Over exploitation of consumed fishes causes declining of targeted fish populations that will lead to a cascade effect to the guild compositions. The change of carnivorous, omnivorous and herbivorous fish populations drives to the food chain destructions and unstable ecosystems. The objective of this study was to build fish community modelling based on guild compositions. This study was conducted on fish communities in the Banjaran River. The data collected were species richness, the abundance of fish and the guild composition among carnivore, herbivore, and omnivore. Survey and purposive random sampling technique were applied and Banjaran River was divided into five sites based on the physical characteristics of the environment and fishing activities. Species richness data were analyzed by ANOVA, the composition of the carnivorous, omnivorous and herbivorous fish was analyzed descriptively based on the guild pyramides. About 115 individuals consist of 17 species belong to 5 families were found. The species richness in the five sites in was relatively similar (P > 0.05 (P = 0.269)). The fish community in site 3 had the balanced composition which was composed by 3% carnivores, 21.2% omnivores and 75.8% of herbivores. This fish community modelling could be an an alternative way to manage fish community. By controlling the carnivorous fish population, the natural resource especially fish as food resource will sustain and the species loss will be prevent.

Rasbora is a genus of freshwater fish of the family Cyprinidae. Three species belonging to this genus were found in Java Island; R. aprotaenia, R. lateristriata, and R. argyrotaenia. Rasbora inhabits clear running water with sandy and gravel bottom. This study aimed to determine the longitudinal distribution of Rasbora spp. based on their species richness and abundance at Banjaran River; to determine the population structure of Rasbora spp based on their body weight, standard and total length; and to identify interactions between physical-chemical factors with species richness and abundance of Rasbora spp. This research was a survey, with purposive random sampling technique applied to collect samples. The research divided the study sites into five stations based on their altitude and topography. The Cluster Analysis was calculated based on species richness and relative abundance of Rasbora spp., while the longitudinal distribution and the population structure were presented descriptively. The interaction between the physical-chemical factors and the species richness and abundance of Rasbora were analyzed using Principal Component Analysis (PCA). Thi study found two species of Rasbora, namely Rasbora argyrotaenia and Rasbora lateristriata with 80 and 2 individuals respectively. R. argyrotaenia was distributed longitudinally along Banjaran River. Meanwhile, R. latestriata was only found at the upstream. Based on the body weight, the population of R. argyrotaenia at the station three were found highest by the average body weight of 1–6 gr of a total 31 individuals. The maximum measurements of the standard length were observed at the station 3 with a range of diameter 4.0–5.9 cm of 30 individuals. The total length were also found at the station 3 with a range of measuremtnt 5.0–7.9 cm of 33 individuals. R. latestriata was found only two individual with body weights measured were 9 gr and 10 gr, the standard lengths were 7.6 and 8.5 cm, and the total lengths were 9.5 and 10.5 cm. The distribution of R. argyrotaenia was influenced mostly by pH, the speed of the water, and DO. The presence of R. lateristriata was influenced primarily by BOD and depth.

Oxyeleotris marmorata Bleeker or marble goby originally from China and is introduced to Indonesia in 1927. This predator fish could be a threat to freshwater fish diversity, thus its population should be controlled. In order to support their control efforts, this research attempted to evaluate the population size and exploitation rate of O.marmorata in Sempor Reservoir, Kebumen. Survey with purposive random sampling were applied by dividing the Sempor Reservoir into three parts (inlet, middle and outlet) and each part was represented by two sites. The population sizes of fish were analyzed using F-test and the exploitation rates of O.marmorata were analyzed using FiSAT II. The result shown that the population sizes of O.marmorata in inlet, middle and outlet were is different. (Fcal= 7.544 with P= 0.03). The fish population in middle possessed L∞ = 39.06, K = 2.0 and t0 = -0.44, and fish population in outlet with properties L∞ = 37.59, K = 2.1, and t0 = -0.42. The growth patterns of O.marmorata in both parts were relatively similar. The mortality of O.marmorata in the middle part was more caused by fishing activities, meanwhile in the outlet, the mortality occurred naturally. The exploitation rate in middle (E= 0.55) and in outlet parts (E=0.10). It seems that the middle part of Sempor Reservoir was 5 times more exploited than in the outlet part. Population control could be conducted by fishing O marmorata with 13.38-17.30 cm in length in outlet part and fishing (E) should not more than 0.5.

Alien fish are introduced to diversify farmed fish, ornamental fish, or disease vector controllers. Alien fish in aquatic generally becomes a threat for indegenous fish as competitors for food, space and as predators. This will affect fish structure populations and results in niche segregation (space utilization) to avoid competition. Niche segregation encourages certain fish to occupy niches spatial and temporal diferently. Niche segregation may also occur between O. mossambicus and O. niloticus in the Banjaran River. This research was done by using a survey method with the Purposive Random Sampling technique. Sampling was conducted at five selected stations along Banjaran River every two weeks from July until September 2018. Research variables were O. mossambicus and O. niloticus populations with parameters abundance, length and weight of fish The supporting variable was water quality with the physical parameters were temperature, brightness, and current and the chemical parameter were dissolved oxygen (DO) content, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and also potential hydrogen (pH). Data on fish population structure and niche segregation were analyzed descriptively. Correlation between physical-chemical aquatic factors and fish abundances were analyzed using PCA (Principal Component Analysis). The result showed that the O. mossambicus population was more than O. niloticus. The abundance of O. mossambicus in the five stations were different (p: 0.005), while the abundance of O. niloticus were relatively the similar (p: 0.184). There were differences in length distribution of O. mossambicus (p: 6.934E-09) and O. niloticus (6.174E-05) at five stations. The weight distribution of O. mossambicus at five stations was significantly different (p: 3.609E-09), and the weight distribution of O. niloticus (p: 6.631E-05) was also different. The temporal niche segregation between O. mossambicus and O. niloticus was recorded in stasiun 5. The abundances of O. mossambicus and O. niloticus were negatively correlated to the physical and chemical factors of the water quality of Banjaran River
