The objective of the paper is to analyse and to simulate fishers dis-investment behaviour especially in the context of national decommissioning plans. We first examine the development of the French buyback policy and its links with the Common Fishery Policy objectives. The paper focus on the general conditions of the plans, especially on the basis of premiums offered to fishers to leave the ind...

Territorial user rights for fisheries are being promoted to enhance the sustainability of small-scale fisheries. Using Chile as a case study, we designed a market-based program aimed at improving fishers' livelihoods while incentivizing the establishment and enforcement of no-take areas within areas managed with territorial user right regimes. Building on explicit enabling conditions (i.e., hig...

Inland capture fisheries and aquaculture have a number of divergent as well as overlapping relationships. In general, fishers are hunter/gatherers and socio-culturally quite distinct from fish farmers. The essential components of these cultures influence the way they view their respective environments and its resources. Institutionally, fisheries output is often controlled by managing the fishe...

Knowledge of dispersal-related gene flow is important for addressing many basic and applied questions in ecology and evolution. We used landscape genetics to understand the recovery of a recently expanded population of fishers (Martes pennanti) in Ontario, Canada. An important focus of landscape genetics is modelling the effects of landscape features on gene flow. Most often resistance surfaces...

In this paper I evaluate the merit of costly signaling theory (CST) as a paradigm for understanding why men of Ifaluk atoll torch fish. I argue that torch fishing is a handicap that signals men’s productivity. Consistent with CST, torch fishing is observed by the predicted audience (women), energetically costly to perform, and a reliable indicator of the frequency a man fishes during the trade ...

Wildlife managers often need to assess the current health status of wildlife communities before implementation of management actions involving surveillance, reintroductions, or translocations. We estimated the sensitivity and specificity of a commercially available domestic canine rapid diagnostic antigen test for canine parvovirus and a rapid enzyme-linked immunosorbent assay for the detection...

Safety management regulation was introduced almost twenty years earlier for Norwegian seafarers than coastal fishers, although both groups work in industries with high accident frequencies. In this study, and fishers' perspectives on safety requirements is studied, through empirical data from interviews observation conducted over several years, the aim of informing future development management...

Marine reserves have been widely promoted as conservation and fishery management tools. There are robust demonstrations of conservation benefits, but fishery benefits remain controversial. We show that marine reserves in Florida (United States) and St. Lucia have enhanced adjacent fisheries. Within 5 years of creation, a network of five small reserves in St. Lucia increased adjacent catches of ...
