The riparian Coleoptera fauna of the river Altaelva, Finmark County, Northern Norway, has been surveyed in summer 2002 and 2003. The river Altaelva has been regulated since 1987, and my objective was to investigate the effect of the regulation on the riparian fauna. In total, 37 localities were examined, and four methods were used: hand collecting, washing without area limitation, quadrate sampling ...

Farm animals are virtually ignored in tourism studies concerning sustainability and justice. This study argues that this conflicts with animal ethics and is a missed opportunity to reflect on sustainability and justice in tourism. It adopts an ecofeminist care ethics perspective and conducts autoethnographic research into farm animals, considered ‘silenced’ individuals belonging to a marginalised ...

The initial stage of the emerging Norwegian snow crab (SC) industry was characterized by excessive optimism, and this case study explores whether the early entrants have gained sustainable first-mover advantages. Unfortunately, the investments have not been profitable as the firms made a yearly average negative profit of more than 10% in the period examined. Accordingly, the early entrants have so ...

The relationship between sustainability, competitive advantages, and performance is a topic with no conclusive results in the tourism industry. To contribute to the debate, the purpose of this study is i) to analyze the influence of sustainability on cost and differentiation competitive advantages and ii) to examine the possible synergistic relationship between sustainability and performance. ...

There is a push for transition to sustainable blue food systems in the High North. An interdisciplinary group of Fram Centre researchers have looked closer at the drivers motivating the transition and identified a set of barriers to sustainable blue food systems in northern Norway.

Aquaculture in Ghana has been in existence for over 50years. However, it has been less productive despite its high potential for commercial and other scales of production. The Volta Lake presents a huge available resource for the success of cage aquaculture in the country. The cage system of production was introduced in 2001 according to Kasam (2014). This system of aquaculture production even ...

Ornamental fish trade represents an important economic sector with an export turnover that reached approximately 5 billion US dollars in 2018. Despite its high economic importance, this sector does not receive much attention. Ornamental fish husbandry still faces many challenges and losses caused by transport stress and handling and outbreak of diseases are still to be improved. This review will ...

The effects of harvest and fluctuating environment on inter-dependent predators and prey are complex and not well-known. We define a stochastic model where the predators and prey dynamically interact. The novelty of the model holds on the fact that predators and prey dynamics are simultaneously affected by correlated environmental noises. Interacting predators and prey are harvested using a proportional ...

Oceanographic changes adjacent to Antarctica have global climatic and ecological impacts. However, this is the most challenging place in the world to obtain marine data due to its remoteness and inhospitable nature, especially in winter. Here, we present more than 2000 Conductivity-Temperature-Depth (CTD) profiles and associated water sample data collected with (almost uniquely) full year-round ...

Calanoid copepods dominate mesozooplankton communities in temperate and Nordic seas. The ability of copepods to remain and feed in productive surface waters depends on their ability to overcome downward flows. In this study, we assessed the swimming performance of subarctic Calanus spp. and tested how the copepods can retain their vertical position in a representative range of downward currents ...
