The National Sea Grant College Program is a matching fund program of the National Oceanic and Atmospheric Administration (NOAA) in the U.S. Department of Commerce. It provides a partnership of government, universities and industry working for economic development and appropriate use of marine and coastal resources of the U.S.A. SGNET, the Sea Grant Electronic Information Network, was established in June 1981 to enhance the timely and efficient exchange of information appli cable to the management, operation and conduct of the National Sea Grant College Program.
Change has become a pervasive global force with implications for the sustainability of social–ecological systems. In this context, understanding how much disturbance systems can absorb, where critical thresholds lie, and what systems might look like if a threshold is crossed are critical research questions. This paper explores resilience and social thresholds in two coastal communities in Mozambique by having fishers define their system identity, identify potential system thresholds, and explain how they would respond to crossing a threshold.
Catch-per-effort and length-frequency data on threadfin bream Nemipterus japonicus (Nemipteridae) supplied by the staff of the R/V Dr. Fridtjof Nansen, covering the period September 1983 to June 1984, were analyzed using the NANPACK and Compleat ELEFAN softwares. The seasonal, zonal and depth-wise distribution of N. japonicus is presented and discussed and the growth parameters L8 and K that were estimated are compared with estimates from other areas of the Indo-Pacific.
The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability of people in four villages that are experiencing different levels of soil salinity.
South-East Asia has traditionally been the global centre of production of tropical sea cucumbers for Chinese markets. Early research into culture methods took place outside this region, notably in India, the Pacific region and China. However, recent investment in Holothuria scabra (sandfish) culture has led to some significant advances within this region. The Philippines and Vietnam have been at the forefront of recent efforts, with involvement from substantial national programs and local institutions as well as international donors and scientific organisations.
This CGIAR Research Program’s vision is for the health, livelihoods and future prospects of the poor and vulnerable, especially women and children, to be transformed through consumption of adequate amounts of meat, milk and/or fish and from benefiting from the associated animal source food value chains. CRP3.7 aims to realize this vision by seizing upon an unprecedented opportunity to integrate and exploit three ongoing revolutions – the Livestock Revolution, the Blue Revolution and the Gene Revolution.
A simple plan is outlined to assist in the design of water quality research and monitoring programmes at aquacultureresearch stations. Before monitoring any programme, a decision on the goals of the aquaculture research to be performed is crucial to planning; the plan follows two major pathways--fish yield parameters-water quality checkingprogramme; and, water quality parameters/water quality research programme.
While an overwhelming majority of sub-Saharan African countries exhibit serious weaknesses in statistics pertaining to crop and livestock sectors, the deficiencies in terms of nationallyrepresentative data on the fishery sector are even more acute. The very little data available on the sector are essentially derived from case studies of selected fisheries, and the limited nationally representative data available are generally derived from a few questions included in the livestock section of household surveys.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is increasingly using the language of transformation to describe its aims and approach to achieving lasting impact at scale. Clarity on what AAS means by “transformation” is important to ensure that use of the term is intentional and meaningful. AAS wants to avoid the risk befalling a number of terms used in the development field-i.e., empowerment and participation-which are applied by such a wide range of actors with divergent intent and ideology that the terms lose meaning.
