There are many factors that contribute to the profitability and unprofitably of the seafood industry every year but overtime the weaker businesses go out of business and the stronger ones start to thrive and you reach a point where the industry is able to sustain itself with profitability all around.
The seafood industry will be sustainable. Approximately three billion people in the world rely on both wild-caught and farmed seafood as their primary source of protein. The United Nations Food and Agricultural Organization estimates that eighty-five percent of marine fish stocks are either fully exploited or over fished. Similarly, many fisheries throughout the world throw away more fish than they keep. This incidental catch of non-target species—known as by catch—is harmful to many species.
The seafood industry can be sustainable if consumers broaden the scope of sea animals it consumes. Two-thirds of the earth is covered in water, much of which is salt water. The limited types of seafood consumed by the general public and the high demand for very specific types of seafood creates shortages that disrupt eco-systems and make the seafood industry unsustainable. If a wider array of seafood was consumed on a more balanced level, then eco-systems could balance themselves.
I think the best route for the seafood industry is to have more fish farms and hatcheries. We are going to eventually fish the lakes, rivers, and oceans out if we continue relying on seafood. Especially as the world's population continues to boom. There must be other ways to do this.
I don't think the seafood industry will ever be sustainable. There are multiple issues affecting the industry. Many areas off the coasts have been severely over fished and there are fears some species may die out. In spite of government warnings, over fishing still occurs. Oil spills and pollutants have contaminated our waters and are taking a toll on our coral reefs and the fish that live among them.
