Aquaculture originates from ancient Chinese wisdom, and is considered the most efficient food-producing industry. About 70 years ago, New China proposed an industrial approach to fish production made a policy decision begin modern aquaculture development. As one of lucky persons since early 1980s, I have committed my scholarly career studies on genetics breeding biotechnology polyploid gibel carp (Carassius gibelio). Here, several significant recent innovations, such as proposition amphitriploid concept, association ploidy changes with reproduction transition, finding unique ameio-fusiongenesis mode, establishment controllable fertility approach, creation intermuscular bone-free mutants, well recreation desirable goldfish, are introduced emphasized active participant these innovations. Additionally, some innovations contributions also highlighted in other aspects including feed development, disease control, facilities equipment upgrading, paradigm mode changes. This comprehensive synthesis wisdom seeks provide valuable insights into field historical basis.

Nile tilapia (Oreochromis niloticus) aquaculture continues to significantly contribute the growth of sector in Uganda. However, its production is beset by erratic and unreliable seed supply. Also, most hatcheries practice inbreeding broodstock, resulting inferior characterized low rates. As such, a selective breeding program necessary readily avail fast-growing that respond farmers' needs. The present review consolidates available information on developing article discusses significance genetic improvement, drawing lessons from successful programs other countries. From literature review, no systematic was traceable Scanty efforts species available, with little evidence selection for improved performance.

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. Urgent government action needed address unreported escapes, preventing ecosystem degradation ensuring sustainability.

This chapter explores the applications of population genetics in genetic improvement and biodiversity conservation fish species. It traces evolution genetics, from earliest measurements variation at allozyme loci to current era genomics, highlighting technological advances that have revolutionized field. The emphasizes importance understanding both historical recent processes shaped patterns diversity, particularly face declines driven by anthropogenic activities climate change. Various molecular techniques used assess diversity are analyzed, including traditional markers such as allozymes DNA-based markers, amplified fragment length polymorphisms (AFLP), mitochondrial DNA (mtDNA), microsatellites. We discuss advantages disadvantages each method, emphasizing their application structure analysis, gene flow assessment, reproductive strategy studies. Additionally, addresses use these marker-assisted selection enhance productive traits commercially important primary objective is highlight how concepts, flow, drift, natural selection, can be applied improve Furthermore, for health sustainability aquatic populations, captivity wild, underscored.

This study presents a case focused on sustainable farming practices, specifically the cultivation of tilapia (Mozambican and aureus species) in ponds with geothermal water. research aims to optimize hydrochemical regime experimental enhance growth metrics external characteristics breeders. The dataset encompasses parameters fish feeding base from where were cultivated. Genetic algorithms (GA) employed for hyperparameter optimization (HPO) deep neural networks (DNN) prediction productivity each pond under varying conditions, achieving an R2 score 0.94. GA-driven HPO process is robust method optimizing aquaculture practices by accurately predicting how different conditions feed bases influence tilapia. By determining these factors, model promotes improving breeding outcomes maximizing aquaculture. approach can also be applied other systems, enhancing efficiency sustainability across various species.

Abstract The African catfish ( Clarias gariepinus ) is a commercially important species, for both fisheries and aquaculture, now the most commonly farmed fish in sub-Saharan Africa. However, knowledge about genetic diversity population structure of wild populations, which crucial effective conservation sustainable aquaculture management, scarce. Using mitochondrial DNA (mtDNA) cytochrome c oxidase 1 gene (COI) sequencing genomic analysis using triple restriction site-associated (3RAD), we investigated C. populations from Nigeria, including an albino form found wild. Eleven COI haplotypes were identified, seven unique to samples. Wild sampling sites had slightly broader range higher maximum values observed heterozygosity Ho = 0.109 – 0.165), expected He 0.111 0.216), nucleotide pi 0.125 0.225) compared 0.118 0.147, 0.112-0.144, 0.117 0.151). Conversely, differentiation Fst was among ones there high between 0.31 0.47). Despite evidence admixture fish, little two groups. Nevertheless, mtDNA 3RAD data strongly suggested that collected wild, fact farm escapees. overall genotypes suggesting integrity has been maintained, this escape provides warning potential risks increasing activities. Specifically, indicates need greater regulation farms monitor reduce risk escapes.
