Abstract

AbstractTeluk Petai Lake is one of the oxbow lakes in the Buluh Nipis Village. This lake is inhibited by various types of aquatic plants and they almost cover the surface of the lake. A study aims to understand the types and density of the aquatic plants was conducted from October to November 2020. A survey method was applied.   Aquatic plant samplings were conducted 4 times, within a month period. The plants collected were then identified based on Van Steenis (1981). Results shown that there were 7 species of aquatic plants present and they are belonged to 5 classes and 7 families. They are Eichhornia crassipes, Ipomoea aquatica, Salvinia natans, Myriophyllum spicatum, Polygonum sp., Paspalum commersonii and Heminthus micranthemoides. The most common plant is Eichhornia crassipes (23-31 organisms/m2) with relative density ranged from 27.87 to 42.04 %. While the rarest was Paspalum commersonii (17.2 organisms/m2) with relative density 21.00 % and biomass (12,6-25,4 g). In general, the relative density of the aquatic plants in Teluk Petai Lake can be categorized as rare to moderate.Keyword: Oxbow Lake, Riparian Plant, Eichhornia crassipes

Abstract

AbstractBarau fish (Hampala macrolepidota) is a carnivorous fish found in Tanjung Kudu Lake and Teluk Petai Lake. The quality of the waters in the two lakes is different, it is thought that it has an influence on the availability of food in the waters, and will make a difference to the stomach contents of the barau fish. To find out the stomach contents of barau fish, a study was carried out in October-December 2020. From the data analysis using the Index of Preponderance (IP), 55 fish samples from Lake Teluk Petai and 30 from Tanjung Kudu Lake, the results obtained shows that the main food of Barau fish is fish, with an IP value of 68.60% from the Teluk Petai Lake and 54.59% from the Tanjung Kudu Lake. Other types of food found in the stomach of barau fish are insects, plants and crustaceans. Of the two lakes, only insects, there were significant differences after statistical tests were carried out. The results above show that the water quality influences the availability of food for barau fish. Keywords: Petai Bay Lake, Tanjung Kudu Lake, Gastric Fill, Barau Fish

Abstract

AbstractThe Teluk Petai Lake is an oxbow lake that received water from the Kampar River. The lake, however, received domestic pollutant that negatively affects the water and thus affect the life of fishes, including Hampala macrolepidota living in that lake. To understand the growth ring pattern in the otolith of that   fish, a study was conducted on November to December 2020. The fish was sampled using nets with 3/4 and 2,3 inch mesh size, 4 times, once/ week. The fish captured was then measured, weighed and the otolith (sagita) was removed. The otolith was then sticked in slide glasses using Crystalbond Amber 509 and then shaved manually using whetstone to reveal the growth ring patterns. The dark ring was identified using a binocular microscope. Results shown that  among 50 fishes captured (200 – 350 mm TL,  90 – 320 gr BW), 48 fishes have dark growth rings, 1 – 3 rings/ fish. The distance between the otolith’s nucleus and the 1st  growth ring was various, ranged from 0.1 – 0.75 mm, indicating that the formation the growth ring is individual and it is not resulted from mass evidence. Based on data obtained, it can be concluded that  mostH. macrolepidota in the Teluk  Petai Lake faced problems that hampered their growth as indicated by the formation of dark rings in the otolith.Keywords: Oxbow lake, Growth pattern, Sagita, Hampala barb

Abstract

Mimi merupakan organisme yang mendiami daerah Muara Sungai Paluh Sebilang. Namun informasi tentang mimi di daerah tersebut belum ada. Untuk memahami/mengetahui jenis mimi yang ada di muara sungai Paluh Sembilang,  penelitian ini telah dilaksanakan pada bulan April 2019. Daerah pengambilan sampel berada di sekitar pantai dan muara sungai Paluh Sembilang. Pengambilan sampel mimi dilakukan setiap hari selama dua minggu. Mimi ditangkap menggunakan mini trawl dengan mesh size 50 mm atau 2 inch dan mimi yang berada di pantai dapat di pungut langsung menggunakan tangan. Karakteristik morfometrik dan meristik mimi dianalisis secara deskriptif. Sampel mimi kemudian diidentifikasi. Terdapat 138 ekor  mimi (67 jantan dan 71 betina). Spesies mimi yang ditemukan terdiri dari dua spesies, yaitu Tachypleus tridentatus (61 Jantan dan 67 betina) dan Carcinoscorpius rotundicauda (6 Jantan dan 5 betina). Masing-masing dari setiap spesies memiliki karakter morfologi yang berbeda. T. tridentatus memiliki ukuran tubuh besar (33,08-34,89 cm) dengan warna abu-abu kehijauan. Sedangkan C. rotundicauda memiliki ukuran tubuh kecil (27,38-25,8 cm) dengan warna hijau tua hingga coklat kehijauan. Pola pertumbuhan relatif menunjukkan bahwa pertumbuhan jantan lebih cepat daripada betina.

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
