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 scoping mission team was composed of 14 people representing research institutions (RUPP), government (FiA, IFReDI), NGOs (ANKO, ADIC) and CGIAR institutions (WorldFish and Bioversity). The scoping trip was carried out over a 7-day period from April 28 to May 4 within eight (8) communities in Kampong Thom, Siem Reap, Battambang, Pursat and Kampong Chhnang. In addition, panel discussions were held with local government, fishery, agriculture and water management institutions, NGOs, the private sector and communities, and were convened in Siem Reap, Battambang and Pursat.
Based on length-frequency distributions and mean annual water temperature, growth and mortality parameter estimates, as well as spawning pattern of Pellonula leonensis (Clupeidae) occurring in the Cross River (Nigeria) have been obtained. The estimated von Bertalanffy growth parameters are TL8 = 156 mm, and K = 0.81 - 0.96 year -1. Natural mortality ranges from M = 0.8 to 0.9 year-1. Spawning occurs during the whole year with a dominant peak in the dry season and a smaller peak early in the rainy season.
Where natural resources are a key component of the rural economy, the ability of the poor to realize their visions for the future depends significantly on institutional structures that govern resource access and management. This case study reports on an initiative on the shores of Lake Kariba in Zambia, where lakeshore residents face competition over fishing, tourism, and commercial aquaculture.
The CGIAR Research Program (CRP) Aquatic Agricultural Systems (AAS) will target five countries, including Solomon Islands. The proposed hubs for Solomon Islands were to cover most provinces, referencing the Western, Central and Eastern regions. Scoping of the initial ‘Central’ hub was undertaken in Guadalcanal, Malaita and Central Islands provinces and this report details findings from all three.
WorldFish is leading the CGIAR Research Program on Aquatic Agricultural Systems together with two other CGIAR Centers; the International Water Management Institute (IWMI) and Bioversity. In 2012 and 2013 the AAS Program rolled out in Solomon Islands, Zambia, Bangladesh, Cambodia and the Philippines. Aquatic Agricultural Systems are places where farming and fishing in freshwater and/or coastal ecosystems contribute significantly to household income and food security. The program goal is to improve the well-being of AAS-dependent people.
The Program will achieve impact at multiple scales (household, community, province and national as well as amongst program countries) through pathways that include partnerships, knowledge sharing and learning. In Solomon Islands significant benefits will be achieved through direct engagement with partners, including communities in specific research sites in selected program hubs. Of a total population of just over half a million people, 75% of Solomon Islanders are subsistence-oriented small holder farmers and fishers.
The CGIAR Research Program on Livestock and Fish started in January 2012. It aims to increase the productivity of small-scale livestock and fish systems in sustainable ways, making meat, milk and fish more available and affordable to poor consumers across the developing world. Genetics is one of the three technological components of the Livestock and Fish research program. A genetics team meeting was held on 30-31 July 2012, at the International Livestock Research Institute (ILRI), Nairobi.
