Potential Application of Linear Programming Method and Solid‐State Fermentation in Improving the Quality of Fish Feed and Profits of Small‐Scale Nile Tilapia (Oreochromis niloticus) Farming in Tanzania

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT The scarcity of affordable and high‐quality fish feeds limits aquaculture development in many developing countries. The present study assessed the use of linear programming (LP) techniques for formulating Nile tilapia (Oreochromis niloticus) diets and solid‐state fermentation (SSF) technology to improve their nutritional value.

Do Adverse Events Influence Time Preferences? Evidence From Smallholder African Farmers

Journal of Agricultural Economics, Volume 77, Issue 1, Page 130-155, February 2026.
ABSTRACT Time preferences play a critical role in the agri‐food value chains of low‐income countries, impacting the choices of local operators, including innovation uptake. This paper assesses the association between smallholder farmers' individual characteristics, their exposure to diverse adverse events, and their intertemporal choices using in‐the ...

Effects of Increased Water Salinity and Temperature on the Development of Rainbow Trout Fry Syndrome (RTFS) Caused by Flavobacterium psychrophilum

Journal of Fish Diseases, Volume 49, Issue 2, February 2026.
ABSTRACT Flavobacterium psychrophilum, the etiological agent of Rainbow Trout Fry Syndrome (RTFS) and Bacterial Coldwater Disease (BCWD), causes varying degrees of disease and mortality in salmonid aquaculture worldwide. Because its treatment relies on the use of antimicrobials, alternative interventions are of environmental and economic interest.
