Abstract

Pepudah fish (Rasbora lateristriata) is one type of fish species found on the penyonggak river that flows from the spring located in Tete Batu. Cultivation alternative inexpensive is needed to improve the economy society. However, to conduct the cultivation business required basic data on the characteristics of morphology, ecology and reproduction. This research aims to explain and consider the characteristics of morphology, ecology and reproduction of pepudah fish that live in penyonggak river. Sampling was conducted at 3 stations which are upstream, middle and downstream of penyonggak river. Sampling was done three times of different time span. Research was conducted in May - June 2017. Measurement of morphometric pepudah fish as many 29 characters. Results were tested by statistic method, that is regression analysis method using Microsoft Excel software. Research result shows of Total Length (TL) range between 45-90 mm and weight between 0,96-7,51 g. The largest ratio of standard length to total length of pepudah fish is found at downstream station with 81,44%. Value of correlation and determination of each character to TL mostly show the value >80% which means have very close relationship and very strong effect. Growth pattern of long with the weight of the nearly balanced is in the middle station with the value b=2,98. Analysis of the overall condition factor shows range of 0,80 to 1,37 and average of gonad maturity stage is at GMS III. Population habitat of penyonggak river in the coastal area provides maximum growth for the pepudah fish.
