Game and experimental theorists have specified the conditions under which different auction systems may lead to distinct price levels. By changing the sales organisation, the introduction of electronic auction systems on first-hand fish markets is expected to have modified bidders' habits, hence affecting the price levels. A demand model based...
There has been significant growth in the catches of bluefin tuna in the Atlantic Ocean and especially in the
Mediterranean Sea for the last decade due to the expansion of fattening farms which export their production to
Japan. There has been an increase in catches due to strong demand and,...
Some recent studies have shown the outstanding price linkages at the global scale between the cannery-grade
tuna markets over the last decade. When it comes to price transmission along the European value chains, opposite results between the two major species (skipjack and yellowfin) are found: the market for final goods...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
This paper studies the price volatility transmission between the different markets along the value chain of fresh anchovy (Engraulis encrasicolus) in Spain. For this purpose, the prices at the ex-vessel market, the wholesale market and the retail market are considered. As a methodology, a Vector Autoregressive Model (VAR) and an...
Fisheries management involves considering several biological, economic and political objectives. They are often contradictory. For this reason, it is almost impossible to reach them simultaneously. Andalusian regional government collaborates with the national government to establish fishing plans for local fisheries. The objectives of these plans verify the aforementioned statement. For...
In this paper we analyse different econometric procedures of technical efficiency to estimate fishing capacity. These procedures are then applied to the purse seine fishery located in the Gulf of Cádiz. The target species of this fishery has changed quite a lot over the past few years. It used to...
Circle hooks have been promoted as an alternative to traditional J-hooks in pelagic longline fisheries to minimize bycatch mortality and injury to sea turtles and other marine wildlife. We evaluated the effect of hook type (circle hook vs J-hook) on the catch and length composition of target and non-target species...
Seabream is the most important farmed species in the Mediterranean region, and Spain is the largest market. A key question for this industry is to assess the way in which negotiation power is distributed along the value chain. Price transmission is studied by analyzing market integration between different levels of...
Sometimes there are movies that do more than just tell a story; sometimes they make a character come to life in such a way that the audience is profoundly moved. In this thesis I have compared and explored two movies that truly impacted my view on life. Il Postino and...
Traditionally, little attention was paid to the market and how the different levels of the market chain
interact. However, recent price developments and the increase in the retail chains’ market share have
raised awareness on the food supply chain and possible market power situations in Europe. This paper
uses 2004-2009...
A wide range of fisheries are managed using vessel catch limits combined with different kinds of effort restrictions. This management framework is expected to have desirable consequences for the bioeconomic sustainability of fisheries. When appropriately implemented this approach produces outcomes that are similar to those associated with individual fishing quotas....
Management of the Danish protein fisheries in the North Sea has during recent years become increasingly politicised, as various stakeholder groups are seeking influence on the decision-making process. In relation to management of the sand eel and Norway pout fisheries, two different issues are debated. In the sand eel fishery,...
Fisheries management is characterised by multiple objectives. However, seldomly do bioeconomic models incorporate more than one or possibly two key objectives, typically profit and employment, into an analysis. There are both practical and technical reasons for this. This study considers the incorporation of eight key objectives into a bioeconomic analysis...
When attempting to mitigate the environmental impacts of a fishery there are typically multiple criteria
against which the performance of any measures can be assessed. If the gains are non-commercial (i.e.
non-market) in nature, formally determining how well measures perform becomes more difficult. This study applies the analytic hierarchy process...
This research investigated yeast populations and diversity during pre-fermentation cold maceration and alcoholic fermentation of Vitis vinifera L. cv. Pinot noir grapes from a commercial vineyard (Dayton, OR). Fermentations were conducted at the Oregon State University research winery in 100 L tanks while grapes from the same vineyard lot were...
The Gran Chichimeca is a North American area extending from
the Tropic of Cancer to the south to the thirty-eighth parallel in
the north, thus embracing northern Mexico and the American Southwest.
The rise of the great mesoamerican civilizations to the south
of the Gran Chichimeca and the consequent pressure...
This thesis explores a three month period that I spent abroad working in medical clinics and hospitals in Ecuador. My work was conducted in three distinct areas: the urban landscape of Quito, Ecuador’s capital; Puyo, a small town bordering the Amazonian rainforest; and a small community located in the heart...

Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...
