The CMSU Coral Reef Fish Count Project

St. Ann's Bay, Jamaica - June, 1999

I. Description: Two locations were compared, Lee Reef and Drax Hall.
 
The Lee Reef habitat of St. Ann's Bay (shown below) is very open (far from shore) and the water is extremely species rich. The coral structure provides for more habitat niches, and its wave action renews the plankton population. Among other things, fish traps are commonly found here. Although in this photo all you can see is the water surface, Lee Reef is very structured by the coral (see photo on the right).
 
 
Drax Hall (shown below) is very protected and less structured than the reef. There you would find turtle grass beds, mixing of freshwater from streams, and a closer shore.

II. Hypotheses:

III. Problems of the Investigation:

IV. Procedure: The five teams (of four individuals) each counted the first 100 fish seen at each location. Each team had one individual recording data on an underwater slate while the three other members identified the fish seen using waterproof fish guides.

VI. Analysis of Data: Now it is your turn! First print each of the two tables above. To make it easier to print these tables, you can open them in their own browser windows. Here is the Lee Reef data table and the Drax Hall data table.

Next, complete the "total" and "%" columns in each table. Use your math and graphing skills to present the data in an organized way that shows some method of statistical or descriptive analysis. Here are some suggestions and examples of how to display this data.

Finally, use the data to write a conclusion that supports or rejects one or more of the hypotheses from section II.
