Weekly survey of fish sold by the roadside in Moorea, French Polynesia in 2014 and 2015 (Coral reef fishery project)


Dataset Description
This dataset includes the results of a survey on fish sold by the roadside in Moorea, French Polynesia, administered in 2014-2015 at Papetoi, Haapiti, and Afareaitu.

Acquisition Description
Each Sunday morning from June 2014 through November 2015, an observer surveyed fish being sold along the roadside on the island of Moorea.On each survey date, the observer drove along the ring road which circles the islands along the shoreline, stopping to interview anyone selling fish by the road.With the permission of the seller, the observer photographed the fish for sale, which were typically presented on strings hanging from large racks.The observer also asked a series of questions to the seller about how the fish were caught.
Participation in this survey was voluntary, and so the catch reported here does not represent a complete sample of fish being sold by the roadside.A single observer performed all surveys, so a few Sundays in this period were not sampled because of logistical constraints Fish in each photograph were identified to the highest taxonomic resolution possible, often to species but usually at least genus.The size of each fish was estimated by drawing a line from nose to tail and then comparing the length of that line to the length of a 0.5 m sizing bar that was included in each photograph.Image analyses were performed in the computer program "imageJ" (Rasband, NIH) and species identities and sizes have been merged together with the survey responses of the fish sellers in the data set provided.

Processing Description
Data have been inspected and outliers checked.The location_sold variable has been standardized to the level of an administrative commune (location_caught remains in the form that the seller reported it).Fish that could not be identified at least to family have been omitted from the data.

BCO-DMO Processing notes:
- This project will contribute to more sustainable management of coral reefs by identifying pathways that confer resilience, highlighting emerging vulnerabilities, and suggesting policy initiatives in areas such as integrated coastal zone management and sustainable development planning.An integrative social and natural science approach will be employed that addresses place-based questions about resilience, sustainability and adaptive capacity of coastal systems.A framework will be developed for addressing more complex questions about the Moorea social-ecological system, and this will provide a model for the integration of ecology and social science in other coastal systems.Research results will be disseminated broadly through stakeholder workshops, and graduate students will be engaged in all aspects of the work.While the dynamics of state shifts are fundamental to understanding the resilience and long-term sustainability of coral reef social-ecological systems, the interplay between anthropogenic and ecological feedbacks is poorly understood in these systems.Systems with high population densities, widespread coastal development and intense resource exploitation typically show declines in the critical adaptive capacities that underpin resilience to local environmental variability.However, Moorea has maintained its resilience despite rapid development.This project will explore how the complex feedbacks in the Mo'orea coral reef social-ecological system maintain its capacity to withstand large-scale ecological disturbances.The study will involve interdisciplinary collaboration between social and natural scientists.Anthropological fieldwork focusing on the human dimensions of coral reef use, traditional governance, and indigenous ecological knowledge, will document how local communities perceive, respond to, and manage changes in ecosystem state.Ecological models will describe the dynamics of coral, algal and fish communities, including the feedbacks that make these communities susceptible to abrupt shifts in ecosystem state.These components will be integrated in a systems modeling framework that includes feedbacks both within and between the human and natural communities, quantitatively modeling how humans change their behavior as a function of ecosystem state and how the ecosystem is affected in turn by human activities.A key objective is to bridge the gap between data collected by social scientists and the dynamic ecosystem models developed by ecologists, as this is crucial to

://www.nsf.gov/funding/pgm_summ.jsp?pims_id=504816Coverage: USCoastal SEES is focused on the sustainability of coastal systems.For the most recent solicitation, NSF defines coastal systems as the swath of land closely connected to the sea, including barrier islands, wetlands, mudflats, beaches, estuaries, cities, towns, recreational areas, and maritime facilities; the continental seas and shelves; and the overlying atmosphere.Humans benefit from their use of coastal environments for enjoyment, dwelling, food, industry, and commerce, and benefit from the myriad of ecosystem services that coastal environments provide.However, human activities often result in physical, chemical, and ecological alterations that influence and interact with natural state and variability, over a range of spatial and temporal scales.A major challenge is to understand the dynamics of this coupled humannatural system in order to inform societal decisions about the uses of coastal systems, including for economic, aesthetic, recreational, research, and conservation purposes.Scientific understanding is foundational and must include an understanding of reciprocal feedbacks between humans and the natural environment; how people and organizations interpret, assess, and act upon scientific and other evidence; and how they weigh these interpretations against other interests to influence governance and decision-making.Thus, coastal sustainability relies on broad and intimately interconnected areas of scholarship about natural and human processes.Coastal SEES projects will be expected to lead to generalizable theoretical advances in natural sciences and engineering while, at the same time, integrating key aspects of human processes required to address issues of coastal sustainability.Detailed information about the SEES program is available from NSF (http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=504707).
