Jenis pengaruh kepadatan alge filamen pada kegiatan budidaya eucheuma cottonii di peraian Teluk Kotania

The success of eucheuma cottonii cultivitation in the gulf Kotania , west Seram Maluku was influenced by varoius factor. one of them was the existence of filament algae. This study aims to indentify filament alge patching on the thalus E cottonii the infuence of filamen alge biomass on specific growth rate (SGR) of E cottonii in trial raft and the deferences of filament algae biomass patcing on the thalus E cottonii cultivated by local people in three differenct lacations. The first study was conducted in trial raft, then the identification anf maesurementsh of filame algae biomass patcing on the thalus and the maesurements of E cottonii biomass were performed on day 34 and 50. in the second study the identifications and measurements of filame algae biomass patcing onthe tahlus E cottonii has been done on the three diferencen lacations where E cottonii has been cultivated by local people . the result showed that lyngbia sp. was a species of filament alge faound in thalus E cottonii in which the algae patch on. The presence of filame algae on the thalus with biomassration 1.81, did not afect singnificantly on SGR of E cottonii in trial raft. Meanwhile, filament algae biomass abtained from three different lacoations showed a significant diferencen, where the filamet algae biomass in wael Vilage was the hinghest.
