One-Health is an umbrella term that integrates the health of environment, humans and non-human animals. This approach applied here to elucidate impact non-native invasive species on aquaculture food security. Despite inherent biases against these species, a better understanding their characteristics allows for identification those greatest concern, minimizing risk shortages infectious diseases. review summarises positive negative impacts delineating specific areas they may impact. Additionally, this gives insight expertise stakeholders would need be included if "One-Health" were implemented by policymakers control species.

Abstract Aquaculture is an important sector for ensuring global food security. Due to the scarcity of freshwater available expanding aquaculture, development omnivorous fish species and varieties that can tolerate high salinity will enhance production. Some tilapia are good candidates aquaculture in brackish seawater because they grow salinity. Among species, Oreochromis mossambicus , aureus spilurus urolepis hornorum Sarotherodon galilaeus Coptodon zillii most salinity‐tolerant. Hybrids derived from salinity‐tolerant tolerant a certain level They have been used production water full seawater. Conventional selective breeding has applied increase growth rate tilapias. However, their lower than niloticus . Recently, many genomic resources tools developed tilapia.

Abstract In Kenya, aquaculture plays a significant role in enhancing the livelihoods of rural communities by boosting local economy and diversifying protein sources. Although Vihiga County Western Kenya boasts considerable potential for aquaculture, it paradoxically experiences some highest levels poverty malnutrition country. The profitability fish farming has also been affected inefficiencies poor resources, disproportionately affecting income nutritional value who rely on Aquaculture as source cheap protein. study was conducted to assess cost–benefit production, selecting 100 farmers through stratified random sampling technique from five sub‐counties. A descriptive research design employed, data analysis using correlation regression with SPSS. Budgetary techniques were used analysis.

The global expansion of aquaculture has driven significant technological advancements, including raceways, Integrated Multitrophic Aquaculture (IMTA) and marine offshore cages. However, unregulated escapees pose a severe threat to aquatic biodiversity, acting as potential time bomb for the entire ecosystem. Addressing this issue requires comprehensive understanding impact unintentional on ecosystems, particularly in India riparian East African countries (Kenya, Uganda, Tanzania). Using an exploratory research design drawing from various peer-reviewed sources, study outlines dynamic growth these countries, identifies high-impact escape incidents, correlates risks remedies with cases, especially regions such Norway, Scotland, Ireland, Colombia, United States, where serious incidents have been reported. categorizes development trends, discusses mechanisms escapee impact, proposes remedies, assesses methods inferential strength, highlights gaps existing literature. revealed complex ecological shifts caused by invasive non-native fish species, affecting predation, competition, genetic diversity. Escaped facilities regions. escalating risk escapes was highlighted three countries. To mitigate this, integrating management into national fisheries systems, amending laws, holding farmers accountable system failure, developing regulations species within It is recommended standardize planning implement emergency plans, training, local mobilization further thresholds Ecological education communities recognition role translational scientists are crucial dissemination knowledge.

China harbors a high species diversity of freshwater fishes not shared with any its neighboring nations. Freshwater fish in the country has been under severe threat from human activities over past decades, thus conservation and ecosystems is urgently needed.
