Abstract

The optimum condition of culture media and feed diets which fit the necessities of Oithona similis life (ecophysiological) is very important for it to grow and develop in its maximum. The enrichment of O. similis feed can be done by adding fermented organic feed. Providing organic feed with optimum protein content is necessary to support the growth process and reproduction of O. similis. Osmoregulation process of water organism which is influenced by media salinity is related to bioenergetics process as the effort to use feed energy for the growth. This research aimed to examine the effect of different organic feed protein content and to determine the optimum point which may result in the best growth and egg production of O. similis in the optimum condition of culture media. The study used an experimental method with a completely random design consisting of 4 treatments and 4 repetitions each, i.e. O. similis culture with A. 25%; B. 30%; C. 35%; and D. 40% organic feed protein content. The results showed that the difference of protein content in organic feed affects the growth and production of O. similis eggs. The optimum point of protein content in the fermented organic feed is on protein content B, i.e. 30%, which resulted in the best growth performance (70.44 ± 0.43 ind.mL-1 total density, 0.213 ± 0.001.day-1 population growth rate, and 27.38 ± 0.48 eggs.ind-1 egg production.

Abstract

The purpose of this research is to evaluate Asian sea bass digestibility and growth fed with phytase dietary supplementation on soybean based fish diet. The initial weight of fish was 4.99±0.2 g with stocking density of 20 fishes per tanks reared in 80 L tank of sea water for 6 weeks. Completely Randomized Design of 50% soybean meal with phytase supplementation of 0; 500; 1,000; and 1,500 FTU kg-1 and three replication was used in this trial. Chromium oxide (Cr2O3) was used as digestibility indicator. Multivariate anova and One way anova (SPSS); linear regression (Microsoft Excel) and polynomial orthogonal (Microsoft Excel and Maple) was used to analyze the data. The results of Multivariate anova showed that phytase supplementation affect total digestibility (KCT) and relative growth rate (RGR) of asian seabass significantly (P<0.01) with phytase dose 1,000 FTU. One way anova also indicated that phytase 1,000 FTU significantly affect all parameters. Apparent digestibility coefficient (ADC) phosphorus had a very significant and dominant effect to total digestibility with R2 = 0.9669 than ADC protein and ADC fat (linear regression). KCT significantly affects efficiency of dietary protein (EPP) 30.57% and protein efficiency ratio (PER) 0.67%. EPP and PER significantly effect RGR 1.56%  day-1, simultaneously. The optimal dose of phytase supplementation is 1,220 FTU.

Abstract

This research was aimed to know the effect of different fermented organic feed on the growth performance of Oithona sp. in semi-mass culture condition. The Oithona sp. cultures were fed with mixed organic fermentation of pulp, bran and fish meal by using probiotic microbes and phytoplankton cells. There were 4 treatments and 4 replicates. Treatment A was the Oithona sp. cultured with added Chaetoceros calcitrans cells without fermented organic feed (0 g ∙ L–1 of medium culture). While B, C, and D were added with the same numbers of that C. calcitrans cells of 2x106 cells ∙ mL–1  and  0.5 g ∙ L–1, 1.0 g ∙ L–1, 1.5 g ∙ L–1 of fermented organic feed, respectively. The results showed that the dosage of fermented organic feed had significantly different effect (P < 0.05) on the growth performance of Oithona sp. culture. The best growth performance of Oithona sp. showed by adding 0.5 g ∙ L–1 of fermented organic feed, with total density of  7.09 ± 0.11 ind ∙ mL–1, population growth rate of  0.116 ± 0.002 ind ∙ d–1 and eggs production of  7.88 ± 0.93 eggs ∙ ind–1  of adult.
