Synopsis (short abstract) In October and November 2010, the R/V Dr. Fridtjof Nansen conducted two offshore fisheries resource surveys in Paksitan¿s waters. These included sampling by acoustics, pelagic trawling, demersal trawling and collected a suite of concurrent biological and physical oceanography observations. Preliminary analyses presented in this cruise report include the distribution maps, catch rate estimates and raw abundance information for many stocks of interest to fisheries. Further analysis and comparison with historical data will be provided in later reports. The mesopelagic biomass estimated from these preliminary analyses is substantially lower than in previous surveys and further investigations in this regard are required. Of interest in the overview of some key oceanographic parameters is the presence of an hypoxic layer in deep waters (offshelf) which has been reported in earlier surveys and oceanographic studies. Some evidence of flood-induced productivity was also de tected in the near-shelf waters off Sindh.

    The FAO Workshop on the Status of Shared Fisheries Resources in the Northern Arabian Sea ¿ Iran (Islamic Republic of), Oman and Pakistan was held in Muscat, Oman, from 13 to 15 December 2010. In the last three years, the Government of Pakistan, and especially the Marine Fisheries Department in Karachi, has invested to reinvigorate the stock assessment capacity of the department. A multiyear project involving stock assessments, including marine surveys, is in place through technical a ssistance from the FAO. Even at this early stage, the new data have largely confirmed the parlous state of many of Pakistan¿s marine fishery resources and leave little doubt that overexploitation is the principal reason for this. More work is needed, and much is already under way, to provide clear and specific management recommendations, but the direction and scope of the action needed is already clear. Some of the most valuable resources in question are not limited to Pakistan¿s water s but are shared with regional neighbours or more widely on the high seas. Effective action to ensure sustainable fisheries in Pakistan can only come about if those sharing the resources act in concert. To this end, the Government of Pakistan proposed that the FAO convene a meeting with the two neighbours most immediately affecting Pakistan¿s shared marine resources ¿ Iran (Islamic Republic of) and Oman. The meeting was to identify the stocks of most concern in this regard, look into immediate ways to coordinate and improve the stock assessment efforts among the three countries, and to look forward to ways to set and achieve management goals jointly for these shared resources. To support the convening of this meeting, the FAO Unilateral Trust Fund (UTF) project ¿Support to Fishery Resources Appraisal in Pakistan¿ sponsored the travel and expenses of the meeting, and the Sultanate of Oman graciously agreed to host the meeting in Muscat.
