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...
This paper is aimed at studying the relationship between marine environmental conditions and purse seine anchovy fishery of Alboran Sea through a stock-recruitment model using an historical data set of anchovy fishery in the Northern Alboran Sea that covers two decades from 1985 to 2005 and the HadISST and Era...
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,...
Anchovy fishery of Georgia (North Eastern Black Sea) has experienced a
considerable decline since the 80ths. The Ministry of Environment
Protection and Natural Resources (MEPNR) is in charge of fisheries
management since 1994 and is implementing since late 2006 a new
licensing system based on auction concept. According this management...
The valuation marine ecosystem services have been receiving increasing attention in scientific literature, however most of the research is focused in marketed services and does not consider the part of the total economic value. Some services like cultural services that are not direct (touristically) or indirectly marketed as part of...
This paper is aimed at determining the impact of the variability of marine environment conditions on the
capture of a vessel that exploit the red seabream fishery of the Strait of Gibraltar. This paper estimates
first and second order elasticities of a Translog approximation of a Stochastic Distance Functions of...
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...
Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...
