At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die. 2.
