There are tradeoffs in managing fisheries, and ideally such tradeoffs should be known when setting fisheries policies. An aspect of this, which is rarely considered, is the spin-off effect of different fisheries: the economic and social benefits that fisheries generate through processing through distribution and on to the end consumer. This study e...
Small-scale fisheries are globally marginalized by management institutions; thus, they have to endure the consequences of ineffective regulations, environmental uncertainty, social traps and market inequity. Small-scale fisheries in Peru, one of the world's leading fishing countries, are important contributors to national employment, food security...
Improving small-scale fishers' wellbeing is a core policy objective in efforts to achieve just, equitable and sustainable futures. Nonetheless, fishers' wellbeing is rarely assessed or monitored over time using quantitative indicators. We evaluated the socioeconomic performance and evolution of two small-scale fishing communities of northern Peru u...
Supply chain opacity enables seafood fraud, human rights abuses and unsustainable resource use. To boost seafood transparency, it is vital to understand what is being caught or farmed, by whom, how, where and when. Catch reconstructions, such as those from the Sea Around Us, achieve this. Yet, linking producers’ outputs with downstream supply chain...
Fisheries are complex systems. Food web models are increasingly being used to study the ecological consequences of fisheries policies and environmental change on such systems around the world. Nonetheless, these consequences extend well into the social, economic, cultural, and political domains of such systems. The main goal of this contribution is...

The rapid expansion of the ocean economy—including industries like oil and gas, renewable energy, fishing, aquaculture, tourism, and shipping—is placing immense pressure on marine env...
The exceptional diversity of shallow‐water marine fishes contributes to the nutrition of millions of people worldwide through coastal wild‐capture fisheries, with different species having diverse nutritional profiles. Fishes in ecosystems are reservoirs of micronutrients with benefits to human health. Yet, the amount of micronutrients contained in...
The study of past subsistence offers archeologists a lens through which we can understand relationships between people and their homelands. səl̓ilwətaɬ (Tsleil-Waututh) is a Coast Salish Nation whose traditional and unceded territory centers on səl̓ilwət (Tsleil-Wat, Burrard Inlet, British Columbia, Canada). səl̓ilwətaɬ people were fish specialists...
Voluntary land conservation, including privately protected areas (PPAs), is a key component of enabling the future of biodiversity on Earth. Accordingly, the question of motivations has preoccupied conservation social science. True motivations are difficult to ascertain, however, even for ourselves.
Accordingly, we explore a novel narrative elicita...
We present a novel adaptation of the classic discrete delay‐difference model, a continuous delay‐differential model (cDDM), which can adequately represent population dynamics of stocks that turn over rapidly and continuously over time (e.g., small pelagic fish, small tunas, and shrimps). We used the Northern‐Central Peruvian anchoveta stock ( Engra...

Piura es una región del norte de Perú que destaca por su pesca artesanal, su industria procesadora y exportadora de productos para consumo humano directo (CHD) y su gastronomía marina. Usando información primaria y secundaria, se caracterizó la cadena de valor de la actividad pesquera regional durante el 2014 y se estimaron indicadores de producció...
Significance
Charging industries for exploiting natural resources ensures that the owner of the resources—the public—receives compensation for their usage. Although fishery resources within exclusive economic zones constitute most of the global marine capture production, it is unclear whether fishing industries harvesting these resources are charge...
Peru's initial catch reconstruction, covering the 1950-2010 period, was updated to 2018. This process improved the taxonomic resolution of the catch, as well as the accuracy of Sea Around Us-assigned 'end use' and 'gear type' categories to the Peruvian catch. Detailed descriptions of the methods are given, mostly on a per species basis. We discuss...
1. Marine ecosystems play a key role in human wellbeing, particularly in the Global South through small-scale fisheries (SSF). While many have speculated that such activities are central to the provision of cultural benefits (such as cultural identity and heritage values), there are key information gaps regarding SSF cultural contributions to socie...
En los ecosistemas marinos se realizan múltiples actividades extractivas entre las cuales sobresale la pesca industrial debido a la magnitud de sus capturas e importancia socioeconómica. No obstante, la pesca industrial actualmente enfrenta tres retos a fin de asegurar su desarrollo a perpetuidad. Éstos son: (1) garantizar el manejo sostenible del...
A third of global fish stocks are overexploited and many are economically underperforming, resulting in potential unrealized net economic benefits of USD 51 to 83 billion annually. However, this aggregate view, while useful for global policy discussion, may obscure the view for those actors who engage at a regional level. Therefore, we develop a me...

Conservation organizations promoting sustainable seafood have had greater success when chefs are empowered as agents of change in favour of sustainable seafood. Peru is experiencing a gastronomic revolution with seafood at its core, and Peruvian top chefs are being approached by conservation organizations to become environmental advocates. Within t...
This paper analyzes voluntary cleanups organized by the Great Canadian Shoreline Cleanup (GCSC) along the coast of British Columbia (2013–2016). Cleanup performance indicators, litter composition and diversity were compared between years and across areas (i.e., North Coast of British Columbia, Inner Coast of Vancouver Island, West Coast of Vancouve...
Misconceptions, lack of knowledge, and negative attitudes towards sharks act as barriers preventing actions required to tackle threats to shark populations, limiting the success of global shark conservation initiatives. Peru, a major player for the international trade of shark products, recently approved the ‘National Action Plan for the Conservati...

Persistent organic pollutants were assessed in Humboldt Penguins ( Spheniscus humboldti) from the Punta San Juan Marine Protected Area, Peru, in the austral winter of 2009. Plasma samples from 29 penguins were evaluated for 31 polychlorinated biphenyl (PCB) congeners and 11 organochlorine pesticides (OCPs) by using gas chromatography coupled to an...
Peru is home to the world's biggest fishery with catches of over 95 million tonnes of anchoveta (Engraulis ringens), since 2000, yet one in six small children in Peru suffer from chronic malnutrition. This is not because anchoveta is unsuitable for human consumption—on the contrary, they are nutritious, tasty and available year-round, close to the...
La valoración que se presenta a continuación busca destacar el valor de los servicios ecosistémicos generados por el Gran Ecosistema Marino de la Corriente de Humboldt (GEMCH) para el ser humano y para el desarrollo económico de Perú y Chile.
Para lograr la valoración de los servicios ecosistémicos se identificaron los servicios ecosistémicos pro...
Cumulative human impacts across the world's oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communities might be at risk of decline or extinction in the southern hemisphere. We sought to determine the most important threats to penguins and to suggest means...

The world’s biggest fishery is for anchoveta in the Peruvian upwelling ecosystem. Anchoveta fluctuates strongly in abundance, and this in turn impacts the rest of the ecosystem as well as the many Peruvians who rely on fisheries for food and employment. We have developed a management model of the Peruvian EEZ, which combines an ecological food web...
The Peruvian fishing sector and policies have through the last fifty years focused on the anchoveta, which forms the basis for the world’s biggest fishery. The Peruvian upwelling ecosystem is, however, diverse and productive, it harbors many other important species, and in addition to the anchoveta reduction fisheries it forms the basis for a very...
