Abstract

The objective of this study was to determine sedimentation rate and dispersion of organic waste from lobster culture on cage in Ekas Bay, West Nusa Tenggara Province. Measurement of sedimentation rate was conducted every month during the process of cultivation lobster. This measurement was done by setting up a sediment trap under and around the cage. The result of this study showed that sedimentation rate under the lobster cage within 270 days ranged from 14.92 to 27.33 (20.66±4.60) g/m2/day. The organic waste did not disperse far away from the cage because of the small current rate around the cage location of 0.068 to 0.2 m/s. Feces and residual feed settling velocities followed the current direction within the range of 0.0373 to 0.072 m/s with 8.50 m of water depth. According to this result, dispersion of feces particle and residual food was between 8.24 and 45.58 m from the cage. In order to prevent an accumulation of waste particle on the water bottom, the distance between cages needs to be set to at least twice of the farthest distance of particle dispersion which is 2 x 45.58 = 91.16 m or about 100 m. Keywords: sedimentation rate, waste dispersion, lobster culture, Ekas Bay

Abstract

Constraints, that are often faced by farmers, are pests and diseases that can reduce shrimp quality and production failure. Diseases that often attack shrimp are bacterial diseases such as vibriosis. The bacterial disease is usually treated using antibiotics. In this study, the antibiotic used was derived from Rhizophora apiculata mangrove leaf extract which contained active compounds as antibacterial. The use of R. apiculata mangrove leaf extract is expected to be able to improve the growth performance of white shrimp through enhancing the immune system. This study aims to determine the effect of R. apiculata mangrove leaf extracts on the growth performance of white shrimp (Litopenaeus vannamei). This research was conducted for 40 days. The treatment given was the addition of R. apiculata mangrove leaf extract into shrimp feed namely P1 control without the addition of extract, P2 was given 0.5% mangrove extract, P3 was given 1% mangrove extract and P4 was given 2% mangrove extract. The results obtained for the growth performance of the best treatment white shrimp on P4 (feed + mangrove extract 2%) with the results of absolute weight growth of 17.41 g, specific growth of 21.37%, survival of 93% and feed conversion of 1, 1 R. apiculata mangrove leaves can improve the growth performance of white shrimp through absolute weight growth, specific growth rate, survival and feed conversion ratio values, the best value is obtained at 2% extract dose with each value of 17.31 g, 21.37%, 93%, and 1.1%.

Abstract

Mud substrate so far is commonly used for eel cultivation. However, this method has some weaknesses as to the long time preparation and the difficulty in monitoring. One of the solutions is the use of clear water as a medium of maintenance. This research is aimed at finding the effect of water level on the growth and the life sustainability of rice eel without substrate. The eel used in this study has an average weight of 19.38+ 1.30 gram and an average length of 6.78 + 1.01 cm which is kept for the period of 70 days in two different water levels; that is, (A) 3 cm and (B) 5 cm. Result of the free t test shows that treatment B gives higher absolute length growth with a value of 2.24 cm and the life sustainability around 80%. However, there is no real difference (P?0.05) in the absolute weight growth (2.47-2.83) and growth rate of specific weight (0.45-050%). Keywords: eels, water level, survival rate, growth
