that gilthead seabream tended to swim slowly either alone or in small groups around the tank during early morning (08:30 hours). Likewise, Park et al . (2018) reported the same resting behaviour in the Korean endemic cobitid ( Iksookimia hugowolfeldi ) in the wild.…”

“…Similar results have been found by Anders et al . (2017) and Park et al . (2018) in cod ( Gadus morhua ) and the Korean endemic cobitid, suggesting that this preference to feed is associated with their natural feeding habits.…”

“…On the other hand, rubbing behaviour has been related to the lifestyle and feeding strategy of this fish species (Almada et al ., 1999), and similar observation was reported in the korean endemic cobitid. This fish species showed a zig zag swimming behaviour which was associated with their habitat and feeding behaviour (Park et al ., 2018). Additionally, Islam et al .…”

Comparative Morphology and Morphometry of the Olfactory Organ of the Six Korean Spined Loaches, Genus Iksookimia, as a New Taxonomic Key

“…The tubular nostril typically appears in bottom-dwelling teleosts is a functional boundary layer between inflow of chemical odors to the olfactory organ (Belanger, 2003;Sarkar et al, 2014;Kim and Park, 2020). Such an olfactory entrance may be related to the benthic habitat of Korean spined loaches, which spends their lifetime on the river bottom (Kim and Park, 2002;Park et al, 2018).…”

“…koreensis, Kim (1975); Iksookimia pumila, Kim and Lee (1987); Iksookimia pacifica, Kim et al (1999); Iksookimia longicorpus, Kim et al (1976); Iksookimia hugowolfeldi, Nalbant (1993); Iksookimia yongdokensis, Kim and Park (1997), based on habitat preference and morphology (Ko, 2015;Park et al, 2016;Ko et al, 2020).…”
