“…The spawning season of O. interrupta was in between March through May which is similar to that of O. platycephala, belongs to the same family (Iwata et al, 1988) (Choi & Jin, 1977;Han et al, 1998;Moon et al, 2005;Choi et al, 2008;Seo et al, 2006).…”

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.

“…In the study, we found that eggs of O. interrupta were demersal eggs attaching on the bottom of rocks that forms a layer, these properties are somewhat different compared to other fishes L. mediadiposalis and L. andersoni which lay non sticky egg clusters (Seo et al, 2006;Choi et al, 2008).…”

“…Compared to other species in the same family Bagridae, the egg size was larger than 1.70±0.08 mm ( Kang & Lee, 1996 ) or 2.04±0.07 mm ( Han et al, 2001 ) for P. fulvidraco , and 1.99 mm for Pseudobagrus brevicorpus ( Kang et al, 2007 ), and smaller than 2.59± 0.08 mm for P. koreanus ( Kang, 1998 ). It was smaller than 3.27 mm for Liobagrus mediadiposalis and 3.30 mm for L. obesus in the same order Siluriformes ( Choi et al, 2008 ; Seo et al, 2006 ).…”

“…Research on the early life history of fish provide various data about fish species including the morphological and physiological characteristics of eggs and the unique traits and developmental characteristics of the species observed through the processes of embryonic development and early growth, and therefore, we can get various types of taxonomic, embryological, and ecological knowledge from such studies ( Song & Choi, 2000 ; Choi et al, 2008 ).…”

“…This suggests that incubation period is somewhat varied according to water temperature. It took 53 hours at water temperature 25.0℃ ( Kang & Lee, 1996 ) and 56 hours at 24.9℃ ( Han et al 2001 ) for P. fulvidraco , 72 hours at 21.0~23.0℃ for P. koreanus ( Kang, 1998 ), 50 hours at 24.0℃ for Pseudobagrus brevicorpus ( Kang et al, 2007 ), 189 hours 20 minutes at 22.5℃ for Liobagrus mediadiposalis ( Choi et al, 2008 ), and 225 hours 15 minutes at 22.8℃ for L. obesus . In the fishes of order Siluriformes , incubation tended to be shorter at high water temperature, and Leiocassis ussuriensis took a longer time to hatch than P. fulvidraco at the same water temperature ( Kang & Lee, 1996 ).…”

This study was examined the ovogenesis of Ussurian bullhead, Leiocassis ussuriensis and the morphological development of its larvae and juveniles and to use the results as basic information for the preservation of species and resource enhancement. For artificial egg collection, human chorionic gonadotropin (HCG) was injected at a rate of 10 IU per gram of fish weight. During breeding period, water temperature maintained at 24.5~26.5°C (mean 25.0±0.05°C). The process of ovogenesis reached the two-cell stage in 50 minutes after fertilization. In 73 hours of fertilization the movement of the embryoid body became active state and the larvae began to hatch from the tail through the oolemma. Length of prelarvae were 6.33~6.50 mm long (mean 6.40±0.06 mm) just after hatching having yolk with their mouth not opened. After thirty eight days of hatching, juveniles were 30.6∼32.5 mm long (mean 31.5±0.65 mm). The color was dark yellowish brown throughout the entire body, and the number of caudal fin rays developed to thirty six perfectly.

This study was conducted to investigate egg development and larvae morphological development of catfish and to provide basic data to clarify the genetic relationship with Siluriformes fish. The mother fish that was used in this study was caught in the stream of Nakdong River in Uiseong-gun, Gyeongbuk. The temperature range of the breeding was 23.0-25.0℃ (mean 24.0±1.0℃) and egg size was 1.62-1.70 mm (mean 1.66±0.05, n=30). Eggs of catfish began hatching at 54 hours and 40 minutes after fertilization. Immediately after hatching, the total length of larvae was 3.60-3.65 mm (mean 3.62±0.03, n=5) and had an egg yolk without swimming ability. On the third day after hatching, the larvae at the medium stage was 8.00-8.65 mm (mean 8.32±0.45) in total length, and two pairs of whiskers formed around the mouth were elongated. On the 12th day after hatching, the larvae at the juvenile stage was 16.5-17.0 mm (mean 16.7±0.35) in total length, and the stem of each fin was in the range, and the juvenile at this period was morphologically similar to the mother fish.
