Abstract

This research was conducted on 24-30 May 2016 in the Laboratory Fish Hatchery and Breeding Faculty of Fisheries and Marine Science University of Riau. The purpose of this study are to determine the influence of temperature (room temperature and 30°C) and dose of aquamate (0 mg/L and 20 mg/L) on fertilization, hatching and larvae survival of Pawas (Osteochilus hasselti C.V.). The method used in this study is an experimental method by using a completely randomized design with 2x2x3 factorial design. The first factor is the temperature (room temperature and 30°C), while the second factor is the dose of aquamate (0 mg/L and 20 mg/L) with three replications. Fish kept in the twelve unit of 30x30x30cm aquarium with the volume of water were 15 L each.The result showed that the treatment of the giving different temperature and oxygen to hatching the eggs and 5 days fish larvae initial survival of Pawas (Osteochilus hasselti C.V.) that is best for Fertilization Rate (FR) of Pawas eggs is room temperature with the addition 20 mg/L aquamate which produce figure conception amounted to 43.78%, figure Hatching Rate (HR) amounted to 63.24%, the rate of Survival Rate (SR) amounted to 96%. Data from water quality measurements during the study that is the temperature used is room temperature and 30°C, pH range 6-8. The levels of dissolved oxygen on dose of aquamate 0 mg/L namely 3.0 mg/L while on dose of aquamate 20 mg/L namely 7.0 mg/L. Dissolved oxygen was increased on dose of aquamate 20 mg/L as much as 4 mg/L after one day the addition of aquamate into aquarium.Keywords: temperature, oxygen, fertilization rate, hatching rate, survival rate, Osteochilus hasselti C.V.

Abstract

Research about abundance of planktonic diatoms with concentration ofnitrate and phosphate in Belawan waters of North Sumatra Province wasconducted in February 2013. The purpose of this study was to know the type ofplanktonic diatom, nitrate and phosphate concentration, diatom communitystructure, determine the relationship between nitrate and phosphate concentrationwith Abundance of diatoms. Samples taken from 4 stations. The sampleidentification was obtained by 16 diatom species. The abundance of diatoms is inthe range of 4,018-4,802 ind/liter. The nitrate concentration of each station is inthe range of 0.261-0.507 mg/l. The concentration of phosphate in the range of0.064-0.126 mg/l. The diversity index is moderate, no dominant type and theuniformity index belongs to the still-balanced waters. The relationship of nitrateand phosphate concentration to diatom abundance is classified as moderate topositive value, the higher the concentration of nitrate and phosphate, the higherthe diatom abundance.Keyword: Belawan Waters, Diatom, Abudance, Nitrate & Phosphate

Abstract

The sago industrial liquid waste is rich in TSS and ammonia and thus need to be processed before being flown to environment. A study aims to reduce the TSS and ammonia in that waste has been conducted in January - April 2017. The sago liquid waste (135 liter) was kept in an anaerob tank (with gravel, sand and palm fiber media) for 10 days. The waste was then flown to an aerobic tank (with charcoal and palm fiber media) for 5 days and finally the waste was treated in a phytoremediation pond that was completed by Pistia stratiotes for 15 days. By the end of the experiment, the TSS reduced from 376 mg/L to 30 mg/L (the effectivity was 88.84% - 92.02%), while the ammonia reduced from 11.82 mg/L to 0.01 mg/L (the effectivity was 48.48% - 99.7%). Other water quality parameters such as pH and DO were improved. The treated waste was used for rearing Cyprinus carpio fingerlings for 7 days and survival rate of the fish was 93%. Based on data obtained, it can be concluded that the combination of anaerob-aerob biofilters and phytoremediation using P. stratiotes is effective to reduce the TSS and ammonia content in the sago industrial liquid waste.Keyword: TSS, Ammonia, Biofilters, Pistia stratiotes

