Several research initiatives have been undertaken to map fishing effort at high spatial resolution using the Vessel Monitoring System (VMS). An alternative to the VMS is represented by the Automatic Identification System (AIS), which in the EU became compulsory in May 2014 for all fishing vessels of length above 15 meters. The aim of this paper is to assess the uptake of the AIS in the EU fishing fleet and the feasibility of producing a map of fishing effort with high spatial and temporal resolution at European scale. After analysing a large AIS dataset for the period January-August 2014 and covering most of the EU waters, we show that AIS was adopted by around 75% of EU fishing vessels above 15 meters of length. Using the Swedish fleet as a case study, we developed a method to identify fishing activity based on the analysis of individual vessels' speed profiles and produce a high resolution map of fishing effort based on AIS data. The method was validated using detailed logbook data and proved to be sufficiently accurate and computationally efficient to identify fishing grounds and effort in the case of trawlers, which represent the largest portion of the EU fishing fleet above 15 meters of length. Issues still to be addressed before extending the exercise to the entire EU fleet are the assessment of coverage levels of the AIS data for all EU waters and the identification of fishing activity in the case of vessels other than trawlers.

The fishing sector is a candidate for efficient climate policies because it is commonly exempted from greenhouse gas taxes and the fundamental problem of using a common pool resource is far from optimally solved. At the same time, fisheries management has other objectives. This study uses Swedish fisheries to analyse how the fishing sector and its climate impact are affected by regulations aiming at: (1) solving the common pool problem (2) taxing greenhouse gas emissions and (3) maintaining small-scale fisheries. The empirical approach is a linear programming model where the effects of simultaneously using multiple regulations are analyzed. Solving the common pool problem will lead to a 30 % reduction in emissions and substantially increase economic returns. Taxing greenhouse gas emissions will further reduce emissions. Policies for maintaining the small-scale fleet will increase the size of this fleet segment, but at the cost of lower economic returns. However, combining this policy with fuel taxes will reduce the size of the small-scale fleet, thus counteracting the effects of the policy. If taxation induces fuel-saving innovations, it is shown that this will affect not only emissions and fleet structure, but also quota uptake.

In the wake of the crisis for commercial fisheries, the possibility to support and develop economic activity from recreational fishing has gained increased political interest in Sweden. Promoting management actions that facilitate development of the industry requires knowledge about the current structure of the industry and companies' views regarding future challenges. We address these topics using data from a mail survey sent to companies that derive at least part of their income from the Swedish recreational fishing industry. In total, the survey estimates that Sweden has approximately 1,300 companies in the industry with total revenues of 500 million SEK (€1 ≈ SEK 9). The primary services provided by these companies include food and accommodation, guiding, boats, and access to fishing sites. A majority (about 55%) of the companies expect revenues to increase over the next 3 years, but still face a number of challenges to continued future development. Most significant are high labor costs, lack of large specimens of fish, lack of fish, marketing, and obtaining bank loans. The most preferred management actions were help with marketing and improved fisheries management.

An extended version of the discrete choice contingent valuation method for valuation of angling site attributes is considered in this paper. The respondent is asked to choose among existing angling sites and a described hypothetical site. A new contribution is the approach suggested for modeling this kind of data where hypothetical alternatives are compared with existing ones. A major advantage of this new modeling approach is that it avoids the substantial need for information on existing angling sites. Results from an application of the method and the modeling approach are also presented.
