Aquaculture: Genetics and Biotechnology
Disease Diagnostics and Therapy
Diagnostic Tests
PCR based tests
Immunology based tests: IFAT + IHC
Vaccine Development
Recombinant vaccines
DNA vaccine
E.g. ADV
Cheap and easy to produce
Temperature stable
Environmentally Sustainable Nutritional Products
Development of species-specific diets - Improving bioavailability of key components
Alternative protein sources - Development of genetically modified plants as protein source + reduce enviro pollution
Development of advanced deliver methods - Using the feed (bacteria) of the live feeds (rotifers)
Defining and Improving Genetic Stocks
Selective improvement
Domestication selection - Often causes favourable correlated response in growth and other production traits
Crossbreeding between strains for:
Disease resistance
Preferred colors
Genetic Biotechnology
Induced spawning
Selective breeding programs
Sex reversal
Transgenics
Genetic Manipulation (Genome)
E.g. Sex Reversal
All Female populations common in Salmon
Pro: year round production
Con: 90% commercial success
Triploid Production
individuals with 3 sets of chromosomes (3n)
triploids rarely out perform diploids
triploid are sterile animals
Genetic Engineering in Aquaculture
Transgenics
Transgenic Animals
Cryopreservation of gametes or gene banking - can breed off season
