A RISK MANAGEMENT FRAMEWORK FOR AVOIDING SIGNIFICANT ADVERSE IMPACTS OF BOTTOM FISHING GEAR ON VULNERABLE MARINE ECOSYSTEMS
adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems (VMEs) are avoided. Due to the high ... levels of uncertainty surrounding both the evidence of VME presence and the consequences of interaction ... with different types of gear, a risk management framework is proposed, similar to that which has been ... used successfully by IMAF to minimise the effects of longline fishing mortality on seabirds. The aim of ...

Summary of the toothfish fishery and tagging program in the Ross Sea region (Subarea 88.1 and SSRUs 882A–B) through 2017/18
SSRUs 88.2AB) together with biological characteristics of the catch of Antarctic toothfish through the ... 2018 season. Despite 2018 being the first year of implementation of the Ross Sea region Marine ... Protected Area, most of fishing effort was carried out in the historically fished areas. There was a small ... amount of effort in the northern area of SSRU 88.2A, which was opened to the exploratory fishery with the ...

On acceptable scattering of longlines geo-referencing in the toothfish fishery in the CAMLR Convention Area
Abstract: The issues of longlines geo-referencing during the exploratory fisheries of the ... toothfish in the Convention Area are discussed. Cases of differences in the coordinates of settings and ... haulings are considered. The estimation of the maximum possible variation of the coordinates in the depths ... range of 550-3000 m was performed. It is shown that the differences of coordinates of settings and ...

Analysis of variables influencing finfish by-catch in the krill fishery in Area 48
Abstract: This report presents the results of a method used to explore potential explanatory ... variables influencing finfish bycatch in the krill fishery of Area 48. Records of finfish bycatch in the ... -2011/12. The majority of fish caught were either small juveniles or larvae, dominated by Myctophidae ...

Preliminary investigations of an assessment model for skates and rays in the Ross Sea
Antarctic skates in SSRUs 88.1H, 88.1I, 88.1J, & 88.1K of the Ross Sea. The developmental model ... attempted to create a catch history of all skates and rays in the Ross Sea, and integrate these data with ... assessment model. We conclude that aspects of the catch history were very uncertain, including the species ... composition, the weight and number of skates caught, the proportion discarded, and the survival of those ...

Entanglement of Antarctic fur seals Arctocephalus gazella in man made debris at Signy Island, South Orkney Islands, 1998/99
Abstract: The results of the third annual survey of entanglement of Antarctic fur seals at Signy ... Island, South Orkney Islands are reported for the 1998/99 summer season. There were ten sightings of ... seals wearing neck collars of man-made debris, although one individual was observed twice and another ... observed on three separate occasions. Two additional sightings were of animals that had been previously ...

Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
Abstract: The upper-arm of the length-dependent fishing selectivity function for trawlers fishing ... for Patagonian toothfish around Heard Island (Division 58.5.2) was modelled as the exponential of a ... from commercial operations of each of trawlers and longliners fishing concurrently for 3 seasons ... assuming that, for the upper range of lengths, fish are fully selected by longliners but not by trawlers ...

An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort
this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...
