Effects of salinity on the growth rate, morphology and water content of some Brazilian red algae of economic importance

The growth rate, morphology and water content of six species of Brazilian red algae of economic importance were studied under various salinities. The study comprises three agarophytic (Gracilaria aff. venucosa, Gracilaria sp. and Pterocladia capillacea), and three carrageenophytic algae (Meristiella...

The study comprises three agarophytic (Gracilaria aff. venucosa, Gracilaria sp. and Pterocladia capillacea), and three carrageenophytic algae (Meristiella echinocarpa, Hypnea cornuta and H. musciformis), subjected to salinities from 5 to 60‰. Al species tolerated, for the period and conditions described, a much broader range of salinities than they usually face in their habitats. All species were more tolerant to salinities above 30‰ than below this value, with maximum growth occurring between 25-40‰. Water content at the end of the experiments varied with the species, with an inverse relation in salinities above 40‰. Highest salinity values reduced branching, and lowest salinities lead to thalli bleaching. The results offer guidelines for the selection of potential areas with more adequate salinity regimes for the cultivation of the species studied. Se realizaron experimentos a diferentes salinidades para estudiar la tasa de crecimiento, morfología y contenido de agua en algas rojas brasileñas de importancia económica. El estudio comprende tres algas agarofíticas (Gracilaria aff. venucosa, Gracilaria sp. y Pterocladia capillacea), y tres algas carragenofíticas (Meristiella echinocarpa, Hypnea cornuta y H. musciformis), las cuales fueron sometidas a salinidades desde 5 hasta 60‰. Todas las especies toleraron un intervalo mucho más amplio de salinidades para el período y condiciones descritas, al que generalmente tienen en sus respectivos habitats. Las especies resultaron ser más tolerantes a salinidades por encima de 30‰ que por debajo de este valor, presentando un crecimiento máximo entre 2.5-40‰. El contenido de agua en las especies varió al final de los experimentos, con una relación inversa en salinidades por encima de 40‰. Los valores más altos de salinidad redujeron la bifurcación de éstas, y los valores de salinidad más bajos produjeron decoloración del talo. Los resultados de este estudio permiten elegir zonas de potencial para el cultivo de las especies estudiadas bajo regímenes de salinidad adecuados.
