Seamounts
The reading describes seamounts. First, seamounts have great biodiversity, because of currents that flow up from the ocean floor and bring life-sustaining nutrients. Moreover, because of the nutrient rich waters around seamounts, a great variety of plants and fish make seamounts their home. Some of these fish are found only around seamounts. In addition, seamounts attract commercial fishing.
The lecturer elaborates the description of commercial fishing industry. First, the lecturer argues that a fish from New Zealand named Orange Ruphie lives in seamounts. It is deemed to be impossible to fish them, so commercial fishing industry uses destructive methods to catch this fish in seamounts. They use a destructive way of fishing called bottom trolling that destroys ocean floor and catches other fish besides Orange Ruphie. Second, Armorheads, another kind of fish, live in seamounts. They were eliminated by Russians and still need time to recover.
