Over the past decades fisheries policies have been mainly aimed at encouraging capacity reduction in over-exploited fisheries. Correspondingly, research has focused on developing incentives to exit fisheries rather than investigating entry behaviour. However, with ageing and also fewer fishery participants, concern regarding sectoral renewal is increasing. The second-hand market is an important...
As long as total effort cannot be completely controlled, a more thorough understanding of fishers’ supply response decisions will be beneficial for fishery managers. In this paper, we present a model of fishers’ gear choice, which is empirically estimated on a panel of Swedish demersal trawlers. The approach allows for heterogeneity both in production technology and in risk preferences. Stochas...
This article is a commentary on the experiences that motivated my decision to become a human ecologist and ethnobiologist. These experiences include the pleasure of studying and of having the sense of being within nature, as well as the curiosity towards understanding the world and minds of local people. In particular, such understanding could be driven by addressing the challenging questions t...
This paper explores some key challenges the Mexican government may face when implementing climate change adaptation initiatives in coastal lagoon communities in the Mexican state of Tabasco, in the Gulf of Mexico. I discuss some challenges state initiatives of this type may encounter considering the existence of local contentious political issues among various actors – fishers and the state-own...
We investigate long-term changes in the Mediterranean marine resources driving the trawl fisheries by analysing fishers' perceptions (Traditional Ecological Knowledge, TEK) throughout the Mediterranean Sea during the last 80 years. To this end, we conducted an extended set of interviews with experienced fishers that enabled us to classify species (or taxa) as 'decreasing' or 'increasing' both i...
In pursuing their livelihood, fishers develop strategies when faced with changes in regulations and other fishery conditions. Changes involve each individual in a decision‐making process governed by his/her own goals or constraints. Despite this reality, the complex dynamics of fishing has usually been ignored in designing management initiatives, which has contributed to ...

Abstract Shifts in marine species distributions associated with climate change occur across large spatial areas and long time periods. Marine recreational fishing occurs most countries many participants interacting regularly the environment, yet there have been few studies on views of fishers towards change. This study aims to assess perceptions for a boat-based fishery Western Australia, where...
The context for this study was to document fishers’ experience-based knowledge is reliable and can be included in citizen science as supplementary information scientific research. Fishers’ contributes important understanding of the environment marine ecosystem. Hence, over time not always regarded knowledge. There a lack on how fishers have acquired when they had formal education what way used ...
