Marine Science Resource Essay

Specifically, which are a top rank predator. Killing these animals in this way prevents us from being able to harvest them and can change the ecosystem depending on the fish. The next destructive is the Stern Trawling. This is destructive due to the method of capture, in the sea for long periods of time. While this might seem beneficial as it can catch more fish, it may catch sea mammals or endangered creatures that aren’t intended for capture. It has a low accuracy of the specific creature to be caught and less time to save from the possible entanglements due to the length of time in the water.Activity- Part 3 Beach major impacts the environment as it catches large populations of already over-fished species, without great accuracy.

There are numbers even as much as 90% of the catch is thrown back because they are either not the right fish or they are undersized. Catching undersized fish negatively affects the population because they are not suitable to be sold, and are thrown back dead or dying. Long Lines are a configuration of shorter lines attached to one another to create one “long line”.Having thousands of hooks at a time in the open ocean causes many other marine animals, such as sharks, dolphins, and even birds, to get caught and. Also, the wrong species of fish can get caught, which creates a loss of time and production. FADS are large nets that catch fish when there are enough in the area. Their catch can be up to 80% beach, which negatively affects the populations of already endangered and overfilled species.

The removals of these FADS are necessary due to their low accuracy in a catch and destructive nature to the marine ecosystem.Fisheries are declining because of this said destruction, as other destructive fishing practices like bottom trawling, can destroy 1/5 of the sea floor fauna and flora at a time, and also because of large equipment that processes ,dos of tons a fish in a year, such as super trawlers owned by American Seafood. Environmentalists such as Poor management practices are taking place in fishing, as many fishers refuse to add any devices unless they are necessary.Practices such as adding turtle exclusion devices, bird-scaring devices, and dolphin- scaring devices help in reducing the amount of beach in a fishing device, however better regulation, bans, and marine reserves will better improve the declining population of overfilled species.

Activity- Part 4 believe that the marine reserves would be best to help restore the oceans room the destruction that has happened in the past and is currently going on.The marine ecosystem is one of the most influential and diverse ecosystems we have on our planet, so we need to shield it from any more negative activity to better our own lives. Having protected and safe areas where the marine life can restore themselves from human demolition will affect the areas that are losing population because the fish will travel around. Also, allowing humans go there to interact harmlessly will help heighten their appreciation for marine life, therefore influencing human decisions.
