Effect of water movement on the growth of Gelidium robustum (Gardn.) Hollenb. and Abb. (Rhodophyta) (in Spanish & English

Abstract

The growth of the red alga G. robustum was measured in situ and in cultivation tanks under different current and agitation velocities. The hypothesis that growth of G. robustum increases from the effect of water movement over the plant was tested. It was demonstrated in situ that zones with greater water movement stimulated the growth of G. robustum. Growth was directly proportional to water movement under semicontrolled cultivation conditions. The treatment with the greatest dynamics demonstrated a growth of 3.6% day-1, which is greater than the previously registered maximum for this species. -Authors
