Abstract

This research was conducted from May 23 to December 6 2015. The aim of this research was to determine the effect of ovaprim doses on spawning success of lelan fish (Osteochilus pleurotaenia Blkr). The method used in this research was an experimental method with Completely Randomized Design (CRD) with one factor, four treatments and three replications. The treatment used in this research was an injection of ovaprim with different doses i.e : P0 (0,2 mL NaCl physiology 0,9 %/kg of body weight), P1 (0,5 mL/kg of body weight), P2 (0,6 mL/kg of body weight) and P3 (0,7 mL/kg of body weight). The results showed that ovaprim dose of 0,6 mL/kg of body weight was the bestin turn of latencytime (6.08 hours), total eggs stripping (30.024 eggs/g gonads), egg diameter (0,827 mm), egg maturity (84,443%), Ovi Somatic Index (20,15%), fertility rate (20,01%), hatching rate (19,43 %), and survival rate (29,93 %). Keywords : Ovaprim, Spawning, Lelan (Osteochilus pleurotaenia Blkr).

Abstract

This research was conducted on June 2015 in mangrove ecosystem of Liong River Estuary, Bantan District, Bengkalis Regency. The purpose of this research is to know abundance, distribution pattern and sex ratio of Lokan Bivalve (Polymesoda expansa). The method used was survey by observing, measuring and taking sample directly on research site. The research site was determined by purposive sampling which consisting of 3 stations, specified by mangrove densities. The result showed that average abundance were 0.44-1.66 ind/m2. The highest abundance was at Station 1 and the lowest was Station 3. The distribution pattern based on Morisita Index was aggregated. The sex ratio showed that difference among male and female at station 1 and 2, where the percentage of female was more dominating. While, sex ratio was balance on Station 3.Key words : Abundance, Sex Ratio, Distribution Pattern, Polymesoda expansa

Abstract

This study aims to determine the abundance, size distribution of Cerithium rostractum shells used Birgus in coastal waters of the Sungai Nipah in West Sumatra. This study was conducted in June 2015. Birgus was obtained from three different stations. The results showed that at the first station had the highest average of abundance is 13333.33 ind / Ha and the lowest average of abudance at station III that was 2266,667 ind/ Ha. There were 5 Birgus species namely B. rugosus, B. perlatus, B. perlatus, and species B. brevimanus with pereent abudance of 4.32% -61.11%. Shell size used by Birgus were grouped info 4 groups, namely the size of group 1 (<50mm), group 2 (50-80mm), group 3 (81-100mm), and group 4 (>10mm). Birgus shell size that is used most dominant came from size of 51-80mm and 81-100mm, in all station. The overall distribution pattern in the study site was 1.02 -1.71, meaning the tipe of distribution was spread clustered. Result of the F test on abudance showed a significant difference. The value of environmental parameters measured were in the range of : temperatures 29-30.5 0C, pH 7, salinity 30-32 ‰, and transparency of 100%. The parameter values is still were all still supporting to Birgus life.keyword: Birgus, abundance, shell size, Cerithium rostractum, distribution pattern, and Sungai Nipah

Abstract

Tor soro is a North Sumatran endemic species. This fish have high economic value and play important role in Batak’s culture. Biological information on this fish, including the morphological characteristic, however, is rare. To understand the information on length-weight relationship, a study has been conducted from March to June 2015. The fish was sampled from the Aek Godang River, especially in the Banuaji (St 1) and the Dolok Nauli (St 2) villages. Totally 123 fish were captured. Several body parts such as total length, head length, fork length, caudal rod length, body height and body weight were measured and then compared to standard length in order to understand the growth pattern of the fish. Results shown that the length-weight relationship of male and female was isometric (male b=3.039 and female b=3.024). The coefficient correlation (r) values of the relationship between standard length and other body parts ranged from 0.812-0.994. It’s indicate that there is very significant relationship between standard length and the length of other body parts.Keyword: Tor soro, lenght-weight relationship, Aek Godang River, North Sumatera Province

Abstract

Pterygoplichtys pardalis has known as sapu-sapu fish. It is commonly present in the Air Hitam River. To understand the reproductive biology of this fish, a research has been conducted on February to May and November 2015. Fish samples were obtained from the Air Hitam River. Parameters investigated were fish morphology, sex ratio, maturity level, fecundity and the relationship between fecundity, length and weight. Samplings were done at three stations, in the in the upstream (Station I), middle (Station II), and downstream (Station III) of the river. Totally 169 fishes (75 males and 94 females) were captured. Sex ratio between male and female was 1:1.2. The Gonado Somatic Index (GSI) of male was 0.0022% -2.6% and that of the female was 0.03-3.4%. Egg diameter was 1.5 -3.2 mm. The fecundity is around 5,351-48,980 eggs/fish. The relationship between fecundity and standart length was y= 2.056x -0.548, fecundity and body weight was y= 0.863x +2.290. The water quality parameters are as follows: temperature 27-28.5°C, turbidity 15-22 NTU, the depth of the water 0.75-0.80 m, the width of the river 8.06 m, current speed 0.15-0.44 m/s, pH 6-9, DO 2.5-3 mg/L. Data on water quality parameters indicate that water quality in the Air Hitam River is able to support the life of the fish and the fish may reproduce well.Keyword: Pterygoplichtys pardalis, reproduction, sex ratio, GSI, fecundity, Air Hitam River

Abstract

Averrhoa bilimbi juice contain s that can reduce organik matter, turbidity and color to improve peat water quality. A research aims to understand the effectiveness of A. bilimbi juice to improve peat quality water was conducted on May – October 2015. The method applied was RBD with 4 different concentration of A. bilimbi juice: P0 (0 mlL-1as control), P1 (30 mlL-1), P2 (35 mlL-1) and P3 (40 mlL-1) and different sampling time, first day (D1), second day (D2) and third day (D3). Parameter measured were turbidity, organik matter and color. These parameters were measure in the research showed that edition of Averrhoa bilimbi juice can reduce organik matter, color and turbidity. In the first day (D1) the best treatment was P3D1, as the turbidity reduced from 805 NTU to 34.9 NTU, organik matters from 1590.5 mg/L to 603.7 mg/L and color from 19010 PtCo to 1037 PtCo. In Second day (D2) the best treatment was P3D2, the turbidity reduced from 901.5 NTU to 33.5 NTU, organik matters from 1303 mg/L to 365.9 mg/L and color from 16.555 PtCo to 894 PtCo. In third day (D3) the best treatment was P2D3, the turbidity reduced from 855 NTU to 38.7 NTU, organik matters from 1135 mg/L to 231.4 mg/L and color from 23.400 PtCo to 669 PtCo. The highest survival rate of Cyprinus carpio and Oreochormis niloticus that were reared in the treated water for 4 days was in the P1 (70 %).Keyword: Peat water, Averrhoa bilimbi.
