Abstract Marine ecosystems evolve under many interconnected and area‐specific pressures. To fulfil society's intensifying diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning broader‐scope management of resources is necessary. Integrated ecological–economic fisheries models ( IEEFM s) systems are needed to evaluate impacts sustainability potential actions understand, anticipate ecological, economic social dynamics at a range scales...

Impact of technological creep on fishing effort mortality, for a selection European fleets–ICES Journal Marine Science, 64, 192–209. Face-to-face interviews were conducted to identify the main changes in gear vessel technology that may have improved efficiency number French, Danish, Basque fleets over past few decades. Important include gradual...
Small-scale fisheries operating in coastal areas represent 90% of worldwide and 84% the European Union (EU) fleet. They are globally vital for populations as they sustain a major source animal protein, provide numerous job opportunities, livelihoods, support economic activities culturally central. In EU Outermost Regions (ORs), these subject to Common Fisheries Policy (CFP) related regulations, although benefit from derogatory or specific regimes instance regarding fleet renewal. Obligations...
Abstract Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of demographic transition characterizing many countries world. Fisheries marine ecosystems constitute difficult application this bio‐economic challenge. Many experts scientists advocate an ecosystem approach to manage socio‐ecosystems for their sustainability resilience. However, ways by which operationalize ecosystem‐based fisheries management ( EBFM ) remain...
Most fisheries worldwide remunerate their crew with a share system, where receive part of the revenues or less costs, rather than fixed wage. Although labor is one main costs in and remuneration system has strong influence on firm behavior its economic performance, little attention been paid it. In salaries can significantly increase when performance vessel improves. This allows to capture rent. Bioeconomic analyses are performed for Bay Biscay nephrops fishery management targets. Results...
In most fisheries worldwide, crew are paid through different shared remuneration systems rather than a fixed wage. systems, wages can significantly increase when the economic performance of vessels improve, and consequently provide incentives to workers. However, in recent years, mainly due high overexploitation levels that lead reduced productivity lower salaries have lost their attractiveness. Different applied world-wide described analyzed comparatively. Results explain how rent...
Several fleets with various fishing strategies operate as a mixed fishery in the Bay of Biscay. Among main fleets, bottom trawlers target Norway lobster (Nephrops norvegicus) and, together gillnetters, they also catch hake (Merluccius merluccius). Trawling leads to average-size catches that are below minimum landing size (MLS); such discarded since cannot be sold. These discards result negative impacts on stock renewal, most them do not survive. This results an economic loss for both and...
The COVID-19 outbreak and subsequent public health interventions have depressed demand disrupted supply chains for many fishing businesses. This paper provides an analysis of the impacts on profitability EU fleets. Nowcasting techniques were used to estimate impact pandemic economic performance fleet in 2020 2021. Our results show that this sector was smaller than initially expected overall profits remained positive. part due low fuel prices reduced operating costs fishing, early response...

Ensuring representative economic data: survey data-collection methods in France for implementing the Common Fisheries Policy. – ICES Journal of Marine Science, 68: 1792–1799. Since 2001, Ifremer has implemented an data collection programme (EDCP) within Data Collection Framework EU. It aims to obtain from a sample vessels entire French fishing fleet. This paper presents strategies used vessel...
