Tilapia hatcheries are the most common type of fish hatchery in Egypt, as well as many other countries
globally. Their success has helped supply fish farms with quality tilapia seed, which in turn has increased
farmed fish production in many parts of the world. With the fish farming industry growing so quickly,
however, tilapia hatcheries must improve the quality of their seed production for fish farmers to maintain
their profit margins.
To this end, these guidelines document the most optimal, locally appropriate, management practices for

This is a blog about how Southern and Eastern Africa can capture genetic gains to improve resilience of farming systems through use of improved seed/stress-tolerant or climate-resilient seeds.

Sustainable soil nutrient management (SNM) is important for improving soil resources and food security in sub-Saharan African countries. Inherent livelihood diversity may lead to differences in household behavior in the adoption of SNM practices, thus challenging policy interventions uniformly implemented. This study aims at exploring the responsive heterogeneity in household behavior in the adoption of fertilizer use by farmers. Determinants of fertilizer uses were analyzed across different farm types.

Support to agriculture producers is provided in different forms, including border measures, domestic subsidies, and income transfers from taxpayers to producers. International Food Policy Research Institute (IFPRI) maintains a harmonized database on nominal rate of protection (NRP) for the AgIncentives Consortium (www.ag-incentives.org) constituted by OECD (Organization for Economic Co-operation and Development), FAO, IFPRI, the Inter-American Development Bank (IADB), and the World Bank.

This publication was prepared by the staff of the African Union Development Agency - NEPAD in partnership with experts from the Accelerating Impacts of CGIAR Research for Africa (AICCRA) Project, The findings, interpretations, and conclusions expressed in this work do not necessarily reflect the views of AUDA-NEPAD.

Moth bean (Vigna aconitifolia) is an orphan legume of Vigna genus, exhibiting wide adaptability and has the potential to grow well in arid and semi-arid areas, predominantly across different eco-geographical regions of Asia, particularly the Indian subcontinent. The inherent adaptive attributes of this crop have made it more tolerant towards a diverse array of abiotic and biotic stresses that commonly restrain yield among other Vigna species.

The Athi Kapiti conservancies and ranches wildlife game count was conducted on 4th June 2023. The count aimed at establishing the current wildlife population and spatial distribution in the Athi Kapiti landscape following concerns raised by landowners of declined wildlife populations in the area after a severe drought and increased human activities. Subsequent counts will help in identifying wildlife trends and possible impacts of the expanding and continuous anthropogenic activities that peril wildlife existence in the landscape.

WorldFish operates a transdisciplinary research-in-development program in Timor-Leste, hosted by the national government and the Directorate General of Fisheries, Aquaculture and Marine Resources (DG-FAMR). Two new projects started in Viqueque Municipality in 2022, working to support aquatic foods systems with nutrition-sensitive, inclusive and climate adaptation approaches. A workshop provided a platform to engage and consult with national, municipal and local partners, stakeholders and communities, aiming to strengthen partnerships at the municipality level.

"Shamba Shape Up" is a popular television show in East Africa that focuses on agricultural education and improvement. The show features a team of experts who visit different farms, providing practical demonstrations and advice to farmers on various aspects of agriculture, such as livestock rearing, crop cultivation, farm management techniques, and sustainable practices. It aims to educate and empower farmers with valuable information and skills to enhance productivity, increase yields, and improve their livelihoods.

This study determined the effect of pelagic Sargassum on in vitro dry matter and organic matter degradation, total gas production (TGP), and protozoa population. The treatments were different levels of Sargassum inclusion on a basal substrate (Stargrass hay; Cynodon nlemfuensis) as follows: T0 (control treatment based on Stargrass hay), T10 (90% Stargrass hay + 10% Sargassum), T20 (80% Stargrass hay + 20% Sargassum), and T30 (70% Stargrass hay + 30% Sargassum). Ruminal fermentation kinetics and protozoa population were determined during 72 h of in vitro incubations.

Depending on the trait architecture and reproduction system, selection strategies in plant breeding focus on the accumulation of additive, dominance effects, or both. Innovation in the exploitation of dominance‐effect‐based heterosis has been limited since the proposal of general combining ability (GCA)‐based approaches. We propose the use of a new surrogate of genetic complementation between genetic pools to increase accumulation of dominance effects and heterosis.
