Abstract

Inventory study on aquatic plants was conducted in Rawa Taliwang lake, located at West Nusa Tenggara. The area of this water body total ranges from 584 to 913 ha and most of the water surface area is convered with aquatic macrophytes. In 1990 the fish yield was 241 ton and than declined to 36,9 ton in 1994. The objective of this study was to evaluate the species distribution and abundance of the aquatic plants in the lake. Field investigations for ecological study of aquatic plants were conducted in June and in October 1999, representing dry and rainy seasons, repectively. Result of this study showed that the importance values of the aquatic plant during the wet seasons (6,70-71,06%) were not significant different compared than that in dry seasons (6,59-70,13%). The aquatic plants found in Rawa Taliwang were consisted of 16 species and they covered 70-80% of the water surface area. The important floating aquatic plants were Salvinia molesta, Nelumbo lutea, Nymphaea pubescens, Pistia stratiotes and Monochoria vaginalis, whereas the submerged aquatic plants were dominated by Hydrilla verticillata, Ceratophyllum demersum, and Najas indica.Keywords : aquatic plants, density, dominancy, frequency, importance value

Abstract

Seputih river basin located at Center of Lampung is not only utilized by fisheries sector, but also by other sectors such as industry and water irrigation, Industrial pollution has significantly affected on the degradation of the fisheries resources and a mass mortality of cultured fish in floating cages. To cope the ecological damage caused by the pollution need am in integrated management of the river basin. Causes and effects of the pollution on the fisheries resources and their ecologies, and the importance of an integrated management of the river basin based on the community management were discussed.Keywords: river basin, pollution, fisheries, cage culture, integrated management

Abstract

This study in aiming to evaluate response of knife fish to various life fish species as a diet sources in controllable tank. After adapting to experimental condition, 36 tested fish collected from nature of 326.6 ± 184.1 g in individual weight were randomly stocked in 7 fiber tanks at a rate of 4-5 fish per tank and fed on life fishes in fingerling size at different combinations (common carp, tilapia, shrimp, carp+tilipia, tilapia+shrimp, carp+tilapia+shrimp) every 6 hours for 5 days of culture period. The result showed than knife fish prefer combination life food of common carp and tilapia, and then followed by common carp, tilapia and shrimp. Night was feeding time for knife fish.
