1. Description of the tagging process and the development of a cradle for optimum landing and measuring of large fish followed by the Spanish F/V Tronio

   Abstract:  During the 2017/18 season the Spanish F/V Tronio fished in Statistical Subarea 88.1 and Division 58.4.1 where the latter area required a tag rate of five fish per ton greenweight caught and also where the overall size of the fish exceeds 115cm. The tagging station on the FV Tronio is on
