Abstract

Abstract Shell is aquatic organism class of Molluscs as non selective filter feeder and also as seafood main menu. In other side many food poisoning case was found as result consuming of Shell. Timbale (Pb) is one of very dangerous heavy metal and able to caused of poisoning in organism. According to PP RI Number 82/2001 Pb concentration that was suitable with maximum limit of aquatic quality is 0,03 ppm. Sargassum sp. also was knowned have been absorbing ability for heavy metal like Pb that spread in aquatic. Hopeable with a Sargassum sp. as biocontroll model on timbale heavy metal contens is able to prevent food poisoning causing contaminated shell consumtion. This research was done in Fisheries Laboratorium Fisheries and Marine Faculty Airlangga University on 15th – 11th 2010. The research method is experiment with design of experiment that used is Completely Randomized Design Factorial with three replicates (I, II and III) and consist of two factors, that is Pb(NO3)2 in concentration 0.015 ppm, 0.03 ppm and 0.06 ppm, Sargassum sp. in weight 100 g, 200 g and 400 g. Data analysis using Analysis of Variance (ANOVA), if there are any different it could be continued with Honestly Significant Difference (HSD) Test to known interaction between treatments. Result of the research indicates that Pb dose is significantly (p<0.05) to Pb contens number that absorp by Sargassum sp. among research. It's supported by HSD test indicates that highest result is A3 (Pb(NO3)2 0,06 ppm) that significantly with A2 (Pb(NO3)2 0,03 ppm) and A1 (Pb(NO3)2 0,015 ppm). Sargassum sp. is also be able to used as biocontroll to timbale heavy metal contens that absorbed by shell, because in low and highest dose Sargassum sp. absorption capacity to the timbale always bigger than shell absorption capacity . In other side, there are no interaction between timbale dose and weight of Sargassum sp. to timbale contens that absorbed by shell.

Abstract

AbstractGrouper (Cromileptes altivelis) is a kind of coral reef fish that only lives and grows fast in tropical areas. The grouper fish (Cromileptes altivelis) is one of high economy value sea fishes. One of the ways to increase the grouper fish (Cromileptes altivelis) production is by enhancing the feeding management. The energy feeds are the ones containing high energy. High energy is able to improve the feeding efficiency and the increasing weight of grouper fish (Cromileptes altivelis) and to reduce the water contamination. The research is aimed to know the influence of the different feeding energy to the growth rate, feed efficiency, fat content and the survival rate of grouper fry (Cromileptes altivelis). The research method used in this one was the experiment and the applied design was Complete Random Design (CRD) with 5 treatments. The treatments were A (3.263,92 kkal/kg) as controller, B (3.291,59 kkal/kg), C (3.330,62 kkal/kg), D (3.453,35 kkal/kg), E (3.535,35 kkal/kg) and every treatment was repeated four times. The obtained data were analysed by using Analysis of Variance (ANOVA), if there were differences, it will be continued with the Duncan Multiple Range Test (DMRT). The research showed that the daily growth rate, the feed efficiency, the fat content and survival rate of grouper fry were the same respectively (p>0.05).

Abstract

AbstractThe aim of this research was to find out optimum percentage of given fermentation the prawn waste flour in artificial feed on growth of black nile tilapia. The treatment of this research was giving fermentation the prawn waste flour in artificial feed i.e. 0%, 2,5%, 5%, 7,5%, 10%. Each treatment was repeated 4 times. Feed compositon was made of isoprotein. Fishes weight were about 6.1 – 6.8 g. Fishes were cultured with stocking rate 3 fish per 20 liter water and the fishes were reared for 40 days. Feed amount that consumed by fishes was measured every day to calculate feed conversion ratio. The calculation of fishes amount was done in beginning and end of research to count survival rate of fishes. Water quality was measured on beginning, middle and end of research. The design of this research was Completely Randomized Design. Data analysis used Analysis of Variance (ANOVA) to know the effect of the treatment and that difference among the treatment used Duncan's Multiple Range Test (DMRT). The result of the research showed that the highest growrth rate were attained on feed containing 10% of fermented prawn waste flour. The best feed convertion ratio were attained on feed containing 10% of fermented prawn waste flour.

Abstract

Abstract Daphnia magna has good nutrition to carry on egg produce and fry of fish cupang, maskoki, oscar, tetra, and also can used for food source of fry and seed. Daphnia magna not only supply from natural environment, cause their growth deppend on fertilizer as food and environment condition. The other side: high population density, limited of food source low temperature and shorter irradiation can produce dorman egg (ephippia). The dorman eeg can use for Daphnia magna stock which way by hatching. The factor that can be influence for ephippia hatch are temperature and density. Based on this fact, a research about influence of different temperature and ephippia density for ephippia hatch of Daphnia magna. The purpose of this research was to know the influence of different temperature and ephippia density for ephippia hatch of Daphnia magna. This research has experimental characteristic and use Factorial Completely Randomized Design with three experiments of temperature (A factor), three experiments of density (B factor) and three times replicated. There are 9 kinds of combination between density and temperature. The parameter which checked in this research is degree of hatch of ephippia Daphnia magna and water quality that is dissolve oxygen rate, NH3 and of pH hatch media. The result of the analysis showed that the temperature and density influence of hatching Daphnia magna ephippia. The best result can be used for hatching Daphnia magna ephippia is temperature at 25oC with density 50 ephippia /100 ml giving highest result for the hatch of ephippia Daphnia magna. There are interaction betwen temperature and density for hatching.
