Synopsis (short abstract) Cage aquaculture has grown rapidly during the past decades and there has been a move towards the development and use of more intensive cage-farming systems to access and expand into untapped open water areas, particularly in marine offshore waters. Fish cages vary in design, size and material used as they have been designed for employment in diverse environments, ranging from relatively protected to highly exposed and dynamic sites, either as floating or fully submerged structures. This technica l manual focuses on the high density polyethylene (HDPE) cages as they are widely used in modern-industrial marine aquaculture in many parts of the world. It provides the reader with highly practical and technical information on the design and components of a typical HDPE cage, on how a cage collar is assembled and the net pen installed. Along with the structure of the cage, comprehensive information on the grid mooring system and installation is provided. Finally, information on farming operati ons that includes maintenance and control of the farming structures, stocking of the farmed fish, feeding, harvesting and packaging are discussed along with other practical aspects and routine management operations.

    Piloting Marine Cage Farm as a Social Business Brief 2018

    Under the project “Strengthening resilience and livelihoods of Gazan fishing communities through promoting the establishment of a marine cage farming social business”, the Government of Italy is joining forces with the Food and Agriculture Organization of the United Nations (FAO), and the Ministry of Agriculture’s Department of Fisheries, to establish a pilot marine cage farm off the coast of the Gaza Strip. The Government of Italy is providing EUR 2 million to address the long-term needs of Gazan fishing communities. Food security and livelihoods in Gaza have been severely impacted by restrictions on the movement of people and goods and access to land and water. Fishers are among the most vulnerable communities experiencing high poverty levels, and high production costs associated with traditional fishing methods and low labour productivity. The establishment of this marine aquaculture zone is intended to encourage the future expansion of the marine aquaculture sector in the Gaza Strip.

    Report of the Regional Technical Workshop on Sustainable Marine Cage Aquaculture Development. Muscat, Sultanate of Oman, 25–26 January 2009 2009

    The Regional Commission for Fisheries (RECOFI) Regional Technical Workshop on Sustainable Marine Cage Aquaculture Development, held from 25 to 26 January 2009 in Muscat, Sultanate of Oman, was organized in view of the growing importance and interest of this aquaculture sub-sector across the region. The workshop focus was on environmental impact assessment and monitoring, and aquaculture licensing for marine aquaculture cage systems and aimed at identifying constraints and shortcomings that requi red to be dealt with to support the development of the cage industry and facilitate investments from the private sector. The document contains a set of suggestions and recommendations with regards to technical and policy requirements needed to support the growth of the aquaculture sector as a whole and more specifically cage fish farming. The report also contains three review documents on marine cage aquaculture in the region, regulation of Norwegian net-cage fish farming, and a review on cage a quaculture licensing procedures prepared as background discussion papers for the workshop. With specific regard to environmental impact assessment (EIA) the discussions held at the workshop clearly indicate that there is a need for the region and individual Commission members to develop an ad hoc EIA format based on the conditions of the local marine environment. A proposed cage aquaculture licence procedure was discussed and proposed at the workshop based on the format developed and adopted by the Sultanate of Oman.
