Abstract:: Based on financial risk analysis and portfolio theory, this paper aims to estimate the underlying risk of the European fish quota distribution among European member States along the time. Firstly, we have assigned a fishing portfolio to each member state (FP(jt)) and its related value based financial portfolio (FPV(ijt)), where...

Abstract:: The main objective of this paper is to analyze the economics effects that the Prestige oil spill over (2003) had on the Basque coastal fishing industry by means of a two-stage stochastic production frontier approach. The first stage is based on the econometric specification of a parametric production frontier based...

Abstract:: A primal formulation has been used to estimate a translog production function that includes fishing effort and fisherman’s skill as production factors. The selected functional form permits the analysis of the substitution possibilities among production inputs composing effort by calculating the Allen elasticity of substitution. Particular attention is paid to...

Abstract:: In other to implement the ecosystems approach to take care of fisheries and their surrounding environment, multidisciplinary indicators are need. One of these indicators, which may be useful to measure the health of an ecosystem, is biodiversity. Thus, firstly this paper deals with defining, measuring and comparing alternative biodiversity index...

Abstract:: Time-series observations are critical to understand the structure, function, and dynamics of marine ecosystems. The Hawaii Ocean Time-series program has maintained near-monthly sampling at Station ALOHA (22°45′N, 158°00′W) in the oligotrophic North Pacific Subtropical Gyre (NPSG) since 1988 and has identified ecosystem variability over seasonal to interannual timescales. To further...
