Abstract

The purpose of this community service in term of IbM was to transfer the aquaculture technology such as sex reversal, immunostimulant, feed formulation and financial management training to fish farmer at Eris Village. The methods used included elucidation, explanation, training and field practice. The results showed that fish farmers actively participated in discussion and practicing the given subjects.  In addition, farmers were able to increase their skill and knowledge about how to produce male fish fingerling, how to formulate fish feed and immunostimulant and how to manage their financial. Products resulted through this service were appropriate according the standard criteria. Continuous guidance from university and government is required to ensure the success of this service activity.   Keywords: fish farmer, sex reversal, immunostimulant, fish feed, financial management, Eris Village

Abstract

The objective of this research was to evaluate the effect of feed supplemented with baker’s yeast on survival rate of nile tilapia larvae and to determine the effective dose of baker’s yeast that could optimally improve larval quality.  The research was conducted at Pathology and Clinic of Fish Disease from June – September 2014.  Fish as brood stock candidates was cultivated at five concrete tanks (2x1x1 m3) at a density of 30 fish per tank.  Each tank was equipped with water inlet, outlet and water pump for recirculating and aerating.  After seven days of adaptation, fish was fed pellet supplemented with baker’s yeast at five different doses (0, 10, 20, 30, 40 g/kg food) for four consecutive weeks at 4%/bb/day, twice daily.  Larva was captured with seser and moved into five glass aquaria with density of 20 larvae/aquarium and reared for two weeks.  Data collected was survival rate of larvae achieved until the end of larval rearing.  Research result showed that larvae produced by brood stock fed food supplemented with 10 g baker’s yeast per kg food had the highest survival rate namely 60%.  As conclusion, supplementation of baker’s yeast into brood stock feed might increase survival rate of larvae.   Keywords:  nile tilapia, baker’s yeast, larvae, survival rate

Abstract

The research intended to determine the optimal concentration of honey addition in sperm dilution to improve sperm motility, fertilization and eggs hatchability of goldfish (Cyprinus carpio). Experimental design used was a Complete Randomized Design (CRD) with four treatments each with three replications. The concentration of honey addition used for treatment were A (0 ml of honey in 100 mL of physiological NaCl), B (0,2 mL of honey in 99.8 mL of physiological NaCl), C (0.4 mL of honey in 99.6 ml of physiological NaCl), D (0.6 mL of honey in 99.4 mL of physiological NaCl). Sperm dilution containers used was 12 plastic cups and the container fertilization and hatching eggs container used was 12 brass plates.  Spermatozoa motility observation performed immediately after dilution process. Fertilization observation was performed after 12 hours of fertilization process, and Egg Hatchability observation was performed after 72 hours of fertilization.  The observation results showed that the addition of honey in sperm dilution contributed significant effect on spermatozoa motility, fertilization and eggs hatchability of goldfish (Cyprinus carpio). This observation showed that the addition of 0.6 ml of honey in a sperm dilution was the best treatment indicated by the average percentage of spermatozoa motility (80,00%), fertilization (84,00%) and eggs hatchability (82,33%).   Keywords: Honey, spermatozoa motility, fertilization, eggs hatchability, Cyprinus carpio L

Abstract

This study aimed to determine the effect of concentration of honey on masculinization of nile tilapia female. The study had four treatments, each with three replications. The experimental design used was completely randomized design (RAL).  Data was analyse using Analysis Of Variance (ANOVA) followed by LSD at 5% and 1%.  Broodstock was  soaked in 1 L of water with treatment A 0 mL (without honey), B (5 mL honey), C (10 mL honey), D (15 mL honey) for 10 hours. After soaking, fish was reared in pan for one month. The percentage of male was determine by comparing the length and width of the red blood cells under a microscope.  The results showed the the use of honey had significant effect on female masculinization.  The percentage of male larvae tended to increase with the increase of honey dose. The highest percentage of male was obtained in treatment D (15 ml) that was 80%.   Keywords: Honey, masculinization, larvae, Oreochromis niloticus

Abstract

This study was conducted to determine the effect of different doses of ovaprim on latency time of spawning, hatching rate, and survival of fish larvae (Pangasianodon hiphopthalmus). Experimental design used was Randomized Complete Design (CRD) with four treatments, each with three replication. The treatments including 0 ml, 0.3 ml, 0.6 ml and 0.9 ml ovaprim per kg of body weight of fish. Data collected consisted of latency time of spawning, hatching rate, and survival rate of larvae. The results showed that treatment with different doses of ovaprim hormones resulted in a significant influence on latency time of spawning, egg hatchability and survival rate of larvae. It was found that 0.6 ml ovaprim could increase the latency time of spawning, egg hatchability and survival rate of larvae. The average latency time of larvae was 529 minutes, hatching rate was 80,86% and survival rate of larvae was 83,33%.

Abstract

Vitamin C content in the ovarium of African Catfish (Clarias gariepinus) during reproductive cycle was investigated. One hundred twenty samples of females covering different stages of reproductive cycle were collected from fresh water ponds. The fishes were sacrifized and the ovarium were collected for analysis of gonad maturation stage (TKG), oocyt structure and vitamin C content in the ovarium.  Results indicated that average of vitamin C content of ovarium at stage I was 74.33mg/g (wet weight). The maximum content was found in stage III at level of 155.98mg/g (wet weight) and afterwards in the next stage vitamin C content decreased. The maximum of oocyt stadium 3 (oocyt vitelogenesis) was also found at this stage III. The findings indicate that vitamin C has a role in the reproductive cycle of catfish and its content is related to ovarium development and oogenesis.

Abstract

This study was aimed to determine the effect of the dilution ratio of sperm with optimal NaCl and fructose on the motility of the catfish, Clarias sp., spermatozoa, fertility and hatchability of eggs. Catfish used in this study consisted of one parent pairs (male and female weight of 1000 grams weight of 1500 g). NaCl and fructose solution were diluted with aquabidest. The observation was conducted on the motility of spermatozoa, fertility and hatchability of eggs. The experimental design used completely randomized design (CRD). Dilution ratio is 1: 0, 1, 20, 1: 40, 1; 60, 1: 80, and 1: 100 with replicated 3 times. Observations were carried out soon after the sperm mixed with diluents. Fertility occurred 12 hours after fertilization. Egg hatchability was observed after fertilization. The results showed that the ratio of dilution gave significant effect on the sperm motility, fertility and hatchability of the eggs. This research found that the dilution ratio 1: 60 was the best treatment with the average sperm motility of 96. 66%, fertility of 71, 66 5% and egg hatchability of 70%.
