Smallholder fish farmers population census report 2020: Northern and Luapula provinces, Zambia

In total, 2341 smallholder farmers participated in the census: 61% in Northern Province and 39% in Luapula Province. Of the overall total, most (72.1%) were actively involved in fish farming, while the rest had abandoned the practice at the time of the census. Most of the farmers were men. The average age of the farmers was approximately 44.3, with young farmers (defined as farmers aged between 15 and 35 years old) accounting for less than one-third of the total. Regarding school, the largest share of farmers had received primary education, while only a handful had tertiary education.

Step-by-step guide to conducting digital surveys for aquaculture performance assessment

The WorldFish objective for sustainable aquaculture within the CGIAR Research Program on Fish Agri-Food Systems (FISH) focuses on enabling enterprises to progressively enhance production of aquatic foods in a more efficient and sustainable way. This is achieved by using domesticated, selectively bred, healthy fish reared on sustainable feeds in gender-inclusive production systems that have low carbon footprints with limited adverse environmental impacts.

WorldFish in Tanzania

Fisheries are an important source of food, income and nutrition in Tanzania, where 25% of the country’s population depends on coastal resources or inland lakes for their livelihoods. Over 180,000 people are employed in the fisheries sector, with a further 19,223 people involved in fish farming. WorldFish is working with the Tanzanian government and development partners to increase aquaculture production, reduce postharvest fish losses and enhance the role of fish in nutrition.

Measuring individual feed efficiency and its correlations with performance traits in Nile tilapia, Oreochromis niloticus

Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets (1.63 mg on average) eaten by individual tilapia (Oreochromis niloticus) held in 8 mixed sex groups of 15 fish were measured from video recordings made over a period of 10 days where fish were fed twice daily to achieve compensatory growth after 10 days of fasting.

Integration of mapping and socio-economic status of cage culture: Towards balancing lake-use and culture fisheries in Lake Victoria, Kenya

The present study aimed to map the presence of cages and to profile the socio-economic characteristics of their owners in Lake Victoria Basin Kenya as baseline information to aid in the formation of policies to manage the integration of capture and culture fisheries.

Increasing fish farm profitability through aquaculture best management practice training in Egypt

Egyptian aquaculture production has grown rapidly to over one million tons per year so that it now provides most of the country's fish supply. However, Egyptian fish farmers have received little extension advice or training. An intervention starting in 2012 aimed to address this gap by providing best management practice (BMP) training for pondbased tilapia monoculture and tilapia-mullet polyculture fish farmers.

The impacts of integrated homestead pond-dike systems in relation to production, consumption and seasonality in central north Bangladesh

The roles of homestead ponds and surrounding dike production of vegetables on farms in peri-urban and rural communities in central north Bangladesh were assessed. The study supports the view that small homestead ponds can contribute to the wider food supply, and that such “quasi-peasant” forms of aquaculture contribute to reduced poverty and enhanced dietary diversity and food security in the broader population.
