A tidal wave of interest is building in farming the seas. It’s part of a global rush to exploit oceanic resources that’s been dubbed the “blue acceleration.” Optimistic projections say that smart mariculture – fish farming at sea – could increase ocean fish and shellfish production by 21 million to 44 million metric tons by 2050, a 36%-74% jump from current yields. Other estimates suggest that an ocean aquaculture area the size of Lake Michigan might produce the same amount of seafood as all of the world’s wild-caught fisheries combined.
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.
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.
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.
The CGIAR Research Program on Fish Agri-Food Systems (FISH) focuses on the interlinked challenges of sustainable aquaculture and small-scale fisheries (SSFs), and enhancing the contribution of fish to poverty reduction, improved human nutrition and environmental management, with a geographical focus on Africa, Asia and the Pacific.
This paper reviews aquaculture production systems and fish health management practices in Kenya in order to establish and document actions needed to monitor, mitigate and regulate effectively for future fish health problems across the country.
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.
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.
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.
