Available in PDF, EPUB and Kindle. Book excerpt: Hong Kong provides a marginal marine environment for coral growth due to its high latitude in addition to massive freshwater run-off from the Pearl River Delta. Previous studies have reported that Hong Kong waters nurture 84 species of scleractinian corals in 28 families distributed in various locations, especially the protected bays in the eastern waters. However, very little is known about the benthic composition and health of coral communities. This study aimed to 1) determine the benthic composition of local coral communities and understand the environmental determinants of coral coverage and coral community composition; 2) record coral colony size frequency distribution across these 33 sites to understand the patterns of coral recruitment in recent years; 3) quantify coral bioerosion and corallivory by the long-spined sea urchin and explore the feasibility of remediating the coral damage by a coral-associated portunid crab. Surveys were conducted at 33 sites in Hong Kong, which cover sites with the highest coral coverages that are mainly located in the north-eastern, east and south-eastern waters. A belt-transect photo quadrant method was applied. 22 hard coral genera were identified, among which the genera Porites, Platygyra and Pavona were found to be the most abundant. Most of the study sites were dominated by few genera of massive corals which led to a low diversity. Coral coverage was negatively associated with nutrient levels including nitrogen, phosphorus and organic matter deposition rates based on sediment trap data. Apart from sedimentary parameters, coral coverage was also found to be strongly negatively correlated with the density of the long-spined sea urchin Diadema setosum. Study sites were categorized into four different conservation classes with sites of higher diversity assigned a higher conservation value. These data could serve as a baseline for measuring changes in benthic composition in the future, and as a reference for management planning such as designating new marine parks. Determining the size structure can help predict how a population may change in the future and whether conservation efforts are effective in promoting the increase in numbers of individuals. To determine coral size structure in local waters, a video transect method was adopted to capture videos on the benthic substrates of the 33 study sites. In the laboratory, the video clips were analyzed to extract information on the size and growth form of all coral colonies along the transects. Size-frequency distribution plots generally showed a highly positive skewness, which indicated a dominance of small-sized (i.e. 10 - 30 cm) colonies, yet low in recruitment-sized (i.e. 5 cm) colonies. An examination of the size distribution of the most common genera showed that the distribution patterns were more genus-dependent rather than site-dependent. Also, massive corals were the most dominant growth form, while branching corals were the least common which was different from healthy tropical reefs. Apart from establishing a baseline of coral communities, coral bioerosion was further studied. Previous studies found that coral coverage and urchin density were negatively correlated in local waters. Further, severe coral bioerosion had been reported to cause community-level coral damage in several locations. Therefore, impact coral bioerosion by the sea urchin Diadema setosum and whether such impact could be remediated were further investigated in a series of controlled experiments in the field. Although sea urchins were reported to prevent shifting from coral-dominant to algae-dominate phase elsewhere, they were found to cause severe tissue loss and bioerosion at high densities in my study. Thalamita prymna, a common portunid crab in local coral communities, was found to effectively reduce coral damages including bioerosion and surface mortality. Crab predation, an overlooked relationship in coral reefs, can thus be exploited to control urchin corallivory and bioerosion. Prohibiting fish trapping in reef areas could reduce the by-catch of these crabs and protect reefs against urchin attack.

Available in PDF, EPUB and Kindle. Book excerpt: Hong Kong is strategically located between the temperate Japonic and the great tropical Indo-West-Pacific zoogeographic provinces. Influenced by the currents of the South China Sea and the huge outflow of fresh water from the Pearl River, Hong Kong's marine flora and fauna are extremely diverse. Temperate species may appear, if only briefly, during the cooler winter months. Conversely, air and water temperatures remain high enough for a strong tropical component: Hong Kong is comparatively rich in mangrove stands and reef corals are well developed subtidally. There is a strong north-west to south-east salinity gradient further enhancing diversity. Geologically, the Hong Kong shore is a 'drowned' coastline, deeply incised and with former mountain peaks represented by numerous off-shore islands. This book reviews the factors creating and maintaining Hong Kong's living shore, and describes the wide range of plants and animals found within the intertidal boundaries of the shore. A full range from exposure to shelter is to be found, from communities of the sheer rock faces, beaten by the storm waves of the South China Sea, to the denizens of mudflats in high shelter at the heads of harbours and inlets. For the first time the occupants of these various shores are illustrated and described, both as individual species and as components of a rich mosaic of life. The factors of pollution and development that are destroying the diversity of the rich complex of shores are described.

Book excerpt: From 6-25 April 1998, the Tenth International Workshop on the Marine Flora and Fauna of Hong Kong and South China was convened at the Swire Institute of Marine Science of the University of Hong Kong. Thirteen scientists from six countries and twenty-two scientists and students from Hong Kong investigated aspects of the marine flora and fauna of the Cape d'Aguilar Marine Reserve and the southeastern waters of Hong Kong. This was to obtain more information about the newly-established reserve (the only one in Hong Kong) and the changes that had taken place on the seabed in the southern waters since they were dredged between 1992-1995, respectively, and, in the latter case, to see if there had been any subsequent benthic recovery. The Proceedings of the workshop contains thirty-six original research papers dealing with aspects of the taxonomy and anatomy, behaviour and physiology of marine life in Hong Kong and Southern China. Papers also explore aspects of Hong Kong's marine parks and reserves, including the pollution of Hong Kong's marine life with particular reference to the Cape d'Aguilar Marine Reserve, established only in 1996, and the fauna of its territorial southern waters. The Workshop was sponsored by the University of Hong Kong, the Croucher Foundation and the K.C. Wong Foundation so as to bring eminent overseas scientists to Hong Kong to work with their local colleagues and students. The success of the workshop concept is self-evident in the contents and scope of these proceedings. This was the eighth workshop convened in Hong Kong since 1977 and these proceedings have become the single-most important body of information on the long-term changes that have taken place in its marine environment over an extended time-frame. The volumes are also the largest regional repository of information on the marine life of the territorial waters of Hong Kong and the northern rim of the South China Sea. For those with any interest in Hong Kong's marine environment, therefore, this proceedings and its predecessors are essential reading.
