Egg Development and Early Life History of Korean Endemic Species Korean Spotted Sleeper, Odontobutis interrupta (Pisces: Odontobutidae)

Abstract

The egg development and early life history of Korean spotted sleeper, Odontobutis interrupta which is Korean endemic species from Sora-choen was investigated. The Korean spotted sleeper were caught at Sora-myeon, Yeosu-si, Jeollanamdo, from Korea at May in 2014. The fertilized eggs were 4.23 ± 0.05 mm in long diameter and had oil globules. Hatching time of the embryo began about 442 hr 14 min after fertilization under water temperature of 19.5 o C. The newly hatched larvae were 4.27 ± 0.35 mm in total length and their anus were not yet opened. 3 days after hatching postlarvae was measured 6.20 ± 0.11 mm in total length. 10 days after hatching postlarvae was measured 6.69 ± 0.14 mm in total length.

“…Studies on the early life history of fish have been widely utilized and acknowledged as important data not only to understand the biological features of fish species, but also to investigate their breeding ecology and conservation of endangered species (Blaxter, 1974; Mihelakakis, Yoshimatsu, & Tsolkas, 2001; Moore, 1982; Park et al, 2014; Takeshita, Onikura, Matsui, & Kimura, 1997; Yokouchi et al, 2016). Furthermore, information on embryonic and larval development of fish is a fundamental key which enables a closer approach to their biology and taxonomy (Celik, Celik, Cirik, Gurkan, & Hayretdag, 2012).…”
