Abstract

The purposes of research were to determine the survival and growth of catfish larvae (Clarias sp) produced from eggs using honey in sperm dilution.  Sperm dilution was prepared by disolving honey (0 mL; 0,6 mL; 0,65 mL; dan 0,7 mL) in 100 mL, 99,4 mL; 99,35 mL dan 99,3 mL NaCl respectively. The research was conducted using Complete Randomized Design (CRD) with four treatments each with three replications. Research results showed that survival of larvae at treatment D was the highest (81,33%), followed by treatment C (75%) and B (72%) and the lowest was treatment A (63.67%). The highest absolute length growth was achieved at treatment D (1.73 cm) followed by treatment C (1.40 cm), B (1.10 cm) and the lowest was treatment A (1.03 cm). It could be concluded that supplementation of honey in sperm dilution influenced the survival and growth of catfish larvae Keywords: honey, Clarias sp, sperm dilution, survival, growth

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

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 best combination of feed on the growth and survival of larval fish catfish (Clarias gariepinus). This study  used completely randomized with six treatments including treatment A: Artemia, B: Tubifex C: Pellet, D:  combination of (50%) Artemia + (50%) Tubifex, E:  combination of (50%) Artemia + (50%) Pellet, and      F:  combination of (50%) Tubifex + (50%) Pellet. Each treatment consisted of three replications. The result showed that the combination of  50% artemia + 50% tubifex could promote the growth length of larvae of 4,003 cm, weight of larval of 0.633 g,  and larval survival was 79%.  This combination was the best combination for the growth and survival of catfish larvae.   Keywords: Combination of feed, Clarias gariepinus, larvae, growth, survival

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
