Abstract

ABSTRACT             Nygard Index can be used to determine the trophic state of waters. Calculation of this index is based on the number of phytoplankton species that are belonged to these following groups, namely Chlorococcales, Euglenophyceae, Centric diatom, Myxophyceae and Desmidiaceae. To understand the trophic state of the Sepinang Lake, a research has been conducted  on March – April 2018. There were 3 sampling points, namely in the inlet, in the middle of the lake and in the end of the lake. In each sampling point, water samplet from the  surface and 2 secchi depth. Sampling was done three times, once/week. Water quality parameters measured were phytoplankton, transparency, temperature, pH, nitrate, phosphate, Disolved oxygen and free carbondioxide. Results shown that there were 48 species of phytoplankton present, namely Desmidiaceae (10 species), Euglenophyceae (10 species), Chlorococcales order (14 species), Centric Diatom (5 species), and Class Mixophyceae (1 species). The water quality parameters were as follows: transparency49,3-63 cm, temperature 30,6–32,00;, pH 5.33-5.53, nitrate 0,08-0,17 mg/L, phosphate 0,10-0,18 mg/L, dissolved oxygen 4,63-5,04 mg/L, free carbon dioxide 11.32-13.32 mg/L. Nygaard Index value of the Sepinang Lake was 1.8-2.5, indicates that the Sepinang Lake is mesotrophic to eutrophic. Keywords : Oxbow Lake, Phytoplankton, Mesotrophic, Eutrophic.

Abstract

AbstractPekak Lake is one of oxbow lakes located in the Buluh Nipis Village. A research aims to understand the limnological condition of the Pekak Lake based on physical – chemical parameters has been conducted in March-April 2018. There were three sampling stations namely Station 1 (inlet), Station 2 (in the middle of the lake), and Station 3 (outlet). In each station there were two sampling points, in the surface (0 cm) and 1 Secchi depth (75 cm). Samplings were done once/week for 3 weeks period. Water quality parameters measured were temperature, transparency, depth, pH, DO, CO2 free, nitrate and phosphate concentration. Result shown that the temperature 28.6-300C, transparency 68.5– 76.83 cm, depth 1.45 – 2.70 m, pH 5 , DO 5.13-6.4 mg/L, CO2 free 8.23-15.48 mg/L, nitrate 0.05 – 0.19 mg/L and phosphate 0.06 – 0.11 mg/L.  Based on the nitrate and phosphate concentrations, Pekak Lake can be categorized oligotrophic- mesotrophic. Keyword : Oxbow Lake, Water Quality, Oligotrophic, Mesotrophic

Abstract

ABSTRACTThis reseach was conducted in March-June 2018 in Fish Diasease and Parasite Laboratories and Experiment of the faculty of Fisheries and Marine Science University of Riau. The purpose of this study was to determine the effect of the description of red blood (total erythrocytes, hemoglobin, and hematocrit) and the growth of catfish (Pangasius hypopthalmus). The method used was experiment with Completely Randomized Design (RAL) with one factor, the level 5 treatments and 3 replications. The treatment in this study is, P0: control without given, P1 (addition of propolis in feed at a dose of 600 ppm/kg), P2 (700 ppm/kg), P3 (800 ppm/kg), P4 (900 ppm/kg). The parameters measured were total erythrocytes, hemoglobin levels, hematocrit values, absolute weight growth, fish survival, and water quality. The results showed that feeding containing propolis given for 60 days in catfish (Pangasius hypophthalmus) gave a significant effect on the number of erythrocytes, hemoglobin levels, hematocrit values, absolute weight growth with P <0.05 and not significantly different from fish survival P> 0.05. The best treatment at the dose of P3 (800 ppm) with total erythrocytes 276 x 104cells / mm3, hemoglobin levels of 10.6 g / dL, and hematocrit levels 33.3%, and absolute weight growth of 39.18 gr, and survival of 98 %. The results of measurements of water quality during the study were temperatures ranging from 27-310C, DO ranged from 3.4 to 3.9 ppm, pH ranged from 5.2 to 7, and NH3ranged from 0.017 to 0.024 ppm.Keywords: Propolis, Haematology, Pangasius hypopthalmus

