The Increasing Demand For Fish On The Food Industry

Good Essays

The increasing demand for fish in the food industry has resulted in extensive overfishing in wild fisheries. This has caused widespread habitat destruction, overfishing, and an overall loss of biodiversity with both freshwater and marine ecosystems. To compensate for the issues surrounding industrial overfishing of wild populations, farmed fisheries in sheltered coastal waters, rivers, ponds and tanks were introduced. The innovation of genetically modified (GM) farmed-raised fish which possess traits such as larger mass, faster growth, and increased resistance to diseases may alleviate the industrial pressure from the food industry for consumer relevant species. However, developing a transgenic GM fish does present a risk to wild …show more content…

Research trials on aquaculture species are both time-consuming and costly. The use of zebrafish (Danio rerio) as a model organism is quickly gaining a reliable reputation in aquaculture research as it resolves these disadvantages. The sequenced genome of zebrafish also offers a huge advantage by allowing the use of technologies for molecular analysis such as genotyping. Zebrafish has proven itself to be a representative system in understandings biological characteristics of a larger group of organisms. For these reasons, we use zebrafish in this study to explore a transgenic approach for biological confinement. 1.2. Bioconfinement The introduction of GMOs in the food industry has provided some relief on the population demand for food. However, this comes with the concern of possible release or escape of transgenic species into the wild and the effects that this would have on natural environment. The two primary methods of biological confinement are physical and genetic confinement. Physical confinement include the use of barriers to prevent escape within an environment. In aquaculture, this can involve the use of the conventional net pen systems or land-based facilities. However, this confinement method has inherent risks which cannot ensure restraint on the proliferation of GMO’s in the event of escape into the wild. Genetic control can include methods such as dependence factors only available through supplementation within an
