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

AbstractThe aim of this research was to determine the effect of stocking density and feeding frequency on growth and survival rate of hard-lipped barb larvae. This research was conducted from July-August 2018 at Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty Riau University. The Method used is a Factorial Completely RandomizedDesign with two factors, the first factor is stocking density with three levels namely 3 larvae/L (T3), 5 larvae/L (T5) and 7 larvae/L (T7). While the second factor is feeding frequency 2 times/day (F2) and 4 times/day (F4).To minimize errors, each level of treatment was repeated 3 times. The result showed that stocking density and feeding frequency were significant on absolute weight, absolute length, average growth rate, survival rate and feed efficiency. The treatment T3F4 (3 larvae/L and feeding frequency 4 times/day) was resulted the highest value with an absolute weight of 1,58 gr, absolute length 3.72 cm, average growth rate of 14.09 %/day, feed eficiency 19 % and survival rate 91,11 %. The water quality parameters during research was in optimal range temperature 25,3-27,8°C, pH 5,1-6,5 and dissolved oxygen 4,1-5,2 mg/l. Keywords : Stocking denstity, Feeding frequency, Growth, and Survival rate

Abstract

ABSTRACT Purse seine is considered to be the most productive fishing gear to catch pelagic fish, so that in 2014-2017 there were 50 units of ships carrying out loading at the Samudera Bungus Oceanic Fishing Port operate in the Fisheries Management Area  of the Republic of Indonesia (WPP 572) with the largest production of catches 887.124 Kg, but in conducting an arrest operation have you got the optimal catch. Because during this time the operation of the arrest was only determined based on experience. This study aims to determine the composition of the catch purse seine based on the main and side catches and to know the pattern of the catching season. The method used is a direct survey method which includes primary and secondary data containing the last 4 years (2014-2017) obtained from the Bungus Ocean Fishing Port. The catches during the study were 10 types of fish: fish cakalang (Katsuwonus pelamis), tongkol krei (Auxisthazard),madidihang (Thunnus albacares), mata besar (Thunnus obesus), lisong (Auxis rochei), sunglir (Elagatis bipinulatus), lemadang (Coryphaena hippurus) as the main catch (Main catch). Whereas fish layang (Decapterus macrosoma), layaran (Istiophorus oriantalis), baby tuna (Euthynnus alletteratus)is a side  (by-catch). Keywords: composition of the catch, purse seiners, fishing season

Abstract

ABSTRACTThere were several human activities around the Sepinang Lake such as agriculture and palm plantation contributes the input of organic and anorganic matter that influence the type and abundance of phytoplankton. To understand the types and abundances of phytoplankton present in the Sepinang Lake, a researchhas been conducted in March-April 2018. There were three sampling points, namely in the inlet, in the middle of the lake, and in the end of the lake. In each sampling point,water was sampled from the surface and 2 Secchi depth. Samplings were conducted 3 times, once/week.Water quality parameters measured were temperature, transparency, depth, dissolved oxygen, CO2, nitrate, phosphate and pH.Results shown that there were 47 species of phytoplankton that were belonged to 5 divisions, namely Chrysophyta (10 species), Chlorophyta (25 species), Cyanophyta (8 species), Euglenophyta (3 species) and Cryptophyta (1 species). The phytoplankton abundance of the Sepinang Lake was 106,490 – 150,650 cells/L. The most common type of phytoplankton present wasMonoraphodium griffithii.Result shown that the temperature was 30.6-320C, transparency was 49.3-62.8 cm, depth was 211-223.6 cm, dissolved oxygen was 4.22-5.58 mg/L, CO2 was 11.32-13.32 mg/L, nitrate was 0.07-0.23 mg/L, phosphate was 0.09-0.23 mg/L and pH was 5.3-5.6. Based on the type and abundance of phytoplankton present, it can be concluded that the Sepinang Lake can be categorized as mesotrophic. Keywords: Kampar River, Oxbow Lake, Mesotrophic, Monoraphodium

Abstract

AbstractOn the coast of Mengkapan Village there is a mangrove forest covering an area of ± 30 Ha. The condition of mangrove forest has been changed due to domestic waste and oil spills.Secondary impact of mangrove ecosystem changes affect the associated organisms such as gastropods. To understand the community structure of gastropods in that mangrove ecosystem, a research was conducted on February-March 2018. The methods used in this research is survey method. There were 3 line transects and in each line there were 3 plots (1mx1m). The gastropods present in the plots were collected manually every two weeks. Results shown that there were 9 gastropods species present, they were Cassidula aurisfelis, Cerithidea obtusa, Cerithidea quadrata, Cerithideopsilla alata, Chicoreus capucinus, Indothais gradata, Littoraria melanostoma, Nerita lineata dan Telescopium telescopium. The gastropods abundance was ranged from 15-26 organisms/m2. The value of diversity index was (H') 2.46-2.81, the dominance index (C) was 0.17-0.24 and the uniformity index (E’) was 0.82-0.89. The water quality parameters are as follows: temperature was 25-28 0C, pH of the water was 7-6, pH of the soil was 6-7 and salinity was 22-260/00. Data obtained from this research indicate that the anthropogenic activities in the Mengkapan Village slightly affects the gastropod community. Keywords:Diversity Index, Dominance Index, Coastal Area,Line Transect, Anthropogenic

Abstract

ABSTRACT This research was conducted in July 2018 with the aim to determine the metal content of Zn, Cr and Cu in brown Algae (Sargassum sp.) From Bungus Waters of West Sumatra Province and to determine the value of Metal pollution index (MPI) in Bungus Waters of West Sumatra Province.Determination of sampling location using purposive sampling, namely by considering the state of the research area. Sampling was carried out in areas with relatively different anthropogenic activities and analysis of heavy metal content was carried out at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, University of Riau. The results showed that the Zn metal content in brown algae ranged from 55,033 - 70,250 µg / g, where the highest concentrations were at Station 3 and the lowest at Station 1. The concentration of Cr metal in brown algae ranged from 18,500 - 32,833 µg / g, where the highest concentration was found in Station 3 and the lowest at Station 1. The concentration of Cu in brown algae ranges from 2,833 - 7,500 µg / g, where the highest concentration is at Station 3 and the lowest at Station 1. The MPI value of Bungus Waters of West Sumatra Province is 19.44, the value is still normal when compared with research conducted in other regions using Algae samples.Keywords: Zn, Cr and Cu metals, Brown Algae (Sargassum sp.), Bungus waters
