    ABSTRACT Whika Febria Dewatisari. 2007. THE INFLUENCE OF NAUPLII DENSITY WITH FEEDS FRINGESCALE FISH SILAGE TO BIOMASS PRODUCT OF Artemia franciscana. Biologi Departement. Faculty of Mathematic and Natural Sciences. Sebelas Maret University. Surakarta. Artemia franciscana (Anostraca, Artemidae) is low level of Crustacea which was usually used as natural feeds in fish and shrimp larva culture especially for cultivation efforts. Nauplius (A. franciscana new hatch) contains sufficient high protein which is good in growing the fish and shrimp larva. By expanding Shrimp cultivation it will almost always increasing the requirement of A. franciscana. In generally cultivation A. franciscana can be developed using only the cheap equipments and simple techniques, although the benefit of the activities would be quite a lot. Many factors should be considered very carefully in order to make the cultivation activities successfully. For example how to feed the A. franciscana with the highest protein contained such as silage of fish and how the density of the fuse silage should be distributed. The aim of the Research were to know (1) the growth and survival rate of A. franciscana with the gift of Fringescale fish silage in various density (2) the optimal density in the best of growth and survival rates of A. franciscana. The methods used in this research was used Complete Random sampling, and done with in 14 day using 6 kinds of treatment and 3 restating. Nauplius disperse into conservancy media (salinity 80 g / l) with the density 500, 800, 1100, 1400, 1700 nauplii / litre with the dose of fish silage as much 30 mg / l. For the treatment of control was given the coconut cake as much 30 mg /l, nauplius disperse with the density 500 nauplii / l. The parameters measured were growth, survival rate, specific growth rate, feed convertion ratio, dry and wet A. franciscana biomass conducted in the end of research. Quality of water measured everyday were salinity, temperature, pH while for the amonia measured in each three-day once. The obtained data were analyzed by using variance analysis (ANOVA) and continued with Tukey Test. The result showed that the treatment in density 500 nauplii / l have survival rate 78 % and growth ( heavy and length) highest that is 6,941 mg and 1,6346 mm, and also have the highest spesific growth rate 0,3826 mg / day. Optimal density there are in density 1100 N / l productively the best of feed conversion ratio 1,127 % and highest biomassa equal to 7,7329 g with 62 % survival rate.
