This video is a part of Conservation Strategy Fund's collection of environmental economic lessons and was made possible thanks to the support of the Gordon and Betty Moore Foundation and the Marcia Brady Tucker Foundation. This series is for individuals who want to learn - or review - the basic economics of conservation. This video covers maximum economic yield in fishing and fishing quotas. We'll compare growth rates and fish populations and look at where on the growth curve the population reaches sustainability. We'll also introduce the concepts of fishing effort, economic rent and maximum sustainable yields.
