Following Operation Sparrow 2, WG-FSA-17 noted the unprecedented availability of catch data from four IUU vessels including reported removals, video footage, and catch in gillnets recovered by an NGO vessel. As requested in WG-FSA-17 paragraph 2.16, this document provides an analysis of the spatio-temporal distributions of catch and effort by the Chang Bai, Nihewan and Read More

France and Japan revised a research plan to continue investigating the populations of Patagonian toothfish (D. eleginoides) in the Division 58.4.3a during the next fishing seasons from 2017/18 onwards, using standardized longline gear and established observation and tagging programs.

In this Division, research fishing has been conducted by France and Japan since 2012 in the Read More

The Antarctic toothfish (Dissotichus mawsoni) is an ecologically and commercially relevant fish. Lacks of information on the species come from the traditional fishery-based methodology to collect samples, which does not cover all the areas of its distribution. Here we want to promote an alternative non-extractive methodology to expand the routine collection of data in areas not Read More

Here we provide a progress update on the Antarctic toothfish genetic connectivity project (WS-DmPH-18/08). A total of 4237 tissue samples have been made available for this project from nine CCAMLR members with the vast majority of these collected during the 2017/18 season. Of the planned 550 sample sequences, DNA has been extracted so far from 473 samples with 304 samples containing Read More

Total numbers of Antarctic toothfish collected in the CCAMLR Conservation Zone were 600 fish which consist of 306 fish from the 58 area and 294 fish from the 88 area during February through March, 2016. Female ratios were found to be 0.49 in both areas, showing higher female occurrence with higher total length. The ratio of female among the 857 specimens of Antarctic toothfish collected from Read More

This paper outlines stock assessment related work that has been done in Subarea 48.6 since 2012 and some review of work that could offer lessons in how to advance stock assessment in Subarea 48.6 in 2019.

This paper represents the annual report of a multi-member longline survey on Patagonian toothfish (Dissostichus eleginoides) at Division 58.4.4b in the 2017/18 fishing season by France and Japan. One fishing cruise by French vessel (Ile Bourbon) took place in March 2018 and caught 1.6 tonne of D. eleginoides in 58.4.4b_2. The data set, C2 and Observer data, was Read More

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, Read More

Skates are frequently caught as by-catch during commercial longline fishing operations within CCAMLR subareas 48.3 and 48.4. Morphological evaluations of the by-catch in these subareas indicate that up to three species from the skate genus Amblyraja occur: A. georgiana, A. georgiana sp. anon and Amblyraja taaf. In this report, we present results from the Read More

Myctophids apparently represent the second largest (after krill) and most widely distributed biological resources in the Antarctic waters, which are the important food sources of top predators, particularly penguins. However, the information on age of those fishes are very limited and inconsistent. Moreover, the data on trophic relationship between penguins and myctophid fishes are scarce, so Read More
