Abstract

Navicula sp is a microalgae that is widely used for activities in the field of fisheries, particularly on Abalone hatchery which is now being developed. Stimulating Feed Water Usage (WSF) is expected to improve the quality and quantity of Navicula sp. The purpose of this study was to obtain information Navicula sp culture techniques with Water Stimulating Feed. This study used six treatments and three replications, namely: treatment A = Fertilizer standards, B = Fertilizer standard 80% and WSF 20%, C = Fertilizer standard 60% and WSF 40%, D = Fertilizer standard 40% and WSF 60%, E = Fertilizer standard 20% and WSF 80% and F = WSF 100%. The results showed that the optimum growth was greatest in treatment C = 99.33 x 104 cells/ml, followed by treatment D = 88 x 104 cells/ml, treatment E = 80.33 x 104 cells/ml, treatment F =78 x 104 cells/ml, treatment B = 59.33 x 104 cells/ml and treatment A =48.66 x 104 cells/ml. Thus the use of the WSF can affect the growth of Navicula sp. The observation of water quality on all treatments are in normal condition and temperature data obtained = 30-31 oC, salinity = 35 ppt, DO = 4.7 to 5 ppm, pH = 8.28 to 8.41 and NO2 = ,0.001 to 0.024 ppm

Abstract

The grouper fish hatchery has been growing rapidly include humpback grouper and tiger grouper. On the other hand there are many more types of grouper that has high economic potential, one of which is sand grouper (Epinephelus corallicola). E. corallicola including one type of grouper has a high economic value. Mechanical increased production of grouper culture is by the application of probiotics in aquaculture systems.This study aims to determine the role of probiotics in grouper aquaculture sand. D1-10 larval fish oil given 0.1 ml / m2, probiotic before use cultured using sterile fresh water for 8 hours and then filtered (bottom sediment can not participate), probiotics do when the larvae D1 - harvest with 0.25 -1 ppm and fish health in visual inspection is done every day. These results indicate an increase of the use of probiotics are able to improve the quality and quantity of production of larvae E.corallicola, results can be seen on Survival rate increased by 6.55%.

Abstract

Penelitian ini bertujuan untuk membandingkan pola pertumbuhan Spirulina sp. yang dikultur pada wadah yang berbeda. Tahapan dalam penelitian ini yaitu persiapan dan sterilisasi wadah dan media, pembuatan media kultur Spirulina sp. dan vitamin, pemilihan inokulan Spirulina sp., dan kultur Spirulina sp. Hasil penelitian menunjukkan bahwa fase eksponensial pada wadah kaca terjadi pada hari ke-9 dengan total biomass sebesar 53,375 x 105 sel/ml, berbeda dengan wadah plastik yang terjadi pada hari ke-8 dengan total biomass sebesar 16,993 x 105 sel/ml.
