Genetically Modified Salmon Case Study

To create genetically modified salmon the salmons' DNA is altered using genetic engineering. In the genetically engineered salmon, there are the added growth genes from the Oncorhynchus tshawytscha or more commonly known as the pacific chinook salmon, and the switch-on gene from the Zoarces americanus, or more commonly known as the ocean pout. To input these genes from the pacific chinook salmon and the ocean pout into the salmon, recombinant DNA technology is used. The scientists first identify what genes they would like to add, in this case the genes of interest are the growth gene and the switch-on gene, and isolate them. After identifying the desired genes, restriction enzymes, which cut the DNA at specific areas, are used to remove …show more content…
These added genes give the result of faster growth, increased nutrition and the need for less feed for the salmon to grow. To add these genes to the salmon, the same restriction enzymes are used on the salmon's DNA to have the correct bases for the desired DNA to attach to (Phelan, J. (2015)). The desired genes are then inserted into the genome of the salmon using the plasmid and finally added into the egg and grown like natural salmon. In my opinion, in terms of development and sale, there are more benefits than risks in introducing genetically modified salmon into the market. Many fear the sale genetically modified salmon because it is the first animals to be sold to the public as only genetically modified crop has been sold so far. There is also fear for human and environmental health. Many fear that the genetically modified salmon could cause allergic reactions because the modified salmon …show more content…
Manufacturers have the option and choice of labeling the modified salmon, meaning they could not label the modified salmon. Because labeling is not mandatory, it is not likely the manufacturers will label the genetically modified salmon as it could potentially reduce sales. Many avoid genetically modified food products and prefer organic produce even though organic products are more expensive. It would be more likely the manufacturers of organic salmon will label their natural salmon to increase prices. The labeling of genetically modified salmon should be mandatory and enforced for sale. The labels should have the names of the animal the added genes come from in case there are certain species or animals consumers are allergic to. By enforcing labeling, any negative reactions and health problems due to the genetically modified salmon could be quickly and efficiently treated. The consumer would be well informed of what they are purchasing and consuming.
