Choose a specific organism (animal name) and explain why it could be used of \"Catch per unit effort method\" in estimating population. Provide a practical example of that choice. Pls specific detail as much as you can in 1 page long. Thanks:)

Solution

Catch per unit effort (CPUE) is an indirect way to measure of the abundance of a species that is under target.It is mainly used fisheries and in conservation biology.A specific organism that could be used for this method is Sei whale (Balaenoptera borealis), a baleen whale. The catch per unit effort value gives a clue to either the species under target is undergoing overexploitation or under sustainable harvesting.A decreased CPUE value points overexploitation, while an unchanging CPUE value indicates sustainable harvesting.In this case,the CPUE method is used to estimate population because we can estimate the population size based on the number of whales caught by hunting per day. per.When the population of the whale decreases, the catch per day of hunting also decreases and this indicates an overexploitation.As per accurate records of sei whale harvests that have been maintained.sei whale catches showed an increase in number in the late 1950s and and was about more than 20,000 sei whales by 1964 but this number dropped to below 2000 by1976.As a result of this,in 1977 the species received IWC protection.In the Southern hemisphere where catches were initially high but in between 1965-1979, there was seen a reduction in the number of catches despite making an effort to harvest them, indicating depletion of the southern hemisphere sei whales.
