Abstract

Gracilaria is the most promising seaweed in the fishery industry nowadays and can tolerate different environmental conditions. This study aimed to evaluate the specific growth rate and biomass production of Gracilaria spp. in marine water environments using different culture techniques like vertical rope, floating monoline bamboo, plastic bottles, and the half-side bamboo technique. The experiment was laid out in a randomized complete block design (RCBD), where each treatment had three replications. A one-way ANOVA was used to test if there was a significant difference among the four treatments. Results have shown that all the seaweed seedlings had 100% survival across the different treatments. The specific growth from floating-monoline bamboo techniques is 83.73 g/day (v/v) and the width of clusters is 16.78 cm/day. The vertical rope technique got the highest result in length (15.50 cm/day). The result is significant since the computed F-value was greater than the tabular value. Results showed that the floating-monoline bamboo technique was the best among four techniques used in culturing Gracilaria (Gracilaria spp.) in marine water environments. The results of the study provide highlights on the possible adoption of culture techniques to cater to the fast-growing seaweed production among fish farmers and might be supported by other future studies.
