The study determined the ecological conditions of the seaweed farming site in terms of salinity, light penetration, temperature, substrate, water depth, water current and biotic factors; measured the biomass production in control and experimental; determined the significant difference in the biomass production between the control and experimental groups; and determined the significant relationship between the biotic factors and biomass production. The independent variable of the study was the ecological factors; the moderator variables were the control and experimental groups and the dependent variables were the biomass production. It employed the experimental research methodology. The physical parameters were monitored weekly while the biotic factors were monitored daily up to 30 days. It was conducted in barangay Magsaysay, Lavezares, Northern Samar. Findings of the study revealed that the ecological conditions of both the control and environmental group were favorable to the seaweed far in terms salinity, light penetration, temperature, substrate, water depth and water current. However, the results of the study revealed that among the ecological factors considered, the biotic factors had influenced most on the cultured seaweeds particularly on the experimental group with harmful effects. In terms if biomass, data showed that the control group exhibited production while the experimental group had non because of the effects of biotic factors. There was a significant difference in the biomass production of the control and experimental groups because comparatively, only the control group registered biomass production and significant relationship between the biotic factors and biomass production of the seaweeds. The more grazers in the seaweed farm, the lesser the biomass produced. The conclusion arrived to was that cultured seaweeds in farm sites should not be “caged” because by so doing the cage serves as a sanctuary for grazers particularly siganids and enable some algae and epiphytes to grow that trap the nutrients brought about by the water current. Furthermore, when these events occur, eventually “ice-ice” disease will attack the seaweed.
