Abstract

Dam and streams around the University of Riau is inhabited by many types of aquatic organism, including prawns. Scientific information of those organisms, however, is almost none. To understand the types of freshwater prawns present in that area. A research has been conducted from February to April 2017. Sampling areas were in the dam, pond and streams around the University of Riau. Freshwater prawns sampling were conducted once/week for a month period. Prawns were caught using a scoop net (mesh sixe 0,5 cm). Morphometrical and meristical characteristics of the prawns were then analyzed descriptively. The prawns sampled were identified. There were 106 prawns. The freshwater prawns species present were consisted of a single species only, namely Macrobrachium tolmerum, Riek, 1951 (Palaemonidae). This species characterized by schapocherite length that is shorter than rostrum length, rostral teeth sub-equally spaced, 8-10 teeth in the dorsal and 4 teeth in the ventral of rostrum. In male, the rostrum, propodus, carpus and merus are longer than those of the female.

Abstract

Heterotrophic bacteria in marine ecosystems have important as decomposer of organic material into the elements essential. This group of bacteria can be found in a variety of habitats including marine sediment. This research aims to isolate the heterotrophic bacteria and the activity against pathogenic (Vibrio alginolyticus, Aeromonas hydrophila and Pseudomonas sp). The research was conducted from November until December 2016. Samples were obtained from the waters of Tanjung Medang, District of North Rupat, Riau Province. Isolation and antagonistic test were conducted at the Laboratory of Marine Microbiology and Biotechnology Department of Marine Sciences Faculty of Fisheries and Marine. In this research was a survey method where heterotrophic bacteria from the sediment were isolated on marine agar medium by pour plate and streak quadran techniques. Activity of the heterotrophic isolate against bacterial pathogens was conducted using diffusion agar on Mueller Hinton Agar (MHA). The number of heterotrophic bacteria ranged from 4,4 × 106 up to 13,5 × 106 CFU/g.Twelve isolates of the sediment bacteria were selected for the antagonism test. However, only nine isolates (Isolate A, C, E, F, O, S, V, W, Z) were able to inhibit the growth of pathogenic bacteria. One isolate (E) performed the highest ability to inhibit the growth of patogens (V. alginolyticus, A . hydrophila and Pseudomonas sp).Keywords: Isolation, Heterotrophic, Sediment, Antagonism, Pathogenic Bacteria.

Abstract

Parathelphusa pardus is a new freshwater crab species found in the swamp area in the Sawah Village. A study purpose to understand the type of food consumed by the crabs has been conducted in October-November 2016. Crab stomach was removed and its content was analyzed by using a microscope. Type of food present was identified and noted and the Index of Preponderance was calculated. The crabs were captured using a traditional fishing line and traps. Results shown that the stomach of P. pardus contains detritus (64,87%), phytoplankton (28,60%), crustacean remains (5,88%), and algae (0,49%). In each molting status, as well as in male and female crab, the food composition of P. pardus is not different. These crabs may accelerates the degradation of litter particles in the swamp, provide feces as natural food for other small organisms and improve the soil oxygenation through their burrows.Keywords : Parathelphusa pardus, stomach content analyis, Index of Preponderance
