Techniques for surveying exploited species
This chapter summarizes the methods available for estimating the population parameters that may be needed to assess biological sustainability, including population abundance, population and individual growth rates, rates of survival and productivity, and patterns of movement and distribution in space. The emphasis is on the need to sample populations effectively, and on understanding the strengths and weaknesses of a wide range of available survey methods. This provides a basis for selecting the most appropriate methods in a given situation, and for assessing how much effort will be required to get useable data. Extensive links are provided to detailed information on analytical methods, including software and online resources.
Keywords: sampling, survey methods, biological sustainability, population abundance, population growth rate, individual growth rate, survival rate, productivity rate
