Workshop on Assessment Methods for Icefish CCAMLR.
Species icefish Area all Season all Gear trawl 1.
The Commission currently manages toothfish, icefish and krill fisheries.
However, icefish feed predominantly on krill and therefore must, at some time, have an.
Fishery plans are available for all krill, icefish and toothfish fisheries in the Convention Area.
In addition, workshop participants compiled a bibliography on Champsocephalus gunnari(mackerel icefish) Attachment E.
The random forest analysis classified krill, icefish and mixed aggregations with an estimated accuracy of 95.
These regulations are usually specificto a fishing season, and currently apply to toothfish, icefish and krill fisheries.
Dr Kasatkina noted that icefish assessment should be prepared by combining data from bottom trawl survey and acoustic survey respectively.
The amount of offal would be expected to be relatively small as the icefish catch was frozen whole.
There were six reported in the icefish fishery in Subarea 48.3 and two in the icefish and toothfish trawl fisheries in Division 58.5.2.
An example is marbled rockcod in all subareas where it was found and icefish in Subareas 48.1 and 48.2.
Otoliths TOT: not required Icefish: 5 otolith pairs of combined icefish species every set Note: maximum 200 fish per species per vessel.
A total of 19 species were recorded from 1 173 net hauls, including icefish(Champsocephalus gunnari) and myctophid species.
SG-ASAM noted that considerable uncertainty exists around the estimation of the relationship between TS andfish length for icefish.
The Working Group noted that a feature common to all the species of icefish studied was significant asymmetry between left and right otoliths.
This analysis could extend the database intothe winter season and may result in additional information of icefish cohort strength.
There was also concern about previous in situ estimates of icefish TS(WG-FSA-SAM-04/9) because of uncertainty about target identification.
These data suggest that warp strikes pose minimal risk to seabirds in the Subarea 48.3 icefish trawl fishery.
Some stocks have been depleted further than intended(i.e. icefish in Subareas 48.1 and 48.2) and in consequence these are closed to directed fishing.
Observations on the finfish species caught, seabird and cetacean encounters andalso acoustic data were collected on icefish and krill.
Mackerel icefish(Champsocephalus gunnari), Antarctic rockcods(Trematomus spp.) and blackfin icefish(Chaenocephalus aceratus) are considered depleted.
These by-catch conditions apply to all new or exploratory fisheries,to established icefish fisheries and to demersal fisheries.
Dr Collins pointed out that icefish were often moribund when caught in trawls, but some may be in suitable condition to allow ex situ TS measurements on the research vessel.
Secondly, there was a growing awareness of the potential ecosystem dynamics between fur seals, icefish and krill which go well beyond single-species approaches.
WG-FSA noted that the focus of SG-ASAM regarding the work of WG-FSA should remain with resolving difficulties identified with the estimation of icefish abundance.
A total of 56 observation programs were undertaken, including 50 in 182 toothfish and icefish fisheries(40 longline, 9 finfish trawl and 1 pot gear fishing) and 6 on krill fishing vessels.
SG-ASAM recommended that further work be undertaken to obtain density and sound-speed measurements for a rangeof Antarctic fish species, including icefish and myctophids.
Icefish: 10 of combined icefish species every set Do focused data collection aiming at detecting any potential length-frequency change through time, toothfish already carried out yearly.
The Working Group requested that sensitivity tests be considered to evaluate the impact of uncertainty in icefish growth on the length-based assessment.
