Sustainability and Cost
Cod is a popular seafood that is consumed widely across the world. However, overfishing has caused a decline in cod populations, and as a result, cod has been classified as an endangered species in some regions.
Wild-caught cod is generally more expensive than farm-raised cod, but it is more sustainable because it is caught using sustainable fishing methods.
Sustainable fishing methods ensure that the cod population is not depleted and that the ecosystem is not damaged.
Sustainability of Flounder
Flounder is a flatfish that is similar to cod in taste and texture. Like cod, flounder is also affected by overfishing, and as a result, some species of flounder are endangered.
Wild-caught flounder is generally more sustainable than farm-raised flounder. However, it is important to note that not all wild-caught flounder is sustainable.
Flounder caught using unsustainable fishing methods can damage the ecosystem and deplete the flounder population.
Cost
The cost of cod and flounder can vary depending on several factors, including the season, location, and availability.
Generally, wild-caught fish is more expensive than farm-raised fish. Farm-raised fish can be produced at a lower cost because they are raised in controlled environments, and the risk of disease is lower.
However, farm-raised fish are often fed antibiotics to prevent disease, which can lead to antibiotic resistance in humans.
