ARTICLE INFO Article History: Received: 9/3/21 Accepted: 19/4/21 Published: 31 Dec 21   Tunku Abdul Rahman Park (TARP) is a Marine Protected Area (MPA) and a famous tourist destination in Sabah. The possible long-term negative impacts on the ecology and sustainability of the Park due to the very high number of tourists is of much concern to the Park management authority. This study was conducted to determine the ecological and tourism carrying capacity in three islands in TARP, Manukan, Mamutik and Sapi islands. The Effective Carrying Capacity (ECC) concept is applied in this study, in which the results are expected to provide the Park Authority with data and effective management actions. Calculation of carrying capacity in this study was based on three distinct visiting patterns or seasons: i) Regular season; ii) High season, and iii) Festive season in order to ensure optimal tourists' satisfaction and revenue, while still maintaining ecological sustainability. ECC was calculated after considering the various limitations imposed by physical, climate, ecological, and management capabilities. Land and ocean areas were considered and calculated separately as they occupied different variables. Our findings showed that Manukan island recorded the highest ECC, while Mamutik and Sapi island shared almost similar ECC value. Optimization of Carrying Capacity (CC) in different seasons was also achieved with a few Correction Factor (CF) adjustments. It shows that Festive season recorded the highest ECC, followed by High Season and Regular Season. The ECC obtained was suggested to be implemented to TARP management as to preserve and sustain the ecological value of the Park.

The Darvel Bay is a large semi-enclosed bay with spectacular natural land and seascape. The inward side of the Bay has only been recently known to be an important foraging ground for the endangered, threatened and protected (ETP) elasmobranch species, such as the Whale Shark and mobulid rays. Following a recent scientific expedition, we present a checklist of the coral reef fishes of Darvel Bay. A note on the biodiversity and community structure is presented, based on our analysis using diversity indices, univariate and multivariate approaches. Seven natural coral reefs comprising two fringing reefs and five patch reefs, were surveyed at 10 m depth using underwater visual census (UVC) and baited remote underwater video station (BRUVS) methods. A diverse list of 66 species of reef fishes from 17 families is recorded. However, this is overwhelmingly dominated by the small-sized omnivorous damselfish, family Pomacentridae (62%; N = 1485 individuals). Species richness and abundance were observed to increase at sites surveyed furthest from the coast within the Bay. Significantly distinct reef fish assemblages were observed between three priori groups, based on proximity to shore (ANOSIM, R = 0.65, p < 0.05). SIMPER analysis further revealed that 22 species of the total reef fish species recorded drive 76% dissimilarities between the groups. The pattern of the reef fish communities observed, reflected as a logseries distribution model, is that commonly found in disturbed habitats or habitats characterised by restricted resources in a community, where the dominant species takes up a high proportion of available resources. The ecological indices (Shannon-Wiener Diversity Index, 2.05; Simpson Index of Diversity, 0.79; Simpson Dominance Index, 0.20; and Pielou’s Evenness Index, 0.43), all reflect the relatively low diversity and uneven species distribution of the reef fish community. We conclude that the present status of the coral reef fish community dominating Darvel Bay as having undergone a rapid shift in structure following intense and rampant fishing pressure, as reported by the media.

Tunku Abdul Rahman Park (TARP) is the first Marine Protected Area gazetted in Sabah, Malaysia in 1974. It is also one of the most famous tourist destinations in Sabah which experiences a high anthropogenic disturbance that could create major damage in the long run if not properly managed. TARP has been flooded by tourists receiving more than 500,000  tourists in 2018 and 2019. It is clear that tourism activity in TARP is one of the major contributions to anthropogenic disturbance. Therefore, it is essential for tourists to have a high level of awareness to conduct sustainable and eco-friendly tourism activity. In this study, we assessed the level of awareness and knowledge of the marine environment among tourists in TARP. Briefings by tour guides or companies were also assessed. Overall, results showed a low awareness level among tourists in TARP. This is somehow related to the fact that the briefing score by tour companies was low and only focused on promoting their company. TARP authority should implement a standard 5-minute video on the marine environment and assign more signage on the island in an effort to raise awareness among tourists.
