A fishprint provides a measure of a country’s fish harvestin terms of area. The unit of area used in fishprint analysisis the global hectare (gha), a unit weighted to reflect therelative ecological productivity of the area fished. Whencompared with the fishing area’s sustainable biocapacity (itsability to provide a stable supply of fish year after year,expressed in terms of yield per area), its fishprint indicateswhether the country’s annual fishing harvest is sustainable. The fishprint and biocapacity are calculated using thefollowing formulas:Fishprint in (gha) = metric tons of fish harvestedper year/productivity in metric tons per hectare ×weighting factorBiocapacity in (gha) = sustained yield of fish in metrictons per year/productivity in metric tons per hectare ×weighting factorThe following graph shows the earth’s total fishprint andbiocapacity between 1950 and 2000. Study it and answerthe following questions: If biologists determine that this country’s sustainedyield of fish is…

Now, DEC wants to change this harvest quota to maintain a stable fisher population for the next 10-years. How much would they have to change the harvest every year to achieve this goal?
Why would you not want to harvest to a point where salmon populations are kept close to K? O It would mean removing too many nutrients from the ecosystem At K, the population is not adding any additional fish so you wouldn't be able to harvest any. O Because you would be removing too many fish from the population O It would be dangerous for the fish to be at their carrying capacity

The Barton Springs salamander is an endangered species found only inthree adjacent springs in the city of Austin, Texas. There is growingconcern that a chemical spill on a nearby freeway could pollute thespring and wipe out the species. To provide a source of salamanders torepopulate the spring in the event of such a catastrophe, a proposal hasbeen made to establish a captive breeding population of the salamanderin a local zoo. You are asked to provide a plan for the establishment ofthis captive breeding population, with the goal of maintaining as muchof the genetic variation of the species as possible. What factors mightcause loss of genetic variation in the establishment of the captivepopulation? How could loss of such variation be prevented? With theassumption that only a limited number of salamanders can bemaintained in captivity, what procedures should be instituted to ensurethe long-term maintenance of as much variation as possible?
