F I S H E R Y S T A T U S R E P O R T S 2 0 0 6 111 permitting the harvesting of trepang by hand only. Analysis and monitoring of catch and effort trends, average weight of trepang caught, the continuation of fishing on the same grounds, operational and logistic constraints together with the continued focus on the premier species, the sandfish, indicate that the current arrangements are appropriate to achieve the management objectives of the NT Trepang Fishery. In addition, fishing the tropical inshore waters of the NT with its large tidal range (exceeding 8 m in some areas) and distinct wet/dry monsoon season and highly turbid water, also places operational limitations on the fishery and the collection of trepang by hand. Highly turbid water impedes the effectiveness of hand gathering, with commercial operators reporting the inability to harvest trepang during the time of spring (larger) tides and the heavy flooding often associated with the monsoon. As a result of these factors, actual fishing time is limited. These natural inhibitors are taken into consideration by management and acknowledged as providing further protection to the fishery. The Trepang Fishery is further managed in accordance with the management objectives, performance indicators, triggers and management actions as agreed through industry and the Australian Government assessment process and as part of the WTO accreditation. Current Issues Reported catch levels for target sandfish species Holothuria scabra throughout 2006 were within acceptable levels. Over the next 12 months NT Fisheries will be working with the licence owners to develop and implement finer scale data collection and reporting. This will enhance the quality of data collected and mitigate the potential risk of localised depletion of trepang in the fishery. Compliance Compliance activities associated with management arrangements for the Trepang Fishery are undertaken by the Marine and Fisheries Enforcement Section (MFES) of the NT Police, Fire and Emergency Services, under the NT Fisheries Act 1988. MFES effectively monitors and enforces the Trepang Fishery management arrangements through the inspection of vessel arrivals and departures through the single port of Darwin. Compliance includes verification of catch returns against processor returns (i.e. requirement for all operators to specify where they are selling their product). MFES has the power, if necessary, to investigate the records of wholesalers and licensees. In 2006, no significant compliance issues were recorded for this fishery. Consultation, Communication and Education Regular consultation occurs between NT Fisheries, licence holders and the NT Seafood Council. In addition, NT Fisheries staff conduct regular visits to the wharf to speak informally with fishers. Conservation groups and non-government organisations are updated on current fisheries issues, including the Trepang Fishery, through regular meetings with senior fisheries officers. Members of the public, including community and environment/conservation groups are also invited to provide their views to NT Fisheries through the release of public discussion papers and other consultative processes. NT Fisheries also issue publications in the form of Fisheries Reports and newsletters to inform and educate stakeholders.