Abstract

Snakehead fish (Channa striata) is present in the Kulim River that has relatively good water quality, as well as in the Sibam River that has polluted water. To understand the reproductive biology of snakehead fish from those rivers, a study has been conducted from January to March 2017. There were 23 fishes from the Sibam River, and 53 fishes from the Kulim River. Results shown that the reproductive biology of the fish from those areas are different. In the Sibam River, the GSI of the male was 0.01-0.41 and that of the female was 0.12-4.38, with 0.8-1.2 mm egg diameter and 45,774-60,751 fecundity. While in the fish from the Kulim River, the male’s GSI was 0.03-1.82, the female’s was 0.07-6.04, the egg diameter was 0.8-1.6 mm and the fecundity was 16,027-88,648 eggs/fish. Data obtained shown that the water quality affects the reproductive biology of snakehead fish in general, as the reproductive biology of fish from the Kulim River is better.Keyword :Channa striata, GSI, maturity level, fecundity, Sibam River, Kulim

Abstract

 Abstract This research aims to know the conditions of fishermen and the fishing household strategy in the face of poverty. This research was carried out in April 2017 which is located in Teluk Kabung Selatan Bungus Teluk Kabung District of West Sumatra Province. The methods used in this research is a survey method with the total number of respondents as many as 30 people and the determination of the respondents conducted in simple random sampling. The condition of the fishing households experiencing poverty can be seen from the large amount of dependent families, home ownership status, the amount of expenditure that is greater than the amount of income received, and factors causing poverty that isfishing technology still traditional by using the machine ships with robin 5 Power Horse, owes the habit and isolate area geographically causes high costs incurred to make ends meet. Strategies used by fishermen in the face of poverty is by optimizing the labor of family members such as spouses and children, diversified jobs such as working on the peasants, workers and interisland transport service providers, as well as utilize loans to relatives in the family or neighbors. Keywords: household condition, strategy, fisherman, poverty, Teluk Kabung Selatan.

Abstract

Thynnichthys thynnoides is commonly inhabit the Pinang Luar Oxbow Lake. Information of the stomach content of this fish, however is limited. To understand the stomach content and its relation to size, sex and environmental condition, a research has been done on March to April 2016. There were 3 stations, around inflows of the Kampar River (St 1), at the middle of the lake (St 2), and the rear end of the lake (St3). Sampling was conducted 4 times, twice/month. Type of food present in the stomach of fish was analyzed and the PI (Preponderance Index) was calculated. There were 149 fishes captured and all of the fish were used in this study. Results shown that T. thynnoides is a plankton feeder, and there was no main food, but in general Cyanophyceae is the highest (PI37%) and the supplementary food was Protozoa (0.02%). In small fish, Euglenophyceae was 37%, while in the large fish Cyanophyceae was 39%. There are no differences of food type in male and female fishes.Keywords: Thynnichthys thynnoides, Stomach Content Analysis,Preponderance Index, Pinang Luar Oxbow Lake

Abstract

Osphrenemus gouramy or gurami fish is freshwater fish that live in thePinang Luar Lake. Population of that fish in the lake, however, is low andinformation on its biological aspect such as morphometric, meristic, and growthpattern is rare. A study aims to determine those aspects had been conducted inMarch 2017. There were 102 fishes, with 63.87-193.72 mm TL and 3.49-129.98gr BW. There were 25 morphometrical characteristics measured and 11 meristicalcharacteristics counted. The meristical characteristic of this fish as as follow :D.10-14, P.9-13, V.1-6, A.19-20, C.15-16, and the number of scales in the predorsalfin was 21-80, around the body was 37-76, in the caudal penducle was 8-31and in the lateral line was 20-42. The length-weight relationship shown thatgrowth pattern of the fish is positif allometric, b=3.070 in male, and b=3.032 infemale. The water quality parameters shown that temperature 27-29 oC,transparancy 36-42 cm, pH 5, DO 2-2.5 mg/L, CO2 6.9-7 mg/L and depth 150-520cm. Data on water quality parameters indicate that water quality in the PinangLuar Lake is able to support the life of gurami fish.Keywords: growth patterns, meristic, morphometric, Osphrenemus gouramy,Pinang Luar Oxbow Lake.
