WorldFish Incubator bridges the gap between scientific research and business by supporting investment in sustainable small- and medium-sized aquaculture enterprises in Africa, Asia and the Pacific. By building opportunities for growth, WorldFish Incubator connects small-scale aquaculture enterprises in Africa, Asia and the Pacific with investors seeking scalable, high-impact, bottom-line investments in aquaculture.

The omnivorous African sharptooth catfish is a valuable species suitable for culture by smallholder farmers in Cameroon. A five-year research project that brought farmers together with research interests established simple, but effective approaches to increasing catfish fingerling production through improved egg handling, antipredation measures, and higher-density stocking options.
To diagnose inhibition of egg hatchability by rainfall and water stagnation, some incubating eggs were protected against the physical impact of raindrops, some were subjected to various turbidity levels and others, to various incubation densities (number of eggs/litre of water) in flowing vs stagnant water. Data analyses showed that, unaffected by raindrop (P> 0.05), hatchability was inversely proportional to both turbidity (coefficient=-0.971) and incubation density (coefficient= -0.973). Only the properly constructed ponds (i.e.
To determine how best smallholders could maximize the profitability of their catfish hatcheries, the cost/benefit analyses of using fences, hapas and bird nets to exclude predators; as well as over-stocking to create food shortage, were conducted. As compared to the typical production system (fertilized unfenced ponds) and at a stocking density of 10 two-day old fry/m2, survival increased by 28% in fenced ponds, 34% in open hapas and 55% in bird-netted hapas.
WorldFish Incubator is a new and innovative program designed to support investment into sustainable small and medium-sized aquaculture enterprises in developing countries. It identifies suitable projects and facilitates technical and financial assistance, offering nurturing in sustainable aquaculture through its network of contacts. By leveraging the benefits of scale, WorldFish Incubator will help the aquaculture sector deliver on its promise to meet the growing demand for fish whilst ensuring equitable supplies and access for the poor.
