Historic Update IV

"The Lake's Populations Have Decreased"


About two-thirds of the fish species are now gone from the lake.  Whereas a local fisherman could once catch 20 to 50 pounds of fish per day, the catch now is a tenth of that amount.  The crab catch for the local fishermen has also declined considerably, now at one-third of former levels.  Overall, fishing as a livelihood is possible for one third as many families as before.  In the meantime, black bass weighing 10 to 20 pounds are being caught by spear-fishing tourists.

Questions

  1. What effect might the bass have on the other populations in the ecosystem?
  2. What measures could be taken to reverse this possible damage to the food chain in the lake?
