Summary: Nile tilapia is the third-most important fish species in global aquaculture and plays a crucial role in addressing food security in developing countries. Africa possesses rich natural genetic resources, but its aquaculture production is dominated by Asian countries. The genetic diversity of wild Nile tilapia populations in Africa is at risk and conservation strategies are needed.

Summary: The study found that fucoidan can significantly improve the growth, feed conversion ratio, and survival rate of Nile tilapia while combating the toxic effects of atrazine. Fish treated with fucoidan showed enhanced intestinal villi, while those exposed to atrazine exhibited significant deterioration in intestinal structure.

Summary: The immune-suppressed model of Nile tilapia can be induced by intraperitoneal injection of Cyclophosphamide at a dosage of 200 mg/kg BW, leading to significant decreases in various immune-related parameters.

Summary: The study identified a lect2 gene from Nile tilapia (On-lect2) and characterized its roles in the fish's immune response against bacterial infection. On-LECT2 plays important functions in promoting inflammation, reducing tissue damages, and improving survival rate of Nile tilapia during bacterial infection, with the highest transcriptional levels in the liver.

Summary: This study analyzed the impact of Nile tilapia invasion on the trophic structure of native species and found that it disrupted the stability of the recipient ecosystem. The widespread introduction of non-native species, including aquaculture species, can modify the trophic structure of communities and threaten biodiversity and ecosystem functioning.

Summary: This study examines the genetic consequences of introducing Nile tilapia into the Congo Basin, finding evidence of genetic admixture with other tilapia species and the potential threat to the genetic integrity of native tilapias. The study also identifies genetic differentiation between Nile tilapia populations from different regions, suggesting independent introductions. The authors recommend avoiding further introductions of Nile tilapia in non-native regions and using native tilapias in future aquaculture efforts.

Summary: This study evaluated the use of marine diatom Thalassiosira weissflogii as a dietary additive in seawater-tolerant Nile Tilapia. The results showed that the moderate supplementation of marine diatom could promote fish growth and increase the content of omega-3 fatty acids.

Summary: Exposure to Butylparaben (BuP) induces darker skin pigmentation in Nile tilapia by interfering with melanin synthesis genes and neurotransmitter levels. BuP inhibits phototransduction from the retina to the brain, resulting in increased melanin synthesis and decreased opsin expression.

Summary: The potential of pine pollen (PP) to masculinize Nile tilapia was evaluated in this study. The results showed that both PP and 17 alpha-methyltestosterone (MT) treatments significantly skewed the sex ratio towards more male individuals, with 1.28 g PP kg-1 diet producing the highest masculinization rate. Furthermore, the PP and MT-supplemented feeds promoted the growth of Nile tilapia, with 3.20 g PP kg-1 diet resulting in the highest final weight.

Summary: This study discovered an IL8 gene from Nile tilapia and found that it plays a crucial role in acute bacterial infections. The gene codes for 94 amino acids and is highly expressed in the head-kidney tissue and induced by Streptococcus agalactiae and Aeromonas hydrophila. In vitro experiments showed that IL8 regulates various immune processes and promotes inflammation. These findings are significant for further understanding the protective effects of IL8 in bony fish against bacterial infections.
