Abstract

Abstract This study aims to determine the effect of Nata De Nanno and Nannochloropsis oculata for Brachionus plicatilis population. The research method used was experimental with a Completely Randomized Design (CRD) with six treatments and four replications. The treatments used were: (A) Nata de Nanno 5x109 cells/L N. oculata, (B) Nata de Nanno 4x109 cells/L N. oculata, (C) Nata de Nanno 3x109 cells/L N. oculata, (D) N. oculata 5x109 cells/L, (E) N. oculata 4x109 cells/L and (F) N. oculata 3x109 cells/L. Analysis of data using variant analysis (ANOVA) and to determine the differences between treatments performed tests Distance Regression Duncan. The results showed that administration of Nata De Nanno and Nannochloropsis oculata for Brachionus plicatilis populations exert a significantly different (p<0,05) in each treatment delivery Nata De Nanno and Nannochloropsis oculata with the highest peak population of young B. plicatilis achieved on the fifth day of treatment D (N. oculata) with a concentration of 5x109 cells/L produce a population young B. plicatilis as much as 98,5 individuals/ml. The lowest peak population of young B. plicatilis on the fifth in treatment C (Nata de Nanno) with a concentration of 3x109 cells/L N. oculata 76,75 produce a population of young B. plicatilis 76,75 individuals/ml. Water quality parameters during the study was the temperature ranges between 27-31°C, a salinity of 31 ppt, pH value 7, DO (Dissolved oxygen) ranged between 5-8 mg/L, and ammonia levels ranged from 0-0.25 mg/L.

Abstract

Abstract One type of phytoplankton that are used in marine fish hatchery activities namely Nannochloropsis oculata. The purpose of study case is to know patterns growth of N. oculata in culture scale laboratory, intermediate, and bulk. Study was held in Situbondo Brackishwater Aquaculture Center of East Java in January-February 2011. Study case methods used is descriptive method. N. oculata culture techniques performed by multilevel methods, beginning with the isolation of phytoplankton in the media for/liquid, culture in test tubes 10 ml and elenmeyer 50-100 ml, culture on the bottle 100-1000 ml, culture in karboy of 20 liters, intermediate scale culture 100 - 1000 liters and a mass-scale culture with a volume of more than 1000 liters. Laboratory-scale use Walne for fertilizer. Intermediate-scale use of fertilizers FeCl3 1-2 ppm, 10 ppm EDTA, Na2HPO4 10-15 ppm, 100-150 ppm KNO3, and Tracemetals/vitmix 5 ml/m3, mass-scale culture use of fertilizers FeCl3 1 ppm, 5 ppm EDTA, TSP 20 ppm, ZA 40 ppm and 50 ppm urea. Water quality measurement results obtained by laboratory scale temperature is 23 - 25°C, intermediates and mass scale is 30°C, pH in the culture laboratory scale and intermediate is 7.7 to 7.8, mass culture pH is 7.9, salinity laboratory scale 29-30 ppt, intermediates and mass scale 30 ppt. During mass culture of N. oculata showed that the growth pattern in accordance with the general pattern of phytoplankton growth. Mass-scale culture produce 1504 x 104 cells/ml for six days.
