Abstract

ABSTRACT The aims of this research was to study Gonad Maturity Level (GML), Index Gonado Somatik (IGS), absolute fekundity and egg diameter of Channa striata injected with the Human Chorionic Gonadotropin hormone. The research was conducted in 26th of December 2013 until 26th of January 2014 at the Fish Hatchery Unit (FHU) Batanghari Sembilan, North Indralaya District, Ogan Ilir, South Sumatra. Channa striata which as used had weights 85-105 gram per fish. The experiment was arranged in a Completely Randomized Design (CRD), (P0) No injection of HCG, (P1) 200 IU per kg fish, (P2) 250 IU per kg fish, (P3) 300 IU per kg fish. Parameters observed Gonad Maturity Level (GML), Index Gonado Somatik (IGS), absolute fekundity and egg diameter. From the four treatment experiment, P3 treatment produced the highest GML V whose the percentage was 20%, while P0 treatment did not reach GML IV and V, most of the P0 treatment (80%) only reached GML II. Based on further test of Duncan Signipicant Differences with 95% credibility level, the IGS data of Channa striata was significantly different and influential among treatments, the smallest IGS was produced from P0 treatment that is 0.43% while the largest IGS was produced from P3 treatment that is 5.91%. The smallest absolute fecundity was on the P0 treatment which was 582 eggs while the largest was on P3 treatment that is 5,775 eggs. The smallest egg diameter was on the P0 treatment which was 0.35 mm while the largest was on P3 treatment that is 0.93 mm. Hormone HCG injections of 300 IU per kg weight of the fish proved to be finalizing a Channa striata gonad.   Keywords : Channa striata, HCG hormone, GML, IGS, egg diameter

Abstract

ABSTRACT The use of extract root ginseng in the process of Betta fish masculinization is expected to increase the testosterone. The purpose of this research is to determine the effect ginseng root extract to the percentage of the male betta fish by masculinization. This study has been conducted at the Basic Aquaculture Laboratory, Faculty of Agriculture, Sriwijaya University. This study use a completely randomized design with 4 treatments and 3 replications. The treatments in this research was betta fish larvae aged 7 days that submersed on ginseng root extract media with different concentration for 8 hours. The treatment were the addition of ginseng root extract as much as 1 mg/L (P1), 2 mg/L (P2), 3 mg/L (P3), 4 mg/L (P4) and without ginseng root extract addition as control (P0). Parameters observed consist of percentage of betta fish male, survival rate and quality of water. The result of this research shows that the addition of extract panax ginseng with difference concentration has significant effect to male betta fish percentage, but there is no a significant effect on survival rate. Treatment P3 with concentration 3 mg/L is the best result, it produced 95.05% of male betta fish after immersion for 8 hours. Keywords : Betta fish, Ginseng root extract, Immersion, Masculinization

Abstract

ABSTRACT The problem of development of climbing perch culture was low in growth rate. The effort to increase growth rate of climbing perch is hormonal treatment, including the hormone thyroxine. The aim of this research was to determine the effective consentration and duration of immertion of thyroxine hormone to increase yolk sack absorbtion and growth rate. This research held in August to September 2014 in Laboratorium Dasar Perikanan, Aquculture Study Departement, Faculty of Agriculture, Sriwijaya University, Indralaya. This research using factorial completely rondomezed design with two factors, the first was thyroxine consentration with immersion media (K1=0.01 mg.L-1, K2=0.05 mg.L-1, K3=0.1 mg.L-1) and the second was the long immersion (W1=24 hours, W2=48 hours, W3=72 hours) with three replication. The parameters that observed were yolk sack absorption, growth, survival rate and water quality. The result showed that the highest yolk sack absorbtion was K2 (0.05 mg.L-1) and K3 (0.1 mg.L-1). The highest growth was K3W2 (0.1 mg.L-1 of consentration and immersion for 48 hours) with the weight was 316.1 mg and length was 26.56 mm. The best survival rate was 88.67% (K1W1). The value of water quality during larva rearing were temperature 26-28 oC, pH 5.6-6.5, dissolved oxygen 4.43-5.93 mg.L-1 and ammonia 0.00-0.03 mg.L-1   Keywords : Climbing perch larvae, thyroxine hormone, duration of immertion, growth

