| As a contribution to the biological knowledge about the sea fan Gorgonia ventalina and the use of this information as a tool to generate conservation and management strategies for this threatened species, a study about its annual growth rate, in different reef areas in Santa Marta and the National Natural Park Tayrona in the Colombian Caribbean took place. Manual measurements of 35 colonies were analyzed and images of 11 colonies were recorded in the beginning and in the end of the field stage. The annual growth rate varies among colonies and areas where measurements were taken. The average annual growth rate obtained with both of the methods was high and oscillated between 7.6 and 8.1 cm/year in height and between 6.9 and 8.3 cm/year wide. The total area... |

| In order to identify initial factors that can affect shrimp postlarvae survival during larval rearing, three larval rearing facilities from the Caribbean coast of Colombia were samplesd for 71 nauplii batches during 10 months of 1996. For each batch, cualitative variables (origin, transportation mode, presence of bacteria in transport water) and quantitative variables (transportation time and density, physicochemical parameters of the water, proportion of each nauplii stage and of deformed nauplii) were monitored. Water quality and density (nauplii/l) variables were monitored during the whole process of nauplii packing, transport, reception, acclimatization and stocking. To evaluate the relationship between qualitative variables and larval rearing... |

| Se realizó un cultivo piloto de macroalgas en bahía Portete, La Guajira, Colombia, entre julio de 2005 y junio de 2006, con el fin de evaluar la factibilidad de implementarlo como alternativa productiva para las comunidades costeras de la región. Se sembraron 114 kg de las algas rojas Gracilaria cervicornis, Hydropuntia cornea, Hypnea musciformis y Grateloupia sp. sobre cuerdas de polipropileno y mallas cilíndricas en dos lugares de la bahía. La especie G. cervicornis tuvo tasas de crecimiento relativo (TCR) entre 0.1 % día-1 y 1.22 % día-1, con promedio de 0.44 % día-1, fuerte epifitismo y altas tasas de pérdida. La especie H. cornea presentó un promedio de TCR de 0.91 % día-1 y osciló entre 0.02 % día-1 y 3.5 % día-1 en el sitio uno, mientras que en el... |
