Fish survey method 250m 2 survey area 5m width 50m length O1 O2 16 black are counted, white not counted
O2 O1 tape measure Step by step fish survey method 1. Two observers (marked O1 and O2) select any starting point on the reef. They then measure 2.5m either side of this point with the tape measure to line up the edge of the 5m width of the transect. O2 securely ties the end of the tape measure to the reef. 2. O1, the fish recorder, then begins swimming in a straight line from this start point and records the numbers and estimates the size of key fish species observed within a 5m width. The transect line should go over areas with rock and coral, not large areas of seagrass and sand, and parallel to the shore. 3. O2 swims just behind O1 laying out the 50m tape measure. O2 lets O1 know when the 50m point is reached to stop the fish count. The tape measure is then left on the sea bed and held down by a weight. TIPS: Swimming should be slow but at a regular speed, taking around 10 minutes to cover the 50m line. Once the end of the 50m transect is reached, O1 and O2 switch to recording macro-invertebrates, returning back along the transect. This process is repeated on six separate transects in a site. 17
