Actinomycetes studies in Tunisia.

Tunisia, located in North Africa, has a diverse topography along the Mediterranean Sea to the Sahara Desert. These environments encompass oases, rhizosphere soils, desert deposits, saline wetlands, offshore oilrigs, and ancient monument rocks. The country's varied environments have led to the isolation of a multitude of actinomycetes.

Mitigation of cold stress in Nile tilapia (Oreochromis niloticus) through dietary lipids supplementation: a preliminary network meta-analysis.

There is a growing body of evidence suggesting that water temperature can significantly impact the dietary fatty acid requirements of Nile tilapia (Oreochromis niloticus). Therefore, this study assessed the effectiveness of different dietary lipid sources on the growth performance of Nile tilapia reared at suboptimal temperatures. A network meta-analysis was performed, including searches of PubMed and Scopus from inception to January 2022, for trials that evaluated the effects of lipid sources on cold-stressed Nile tilapia.
