 One of the simplest methods for identifying a troubled fishery is to compare the average size of mature stock over a period of time.In the case of hake, another popular catch off the cost of Chile, the median length for mature stock has shrunk from 37 centimeters a decade ago to 28 centimeters today.Efforts have been made to block the “Fisheries Act” through petitions to the Constitutional Court sponsored by a number of Congress representatives, but these efforts have yet to see progress.
