A selectively bred carp strain is boosting productivity and profits across polyculture ponds in Bangladesh, improving overall pond performance in smallholder systems. A recently completed study shows that the third generation (G3) rohu, developed by WorldFish, grows 32.6% faster than conventional local fish and increases net margins by 24.8% for farmers, with higher total production and revenue across polyculture pond systems.

A new investigation reveals the significant potential of hydrochars, derived from common biowastes like sewage sludge and chicken manure, to function as effective slow-release phosphorus fertilizers. These findings offer a dual advantage for agriculture: enhancing crop productivity while simultaneously addressing challenges of waste management and environmental sustainability. Traditional phosphorus fertilizers often contribute to nutrient leaching and water pollution, prompting a global search for more environmentally sound solutions. This research presents a compelling case for hydrochars as a promising pathway toward a regenerative agricultural system.
