Abstract

YUN INDIARTO.1988,Relationship between percent coverage of Salvinia molesta f nd growth rate of Nile Tilapia (Tilapia nilotica),Berita Biologi 3(8) : 400 - 404.A study on the growth rate of Nile Tilapia in relation to various coverage of S.molesta has been conducted in experimental ponds for twelve weeks. Anaiysis of variance shows that the percent coverage of S.molesta affected significantly the growth rate of the Nile Tilapia (weight : F>F 0.01 and length : F > F0.05).It was found that 50% coverage or more may reduce the tish growth rate.The best growth rate was 1 reached at 25% coverage.Environmental condition:related to the above findings are discussed.

Abstract

YUN INDIARTO, MULYADI & RAZALI YUSUF, 1989.The structure and composition of mangrove in Bikoen-Kupang,Timor.Berita Biologi 3(9): 455 - 457.Mangrove forests in EastNusa Tenggara cover a total areas of about 1930 ha(Darsidi, 1984). Little is known about the mangrove forest in that island, especially in Bikoen, Kupang Region.Therefore, the study has been conducted at the mangrove forest of Menipo Nature Reserve in order to analyse the structure and composition of the species.Four transects perpendicular to the coast line were used for data collection.At least, there were 12 mangrove species found in the forest, dominated by Ceriops tagal, Rhizophora stylosa and Bruguiera exaristata. Seedlings dominated the forest by 49,92%, where as the sapling were 45.43%.
