Using existing interviews, logbooks, catch rates from 1997 and later, she developed a novel methodology that allowed her to adjust the older historical data for accuracy. Today, small-scale fishers in the Philippines and other developing countries contribute to the global wild seahorse trade, which totals over 25 million animals per year. The seahorses they catch and sell — for about $0.40 each — end up on display in aquariums, as dried specimens in traditional Chinese medicine, and as curio souvenirs for tourists around the world. “By comparing Project Seahorse data from the past fifteen Project Seahorse PhD student Kerrie O’Donnell (left) meets with local fishers. years with the information we gleaned from the fishers about Kerrie O’Donnell/Project Seahorse the more distant past,” says O’Donnell, “we can better gauge the current rate of population decline and adapt our conservation work accordingly.

Iain Caldwell/ Project Seahorse Our work: Securing shallow seas The first 10 metres of depth along the world’s coastlines is where seahorses and a huge diversity of other marine species live, grow and breed. These coastal ecosystems are also where human beings exert the greatest pressure on our oceans, from overfishing, sea-filling (usually known as land reclamation), and real estate development to aquaculture, land-based runoff, and pollution. Many species and habitats are threatened as a result. We urgently need to take care of these ocean neighbourhoods, where billions of people live, swim, and fish. Project Seahorse’s innovative and interdisciplinary approach, which marries biol- ogy, ecology, social science, and advocacy, gives us distinctive insight into the problem and its possible solutions. We are using this insight — and our considerable academic credibility — to help secure our shallow seas. 5 Securing shallow seas Making marine conservation more efficient “When I tell people I do coral reef conservation, they usually tease me about the tough life I must lead, spending all that time Healthy corals in Danajon Bank, Philippines.

The widely unrecognized reality about conservation is that it’s time-consum- ing, physically demanding and, critically, expensive.” Dr. Molloy has been investigating new ways to make field conservation — specifically, the work of tracking changes in fish populations inside marine protected areas (MPAs) — more time-efficient and cost-effective. Achieving the right balance between scientific rigour and ac- tion is one of the great challenges in marine conservation. Our oceans, especially the first 10 metres of depth, face huge and urgent pressures, yet the work of marine conservation must be done carefully and accurately.

Signature__________________________________ Date______________________________________ University of Washington Abstract Assessing the Feasibility of Expanding Dive Tourism to Danajon Bank, Philippines Audrey J. Kuklok Chair of the Supervisory Committee: Associate Professor Patrick Christie School of Marine and Environmental Affairs Danajon Bank is the only double barrier reef in the Philippines. Found off the northern coast of Bohol Island, central Philippines, Danajon expands over an area of 272 km². The Coastal Conservation and Education Foundation, a Filipino nonprofit, is implementing a project to develop a management plan for Danajon Bank. One of the goals is to increase the economic opportunities for the coastal communities adjacent to the Danajon reefs through marine-related tourism. This study examined the feasibility of expanding dive tourism to this area. The results were derived from two methods: (1) semi-structured interviews with dive business owners and employees; and (2) contingent valuation survey among foreign and local tourists to determine willingness-to-pay an entrance fee to the reefs as a dive destination.

Luritta Whiting Chair of Supervisory Committee: Dr. Patrick J. Christie School of Marine and Environmental Affairs Jackson School of International Studies Abstract The Coastal Conservation and Education Foundation (CCE Foundation), a Philippine environmental organization, in collaboration with Region 7 municipality leaders from Cebu, Leyte, and Bohol, as well as various financial donors, is striving to improve the marine resource management of the Outer Danajon Bank in the Philippines. One of the goals is to develop scuba dive tourism along the Outer Bank, beginning with the municipality of Bien Unido on Bohol Island. Despite previous efforts to attract investors and tourists by the Bien Unido mayor, dive tourism is currently absent from the municipality. During the summer of 2011, the mayor, the CCE Foundation, and a private real estate developer, JCAD Inc., developed an agreement to invest in infrastructure and livelihood training in Bien Unido for the purpose of developing a scuba dive tourism industry. This study is analyzes current community viewpoints on the development of dive tourism in Bien Unido and in four selected dive tourist cites. The study consists of thirty-three qualitative interviews conducted in Bien Unido and four other dive tourist sites as well as 1,117 quantitative surveys conducted with community members throughout the central portion of the Philippines (Region 7).

  • Gender and Marine Protected Areas: a Case Study of Danajon Bank, Philippines
    Maritime Studies https://doi.org/10.1007/s40152-018-0107-7 RESEARCH Gender and marine protected areas: a case study of Danajon Bank, Philippines Danika Kleiber1,2 & Leila Harris3 & Amanda C. J. Vincent3 Received: 19 April 2018 /Accepted: 22 August 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract In this paper, we examine the role of gender in community-based management of marine protected areas (MPAs) in the Central Philippines. MPAs are a common conservation and fisheries management tool in this area, but the relationship between gendered fishing practices and participatory MPA management is rarely considered. In this region, women and men’s fishing practices are often socially and ecologically distinct. MPAs are found in both intertidal and subtidal areas where women and men tend to fish respectively. Based on over 500 interviews in 12 fishing communities, MPAs were largely perceived to be a management tool for men’s fishing. Very few men and women reported a negative effect on their personal fishing or displacement from their fishing area. However, in two communities MPAs that had been in intertidal areas had either been moved or opened specifically to allow for gleaning. Women were less likely than men to report that the MPA had a positive effect on their fishing, but women and men recommended the MPA in equal numbers. Women and men reported attending MPA meetings, but women were less likely to describe active participation in MPA management such as decision making. This research adds to the larger body of work that considers gender and inequality to critically examine issues of power and exclusion in community-based resource management.

Box 68200, Nairobi, Kenya e School of Plant Biology, M090, The University of Western Australia, 35 Stirling Highway, Crawley WA 6009, Australia Abstract Benthic status of 28 near-shore, artisanal, coral reef fishing grounds in the central Philippines was assessed (2000–2002) together with surveys of the seahorse, Hippocampus comes. Our measures of benthic quality and seahorse densities reveal some of the most degraded coral reefs in the world. Abiotic structure dominated the fishing grounds: 69% of the benthos comprised rubble (32%), sand/silt (28%) and dead coral (9%). Predominant biotic structure included live coral (12%) and Sargassum (11%). Rubble cover increased with increas- ing distance from municipal enforcement centers and coincided with substantial blast fishing in this region of the Philippines. Over 2 years, we measured a significant decrease in benthic ‘heterogeneity’ and a 16% increase in rubble cover. Poor benthic quality was con- comitant with extremely low seahorse densities (524 fish per km2).
