Barracouta Scientific name: Thyrsites atun Other names: maka, makaa, mangaa (Maori), couta, snoek. Ranking: E (Red - Avoid) Description: Barracouta is a relatively short-lived species that is related to gemfish. It is widely distributed in the Southern oceans and whilst abundant in New Zealand‟s cooler waters south of Cook Strait, they also occur in our northern waters, ranging from shallow inshore areas to depths of 200m. Once an undesirable bycatch species, barracouta are now an important part of trawl fishery catches. Ecological concerns: The damage done to large areas of the seabed by bottom trawling, poor knowledge of stock boundaries, limited research, lack of a management plan and uncertainty over the sustainability of the current catch limit and recent catches. Bycatch of NZ fur seals, albatrosses and petrels, non-target fish plus removal of this important predator species on food webs are also of concern. Economic value: Main markets include Japan, China, Papua New Guinea, and South Africa. Total exports worth $28 million in 2008. ASSESSMENT OUTPUT Biology and risk of overfishing (score B) Distribution: Mainly found off the South, Chatham, Stewart and Snares Islands to depths of 200m. Maximum age (years): 10. Age at sexual maturity: 2-3. Growth rate: Moderate to fast. Reproductive output: High to very high. Age exploited: 3 (uncertain) Status and sustainability of fish catches (score D) Population size: Unknown. Annual catch limit: Set at 32,662 tonnes in 2001-02. Recorded catch: Reported landings of 27,968 tonnes in 2007-08 were well under the peak landings of 47,000 tonnes reported in 1977. The catch for BAR 5 has exceeded the TACC by up to 25% in three of the last four years. Stock trends: Unknown. A decline in Southland was indicated from trawl surveys in the 1990‟s, but surveys have since been cancelled. MSY Status: Unknown. The Ministry of Fisheries assessment plenary report states: “Estimates of current and reference biomass are not available for any barracouta stocks and therefore it is not known if current TACCs and recent catches are sustainable or whether they are at levels which will allow the stocks to move towards a size that will support the maximum sustainable yield.” (MFish, 2009, p62). Impact of fishing method and protected, threatened and endangered species captures (score E and D) Fishing Method: Bottom trawling. Habitat damage: Large areas of benthic communities are damaged by bottom trawling, including bryozoans and crabs. Bycatch: Non-target fish species such as silver warehou and spiny dogfish and a significant bycatch in Southland of NZ fur seals, white-capped (shy) albatrosses and sooty shearwaters. Ecological effects: Fishing for barracouta removes an important predator from food webs. Management and management unit (score D and C) Quota Management Species: Yes, since 1986. Catch limits: Yes. Management plan: No. Management component: Single species Stock assessment: No quantitative assessment. Yield estimates based on average catch have not been reviewed since 1992.
