Abstract

Catfish (Clarias gariepinus) was cultured with an aquatic plant, water hyacinth/eceng gondok  (Eichornia crassipes), kangkung air (Ipomea aquatica) or kapu-kapu (Pistia stratiotes) in concrete ponds, for 3 months. Catfish cultured without aquatic plant was used as a control. The experiment was carried out to evaluate the survival rate as well as the growth of fish and aquatic plants.The survival rates of catfish cultured with I. aquatica, E. crassipes, and P. stratiotes were 76, 87, and 98%, respectively. In addition the survival rate of catfish cultured without any aquatic plant was 93%. The weight gain of catfish was 14,1-16,2 kg per pond. Whereas, the total weight gains of aquatic plant were 37,0,  27,7 and 7,7 kg per pond for E. crassipes, P. stratiotes, and I. aquatica,. Respectively. Dissolved oxygen, and the concentrations of NH3, NH4+ and PO43- in water with aquatic plants were higher than that of in water without aquatic plant. However, the concentration of CO2 was higher in water with aquatic plant.

Abstract

Sea horse (Hippocampus kuda) is one of the ornamental marine organisms and raw material of traditional medicine. Since 1993, Seafarming Development Centre, Lampung has pioneered a research and  culture  of sea horse in Indonesia. The serious problem in the culture of sea horse is pathogenic bacteria caused death of juveniles and broodstocks. The objective of this study was to identify pathogenic bacteria isolated from  sea horse in Seafarming Development Centre. Koch Postulate test was carried out, and then the pathogenic bacteria were identifed by morphological and biochemical tests. Results showed that from a total of 6 bacterial strains isolated from diseased sea horse, 3 strains were pathogenic bacteria to sea horse. These 3 pathogenic bacteria caused identical disease signs with the initial disease signs when the bacteria were isolated.  Morphological and biochemical tests suggested that  the pathogenic bacteria could be identified to be Vibrio fluvialis, V. alginolyticus and V. hollisae.
