Spanish scientific community in the initial assessment and management of the
environmental damages caused by the Prestige oil spill. Marine Policy (in press, May 2005). [pdf]

The role of the Spanish scientific community in the initial
assessment of the environmental and socioeconomic damages caused by the Prestige
oil spill is analyzed. A discussion of the reasons for the failures in the
response of the scientific community is presented, highlighting that despite
the existence of adequate human capital and infrastructures, failures were
related to the weakness of the structures and organisational capacity of the
scientific institutions and the public administration. Some developments for an
effective response to future catastrophes are proposed: 1) oceanographic and
ecological models, including scientific and local knowledge; 2) management
systems for scientific information; 3) organisational and incentive systems to
allow the creation of temporary, large and well-organised multidisciplinary
teams; 4) protocols for rapid, “real-time”, damage assessments; and 5)
participation of different social groups (NGOs, fishers’ organisations,
aquaculture industry or volunteer groups) in plans for the assessment and
management of crises.

Pesca artesanal y comercialización (Cuadernos de Antropología)

La pesca artesanal en Galicia
tiene una enorme importancia social, económica y cultural. No obstante, en ella
se dan una serie de problemáticas de carácter estructural que la hacen
vulnerable. La situación de la comercialización de los productos pesqueros de
la pesca artesanal agrava los problemas anteriores desestructurando al sector,
perjudicando a los pescadores y a la viabilidad futura de sus órganos de
gestión (Cofradías). En esta ponencia se presenta una solución que hasta la
fecha ha corregido y mejorado este estado de cosas mediante la puesta en marcha
de una iniciativa empresarial pensada para minimizar estos problemas. Esta
iniciativa se llama Lonxanet y en la que seis cofradías gallegas están
integradas actualmente.

Plankton and larval fish dynamics (Prog. Oceanogr.)

Franco-Gordo C, E Godínez-Domínguez, AE Filonov, IE Tereshchenko & J Freire (2004). Plankton and larval fish dynamics prior and during El Niño period (1997-98) in the central Pacific coast of Mexico. Progress in Oceanography 63:99-123. [pdf]

The temporal and spatial distributions of zooplankton biomass and larval fish recorded during 27 months (December 1995–December 1998) off the Pacific coast of central México are analyzed. A total of 316 samples were obtained by surface (from 40–68 to 0 m) oblique hauls at 12 sampling sites using a Bongo net. Two well-defined periods were observed: a pre-ENSO period (December 1995–march 1997) and an ENSO event (July 1997–September 1998) characterized by impoverishment of the pelagic habitat. The highest biomass concentrations occurred at coastal stations during the pre-ENSO period. During the El Niño period no spatial patterns were found in coastal waters. The months with highest biomass were those in which the lowest sea surface temperature (SST) occurred (January–May), and this pattern was also observed during the ENSO period. A typical, although attenuated, seasonal environmental pattern with enhanced phytoplankton (diatoms and dinoflagellates) was prevalent during the El Niño event in nearshore waters. During the El Niño period the phytoplankton was mainly small diatoms (microphytoplankton), while dinoflagellates were practically absent. The most parsimonious generalized linear models explaining spatial and temporal distribution of larval fish species included the ENSO index (MEI), upwelling index (UI) and distance to the coast. The environmental variability defined on an interannual time-scale by the ENSO event and the seasonal hydroclimatic pattern defined by the UI (intra-annualscale) controlled the ecosystem productivity patterns. The small-scale distribution patterns (defined by a cross-shore gradient) of plankton were related to the hydroclimatic seasonality and modulated by interannual anomalies.
