Tourism livelihoods in Smøla, Norway
2017
Tourism in islands and archipelagos provides numerous advantages and disadvantages. This paper analyses a previously unpublished case study of island tourism livelihoods from the archipelago of Smøla, Norway, examining the pros and cons of implemented or proposed tourism livelihoods based on a snapshot from 2008-2009. Smøla’s tourism livelihoods are categorised by nature, technology focusing on the wind farm, fishing and hunting, cultural landscapes, culture, and history. As with many other island and archipelago case studies, the most suitable approach could be tourism-supplemented, rather than tourism-dependent, livelihoods with the principal challenge being finding the right scale for Sm…
Are people willing to pay for eco-labeled wild seafood? An overview
2017
In the last two decades, eco-labeled seafood has been becoming an instrument of sustainability directed towards consumers, addressing a market-based incentive for better management of fisheries. In this context, several studies across the countries have been conducted about how much consumers are willing to pay for fish caught by certifiably sustainable fishing activities. In this direction, the aim of this study was to systematize the available information about the willingness-topay (WTP) more for eco-labeled wild seafood. Therefore, only papers published on ISI journals were searched on “Web of Knowledge” and “SciVerse Scopus” platforms, using the combinations of the following key words:…
The Adaptation of Professional Fishing to Diminished Vendace Stocks: The Case of Finnish Inland Waters
1999
Abstract The large number of lakes covering 10% of Finland's surface area provide an opportunity for both full-time and part-time professional fishing. However, the development of the fishing industry is hindered by unpredictable fluctuations in fish stocks, by the elaborate hierarchy of the fisheries system, as well as by certain features of Finnish professional fishing, such as the small size of fishing enterprises, the scattered pattern of production, and long transportation distances to the core demand areas. According to Finnish catch statistics, the stock of vendace Coregonus albula has clearly diminished since the mid 1980s. Our results show that full-time professional fishermen diff…
Pelagic food web as the basis of fisheries in Lake Tanganyika: A bioenergetic modeling analysis
2002
Fisheries in Lake Tanganyika, East Africa, are mainly based on two predominantly planktivorous clupeids (Stolothrissa tanganicae and Limnothrissa miodon) and a centropomid predator (Lates stappersi), caught with lift nets, purse seines, and beach seines by traditional, artisanal, and industrial fishers. The biological basis and sustainability of the present fisheries were assessed in a comprehensive project “Research for the Management of the Fisheries on Lake Tanganyika” in 1992–1998. Production in the whole lake was estimated for the entire pelagic food chain leading to the commercially important fish species. Preliminary calculations based on a constant production efficiency suggested th…
Deep-sea shrimp fishery in Sicily: The economic performance of the shrimp trawling fleet in the ports of Mazara del Vallo, Sciacca, and Porto Empedoc…
2006
Shrimp fishing in Sicily is carried out by fishing companies using trawlers and multifunctional vessels equipped with trawling nets, in a complex and worrisome context, because of the decrease in catch over the last few years. After analysing the structural characteristics of Sicilian trawling, the study concentrates on the three most important shrimp fishing ports in Sicily: Mazara del Vallo, Sciacca, and Porto Empedocle. For each fleet, through a sample analysis, economic performance has been evaluated for the period from 2001 to 2003. Finally, a comparative analysis of the economic performance of the surveyed companies is carried out through a comparison of daily economic productivity in…
Lo sviluppo sostenibile della pesca nella marineria di Mazara del Vallo
2011
In a place like Sicily, where sea fishing and port activities are part of the territory, history and culture, fishery has always been vital to man and, for this reason, today it must be studied, protected and helped in the difficult transition towards long-term sustainability. Fishing is a driving sector for Mazara economy both for number of working days during the fishing season, and for industrial activities operating around this field (transformation, packaging, and distribution). A micro-economic analysis was carried on a sample of fishing enterprises in order to analyze the problems of the here studied seamanship. The analysis is based on the employers’ interviews. The collected data h…
Intention of coastal communities to support climate change mitigation policies for fish and marine ecosystem preservation
2021
Purpose This paper aims to assess the willingness of individuals living in coastal communities affected by climate change to financially support mitigation policies towards the preservation of marine ecosystems and fish resources and to identify the key drivers of their behaviour. Design/methodology/approach A survey was carried out involving 994 people living in three main Italian coastal communities. To investigate the main factors affecting Italian coastal communities’ willingness to pay (WTP) to support climate change mitigation measures to protect the marine ecosystem and fishery resources, a Tobit regression model was implemented. Findings The results show that these communities are …
The criminal prosecution of illegal fishing and the jurisdiction of Spanish courts
2022
This paper examines the possibilities of criminally prosecuting illegal fishing in maritime zones based on crimes established in Spanish legislation. In order to carry out this analysis, a distinction has been made between prosecution based on the place in which acts of illegal fishing are committed (ratione loci), who is responsible for this illicit activity (ratione personae), and the criminal relevance of the incriminating conduct (ratione materiae). This reveals the scope of the criminal prosecution which Spanish courts can carry out and whether this is sufficient to guarantee marine biodiversity to the benefit of the international community.
Trawling disturbance effects on the trophic ecology of two co-generic Astropectinid species
2015
Physical disturbance by trawling can have both negative and positive effects on populations of scavenging benthic organisms. In the present study the impact of fishing activity on feeding behaviour of the two Astropectinids, Astropecten bispinosus and A. irregularis , was assessed based on stomach contents analysis. The study was carried out along trawled seabed highlighting the positive response of the two facultative scavengers to carrion generated by trawl disturbance. Furthermore, there was greater food specialization in areas that were more heavily exploited by trawling. This specialisation could be linked to the availability of certain prey that results from the passage of fishing gea…
Use of stable isotope analysis to evaluate the possible impact of fish migration on a lake biomanipulation
2007
1. A lake restoration project involving mass fish removals was started to improve further the water quality of a lake recovering from severe eutrophication. The effectiveness of such biomanipulation as a lake management option could be compromised if removed fish are rapidly replaced by large-scale immigration from a connected lake. 2. Stable isotope analysis (SIA) was used to examine the migrations of perch (Perca fluviatilis L.) and roach (Rutilus rutilus (L.)) between two connected lakes in central Finland, Jyvasjarvi and the larger Paijanne. Baseline δ15N signatures in primary consumers were significantly higher in Jyvasjarvi and this difference was reflected further up the food chain i…
