Multilateral consensus forged among heads of states must be value-additive and relevant at the national level to facilitate on-ground implementation. Yet, despite general optimism and advances in policy understanding, multi-scale diffusion remains a challenge with little certainty in outcomes. This study focuses on examining intermediary dynamics occurring within national policy apparatus that can influence domestic uptake of policy innovation.

Saprolegniosis is a worldwide fungal-like infection affecting freshwater fishes and their eggs. Reports show high mortalities and subsequent economic losses annually from Saprolegnia infections. Most therapeutants against Saprolegnia spp. infections are inefficient and some have negative impact on the environment. In this study, we have investigated the ability of boric acid (BA) to prevent Saprolegniainfection in Nile tilapia (Oreochromis niloticus). BA inhibited radial growth of Saprolegnia hyphae in vitro. Complete in vitro growth inhibition was found at a concentration of ≥0.6 g/L.

A fishers’ women-led Participatory Action Research (PAR) was conducted in 30 homestead ponds to assess the potential for polyculture of Tilapia (Oreochromis niloticus) and major carps Rohu (Labeo rohita) and Catla (Catla catla) in two coastal fishing villages of Bangladesh. Three treatments, namely T1 (Tilapia 200 fish per decimal; 1 decimal=40 m2), T2 (Tilapia 200+ Rohu 32+ Catla 8 fish per decimal) and T3 (Tilapia 200+ Rohu 8+ Catla 32 fish per decimal), each with 5 replicates, were tried in Hossainpur and Anipara villages.

Baseline and end-line data collected following the introduction and implementation of pond polyculture as part of the nutrition-sensitive fish agri-food systems approach to improve food and nutrition security in Luwingu, Northern Province, Zambia.

The first phase of the project, “Demand for seafood safety and environmental sustainability certification standards in sub-Saharan Africa: the case of Nigeria”, was implemented by WorldFish Center in collaboration with three other partners in eight states in Nigeria from August to November 2019. The willingness to pay experiments were conducted from October to November 2019. The objective was to evaluate demand for aquaculture certification and to examine the effect of expectations-based reference points on willingness to pay for aquaculture certification.

A growing human population combined with a higher per capita consumption of fish has resulted in a greater demand for finfish. Fisheries production has plateaued over the last 30 years; thus, improving productivity in aquaculture to meet future market demands is vital. In particular, demand has increased for tilapia, the second most important group of commercially farmed finfish globally, due to their hardiness, low feed requirements and environmental adaptability.

Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated and farmed aquaculture species globally, farmed throughout Asia, North and South America, and its African native range. In Egypt, a breeding program established the Abbassa strain (AS) of Nile tilapia in 2002 based on local broodstock sourced from the Nile River.
