Summary: The study found that the non-native Nile tilapia exhibited greater aggression and dominance over the native Manyara tilapia in competitive interactions, potentially leading to changes in resource use and long-term habitat displacement.

Summary: The study found that feeding Nile tilapia fingerlings three times per day is more effective than feeding once or twice a day, as it increases the chance of feed intake and ingestive behavior leading to optimal growth.

Summary: Understanding the genetic relationship between economically important traits is crucial for breeding widely cultured species. This study found that the resistance to Francisellosis in Nile tilapia is controlled by additive genetic factors. The analysis also showed that there is a very low genetic correlation between harvest weight and resistance to Francisellosis, suggesting that selection for growth alone does not improve disease resistance.

Summary: Invasive African Nile tilapia has a significant impact on the biodiversity of freshwater systems, with indications of competitive effects on native species. This study in Mexico found that Nile tilapia is more active and aggressive than the native Mayan cichlid and that the latter's behavior is strongly influenced by the former. The Nile tilapia's broad environmental tolerance gives it an advantage over native species, which may contribute to its invasive success in a changing world.

Summary: This study investigates the effects of stocking larger-sized Nile Tilapia on water quality, growth performance, and economic yield, and finds that stocking larger-sized fish leads to better results in cage culture. The rural site shows more suitable conditions for aquaculture and stocking larger-sized fish has higher economic returns.

Summary: Recently, metal-based nanoparticles have gained attention as feed supplements in aquaculture and the fish feed industry. A study was conducted to evaluate the effect of chemically synthesized zinc oxide nanoparticles (ZnO-NPs) and zinc acetate on Nile tilapia fingerlings. The results showed that the diet supplemented with 40 mg/kg of ZnO-NPs demonstrated the best performance in terms of health parameters, oxidative status, and disease resistance.

Summary: The study evaluated the effects of a probiotic additive on tilapia growth by observing growth curves, muscle and adipose tissue morphology, carcass characteristics, and gene expression related to growth. The probiotic mixture significantly improved growth rates, feed conversion rate, and final weight of the tilapia. The additive promoted white muscle fiber hypertrophy, inhibited specific gene expressions, and increased intestinal villi, enhancing nutrient absorption and utilization.

Summary: The objective of this study was to evaluate the growth and reproductive performance of Nile tilapia broodstocks of Thai and GIFT strains in different weight classes. The GIFT strain showed better reproductive performance, and the weight group of approximately 900 g was found to be the most suitable for commercial reproduction and larviculture.

Summary: The study showed that Nile tilapia's absolute U-crit has a high heritability, and fish with higher U-crit tend to grow slower in non-aerated ponds.

Summary: The study found that propofol has longer induction and anesthesia duration compared to eugenol in fish anesthesia, while also having a faster recovery rate. In terms of hematological indices, the propofol group showed a transient increase compared to the eugenol group. However, there were no significant changes in other indicators such as leukocytic counts between the two groups. During anesthesia, both propofol and eugenol groups showed a temporary increase in glucose and cortisol levels, which returned to baseline levels during the recovery period.

Summary: Cannabidiol (CBD), derived from Cannabis sativa, has been widely studied for its neuroprotective effects in humans. This study investigated the effects of different CBD doses on the aggressiveness, stress, and reproductive development of Nile tilapia fish. The results showed that CBD supplementation reduced aggressiveness and non-social stress in a dose-dependent manner, while also increasing the gonadosomatic index. However, lower doses of CBD decreased the number of spermatozoa. Despite this effect, CBD supplementation has the potential to improve the welfare of animals in artificial environments.

Summary: This study evaluated the performance and cold tolerance of different Nile tilapia stocks at suboptimal temperatures and identified alleles of microsatellite markers associated with cold tolerance. Among the tested stocks, S5 and S7 tilapias showed lower mean death temperature in cold tolerance assay, while stocks S3, S6, and S7 exhibited higher growth rates at suboptimal temperatures.

Summary: In this study, a specific monoclonal antibody against Nile tilapia Ig lambda was prepared, which could recognize Ig lambda in serum and Ig lambda(+) B cells in tissues. The composition of IgM(+) and Ig lambda(+) B cell subsets was analyzed using this antibody and a mouse anti-tilapia IgM heavy chain antibody. The antibody level after immunization of Nile tilapia can be detected using this antibody, which lays a foundation for the evaluation of immunization effect of tilapia vaccine.

Summary: This study compared the different tolerance mechanisms to Streptococcus agalactiae in three tilapia lines through transcriptome analysis. The results showed that numerous metabolic and immune-related pathways were activated in all three tilapia lines 48 hours after infection. Hybrid tilapia exhibited stronger resistance to Streptococcus agalactiae, which was associated with differential expression of specific genes.
