Abstract

This study was conducted over three months in the laboratory of Fish Diseases and Parasites, Faculty of Fisheries and Marine Sciences University of Riau Pekanbaru. The purpose of this research was to determine the structure of (Mystus nemurus) liver that were immersed with Curcuma xanthorrhiza ROXB extract and were infected by Edwardseilla tarda and to find out best dose Curcuma xanthorrhiza ROXB extract for the prevention of Edwardsiella tarda infections. The method used is an experimental method at a dose of treatment and analyzed descriptive. The treatment used is an extract of Curcuma xanthorrhiza ROXB with different concentrations, they were: Kn (Fishes were not receive any treantent), Kp (Fishes were not receive any treatment but were infected with E. tarda), P1 (immersed in curcuma with concentration 0,2 g/l), P2 (immersed in curcuma with concentration 0,4 g/l), P3 (immersed in curcuma with concentration 0,6 g/l) and were infected with E. tarda (0.1 ml of 108 of E. tarda), Fish organ (liver) were processed for histological studied (formalin fixed, alcohol series, 6 sliced and HE Stained). Result indicate that the structure of liver of the treated fish showing abnormality symptoms, such as necrosis, congestion, fatted degeneration and hemorrhage. From these, it can be concluded that immirsion in Curcuma with 0.6 g / l concentration is capable of inhibiting bacterial Edwardsiella tarda.Key word : Liver, Mystus nemurus, Curcuma xanthorrhiza ROXB, Edwardsiella tarda

Abstract

(Ocimum sanctum L)extract solution used for hibernating tilapia during drysystem transportation. The research was using an experimental method anddesignedrandomized complete design (RCD). The treatment was hibernating thefish by using four kinds and levelsof the concentrationruku-ruku leaves extract,namely: using cold temperatures 10oC (L0), the solution of ruku-ruku leavesextract at the concentration of 10% (L1), 15% (L2), 20% (L3). Parametersobservedwere the quality of the water used during hibernation (temperature, pH, turbidity,CO2 content), the activity of tilapia during hibernation, the changing conditionsoftilapia during transportation, the temperature fluctuations in the packaging box, aswell as the percentage of survival rate of tilapia after awakening. The resultsshowed that the best treatment was the using of ruku-ruku leaves extract at theconcentration of 20% to hibernate the tilapia fish in 15-20 minutes. The mortalityrate of life of tilapia was up to75% during 6 hours transportation.Key words: dry system transportation, foam media,hibernation,leaves extract,Oreochromis niloticus, Ocimum sanctum.

Abstract

This study was conducted in March 2016 in the waters of Kuala Tanjung,BatubaraDistrict, North Sumatra Province. General objective of this study wastodetermine the general condition of the aquatic environment Kuala Tanjung, andin particular is to know the type and abundance of macrozoobenthos, then therelationship of sedimentary organic matter content with abundance ofmacrozoobenthos. The method used in this research is survey method. Analysisresult done moderate polluted water conditions through the value through thevalue of diversity index (H ') ranged from 1.67 to 2.58. Dominance index value(C) ranges from 0.19 to 0.37. Value uniformity (e) ranges from 0.39 to 0.57.Macrozoobenthos were found as many as 9 species of gastropod class, and 3species of bivalves class. Abundance obtained ranged 32- 112 ind / m². Therelationship between the sedimentary organic matter content with abundance ofmacrozoobenthos obtained regression equation y = 46.18 + 1.576x with acoefficient of determination (R2) of 0.407 and a correlation coefficient (r) of0.638. This means that the relationship between the organic matter content ofsediment with an abundance of macrozoobenthos was moderately.Keywords: OrganicMaterials, macrozoobenthos, sediments and Kuala Tanjung

Abstract

This study aimed to evaluete the effect of extender coconut water and NaCl on sperm motility, viability, and fertility of riverine bagrid catfish (Hemibagrus nemurus) storage. This experiment used Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely Treatment P0: 0.1 ml sperm plus coconut water 0% + NaCl 100%, P1: 0.1 ml sperm plus coconut water 40 % + NaCl 60%, P2: 0.1 ml sperm plus coconut water 50% + NaCl 50%, P3 0.1 ml sperm plus coconut water 60 % + NaCl 40%, and P4 0.1 ml sperm plus coconut water 70 % + NaCl 70%. The results showed that the addition of coconut water and NaCl on sperm storage significantly affect sperm quality of catfish and during 96 hours of storage. The result showed that the best quality sperm of catfish treated by P2 was higher than (P<0,05) other treatment. In addition, the optimal storage time was in 48 hours, because it had very good motility and highest viability (63,861%). But after 96 hours in storage, fertility decrease until 21,80%.Keywords: Hemibagrus nemurus, coconut water, spermatozoa

The research of effect of different feed on brood stock to ovulation, incubation and larval survival rate of Ingir-ingir fish (Mystus nigriceps) has been implemented in Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Sciences University of Riau, Pekanbaru from January until March 2016. This study used a complete randomized design with four treatments consisting of feeding the form earthworms (Lumbricus rubbelus), feeding the form Hairy Cockle (Anadara antiquata), and feeding the form million fish (Poecilia reticulata). Each treatment was repeated three times. The results showed that difeerent feed brood stock Ingir-ingir fish (Mystus nigriceps) produces the best on feeding the form million fish (Poecilia reticulata) which produce latency time 6, 47 (hours, minutes), the number of eggs striping result average of 1061 eggs/g broodstock, fertilization rate average of 19,38%, hatching rate average of 53,96% and larval survival rate average of 66,85%.Keywords: Mystus nigriceps, feed, ovulation, incubation, survival rate
