Preliminary study on reproduction in Champsocephalus gunnari from Subarea 48.3, Dr Eduardo Holmberg survey, February/March 1994
Abstract: A preliminary histological analysis on the ovarian development in Champsocephalus ... described for other species. A gonad maturation scale was elaborated and adapted to the macroscopic scale ... ovaries presented few atretic oocytes; in others a generalized regression was found.

Further development of pairwise tag detection performance index and its application to the stock assessment of toothfish in the Ross Sea fishery
sustainable yields. The assessment model assumes that all vessels have equal tag detection rates; as a ... -specific tag detection performance for the Ross Sea fishery using a case-control methodology which controls ... location (i.e. in the same fishing season and within a specified distance). The index was calculated as ... the matched control hauls. By iterating over all events for all vessels, we generated a relative index ...
