“…Although a transcriptome of P. carnosa from Hong Kong is already available [21], its completeness is quite low, with only 73.42% complete BUSCOs (Benchmarking Universal Single-Copy Orthologs). In recent years, the health of some of these coral species has been affected by various stressors including excessive bioerosion [22–24], skeletal growth anomalies [25], bleaching [26], and recreational activities [27, 28]. To facilitate easy access to the transcriptome data, we constructed a relational database with a user-friendly Internet interface.…”

Background Scleractinian corals are important reef builders, but around the world they are under the threat of global climate change as well as local stressors. Molecular resources are critical for understanding a species’ stress responses and resilience to the changing environment, but such resources are unavailable for most scleractinian corals, especially those distributed in the South China Sea. We therefore aimed to provide transcriptome resources for 14 common species, including a few structure forming species, in the South China Sea. Description We sequenced the transcriptome of 14 species of scleractinian corals using high-throughput RNA-seq and conducted de novo assembly. For each species, we produced 7.4 to 12.0 gigabases of reads, and assembled them into 271 to 762 thousand contigs with a N50 value of 629 to 1427 bp. These contigs included 66 to 114 thousand unigenes with a predicted open reading frame, and 74.3 to 80.5% of the unigenes were functionally annotated. In the azooxanthelate species Tubastraea coccinea , 41.5% of the unigenes had at least a best-hit sequence from corals. In the other thirteen species, 20.2 to 48.9% of the annotated unigenes had best-hit sequences from corals, and 28.3 to 51.6% from symbiotic algae belonging to the family Symbiodinaceae . With these resources, we developed a transcriptome database (CoralTBase) which features online BLAST and keyword search for unigenes/functional terms through a user friendly Internet interface. Short conclusion We developed comprehensive transcriptome resources for 14 species of scleractinian corals and constructed a publicly accessible database ( www.comp.hkbu.edu.hk/~db/CoralTBase ). CoralTBase will facilitate not only functional studies using these corals to understand the molecular basis of stress responses and adaptation, but also comparative transcriptomic studies with other species of corals and more distantly related cnidarians.

“…As mentioned above, one of the measures that has been implemented by dive operators is entry points over sandy areas, away from coral reef areas [55,69]. This measure may have other associated measures as suggested by different authors, such as definition of the distances between entry points (e.g., 30 m apart, 12 m apart), maximum limit on the number of divers that can descend at each point at a time (e.g., 9 divers, 10 divers) [18,70], and minimum distances between those participating in the same activity groups [29]. There are other measures whose implementation could provide added value, like the planning of dive routes by operators so that sensitive habitats and species are not disturbed [71].…”

There are a considerable number of studies reporting the negative impacts of recreational diving and their causes, yet there is a gap in the information regarding the aspects of activity management. This paper presents a systematic approach to the management measures found in the literature. A large part of the measures identified address stakeholders’ awareness, data on the activity, and implementing adapted management measures. Stakeholders need to be integrated into the entire process of managing the activity because they are the target for correcting actions. A knowledge gap of the evaluation of the “ecological carrying capacity” of dive sites exists, along with a lack of methods for its assessment. This study informs future steps on the development of an integrated management and monitoring model that encompasses the assessment of ecological carrying capacity in further research. It also brings a vision of sustainable management of the recreational diving activity by advancing the conceptual framework of scuba diving and tourism integrated management.

“…These water activities generally take place in the eastern part of the Marine Reserve, where Hoi Ha Wan Marine Park, Tung Ping Chau Marine Park, Sharp Island, and the Ung Kong Group are the most famous traditional dive sites in Hong Kong. Specifically, these sites have relatively widespread rocky hard bottoms with more oceanic water conditions that allow the development of expansive coral ecosystems and marine species [57], which have played an important role in attracting most scuba divers [58]. Therefore, to ensure representative sampling is achieved, Hoi Ha Wan Marine Park, Tung Ping Chau Marine Park, Sharp Island, and the Ung Kong Group were the study sites to invite eligible divers to participate in facilitating the data collection.…”

The Influence of Sociodemographic Characteristics and the Experience of Recreational Divers on the Preference for Diving Sites

et al. 2022

Understanding the preferences of scuba divers is crucial for authorities to establish appropriate management plans and for service providers to offer a wide range of recreation opportunities to promote long-term industrial sustainability. This study categorized diving preferences into two subgroups (physical and biological) to explore the association between diving preferences and divers’ sociodemographic characteristics, as well as diving experiences through multiple regression analysis. Questionnaire surveys were administered, with 398 completed responses successfully collected from diving hotspots in Hong Kong. Results revealed that divers’ sociodemographic status, particularly monthly salary, could affect their physical and biological preferences. Meanwhile, divers’ diving experience was found to be a significant predictor in figuring out their biological preferences. However, no relationship between diving experience and physical preference was identified in this study. These results could inform management authorities in implementing ecological and environmental protection because biological conditions are considered the most attractive motivation for divers to dive in Hong Kong. Similarly, these results may help managers better understand divers’ recreation needs based on different sociodemographic characteristics and diving experiences to create diverse recreation opportunities while enhancing their satisfaction by avoiding the negative impacts associated with identified preference attributes.
