Preliminary results of stock estimation for D. mawsoni using CASAL in the research block 48.6_2
Abstract: A preliminal CASAL model was constructed for D. mawsoni at the research block 48.6_2 ... . The model assumes that single sex and age structured model without considering IUU. Tag release data ... during 2012–2017 was used. Catch data during 2006–2017 was used as fishery data. In the MPD, age and ... CPUE fit well. On the otherhands, fit of tag release are relatively low level, especiall in 2016. The ...