Abstract

ABSTRACTHampala macrolepidotacommonly inhabit the Lubuk Siam Lake. A research aims to understand the standing stock, relative growth rate and recruitment pattern of H. macrolepidota  in that lake was conducted in March 2018. Fish was sampled everyday for a week period, in 3 sampling points (in the flow of water enter the lake, in the middle of the lake and at the end of the lake), using gill nets. The standing stock was analyzed using Leslie method, while the relative growth rate and recruitment were analyzed using FISAT II software. Result shown that the standing stock of the fish was 339 kg, (L∞316.05 mm), K 0.54/year and t0 -0.0141/year. Recruitment percentage in March was 6.33% and the highest predicted recuritment was in May (19.6%). Keywords: Leslie method, Recruitment, Growth rate, Hampala barb

Abstract

Abstract Sail River has been polluted by heavy metals and those may affects the organs of aquatic organisms, including Notopterus notopterus. To understand the Cd and Fe content in the livers, kidneys and bones of the fish, a study has been conducted on January to February 2018.Samplings were conducted two times, once/month, in the downstream of the river. The fish samples were obtained from fishermen. Heavy metals content were analyzed using AAS.Results shown that the concentration of Cd in liver, kidney and bone were  1.178;0,956 and0,698 mg/kg,whilethose of  the Fe were 1,131;1,177 and 0,948 mg/kg respectively. Data obtained indicate that the fish from the downstream of the Sail River were already contaminated with Cd and Fe. Keywords:cadmium, iron, aquatic organism, fish organ

Abstract

ABSTRACT                The study aimed to observe the effect of different smoking temperature on the quality of skipjack (Katsuwonuspelamis) katsuobushi and to determine the best smoking temperature. The method used was an experimental and composed as non-factorial randomized complete design (RCD). The smoking temperature was differentiated into 3 levels of treatment, namely: of 40-50o C, 65-75o C and 90-100o C. The parameters used to assess the quality of katsuobushi produced were organoleptic test, water content, ash content, pH value, total plate count of microbia and fungal identification. The results showed that the best smoking temperature to produce the highest quality of skipjack katsuobushi was 90-100o C. It was shown by the highest value of appearance at 7.7 characterized by quite clean, slightly shiny without cracks, odor value at 7.8 characterized by specific wood fish odor reduced without additional odor, texture value at 7.4 characterized by hard and not easily broken, and taste value at 7.9 characterized by tasty and less tasty. The best katsuobushi contained of water 14.9%, ash 7.8%, pH value 5.4, phenol content 0.02 ppm, and TPC of bacteria 2.5 x 103 Cfu/g sample. The type of fungus grown on the skipjack tuna katsuobushi was Aspergillus sp.Keywords : katsuobushi, skipjack, smoking, temperature

Abstract

Abstract Ompok hypophthalmus is one of freshwater fish that inhabit the Tarai River. To understand the type of food consumed by O.hypophthlamus, a study has been conducted on April-June 2018. The fish was captured using a gill net and a scoop net. There were 105 fishes captured, that was consisted of 77 fishes with filled stomach and 28 fishes with empty stomach. Stomach content of the fish was analyzed as a basis to calculate the Preponderance Index (IP). Results shown that TL of the O.hypophthalmus ranged from 72 to 211 mm and BW ranged from 2.31 to 45.32 gram. The main food of O.hypophthlamus was insects (53%), the complementary food was fish (21%), and the additional food was unidentified debris (10%), molusca (9%), and crustacean (7%). Keywords :Sheatfish, fish food, Index of Preponerance, Carnivore fish
