Baseline and end-line data collected following the introduction and implementation of pond polyculture as part of the nutrition-sensitive fish agri-food systems approach to improve food and nutrition security in Luwingu, Northern Province, Zambia.

The first phase of the project, “Demand for seafood safety and environmental sustainability certification standards in sub-Saharan Africa: the case of Nigeria”, was implemented by WorldFish Center in collaboration with three other partners in eight states in Nigeria from August to November 2019. The willingness to pay experiments were conducted from October to November 2019. The objective was to evaluate demand for aquaculture certification and to examine the effect of expectations-based reference points on willingness to pay for aquaculture certification.

A growing human population combined with a higher per capita consumption of fish has resulted in a greater demand for finfish. Fisheries production has plateaued over the last 30 years; thus, improving productivity in aquaculture to meet future market demands is vital. In particular, demand has increased for tilapia, the second most important group of commercially farmed finfish globally, due to their hardiness, low feed requirements and environmental adaptability.

Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated and farmed aquaculture species globally, farmed throughout Asia, North and South America, and its African native range. In Egypt, a breeding program established the Abbassa strain (AS) of Nile tilapia in 2002 based on local broodstock sourced from the Nile River.

Pond water quality data at the National Aquaculture Research and Development centre in Mwekera. With a particular focus on temperature and dissolved oxygen to inform mating of the three-spotted tilapia in ponds.

Each country dataset provides information on national per capita fish consumption, and some countries have fish consumption broken down by vulnerable groups.

Productivity among small- and medium-scale tilapia farms varies considerably. The difference between the best performers and lower ones (yield gap), is affected by differences in growth rate and feed conversion ratio (FCR). FCR at the farm level is strongly influenced by survival of fish. In this study a systematic literature review of two databases (ASFA and CAB-Abstracts) identified 1973 potentially relevant articles.

The survey was implemented to assess on-farm performance of aquaculture fish production systems in Nigeria. The primary sampling unit was aquaculture farming households/farms. The survey comprised the following modules: (1) farmer characteristics; (2) aquaculture production and marketing activities including input use and cost as well as output harvested and sold; (3) Aquaculture experience, change and livelihoods; (4) aquaculture credit and association; (5) food safety and willingness to participate in aquaculture certification; Data on aquaculture production were collected at farm level.
