EPIFIT PADA RUMPUT LAUT DI LAHAN BUDIDAYA DESA TUMBAK
ABSTRACT: The purpose of this
research was to identify the types of epiphyte that attach to seaweed in
cultivation area of Tumbak Village, Posumaen District, Southeast Minahasa
Regency. Identifications were done
directly in cultivation site owned by farmers and in Laboratory of Aquaculture Technology,
Faculty of Fisheries and Marine Science Sam Ratulangi University. Observations were conducted three times at
two weeks interval. Weight of seaweed
was measured to obtain data of daily growth rate. In addition, water quality was also measured
in situ including dissolved oxygen, pH, temperature and salinity.
Research result found there were
three species of epiphyte attaching on seaweed K. alvarezii including Ulva reticulata Forsskal, Dictyota
dicotoma (Hudson), and Achanthophora spicifera (J. Agardh). Seaweed tested was still clean until the end
of research period and only a few of
epiphyte was observed. This condition,
supported by good water quality during the research period, resulted in very
good growth of seaweed with a daily
growth rate achieved 4.43%.
