4 FISH/INVERTEBRATE AND CORAL SURVEY OVERVIEW Survey dates: April 8-19, 2002 Data observed and recorded by: Marjo van den Bulck and Maryke Kolenousky WATER TEMPERATURE & VISIBILITY There were several daily rain showers during the monitoring period, which is unusual for April. Cloud cover was moderate to heavy on most days. Water temperature was 26C during the monitoring period, which is two (2) degrees cooler than the January monitoring period. Visibility varied from less than 15m to over 30m. As compared to the January monitoring period, when little to no current was recorded, there was a moderate to strong current running from west to east (the reverse direction the current normally runs) during the whole monitoring period. Shallow-water surge was also extraordinarily stong. TRANSECTS Three (3) transect lines 95m long were set up for the coral line and fish/invertebrate belt surveys. Each line was divided into four 20m sections with 5m intervals, in accordance with accepted monitoring practices. Transect numbers 1 and 2 are on the west side of the bay at depths of 12m and 6m respectively. Transect 3 is on the east side of the bay at 10m. Coral monitoring was carried out over each 20m section with sampling points at.5m intervals. Fish/invertebrate monitoring was done over a contiguous 5m-wide belt along 20m sections of the above described transect lines. Detailed transect setup information can be found in the PortoMarea Marine Monitoring Manual. overview Sheet 3 3

5 CORAL MONITORING Health The overall general condition of the reef reflects the damage sustained in 1999 from Hurricane Lenny. Large boulder corals were overturned, and the corals subsequently died off. Transects 1 and 2, on the west side of the bay exhibit some regeneration, e.g. new maze and mustard hill corals have begun to grow on the old dead coral boulders. Transect 1 had a high Y Algae count, observed mainly on the old dead boulders. Macro Y algae was observed on Transects 2 and 3. Transect 2 is basically a shallow patch reef, and the high percentage of sand cover reflects the spaces between coral patches. One case of Yellow Blotch disease was observed on a star coral on Transect 1. Damage Signs of recent damage,e.g. broken hard corals, were recorded along Transect 1. It is assumed that this damage is attributable to divers. FISH/INVERTEBRATE SURVEY Approximately 35% less fish were recorded along Transect #3 (10m depth) on the east side of the bay as compared to Transect #1 (12m depth) on the west side. Significantly fewer tube worms were observed along Transect 3. Many more hamlets were observed during this monitoring period as compared to January. Cherubfish were observed for the first time on the transects. Large schools of juvenile striped grunts were observed for the first time on Transect 1. Schoolmasters increased by 300%. Most of those observed were small ones in large aggregations. Numbers of parrotfish have increased by 24%. overview Sheet 4 4

6 REEF BALL CLUSTERS There are 2 snorkel trails laid out, consisting of 10 reef ball clusters on the west side of the bay at depths ranging from 1.2 to 3.8m, and 12 clusters on the east side of the bay at depths from 1.5 to 4.3m. On April 6, 2002, 6 additional reef ball clusters (approximately 100 balls) were placed on the east side of the bay along the top edge of the inner reef, at an average of depth 4.3m. This brings the total number of clusters to 18. With the exception of the new Clusters, all the Reef Balls have begun to show heavy algae growth. In the case of Cluster 10R, the algae is beginning to overgrow the coral plugs. CORAL PLUGS On February 8, 2002, six (6) varied coral plugs, incorporating a new transplant method, were planted on Cluster 12L. Twenty-four (24) Staghorn coral plugs were planted on Cluster 12L on March 23, These new plugs have been included in the report. On the right side, Cluster 10R, the coral plugs are showing signs of stress. Several are covered in heavy algae growth. Conversely, the staghorn plugs are showing new growth at the plug bases and vertically with an increase in the number of branches. FISH/INVERTEBRATE SURVEY - OBSERVATIONS Many juvenile princess parrotfish were observed on the reef ball clusters, as well as large schools of juvenile brown chromis. overview Sheet 5 5
