An iterative model to construct an age-length key to assess the age composition of a new fishery for Dissostichus eleginoides in Chilean waters
Abstract: Traditional calculation of catch age composition estimate requires that the age-length ... data and random length frecuency be sampled from the same population, in other case an age-length key ... is capable of providing biased estimates of age distribution. By using the iteration algorithm is ... possible to overcome this limitation. The catch age composition for Dissostichus eleginoides was obteined ...
