Are coastal communities able to pay for the protection of fish resources impacted by climate change?

2020

Abstract The purpose of this study is to examine inhabitants’ motivation and their willingness to pay to mitigate the impact of climate change on fish resources. Willingness to pay was tested empirically using survey data from 333 inhabitants of Sciacca, a fishing community in Sicily, Italy, which has the island’s second largest fishing fleet. People’s attitudes towards climate change, their degree of involvement in the issue, and their concerns about this phenomenon’s potential impact on the marine environment are the key factors affecting their willingness to pay. It was further found that respondents are willing to pay an average of €6.81 per month to support mitigation policies in the f…

Identifying small pelagic Mediterranean fish schools from acoustic and environmental data using optimized artificial neural networks

2019

Abstract The Common Fisheries Policy of the European Union aims to exploit fish stocks at a level of Maximum Sustainable Yield by 2020 at the latest. At the Mediterranean level, the General Fisheries Commission for the Mediterranean (GFCM) has highlighted the importance of reversing the observed declining trend of fish stocks. In this complex context, it is important to obtain reliable biomass estimates to support scientifically sound advice for sustainable management of marine resources. This paper presents a machine learning methodology for the classification of pelagic species schools from acoustic and environmental data. In particular, the methodology was tuned for the recognition of an…

Impact of Fermentation on the Recovery of Antioxidant Bioactive Compounds from Sea Bass Byproducts

2020

The aim of the present research was to obtain antioxidant compounds through the fermentation of fish byproducts by bacteria isolated from sea bass viscera. To that purpose, bacteria from sea bass stomach, intestine, and colon were isolated. With the selected bacteria, growing research was undertaken, fermenting different broths prepared with sea bass meat or byproducts. After the fermentation, the antioxidant activity, phenolic acids, and some proteins were evaluated. The main phenolic acids obtained were DL-3-phenyl-lactic acid and benzoic acid at a maximum concentration of 466 and 314 ppb, respectively. The best antioxidant activity was found in the extracts obtained after the fermentatio…

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…

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 …

What are the effects of sea warming on the fishing industry?

2019

The paper analyses the impact of Mediterranean Sea warming on some species of small pelagic fish (pesce azzurro) in the Italian fishing industry. In particular, through a time series regression model, the research examines the productivity trend in physical terms of target species of small pelagic fish from 1950 to 2016, considering the Mediterranean Sea Surface Temperatures Anomalies as an indicator of sea warming, and the Western Mediterranean Oscillation index and the North Atlantic Oscillation index as proxies of climatic variability. The research results show an evident link between the reduction of fish availability and sea warming, with potential repercussions on the incomes of the e…

Ranking of small scale proposals for water system repair using the Rapid Impact Assessment Matrix (RIAM)

2014

Abstract Environmental impacts of small scale projects are often assessed poorly, or not assessed at all. This paper examines the usability of the Rapid Impact Assessment Matrix (RIAM) as a tool to prioritize project proposals for small scale water restoration projects in relation to proposals' potential to improve the environment. The RIAM scoring system was used to assess and rank the proposals based on their environmental impacts, the costs of the projects to repair the harmful impacts, and the size of human population living around the sites. A four-member assessment group (The expert panel) gave the RIAM-scores to the proposals. The assumed impacts of the studied projects at the Easter…
