Abstract:
The Orange Keyhole Sponge, Mycale armata Thiele, was unknown in Hawaii prior to 1996. First reported in Pearl Harbor, it now occurs in virtually every commercial harbor in the main Hawaiian islands, where it can be a major component of the fouling community on harbor piers and jetties. It has been reported from a few coral reef locations near harbors, but in Kaneohe Bay it has become a major component of the benthic biota in the south bay in the last 5-10 years. A study was conducted in 2004-2005 to determine Mycale armata's distribution, abundance throughout the bay, its growth rates on permanent quadrats, and whether mechanical removal would be an effective management technique for its control. Results from 190 manta board surveys on 28 reefs and paired 25 m belt transects using photo quadrats on 19 reefs indicated that the sponge had maximal coverage in the south-central part of the bay, in the vicinity of Coconut Island.
Purpose:
To determine Mycale armata's distribution, abundance throughout the bay, its growth rates on permanent quadrats, and whether mechanical removal would be an effective management technique for its control.

Process_Description:
1. Manta Board Surveys Manta board surveys were conducted in Kaneohe Bay in September 2004 to determine the extent of occurrence and relative coverage of Mycale armata. The Global Coral Reef Monitoring Network's (GCRMN) manta board procedure described in the Methods for Ecological Monitoring of Coral Reefs, (<http://www.icran.org/pdf/Methods_Ecological_Monitoring.pdf>), in which a trained observer is towed for two minutes behind a small boat, was modified to a snorkeling observer swimming with the manta board for four minutes along the reef edge. This modification was found to be more feasible in Kaneohe Bay because of the difficulty in towing behind a boat under the prevailing wind conditions and the general murkiness of the water in the bay. The manta board swims were a satisfactory and time-efficient method for rapidly acquiring a substantial quantity of semi-quantitative distribution data for dominant benthic organisms. The observer estimated and recorded the coverage of Mycale armata, the two dominant corals Porites compressa and Montipora capitata, the introduced feather duster worm Sabellastarte spectabilis and the invasive algae Dictyosphaeria cavernosa, Gracilaria salicornia, and Kappaphycus sp. on reef crests and slopes along the edges of reefs in the south and middle sectors of Kaneohe Bay. The relative abundance of each these species was estimated and recorded using the GCRMN scale ranging from 1 (1-10% cover) to 5 (75-100% cover). The location of the beginning and end of each swim was recorded using a Garmin 76 WAAF Global Positioning System (GPS) unit accurate to &#177; 8 m carried by the manta board observer in a waterproof bag. Using this technique the 190 manta board transects shown in Figure 1 were completed on 28 reefs by three observers in 13 days.

2. Quantitative Photo Quadrat Transects Having established the extent of the sponge in the bay using manta board swims, linear photo transects were used to establish quantitatively the areal coverage of Mycale armata and other dominant benthic biota along transects at 19 sites on 18 reefs throughout Kaneohe Bay. Digital photographs of bottom cover were taken along belt transects using an Olympus 5060 digital camera contained within an underwater housing and held on a fixed height camera stand, producing an image area of ca. 0.66 m2. Twenty-five photographs were taken on each of two transects per site for a total of 33 m2 reef surface measured per site. The start and end of each set of transects was recorded using GPS and mapped using ArcGIS.

Images obtained were enhanced and cropped to a consistent size of 0.66 m2 and processed using the Coral Point Count with Excel extension (CPCe) program available from the National Coral Reef Initiative (<http://www.nova.edu/ncri/research/a10.html>). Each quadrat was assigned 50 random points and the composition under each point was recorded, for a total of 1250 points analyzed per transect or 2500 points per site. These data were used to determine the percent cover of Mycale armata, macroalgae, corals and other invertebrates, and substratum types within the photoquadrats, which were averaged at each site.

3. Measurement of changes in sponge cover on control and removal quadrats

Twenty permanently marked photo quadrats were established in October 2004 on the reef slope along the southeast perimeter of Coconut Island to monitor sponge growth and competition with reef corals within the marked areas. The corners of each 0.165 m2 quadrat were marked with iron rebar or cable ties, enabling quarterly measurements of the same reef area for each quadrat throughout the year. No sponge was removed from 10 of the quadrats (Controls), while all the sponge that could be mechanically extracted from the remaining 10 quadrats (Removals) was removed. The amount of sponge removed averaged an equivalent of 1.85 kg dry wt per m2 for the ten quadrats. This was time-consuming and impacted corals within some of the quadrats, requiring an equivalent of 12.6-22.7 hr/ m2 for removal from a single quadrat and removing an equivalent 0.18-1.72 kg m2 of live coral skeleton as by-catch from six of the ten removal quadrats. Both sets of quadrats were photographed soon after sponge removal and quarterly thereafter in February, May, August, and November 2005 using a digital camera on a stand with a fixed photographic area of ca. 0.165 m2 .

After cropping to a consistent image area of 0.165 m2, the CPCe program was used to analyze the coverage of all components within the permanent photo quadrates for each quarter's determinations in a similar manner as was done for transect photo quadrats, except that 100 points evenly spaced in a grid were used for analysis of each permanent photo quadrat. This stratified approach provided greater sensitivity and probability that the same specific areas on a quadrat were being sampled each quarter, resulting in more replicability for time-series analyses of changes within the permanent photo quadrats.

4. Measurement of changes in weight and volume of sponge fragments

Twenty fragments of sponge were collected from near the HIMB pier on 3 December 2004, transferred to the laboratory, and held in flowing seawater under screen shade until 6 December. They were then photographed underwater with the digital camera held on a small quadrapod frame that provided a consistent image frame size of 412 cm2 . The sponges were then weighed underwater in a basket suspended from the bottom hook of an Ohaus Scout-Pro digital balance read to 0.001 g. Each sponge fragment was weighed twice and the results averaged. After weighing and photographing, each sponge was placed on a piece of underwater paper and both sponge and paper were attached to galvanized wire mesh platforms and deployed to the reef where they were held in place by cable ties attached to quadrat marker stakes or coral branches. The sponges were photographed and weighed quarterly thereafter in March, June, September, and December 2005. The projected areas of sponge images were determined using CPCe analysis software for determining the area of a irregular object. Duplicate area determinations were made and averaged for each sponge at each quarterly measurement. Coles, S.L. and H.Bolick, 2006.
