Abstract

Freshwater crab is widely distributed in river, lake, swamp, canal, and pond. Riau Province has many freshwater crabs, however biological information of these organisms are poorly known. This study aimed to understand the freshwater crab types from the Kampar Utara District, Riau Province. Samples from 14 sampling sites, in the Sawah, Sendayan and Sungai Jalau village had been collected from March to April 2013 using bamboo traps and scoop net. There were 178 crabs captured and all of them belonged to a single genus, Parathelpusa. Numbers of crab were obtained from the shallow riverines with numerous aquatic vegetation and no crab caught in the rivers. Based on the results, it can be concluded that the habitat of Parathelpusa in Riau is shallow riverine with dense aquatic vegetation.

Abstract

Rama-rama is one of typical macrofauna from the mangrove ecosystem. The existence of this organism can be seen easily from the appearance of mud mounds in the ground surface as a result of bioturbation activity. The purposes of this research were to understand rama-rama species in the coastal area of Bukit Batu and the characteristic of bioturbation conducted by this organism and also to obtain the valuation of important impact of this activity to its environment. This research had been conducted from September to November 2013 in Bukit Batu and Tanjung Leban villages. Observation was conducted in four line transects, 1100 m length, from the edge of the water during the lowest tide. There were 10 transects (10 m x 10 m) placed along the line (100 m interval). The diameter and height of mud mounds, diameter of the hole, soil bulk density and the ability of rama-rama in carrying the soil / day were observed. Information on impact of the presence of the rama-rama on the social condition of people was obtained by interviewing people living around the coast. The results show that there were 2 species of Thalassina, namely T. anomala and T. spinosa. Rama-rama bioturbation activities were influenced by its body size and soil bulk density. The average of soil carrying capacity of each rama-rama was 740 cm3/mound/day. Therefore, with the average density of mound was 3,9 mound/m2, the soil carried was around 2900 cm3 /m2/ day or 11.000 m3/ha. It can be concluded that the soil carrying capacity of the rama-rama is potential to affect the coastal area environment.

Abstract

Mud lobsters (Thalassina) are one of the most common macrofauna in mangrove ecosystems, especially in the Indo-Pacific region. The presence of this fauna is typically marked by mud mounds that are hardly overseen in its habitats, as a result of its bioturbation activities. This study, which focused on Bukit Batu coastal area in Riau Province, aimed to identify the occurring species in the area, describe the distribution and abundance patterns along the sea-inland gradient, and identify critical factors affecting the patterns. Observations were carried out in the focal area from September to November 2013 along four 1100 m-long transects, on each of which 10 quadratic plots of 10 m x 10 m were established in 100-m interval. The observed parameters were the characteristics of vegetation cover, soil BD, groundwater level, groundwater salinity and pH, beside number of “active” mounds. At least two species of mud lobsters were countered, T. anomala and T. spinosa. Mud lobster mounds were totally absent at a distance of 0 and 100 m from lowest-tide line, while most abundant at a distance of 200 m, with 9.4 mounds/m2. The abundance decreased sharply following the increasing distance toward inland, which was down to 0.09 mounds/m2 at 1100 m. Mounds were more evenly distributed toward the sea, while increasingly random as their density decreased. Groundwater salinity was the most critical affecting mound distribution and abundance.

Abstract

Monopterus albus, Zuiew 1793 (Synbranchidae) or swamp eel is rich in proteinand commonly used in Riau’s culinary. It is easily found in muddy areas, ricepaddy fields and in the organic material polluted area where this fish is able totolerate to the polluted environment. Fish living in the organic polluted area mayface the risk of parasite infection, including the zoonotic parasite that may infecthuman being. To understand the parasite present in swamp eel, a study had beenconducted. The study area of this research was a domestic polluted swamp area inthe Sawah Village (Kampar Regency Riau). Thirty eels from this area were usedfor parasite identification study. Results showed that among the samples, 14 fisheswere infected by nematode parasite Gnathostoma spp. This parasites were presentin the gonad, liver, body wall and peritoneum. The parasites were found in 5developmental stages namely egg, 1 st , 2 nd , 3 rd and 4 th larvae.

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

Abstract

Pangasius polyuranodon is one of freshwater fishes that inhabit the Siak and Kampar Rivers in Riau. Water qualities in those areas are different. Availabillity of food and the success of reproduction are important factors for the fish existence. To understand the stomach content and reproductive biology of this fish, a study has been conducted from October – December 2016.The fish was sampled in the Siak and Kampar Rivers. Fifty fishes were taken from the Siak River and fifty three fishes were collected from the Kampar River. Stomach content of the fish was analyzed as a basis to calculate the Preponderance Index (PI). Fecundity was analyzed using a gravimetric method. Results shown the feed of P. polyuranodonconsist of bivalve, gastropods, insects, crustacean, fish, palm fruit (Elaeis guineensis), fruits, leaves and seeds. The main food of P. polyuranodon in Kampar River was bivalve (74%) and that of the Siak River were insects (55%). All of fishes captured shown trace of developing gonads. During the 4th maturity stage, the main food of P. polyuranodon from the Kampar River was bivalves and that of the Siak River were insects. Based on data obtained, it can be concluded that this fish can be categorized as omnivore, and they tend to choose high content protein and fat feed during gonad development. The ability of fish in consuming fruits indicates that P. polyuranodonisafrugivory fish. Keywords: Pangasius polyuranodon, Feeding Habit, Omnivorous,Frugivory Fish
