he four possible solutions relating to sustainable fishing are fish farming, fish quota, decrease in the amount of time allowed to fish, and closing marine reserves. Fish farming can be considered a possible solution because the farmers are only taking few fish from the ocean and creating hundreds more. One reason why this will not work is because the farmed fish are being fed with fish that were hunted and coming from the ocean, therefore they are still killing a significant amount of fish. Fish quota can also be considered a possible solution because it forces fisherman to limit the number of fish they take from the ocean, take fish population into consideration, and to choose their catches wisely. One reason why this will not work is because if a fisherman happens to catch more fish than they are allowed, the fisherman must throw the fish overboard. This leads to millions of pounds of fish meat being wasted each year because of this law. This system is extremely wasteful.
Another possible solution relating to sustainable fishing is to decrease the amount of time that fisherman can fish for. This might work because if fisherman aren't fishing for as much time, they won't be able to catch as many fish, therefore leaving more and more fish unharmed and still alive inside of the big, blue sea. One reason why this system will not work is since fisherman are only given a limited amount of time to fish, they will try to make their time at sea as efficient as possible, therefore they will use much more destructive equipment to catch as many fish as they possibly can. The final solution relating to sustainable fishing is to close off marine reserves. This might work because it helps the it allows the fish in that area's population to recover and then the area can be re-opened while another area is closed off because that population seems low. If this pattern continues to repeat itself, then each marine reserve should have a healthy fish population. One reason why this possibility will not work is because in theory, it is difficult to know which area to close off and for how long because you never know when a school of fish from a neighboring area is swimming by and might give officials the wrong idea.
