This study was carried out to obtain the biological studies on aquaculture fundamental data for the resources annexation of Miichthys miiuy in terms of the characteristics of the spawning and effect of salinity. The adults spawners in 5 years were TL $72.3sim89.6;cm$, BW $3,736sim8,818;g$ in female (n=39), TL $47.1sim81.2;cm$, BW $716.6sim6,853;g$ in male (n=24). The adults size which were suitable for a stable egg collection were $97.9sim110.2;cm$ in total length, $9,657sim13,200;g$ in body weight. Each egg contained $1sim5$ oil globules. Also, the highest hatching rate was 96.7% at the one having an oil globules. The highest hatching rate was 87.0% at 30.0 ppt. The fastest time required from fertilization to hatching was 17 hours 24 minutes at 28.0 ppt. |
