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.

Characterization of Bromelain‐Soluble Sheepskin (Ovis aries) Proteins and Effect of In Vitro Gastrointestinal Digestion on Angiotensin Converting Enzyme Inhibition Activity

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Novel bioactive peptides resulted from in vitro gastrointestinal digestion of soluble sheep skin protein. ABSTRACT This work characterizes proteins extracted from sheepskin using bromelain and examines angiotensin converting enzyme (ACE) inhibition activity of the peptides generated by in vitro gastrointestinal digestion (GID).

A Multimodal Approach to Identify Metallothionein Metal Inducers in Nile Tilapia: Insights From Molecular Docking and Hepatocyte Exposure

Journal of Applied Toxicology, Volume 46, Issue 2, Page 590-600, February 2026.
ABSTRACT Many human activities contribute to the pollution of aquatic ecosystems, primarily through agricultural, industrial, mining, and domestic discharges into water bodies. Fish, being highly sensitive to environmental changes, serve as valuable models for monitoring the health of these ecosystems.

Overview on the role of dietary Spirulina platensis on immune responses against Edwardsiellosis among Oreochromis niloticus fish farms

BMC Veterinary Research
Edwardsiellosis is a bacterial fish disease that mostly occurs in freshwater farms and is characterized by a high mortality rate. Edwardsiella tarda strain was recovered from 17 fish out of 50 Nile tilapia, which were harboring clinical signs of systemic

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 ...
