Proposal for a CCAMLR sponsored research survey to monitor abundance of pre-recruit Antarctic toothfish in the southern Ross Sea
Abstract: The exploratory fishery for Dissostichus spp. has now been operating for 14 years ... in Subarea 88.1 and for nine years in Subarea 88.2. Associated research has led to an assessment ... operations, different vessels catch different length classes in different locations and in different years ... methodologies. Further, we propose that the first survey be a pilot, with two main objectives ...
