This study examines Colombia's legal framework for marine conservation, focusing on its historical developments and progress toward international conservation goals. It analyzes Colombia's unique approach to creating protected areas, beginning with land-based conservation in the late 1960 s and later expanding to coastal and marine areas to evaluat...
La Constitución política colombiana de 1991 estableció una serie de mecanismos jurídicos a través de los cuales los ciudadanos son llamados a ser partícipes en los procesos de toma de decisiones tales como las consul-tas populares, consulta previa, veedurías ambientales y otras. Estos meca-nismos han venido siendo implementados mediante un proceso...
Territorios líquidos de Colombia. Espacios marítimos e insulares ante la legislación nacional e internacional
Colombia cuenta con un inventario de 31702 humedales, de los cuales el 20% se
encuentra en áreas con algún tipo de protección jurídica, algunos catalogados como
espacios de importancia ecológica internacional, otros declarados reserva de la biosfera
o se ubican en las zonas marino-costeras de acuerdo a la clasificación RAMSAR,
acogida en la legisla...
Aguas marinas. Evolución histórico-legislativa de los procesos de concesión
Consultora independiente. Barranquilla, Colombia Resumen Colombia es un país que cuenta con una abundante oferta de recursos hídricos. Sin embargo, esta oferta está condicionada por las características climáticas del territorio y diversos fenómenos oceánico-atmosféricos (El Niño / La Niña). Esta disparidad de condiciones compensa períodos excesivos...
The vertical distribution and vertical migrations of fish larvae and implications for their cross-shelf distribution were investigated in the northern limit of the NE Atlantic upwelling region during the late winter mixing period of 2012. The average positive values of the upwelling index for February and March of this year were far from normal, al...
This study evaluated potential differences in morphology of unextruded larvae from Sebastes mentella and Sebastes norvegicus in Icelandic waters. Fifty-four larvae of each species were measured, and 18 measurements were recorded for each specimen (morphometric, meristic and pigmentation patterns). Pre-extrusion larvae of S. norvegicus were longer t...
The spatial stock complexity of marine fish species requires that population structure is taken into account in fisheries
management. The aim of this study was to determine whether the amino acid composition (AAC) of the adult fish allows the identification
of subpopulations within the stock. During a cruise in November 2003 along the entire Medite...
Knowledge on early ontogeny of Trisopterus luscus is scarce and incomplete. This paper describes the first successful attempt ever at achieving the natural spawning in captivity for this species. The reproductive specimens used for this study were obtained in the Rı´a de Vigo in September 2008 and subsequently transported to the facilities of the I...

The aim of this study was to identify the factors responsible for the differences in chlorophyll a concentration (Ch1-a) observed between the California, Canary, Humboldt and Benguela upwelling areas. Monthly climatologic values of Ch1-a obtained from satellite images, covering the years 1998-2004, revealed that this pigment was higher in the Bengu...
This study focuses on the interactions between toxic phytoplankton and zooplankton grazers. The experimental conditions used are an attempt to simulate situations that have, so far, received little attention. We presume the phytoplankton community to be a set of species where a population of a toxic species is intrinsically diverse by the presence...
The aims of this study were to describe the reproductive cycle of the European anchovy (Engraulis encrasicolus) off the south coast of Sicily and determine whether intra- and inter-annual reproductive trait variations, if any, are adaptive responses which maximize reproductive success under environmental fluctuations. Biological data were collected...
Egg and larval abundance, obtained from annual summer cruises carried out in the Strait of Sicily during 6 years (1997 to 2002), was used to identify the spawning and retention areas of the anchovy Engraulis encrasicolus. Larval amino acid composition was used to analyse the nutritional condition of the larvae collected during the 2002 survey. As t...
The aim of this work was to study the influence of bacterial epiflora on egg hatching of the sardine (Sardina pilchardus) obtained from a natural environment (Ría de Vigo, Spain) during the spawning season of the sardine (from January to June). Total bacteria, viable bacteria or the presence of specific potential pathogens for eggs, such as Pseudoa...
Positive parental effects, defined as the strategies displayed by sardine Sardina pilchardus adults to increase the survival of eggs and larvae, were studied off the coast of the Iberian Peninsula (Spain) by monthly sampling of eggs and larvae in Ría de Vigo, over a period of 4 yr. Two different parental strategies were observed over the spawning p...
Climatic warming is affecting oceanic circulation patterns in coastal upwelling areas, but the impact of this climatic change on pelagic fish populations remains unclear. From juvenile landings collected over 38 years, the thresholds of environmental factors were determined that limited the optimal environmental window (OEW) for sardine (Sardina pi...
Several aspects of anchovy reproductive biology were assessed over a six-year period from commercial landing data from the main spawning ground of the anchovy population off the southern coast of Sicily. This work represents the first attempt to investigate the reproductive features of the anchovy population in this area. The intra-annual and inter...
We analysed the amino acid composition (AA) of eggs and larvae of the pelagic fish species Sardina pilchardus (sardine), Scomber scombrus (mackerel), Trachurus trachurus (horse mackerel) and Micromesistius poutasou (blue whiting) collected along the west Atlantic coast of Spain and from the Cantabrian Sea during March to April 2000. A discriminant...
The fate of paralytic shellfish poisoning (PSP) toxins ingested by the copepod Acartia
clausi was studied in unialgal and mixed cultures of the toxic dinoflagellate Alexandrium minutum
and the non-toxic dinoflagellate Prorocentrum micans. Acartia clausi fed actively on Alexandrium
minutum, but feeding pressure diminished over time. This reduced fee...
Unialgal and mixed cultures of the toxic dinoflagellate Alexandrium minutum and the non-toxic dinoflagellate Prorocentrum micans were cultured under phosphate (P) limitation (<1 muM), in the presence or absence of the copepod Acartia clausi. The aim was to determine the possible effects of interspecific competition, predation and nutrient limitatio...
The aim of this study was to determine how climatic (North Atlantic Oscillation winter index, NAO, December through March), oceanographic (upwelling intensity, turbulence, water column stability and larval offshore transport) and biotic (adult abundance) factors affect recruitment success of Sardina pilchardus off the northwest coast of the Iberian...
