Judul: Study of the Temperature and Food Source Effect on Development and Reproduction Model of the Cyclopoid Copepod Apocyclops sp. That Individual Cultured in the Laboratory at Different Temperature and Food Source
Abstrak: Research on copepods Apocyclops sp. have been conducted since 1996 by the UNSRAT’s Faculty of Fisheries and Marine Science. The research focused more on the bioecology and reproduction characteristics. Former researchs reports a high quantity of eggs produced by the copepods Apocyclops sp. Its lifespan can reach a total number of 70 to 448 with three to four times of copulations. The research is aimed at finding out the difference effect of temperature and feed source on structure and some reproduction charactheristic of Apocyclops sp.. The copepod is individually cultured in the laboratory. Observation is focussed on the biological reproduction aspect. Variables measured include : total fecundity, intercluth, hatching ratio, copulation rate, reproduction intervals, sex ratio. The research uses experimental design to measure the effect of temperature, and food conditioned and the obtained data are analized by the ANOVA and continued by Duncan’s Multiple Range Test. The result showed that the interaction of temperature and microalgal food give no significantly different to fecundity, hatching, and growth stadia; and significantly different to intercluth, copulation, generation time, sex ratio, and age, the temperature give high significantly different effect to total fecundity, hatching, hatching ratio, intercluth, generation time, copulation, sex ratio, age, and growth stadia. Giving of microalgal Chlorella sp., Tetraselmis sp., and Nannochloropsis oculata give high significantly different effect to whole of variables measured.

Abstrak: Supply of mud crab depand on nature stock because crab culture activities and cultivation technology is still limited, so that the exploitation of natural crab was in uncontrolled. In addition, the high mortality due to cannibalism is still the dominant factor affecting the maintenance of mud crab production, both in the larvae and post-larvae stage. A research aimed to examine the effect of temperature on the survival rate and growth rate of mud crab. The research had been done on April 2014 in the Laboratory of Aquatic Animal Physiology, Faculty of Fisheries and Marine Science, Bogor Agricultural University. The treatments consisted of the temperature medium 25±0,21oC (A), 27±0,15oC (B), 29±0,21oC (C), and 31±0,21oC (D). The mud crabs measuring of 90±2,02 g/fish were reared in an container with circulation system with a density of 8 fish/container during 28 days. The results showed that the mud crab were reared on different temperatures had a significant effect (p <0.05) on the survival rate and growth rate of mud crab. The temperature of 29±0,21oC was the optimum temperature for mud crab.
