Area A Assessment: Area B Assessment: Area C Assessment: The fishers you are working with decided to close off The Isleta, a small island with a perimeter of 1.4 km near Ancón. So far they have closed it to fishing for 5 months. During this time, you’ve worked with the divers to collect scientific data on the CPUE for Black Rock Snail. Here the CPUE is measured in kilograms of snails collected during a 10 minute dive. Based on the graph below, describe the effect of the closure on CPUE. Now that you have these data, what more do you need to know? Will you continue the closure? For how long? Do you feel that 5 months of investigation is long enough to understand all of the factors involved in the population dynamics of the snail? What further investigations might you propose in order to develop a management strategy for the Black Rock Snail in this area?
