Fishing Lab
Data Table:
Questions:
- There are eight people fishing now.
- The increase in people fishing has increased the number of fish caught and decreased the number of fish left in the bowl.
- We replaced some fish back in the bowl after the fishing season because there needs to be enough fish to reproduce and create more fish by the time the next fishing season comes along.
- You couldn't have more than 16 fish in the bowl at a time because 16 fish was the capacity of the ecosystem. The ecosystem could not hold and comfortably house more than 16 fish and if more fish of the same species came, then there would be intra specific competition.
- If a group took too many fish out of the ocean in one season, there would not be many fish to reproduce and keep that ecosystem going. If the group did not leave any fish, the population would go extinct in that area and ecosystem's food chain/food web would become distorted.
- This simulation represented a small part of the ocean and its changes over a few years. The simulation has a bowl that represents the ocean and an artificial reef and the 16 goldfish represent the capacity of the fish that the ecosystem could hold. Over fishing is a major problem in artificial reefs. Multiples of fish thrive in artificial reefs and fishermen are attracted to the reefs and they tend to fish a lot for profit, but often don't throw back some fish to reproduce for the next fishing season. Soon there are no fish in that artificial reef.
