Interactions of Patagonian Toothfish Fisheries With
CCAMLR Science, Vol. 17 (2010): 179–195 INTERACTIONS OF PATAGONIAN TOOTHFISH FISHERIES WITH KILLER AND SPERM WHALES IN THE CROZET ISLANDS EXCLUSIVE ECONOMIC ZONE: AN ASSESSMENT OF DEPREDATION LEVELS AND INSIGHTS ON POSSIBLE MITIGATION STRATEGIES P. Tixier1, N. Gasco2, G. Duhamel2, M. Viviant1, M. Authier1 and C. Guinet1 1 Centre d’Etudes Biologiques de Chizé CNRS, UPR 1934 Villiers-en-Bois, 79360 France Email – [email protected] 2 MNHN Paris, 75005 France Abstract Within the Crozet Islands Exclusive Economic Zone (EEZ), the Patagonian toothfish (Dissostichus eleginoides) longline fishery is exposed to high levels of depredation by killer (Orcinus orca) and sperm whales (Physeter macrocephalus). From 2003 to 2008, sperm whales alone, killer whales alone, and the two species co-occurring were observed on 32.6%, 18.6% and 23.4% respectively of the 4 289 hauled lines. It was estimated that a total of 571 tonnes (€4.8 million) of Patagonian toothfish were lost due to depredation by killer whales and both killer and sperm whales. Killer whales were found to be responsible for the largest part of this loss (>75%), while sperm whales had a lower impact (>25%). Photo-identification data revealed 35 killer whales belonging to four different pods were involved in 81.3% of the interactions. Significant variations of interaction rates with killer whales were detected between vessels suggesting the influence of operational factors on depredation. When killer whales were absent at the beginning of the line hauling process, short lines (<5 000 m) provided higher yield and were significantly less impacted by depredation than longer lines. -

Toothfish species are key predators of cephalopods and may be 19 viewed as ideal biological samplers of these species. A total of 256 cephalopod lower 20 beaks were identified from the stomachs of Patagonian (Dissostichus eleginoides) and 21 Antarctic toothfish (D. mawsoni), captured in fisheries of South Georgia and the 22 South Sandwich Islands in the South Atlantic. Long-armed octopus squid 23 (Kondakovia longimana) and smooth-hooked squid (Moroteuthis knipovitchi) were 24 the main cephalopod prey and both were predated upon wherever toothfish were 25 captured, though inhabit deeper waters at the South Sandwich Islands than at South 26 Georgia.

The term Elasmobranchs or chondrichthyans refers to the The great majority of the commercially important species of group of marine organisms with a skeleton made of cartilage. chondrichthyans are elasmobranchs. The latter are named They include sharks, skates, rays and chimaeras. These for their plated gills which communicate to the exterior by organisms are characterised by and differ from their sister 5–7 openings. In total, there are about 869+ extant species group of bony fishes in the characteristics like cartilaginous of elasmobranchs, with about 400+ of those being sharks skeleton, absence of swim bladders and presence of five and the rest skates and rays. Taxonomy is also perhaps to seven pairs of naked gill slits that are not covered by an infamously known for its constant, yet essential, revisions operculum. The chondrichthyans which are placed in Class of the relationships and identity of different organisms. Elasmobranchii are grouped into two main subdivisions Classification of elasmobranchs certainly does not evade this Holocephalii (Chimaeras or ratfishes and elephant fishes) process, and species are sometimes lumped in with other with three families and approximately 37 species inhabiting species, or renamed, or assigned to different families and deep cool waters; and the Elasmobranchii, which is a large, other taxonomic groupings. It is certain, however, that such diverse group (sharks, skates and rays) with representatives revisions will clarify our view of the taxonomy and phylogeny in all types of environments, from fresh waters to the bottom (evolutionary relationships) of elasmobranchs, leading to a of marine trenches and from polar regions to warm tropical better understanding of how these creatures evolved. -

The emphasis has been on fishes generally but these studies have also contributed greatly to our knowledge of chondrichthyans in the region, as well as across the broader Indo–West Pacific. An annotated checklist of cartilaginous fishes of the Philippines is compiled based on historical information and new data. A Taiwanese deepwater trawl survey off Luzon in 1995 produced specimens of 15 species including 12 new records for the Philippines and a few species new to science. -
Catch and Effort Data
Chapter 11: The Inland Waters River Fishery Information System CHAPTER 11: INLAND WATERS RIVER FISHERY INFORMATION SYSTEM 11.1 Background The Inland Waters River fishery is a multi-species, multi-gear fishery encompassing the South Australian sector of the River Murray and its backwaters (Map 11.1). Historically, the fishery was based on harvesting Murray cod (Maccullochella peelii peelii), golden perch (Macquaria ambigua), and bony bream (Nematalosa erebi). The fishery was restructured in July 2003 to a non-native dominate fishery and the commercial fishing for significant native species is now prohibited. The fishery is now based predominantly on the taking European carp (Cyprinus carpio) and redfin perch (Perca fluviatilis). There are a total of 6 licence holders who operate within the fishery. Prior to the restructure 30 license holders fished the river, each with a designated reach. Up to December 2007 SARDI production tables hold in excess of 270,000 daily records. Data is held from 1984/85 to current and is continually being updated. Refer to Figure 11.3 for an entity relationship diagram of the inland waters system that encompasses the River Fishery.
