Abstract

DAISY WOWOR. 1985. Population structure and spawning period of Udang Regang (Macrobrachium sintangense). BeritaBiologi 3(3): 116- 120. Population structure and spawning period of Macrobrachium sintangense was observed in a coast of a small artificial lake, Situ Ciletuh, Ci gombong, West Java, from December 1981 to August 1982. Examination of the class-size frequency indicated the growth rate of body length of the population, and its spawning periods.The mean growth rate of carapace was 3.44 mm per month.Sex ratio was 1:1, significant at the 95% level. The number of the larger males is greater than the females, which indicate the phenomenon of sexual dimorphism.This is due to the differences of growth and the maximum body size attained by the males and females. It was observed that M. sintangense spawns throughout the year, maximum spawning activity occurs between March and June.

Abstract

Salah satu problem utama dalam pemeliharaan kadang ialah pemenuhan kebutuhan akan makanan tambahan bagi pertambahan laju pertumbuhan iLing 1972, Willis et al 1976, Suharto 1977) yang efisien.Makanan tambahan tersebut dapat berupa cacahan daging, makanan kering atau bentuk-bentuk lainnya. Mulai awal September 1979 sampai dengan pettengahan November 1979 telah diadakan pengamatan terhadap laju pertumbuhan udang regang Macrobrachium sintangense (de Man) yang diakibatkan karena pemberian tiga macam makanan buatan yang dibuat dari bahan makanan yang sederhana.Udang tersebut adalah udang air tawar yang umum dijumpai dan dapat dipelihara di akuarium tanpa banyak mengalami kesukaran dan perlakuan (Sabar, 1979).