Abstract

ABSTRACT The purpose of this study was to determine the effect of different incubation temperatures to the rate of the kissing gouramy (Helostoma temminckiiC.V) yolk absorption, and to know the right time to start feeding in the larval stage. This study was held on January 09th to 13th, 2013 using Completely Randomized Design (CRD) with five treatments namely P1 (26±0.50C), P2 (28±0.50C), P3 (30±0.50C), P4 (32±0.50C) and P5 (34±0.50C).Each treatment was repeated three times. The results showed that the temperature gave significant effect (P>0,05) to rate of yolk absorption, periode of yolk absorption and percentage of larval survival.The highest rate of yolk absorption was P5 (42.24 x 10-5 mm3/hour), but not significantly different fromP4 (41.63 x 10-5 mm3hour-1), and P3 (41.83 x 10-5 mm3hour-1). The fastest periode of yolk absorption was P5 (72 hours) and the longest was P1 (78.67 hours). While the highest larval survival rate was found on P3 (89.87%), on the other hand the lowest survival rate was found on P5 (62.35%). The natural feeding of kissing gouramy fish should be started at 74th hours (3 days, 2 hours) after hatching and larval rearing should use temperature of 300 ± 0.50 C.   Keywords: Helostoma temminckii C.V., temperature, yolk absorption

Abstract

ABSTRACT The success in egg hatching is determined by internal and external factors. One of external factors is the acid level. The use of pH in egg hatching is to stimulate chorionase enzyme that can make chorion become soft. The purpose of this research is to determine the best pH value for hatching of snakehead eggs. This research had been conducted in Laboratorium Dasar Perikanan, Departement of Aquaculture, Agriculture Faculty, Sriwijaya University on January until February 2016. The research method used a completely randomized design with five treatments and three replications. The treatment were P1 (pH 5±0.2), P2 (pH 6±0.2), P3 (pH 7±0.2), P4 (pH 8±0.2) dan P5 (pH 9±0.2). The results showed that different values of water pH in snakehead hatching gave significant effect on hatching percentage, incubation time and survival rate of larvae but did not indicate  significant effect on percentage of abnormal larvae. The highest hatching percentage was in treatment P5 (90.75%), the fastest incubation time was in treatment P4 (20.00 hours), the highest survival rate of larvae was in treatment P2 (85.31%) and the highest percentage of abnormal larvae was in treatment P1 (1.67%). During the research, water quality were in tolerance range for hatching and snakehead larvae rearing where DO (5.27-6.01 mg/l), ammonia (0.00-0.29 mg/l), and alkalinity (26-106 mg/l).   Key words : Snakehead, Hatching, pH different

Abstract

ABSTRACT             Climbing perch (Anabas testudineus) is a kind of swamp fish which is potentially to be cultivated. Photoperiod is one of factor that influence growth from culture fish larvae. Light also influence growth hormone and make larvae easier to eat their feed because larvae usually visual feeder. The aim of this research is to determine the best photoperiod in larvae of age 3 ? 27 days so as to generate growth and survival rate climbing perch of larvae highest in aquarium with defferent of photoperiod. The usage of the research are expected that different photoperiod can influence the growth and survival of climbing perch larvaes. The research was conducted on April - May 2016 in Laboratory of Budidaya Perairan, Faculty of Agriculture, Sriwijaya University. This research methods used completely randomized design (CDR) with use six treatments and three replications of photoperiod those are P1(24L:0D), P2(18L:6D), P3(12L:12D), P4(6L:18D), P5(0L:24D). The parameters of this research are growth, survival rate of climbing perch larvae and maintenance of water quality. The result showed that photoperiod has significant effect of survival rate, weight growth and length growth from climbing perch photoperiod for 24 hours each day  (treatments P1) has the highest result for survival rate and growth 81.11%±2.01%,  30.68mm±0.14mm, 0.46g±0.04g. The value of water quality during larvae rearing were temperature 27 ? 31 oC, pH 5.70 ? 7.10, dissolved oxygen 4.56 ? 7.58 mg.L-1 and ammonia 0.02 ? 0.11 mg.L-1. Keywords: Climbing perch, Growth, Photoperiod, Survival rate

Abstract

The condition of 90Sr concentration in the East China Sea and North Pacific closed to the Japanese island has been measured from 3 ? 31 July 2000. There were differences condition of 90Sr concentration in the those locations. The concentration of 90Sr detected in the surface East China Sea and North Pacific ranged 0.44?1.32 mBq/? and 0.66-1.38 mBq/? respectively. Generally, the condition 90Sr concentration in the East China Sea was lower than in the North Pacific. The highest 90Sr concentration occurred in the off shore of North Pacific, because the 90Sr in the open sea is dominantly from nuclear weapon testing and nuclear power plant accident (Chernobyl) rather than other resources, and it take long time to precipitate into the bottom. Kuroshio and Taiwan-Tsushima warm current systems influenced importantly in distribution of 90Sr concentration in the East China Sea beside other physical factors such as fishing activity. These currents were not strong enough to stimulate increasing 90Sr concentration in the coastal region of North Pacific close to the Japanese islands.
