The application of genetic principles to breeding programs in order to develop desirable traits in farmed aquatic species, such as faster growth, disease resistance, and better meat quality.
Basic genetics: Understanding the concepts of genes, chromosomes, and inheritance patterns.
Breeding objectives: Designing goals for genetic improvement.
Breeding systems: Selecting the best mating methods for different species.
Heritability: Quantifying the genetic basis of desirable traits.
Genotyping: Identifying genes that control traits of interest.
Marker-assisted selection: Using genetic markers to improve breeding accuracy and efficiency.
Genomic selection: Predicting breeding values using whole-genome information.
Inbreeding and genetic diversity: Balancing selection for desired traits with maintaining genetic diversity.
Gene editing: Manipulating genetic material to develop healthier and more productive breeds.
Biotechnology: Using genetic engineering and other advanced technologies to enhance genetic improvement.
Reproductive technologies: Optimizing mating frequency, fertilization rates, and egg quality.
Parentage determination: Identifying the parents of offspring through genetic analysis.
Disease resistance: Breeding for improved resistance to common aquaculture diseases.
Growth performance: Focusing on traits that influence growth and yield.
Environmental stress tolerance: Selecting for traits that enable organisms to thrive in changing environmental conditions.
Feeding behavior and nutrient utilization: Identifying traits that enable organisms to efficiently convert feed into body mass.
Quality traits: Selecting for traits that influence the flavor, texture, and appearance of the final product.
Ethics: Understanding the ethical implications of genetic manipulation and breeding.
Crossbreeding: A method in which two different species or breeds are mated in order to produce offspring with desired traits.
Inbreeding: A method in which closely related individuals are mated in order to enhance desirable traits or to produce pure-bred lines.
Outbreeding: A method in which two different breeds or lineages are mated in order to introduce new genetic traits or to improve the overall genetic diversity.
Hybridization: A method in which two different species or subspecies are intentionally crossed in order to produce offspring with desirable traits.
Selective breeding: A method in which only the best breeding candidates are chosen for mating, based on certain criteria such as desired traits or performance.
Genetic modification: A method in which the DNA of an organism is artificially altered in order to introduce new genetic traits or to improve the expression of desirable traits.
Genome sequencing: A method in which the complete DNA sequence of an organism is determined, usually for the purpose of identifying specific genes associated with desirable traits.
Marker-assisted breeding: A method in which molecular markers are used to identify and breed individuals with desirable or undesirable traits.
Multiplication breeding: A method in which a superior strain or variety is repeatedly mated to produce a large population of high-quality offspring.
Gene editing: A method in which specific segments of DNA are cut and replaced or modified in order to introduce new genetic traits or to enhance the expression of desirable traits.
