Because they are manmade, fish farms are not considered fisheries

Fish farms are not considered fisheries because they are manmade. They are considered unnatural because they are  made either by excavation or building a dam allowing water to build up.

Fish farms are easier to manage because there are fewer species of fish and they are smaller and simpler.

This metaphor uses symbolism when describing the “arch” of ulysses life. he is trapped in a time of life where adventure is moving as he tries to proceed to it. he will never reach it and will learn to accept it. ulysses symbolizes that arch in life, that no one can reach every goal, or every sight in life. even though this personality of curiosity and purposefulness exist in all mankind, the purpose of showing his strive to succeed symbolizes great leaders today. his curiosity represents the curiosity of humans that everyone desires to find answers and wont give up without a fight. ulysses is a symbol of the human race.
