Counting the catch of a fishermen.
Recently, a member of the SPACES team attended a regional workshop in Nosy Be, Madagascar from 27 to 28 April, 2015. The workshop was convened by the Wildlife Conservation Society (WCS) and Dr Emily Darling with the aim to bring together various researchers working on coral reef fisheries in the Western Indian Ocean (WIO).
The workshop was attended by about 17 people, representatives of the following countries and organizations: Madagascar (WCS, Blue Ventures, WWF, CNRO and HEAL/Darwin), Mozambique (UniLurio and SPACES), Tanzania (University of Dar es Salaam) and Kenya (WCS).
Gleaning on the reef flat is often a very important source of food and income. Here a SPACES team member documents what types of reef organisms are collected in Maringanha
At the workshop the following topics were discussed: (1) the WCS upcoming program that aims to globalize the monitoring efforts on coral reef fisheries; (2) which indicators for coral reef fisheries in the WIO should be monitored; and (3) the current monitoring programmes of WIO coral reef fisheries at sites in Kenya, Madagascar, Tanzania and Mozambique. Information on this last topic was provided by the representatives of each organization previous mentioned.
This workshop and project aims to develop a coordinated database of monitoring indicators and outline the data sharing agreements across organizations that would be necessary for future collaborations in the WIO.

Artisanal fisheries in Cabo Delgado, Mozambique: rural vs urban fishing centers
Pdf link About This working paper investigates the relationship between gear, catch and income generated by the fishers in different seasons. SPACES researchers collected data using fish catch surveys at landing sites in Pemba town, Vamizi and Lalane. A standard questionnaire was used to collect the effort and location of the fishery. The fishery shows […]

Linking reef ecology to island building: Parrotfish identified as major producers of island-building sediment in the Maldives. Geology 2015
Link to pdf (Open Access) Abstract Reef islands are unique landforms composed entirely of sediment produced on the surrounding coral reefs. Despite the fundamental importance of these ecological-sedimentary links for island development and future maintenance, reef island sediment production regimes remain poorly quantified. Using census and sedimentary data from Vakkaru island (Maldives), a sand-dominated atoll […]
Remote coral reefs can sustain high growth potential and may match future sea-level trands. Nature Scientific Reports 2015
Link to pdf (Open Access) Abstract Climate-induced disturbances are contributing to rapid, global-scale changes in coral reef ecology. As a consequence, reef carbonate budgets are declining, threatening reef growth potential and thus capacity to track rising sea-levels. Whether disturbed reefs can recover their growth potential and how rapidly, are thus critical research questions. Here we […]
Similar impacts of fishing and environmental stress on calcifying organisms in Indian Ocean coral reefs. Marine Ecology Press Series 2016
Link to pdf (Open Access) Abstract Calcification and reef growth processes dominated by corals and calcifying algae are threatened by climate and fishing disturbances. Twenty-seven environmental, habitat, and species interaction variables were tested for their influence on coral and calcifier cover in 201 western Indian Ocean coral reefs distributed across ~20° of latitude and longitude […]
Environmental variability indicates a climate-adaptive center under threat in northern Mozambique coral reefs. Ecosphere 2017
Link to pdf (Open Access) Abstract A priority for modern conservation is finding and managing regions with environmental and biodiversity portfolio characteristics that will promote adaptation and the persistence of species during times of rapid climate change. The latitudinal edges of high-diversity biomes are likely to provide a mixture of environmental gradients and biological diversity […]
Drivers and predictions of coral reef budget trajectories. Proceedings Of The Royal Society B-biological Sciences 2017
Link to pdf (Open Access) Abstract Climate change is one of the greatest threats to the long-term maintenance of coral-dominated tropical ecosystems, and has received considerable attention over the past two decades. Coral bleaching and associated mortality events, which are predicted to become more frequent and intense, can alter the balance of different elements that […]

New paper from SPACES team members shows the positive correlation between the orange-lined triggerfish and calcifier cover
SPACES Co-investigators, Tim McClanahan and Nyawira Muthiga, have recently published the paper, Similar impacts of fishing and environmental stress on calcifying organisms in Indian Ocean coral reefs (Open Access– free to read) in the Marine Ecology Progress Series. They investigated coral and calcifier cover in 201 western Indian Ocean reefs. McClanahan and Muthiga found that coral and calcifier cover […]
How important are parrotfish for coral reef islands?
Parrotfishes are a beautiful, colourful and ubiquitous group of fishes that are present on coral reefs around the world. They’ve received a lot of attention due to their importance in both fisheries, and in how they can help to maintain coral reef health through preventing outbreaks of fleshy macroalgae, that can overgrow and out-compete corals.
