Abstract

The aim of this research was to identify the species of migratory birds in the ecosystem of salt water lake of Gili Meno and their specific characteristics of habitat. Data collection for birds, mangrove and fish species has been carried out in September and October 2013.  In this study, a Shannon-Wiener Diversity Index and Importance Value Index (IVI) of mangrove vegetation were calculated to identify carrying capacity of mangrove population in the form of specific habitat in salt water lake of Gili Meno. This research has identified 17 species of birds which are divided into 5 families: Scolopacidae, Charadriidae, Ardeidae, Meropidae and Alcedinidae. Moreover, 3 species of mangrove were discovered that are A. marina, A. lanata and E. Agallocha, as well as one species of fish (Mujair fish/O. mossambicus). N. Nycticorax and B. Striatus were well-known to have higher population than other bird species.  The Diversity Index showed that mangrove vegetation in the ecosystem of salt water lake of Gili Meno has a low species diversity (0.565). This is due to higher dominance of one species than the others.  What is more, the IVI of A. marina demonstrated a fairly significant value compared to that of other species (189,01).  Mangrove vegetation which surrounds the ecosystem of salt water lake of Gili Meno has formed a unique habitat and and an ideal stopover site for migratory birds. The ecosystem not only provides shelters from predators but also supplies for various abundant feeding sources.  The lake it self is rather shallow and muddy around the shore which gives advantages for the migratory birds to obtain plenty small fish from the lake.

Abstract

The application of intensive keramba in rivers could affect the presence of parasite organisms throughout  the river downstream. The aims of this research are to find out the diversity of parasite species and the effect of intensive aquaculture method developed by the community on the presence of various parasitic organisms, particularly in the downstream area. A total of 65 Tilapia fish samples (O. niloticus) that was collected from 3 areas ( 15 samples from upstream, 25 samples in keramba and 25 samples from downstream areas) have been examined  in the laboratory of Faculty of Mathematic and Natural Science, University of Mataram. Methods employed  to identify parasites that  infected fish samples are native method and flotation method. This research has identified 7 species of parasites which were divided into 2 groups: ectoparasites (Trichodina sp., Amylodinium sp., Oogonium sp., Dactylogirus sp., Trematode) and endoparasites (Entamoeba sp. dan Camallanus sp.). Diversity index calculation  indicated that parasite organisms in upstream area were lower in number than that in the downstream and intensive karamba area (H’= (0,825; 1,596 dan 1.324 respectively).  These data has showed there was a difference in species diversity and evenness index of parasite organisms in the upstream, downstream and intensive keramba area. In conclusion, there was significant influence of the application of intensive keramba on the appearance of various parasite organisms that could affect the sustainability of  fish aquaculture.
