Reef Fishes Reef Fishes to Work Towards a Common Goal Field Guide to About Mangroves for the Future Field Guide to Mangroves for the Future (MFF) is a unique partner-led initiative to promote investment in coastal ecosystem conservation for sustainable development. It provides a collaborative platform among the many different agencies, sectors and countries who are addressing challenges to coastal ecosystem and livelihood issues, Reef Fishes Reef Fishes to work towards a common goal. MFF builds on a history of coastal management interventions of Sri Lanka before and after the 2004 Indian Ocean tsunami, especially the call to continue the momentum and partnerships generated by the immediate post-tsunami response. It initially focused on the countries worstaffected by the tsunami; India, Indonesia, Maldives, of Sri Lanka Seychelles, Sri Lanka, and Thailand. MFF has expanded to include Bangladesh, Cambodia, Pakistan and Viet Nam. MFF will continue to reach out other countries of the region that face similar issues, with an overall aim to promote an integrated ocean wide approach to coastal zone management. The initiative uses mangroves as a flagship ecosystem, but MFF is inclusive of all coastal ecosystems, including coral reefs, estuaries, lagoons, sandy beaches, sea grasses and wetlands. Its long-term management strategy is based on identified needs and priorities for long-term sustainable coastal ecosystem management. These priorities emerged from extensive consultations with over 200 Arjan Rajasuriya individuals and 160 institutions involved in coastal management. MFF seeks to achieve demonstrable results in influencing regional cooperation, national programme support, private sector engagement and community action. This will be achieved using a strategy of generating knowledge, empowering institutions and individuals to promote good governance in coastal ecosystem Arjan Rajasuriya management.

This book fills a long felt gap, as country-specific field guides for Sri Lanka have not been readily available for marine enthusiasts to learn about reef fishes in our waters. This publication will be immensely useful for those who are interested to learn about reef fishes and may also help officials in the identification of some of the species of reef fishes protected by law. This is the first in the series of field guides describing 158 species of reef fishes in Sri Lankan coastal waters. Subsequent volumes will cover the rest of the species. We believe this Field Guide to Reef Fishes of Sri Lanka will enhance awareness about these wonderful animals and their habitats for better conservation action. Shamen Vidanage Acting Country Representative IUCN, Sri Lanka ix Preface Ever since I first looked underwater more than 40 years ago, I have been fascinated by the diversity and number of fish on our reefs. Reef fish add colour and movement to a reef and fish watching is a fascinating and rewarding activity for snorkelers and divers. Knowing the names of fish adds to one’s enjoyment, especially in later discussions of what was observed underwater or to identify a fish from an underwater photograph. Identifying fish is equally important for a student or a naturalist who wants to record the diversity of reef fish at a location. Reef fish identification guides were not readily available in Sri Lanka forty years ago, and I often used the names

Several introduction pathways contribute to these introduction, including Lessepsian migration via the Suez Canal, accounting for approximately 100 fish species, and intentional or non-intentional aquarium releases, accounting for at least 18 species introductions. In the context of the citizen science project of iSea “Is it alien to you?… Share it”, several citizens are engaged and regularly report observations of alien, rare or unknown marine species. The project aims to monitor the establishment and expansion of alien species in Greece. In this study, we present the first records of two popular high-valued aquarium species, the scissortail sergeant, Abudefduf sexfasciatus and the sohal surgeonfish, Acanthurus sohal, in along the Mediterranean coastline of Greece. The aggressive behaviour of the two species when in captivity, and the absence of records from areas close to the Suez Canal suggest that both observations are the result of aquarium intentional releases, rather than a Lessepsian migration.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region.

Environmental Studies The Role of Threespot Damselfish (Stegastes planifrons) as a Keystone Species in a Bahamian Patch Reef. (76 pp.) Director of Thesis: Molly R. Morris Abstract The purpose of this research is to identify the role of the threespot damselfish (Stegastes planifrons) as a keystone species. Measurements from four functional groups (algae, coral, fish, and a combined group of slow and sessile organisms) were made in various territories ranging from zero to three damselfish. Within territories containing damselfish, attack rates from the damselfish were also counted. Measures of both aggressive behavior and density of threespot damselfish were correlated with components of biodiversity in three of the four functional groups, suggesting that damselfish play an important role as a keystone species in this community. While damselfish density and measures of aggression were correlated, in some cases only density was correlated with a functional group, suggesting that damselfish influence their community through mechanisms other than behavior.

    Effects of Coral Bleaching on Coral Reef Fish Assemblages Nicholas A J Graham A Thesis submitted to Newcastle University for the Degree of Doctor of Philosophy School of Marine Science and Technology Supervisors: Professor Nicholas V C Polunin Professor John C Bythell Examiners: Professor Matthew G Bentley Dr Magnus Nyström First submitted: 1st July 2008 Viva-Voce: 1st September 2008 Abstract Coral reefs have emerged as one of the ecosystems most vulnerable to climate variation and change. While the contribution of climate warming to the loss of live coral cover has been well documented, the associated effects on fish have not. Such information is important as coral reef fish assemblages provide critical contributions to ecosystem function and services. This thesis assesses the medium to long term impacts of coral loss on fish assemblages in the western Indian Ocean. Feeding observations of corallivorous butterflyfish demonstrates that considerable feeding plasticity occurs among habitat types, but strong relationships exist between degree of specialisation and declines in abundance following coral loss. Furthermore, obligate corallivores are lost fairly rapidly following decline in coral cover, whereas facultative corallivores are sustained until the structure of the dead coral begins to erode. Surveys of benthic and fish assemblages in Mauritius spanning 11 years highlight small changes in both benthos and fish through time, but strong spatial trends associated with dredging and inter-specific competition. In Seychelles, although there was little change in biomass of fishery target species above size of first capture, size spectra analysis of the entire assemblage revealed a loss of smaller individuals (<30cm) and an increase in the larger individuals (>45cm).
