Abstract

Bedog River is one of the rivers that passes through Bantul Regency and has biological resources, one of which is freshwater shrimp. The purpose of this study was to determine the types and potential of freshwater shrimp found in the Bedog River, Bantul Regency, and knowing whether the environmental parameters in the Bedog river are in accordance with the ideal conditions for the growth of freshwater shrimp. The research location was determined by purposive sampling method at three stations (ST), each station made three sampling points. In addition, environmental parameters were also measured including temperature, pH, salinity, river flow velocity, dissolved CO2, and DO. Data analysis was carried out descriptively by comparing the morphological characters of each type of freshwater shrimp. The data obtained are presented in tables and diagrams. The results of the study found four species of shrimp Macrobrachium sintangense, Macrobrachium equidens, Caridina sp. and Caridina elongapoda with a total of 116 individuals. The potential of each type of freshwater shrimp found in the Bedog River is for consumption and ornamental pets. Macrobrachium equidens, M. sintangense, and C. elongapoda have the potential to be consumed, while Caridina sp. potential as ornamental shrimp. Environmental parameters that are in accordance with ideal conditions for the growth of freshwater shrimp in the Bedog River are found at stations I and III, while at station II are less suitable for ideal conditions for shrimp growth because the river is polluted by industrial waste so that the water quality decreases.

Abstract

Abstract. Indonesia has a very high diversity of fish species. However, information on the richness of fish species in Indonesia is still limited. The Gajahwong River is one of the rivers with its upstream in Sleman Regency and the river flows through Yogyakarta Municipality and then through Bantul Regency and empties into the Opak River. The Gajahwong riverbank area is dominated by dense settlements and several factories so that household and factory waste dumped in the Gajahwong River has the potential to reduce its water quality. The purpose of this research was to determine the diversity of fish species found in the Gajahwong River, both native and introduced fish, and also to determine the abiotic environmental conditions. Sampling was done by means of purposive random sampling at three station points (I, II, and III) with each station divided into three sampling points. Measurement of the abiotic environmental parameters was carried out at each sampling point with three replications each. Fish samples were taken and identified. The results showed that there were 18 identified fish species, with details of which 13 were native to Indonesia and 5 (five) were introduced fish. The abiotic environmental parameters are in accordance with the water quality standards of class II-III, supporting the survival of fish in the Gajahwong river.
