Abstract

ABSTRACT            Fungal are a group of microbes that often cause disease in comet fish. Diseases caused by fungi are secondary infections, and can cause more than 50% death. The objective of the study was to find out the species of pathogenic fungi in comet fish and what is the prevalence of fungi that infect comet fish. The method used was survey at the location of the Ornamental Fish Shelter, Jalan Bukit Barisan, Tangkerang Timur Village, Tenayan Raya District, Pekanbaru City. The fish used were 6 - 8 cm as many as 15 tails . Conventional identification includes macroscopic inspect of fungi colonies and microscopic of fungi hyphae. Molecular identification was carried out by PCR (Polymerase Chain Reaction) technique and analyzed with Bioedit, BLASTn and MEGA applications to find out the phylogenetic tree. Research parameters include hyphae size and fungi prevalence. The results of conventional identification techniques found the 4 species of fungi, includes Aspergillus niger, Penicillium sp., Curvularia sp., Fusarium sp.. The result of molecular identification techniques found the species of fungi, includes Curvularia pseudorobusta with homolog value 93%, Trametes corrugate with homolog value 99%.,The conclusion from the identification results found two types of fungi that are pathogenic in comet fish, includes Fusarium sp. and Curvularia sp.. Fungal prevalence from 15 samples was 73,3%. Wide hyphae of fusarium sp. is 1,09 µm, and Curvularia sp. is 1,52 µm. Keywords: Fusarium sp., Curvularia sp., Carassius auratus.

Abstract

Mystacoleucus padangensis is relatively small Cyprinids that commonly inhabit theToba Lake and surrounding waters. A study aims to understand the stomach contentand its relation with size, sex and level of maturity of gonads has been done onJanuary to April 2014. There were three stations, namely the Naborsahan River(Station I), river mouth of the Naborsahan River (Station II), and the Toba Lake(Stasiun III). There were 515 fishes captured, however only 52 fishes were used forstomach content analysis study as the other having almost empty stomach (stomachfullness index less than 50%. Parameters measured were Index of Preponderance(IP), type of food based on Total Length, sex, and maturity level. Results shown thatthe main food of this fish is Rotifera (IP 41.78%). Small fishes (less than 81 mm TL)tend consume Bacilliariophyceae (76.17%), medium sized (80 – 93 mm TL) fish tendto consume Cyanophyceae (39.87%), while the big fish (more than 139 mm TL)prefer to consume Rotifera 38.27-58.38%) and Xanthophyceae (52.51%). Based onsex, the male eat more Cyanophyceae (35.60%), while that of the female Rotifera(39.86%). Fish with relatively low maturity level (2nd and 3rd maturity levels) tend toeat Cyanophyceae (82.56%) and Bacilliariophyceae (76.29%) respectively, whilemature fish prefer Rotifers (81.58%). Based on data obtained, it can be concluded thatthe diet of M. padangensis was various, and it is related to body size, sex and gonadmaturity level.Keywords : Mystacoleucus padangensis, Stomach Content Analysis, PreponderanceIndex, Sumatera Utara

Penelitian ini dilaksanakan pada bulan Mei 2014. Eksploitasi kerang lokan (P.expansa) yang dilakukan nelayan selama ini tanpa memperhatikan ukuran yangditangkap mulai dari yang besar sampai yang relatif kecil. Tujuannya untukmengetahui distribusi dan nisbah kelamin kerang lokan. Metode survey digunakanpada 3 zona intertidal, selanjutnya dilakukan analisis sampel dilaboratorium.Kelimpahan kerang lokan tertinggi ditemukan pada zona upper sedangkankelimpahan yang terendah ditemukan pada zona lower. Nisbah kelamin pada zonalower seimbang, sementara zona middle dan upper sebaliknya, namun rata-ratanyaseimbang. Pola distribusi mengelompok pada zona upper dan merata pada zona lowerdan middle (Indeks morisita 1,052 dan 0,643) Analisis Chi – square memperlihatkansebaran yang tidak acak (χ2 hitung ˂ χ2 tabel).Kata kunci: Kerang Lokan (P. expansa), Distribusi, Nisbah Kelamin

Abstract

This study was conducted on 28 June to 5 July 2013 in the village of Bay Pambang Bengkalis Riau Province. The purpose of this study was to determine the effect of hook type (Type J, Kirby and Crycle) on long line catches (mini long line). The method used in this study is the experimental method. The results are presented in tables and histograms were analyzed using one way ANOVA formula. Based on the research it can be concluded that the type of hook J, Kirby and Cyrcel get the value of the average value of 2.77; 4.57 and 3.75. Where hook Cyrcel Kirby and more effective than the hook type A (Standard), from One Way Anova test hypotheses (Analisysisi of Variance) is 0089 less than the value of α = 0.05 level (p-value <α) gives the rate of fishing is not significantly different.Keywords : Long Line, Hook, Catch

Abstract

This research has been done in the Pinang Dalam Lake Buluh Cina Village SiakHulu Subdistrict Kampar District Riau Province. This research aims to understand thevertical profile of chlorophyll-a in this lake. The research used survey method. Thechlorophyll-a samples were collected from three station namely station I at inlet of lake ,station II in the midle of lake and station III the end of lake. There were three samplingsites in each station were in the surface, 1.5 Secchi depth and 2.5 Secchi depth. Samplingwas done three times, once a week. The result shown chlorophyll-a concentration insurface :17.26 μg/L -21.44 μg/L, 1.5 secchi depth 11.60 μg/L-14.43 μg/L and in 2.5 secchidepth 9.98 μg/L - 12.41 μg/L. A chlorophyll-a concentration in surface higher than in the1.5 secchi depth and 2.5 secchi depth. The chlorophyll-a concentration decrease with thedepth. Water quality result shown pH:5; DO: 2.60-5.88 mg/L; CO2: 6.79-13.31 mg/L;nitrate: 0.0134-0,093 mg/L; phosphate: 0.03-0.15 mg/L; phytoplankton abundance:3,420,423-4,293,075 cell/L; depth: 180.67-429 cm; transparency: 52.5-54.5 cm;temperature: 28oC-28.34oC. Based on data obtained, it can be concluded the consentrationof chlorophyll-a in Pinang Dalam Lake showed the trophic status was mesotrophic and allwater quality still support the life of aquatic organisms.Keywords : Chlorophyll-a, the vertical profile, Pinang Dalam Lake
