Our analysis of production and cost begins with a period economists call the short. run. Theshort run in this microeconomic context is a planning period over which the. managers of a firm must consider one or more of their factors of production as fixed.
Sharks have two sets of paired fins on the sides of their body, in the same general position as the main wings and horizontal tail wings of a plane. The shark can position these fins at different angles, changing the path of the water moving around them.
Shark finning refers to the removal of fins from sharks, often while the shark is alive. The sharks are sometimes discarded back to the ocean, still alive but without their fins.[1][2][3] Unable to swim effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators.
