Abstract

This research was conducted in Maret until Mey 2017 in Fish Hatchery and Breeding laboratory, Faculty of Fisheries and Marine Sciences University of Riau. The aim of this research was to determine the effect of combination ovaprim and oksitosin on ovulation and hatching of catfish (Mystus nigriceps). The method used in this research was an experimental method with Completely Randomized Design (CRD) with one factor, five treatments and three replications. The treatment used in this research was an injection of combination ovaprim and oksitosin i.e. P0 (100% ovaprim), P1 (25% oksitosin + 75% ovaprim), P2 (50% oksitosin + 50% ovaprim), P3 (75% oksitosin + 25% ovaprim), P4 (100% oksitosin (0,7 ml/kg). The results showed that the best in treatment combination ovaprim and oksitosin (P3 = 75% oksitosin + 25% ovaprim) which produce latency (6.03 hours), total eggs stripping (276 eggs/gr broodstock), Ovi Somatic Index (7.9 %), egg diameter increment (0.037 mm), egg maturity increment (7,6 %), fertilate rate (36%), hatching rate (52%), and survival rate of 5 days (61%).Keywords : Ovaprim, Oksitosin, Ovulation, and catfish (Mystus nigriceps)

Abstract

ABSTRACTNygaard Index can be used to determine the trophic state of waters. Calculation of this index is based on the number of phytoplankton species in these following groups, namely  Desmidiaceae, Myxophyceae, Chlorococcales, Centric diatom, Pennate diatom and Euglenophyceae. To understand the trophic state of the Lubuk Siam lake, a research has been conducted in February - March 2017. There were three sampling stations, namely station 1 (inlet area), station 2 (the middle of the lake) and station 3 (outlet area). In each station there were three sampling points, in the surface, 2 secchi depth, and 3 secchi depth. Sampling were conducted 3 times, once/week. Water quality parameters measured were phytoplankton (species and abundance), transparency, temperature, pH, nitrate, phosphate, Dissolved oxygen and free carbon dioxide. Results shown that there are 53 species of phytoplankton present, namely Desmidiaceae class (11 species), Myxophyceae class (6 species), Chlorococcales ordo (23 species), Centric   diatom ordo (6 species), Pennate diatom (5 species) and Euglenophyceae division (2 species). The water quality parameters were as follows: transparency 63-89 cm, temperature 28.5-30.53 0C, pH 6.83-7.27, nitrate 0.7-0.17 mg/L, phosphate 0.12-0.16 mg/L, Dissolve oxygen 4.10-7.84 mg/L, free carbon dioxide 5.29-15.98 mg/L. Nygaard Index value of the Lubuk Siam Lake was 2.1 – 2.83, and it can be  categorized as mesotrophic to eutrophic. Keywords: Lubuk Siam lake, Nygaard Index, phytoplankton, trophic state

Abstract

This research was conducted in October 2016 until January 2017 by using survey method. The purpose of this research was to determine the water quality, the structure of phytoplankton community and the relationship between the water quality with the abundance of phytoplankton in Sungaitohor Estuary Kepulauan Meranti District, Riau Province. Identification and analysis of phytoplankton was conducted at Marine Biology Laboratory Faculty of Fisheries and Marine University of Riau. The correlation regression analysis showed that the relationship between pH and phytoplankton abundance were very low, meanwhile correlation regression analysis between salinity and phytoplankton abundance was fair. The abundance of phytoplankton ranged between 25 - 75 ind/l, diversity index (H ') ranged from 0,81 – 1,89 (medium category), uniformity index (E) ranged from 0,12 – 0,30 (low category) and dominance index (C) ranged from 0,29 – 0,67 (medium category). The identification found 11 genera of phytoplankton i.e. : Leptocylindrus, Protoperidinium, Trichodesmium, Isthmia, Gonyaulax, Nitzschia, Cestum, Skeletonema, Thalassiosira, Stephanopyxis and Streptotheca. Protoperidinium was found in each stations.Keywords : Phytoplankton, Community Structure, Sungaitohor.

Abstract

This study were conducted in survey method. Four stations were established with three replication of each sampling station. It revealed that oil content in water ranged from (0.4391 – 0.7973) ppm. The highest epiphytic diatom density on the seagrass leaves oppeared in station 4 which accounted 366 ind/cm2, while the lowest 132 ind/cm2 found in station 2. During the study, epiphytic diatom species most commonly found are Isthmia sp, Navicula sp, Skeletonema sp, Ulothrix sp, dan Synedra sp. Statistical analysis showed the oil content and epiphytic diatom density correlation were weak with coefficient of (0.05)Key words : Rupat Utara Water, Oil Content, Epiphytic Diatom

Abstract

Featherback fish (Notopterus notopterus) is a type of freshwater fish that inhabit theSail River. This fish has high economic value, the price is more than Rp 60.000/kg.Information on biological aspects of this fish, including morphometric, meristic, andgrowth patterns is rare. To understand the those characteristics, a research had beenconducted from March-April 2017. There were 100 fishes (116-299 mm TL and 8.6-234gr BW) captured from the river. There were 23 morphological characteristics measuredand 8 meristical characteristics counted. The meristical characteristics were as follows:D.6-7, P.11-14, V.1, A.99-111, the number of scale in the pre-dorsal fin was 102-103,around the body was 126-136, in the caudal peduncle was 12-14, and in the lateral linewas 150-168. The length-weight relationship shown that the growth of male and femalewas positive allometric (b= 3.363). The water quality parameters shown thattemperature 28-30°C, transparency 5.50-14.83 cm, pH 5-6, DO 2-3.8 mg/L, CO2 11.9-21.9 mg/L and depth 0.7-1.8 m. Data on water quality in the Sail River is able tosupport the life of the N. notopterus.Keywords: Notopterus notopterus, Sail River, morphometric, meristic, growth patterns
