Aquaculture Transgenic Fishes Questions and
Answers
1: What is a transgenic fish? - correct answer -
A transgenic fish is a fish that has had its genome altered through the
introduction of foreign DNA to exhibit new traits or characteristics.
2: Why are transgenic fishes created in aquaculture? - correct answer -
Transgenic fishes are created to improve traits such as growth rate, disease
resistance, and environmental tolerance, enhancing productivity and
sustainability in aquaculture.
3: What is the most common method used to create transgenic fishes? -
correct answer - The most common method is microinjection, where foreign
DNA is injected directly into the fertilized egg of the fish.
4: Which species of fish have been most frequently modified transgenically?
- correct answer - Commonly modified species include Atlantic salmon,
tilapia, and zebrafish.
5: What is the primary benefit of transgenic fish in aquaculture? - correct
answer -
The primary benefit is increased growth rate, which can lead to faster
production cycles and higher yields.
, 6: How does the AquAdvantage salmon differ from wild-type salmon? -
correct answer -
The AquAdvantage salmon contains a growth hormone gene from Chinook
salmon and a promoter from the ocean pout, enabling it to grow year-round
and reach market size faster.
7: Are transgenic fishes safe for human consumption? - correct answer -
Regulatory bodies like the FDA have deemed certain transgenic fishes, such
as the AquAdvantage salmon, safe for human consumption after thorough
evaluation.
8: What are the potential environmental risks of transgenic fishes? - correct
answer -
Potential risks include the possibility of transgenic fishes escaping into the
wild, outcompeting native species, and disrupting ecosystems.
9: How can the escape of transgenic fishes into the wild be prevented? -
correct answer - Measures include physical containment systems,
sterilization of transgenic fish, and geographic isolation of aquaculture
facilities.
10: What is gene silencing in the context of transgenic fishes? - correct
answer -
