Abstract

This research was held in June-November 2015 in Parasites and Fish Diseases Laboratory, Faculty of Fisheries and Marine Science, University of Riau Pekanbaru. This research aimed to determine survival rate of Pangasius hypopthalmus that are immersed in curcumin (Curcuma domestica V) and infected by Aeromonas hydrophila. This research used five treatment such as; Kn (negative control): were not immersed of curcumin and were not infected A. hydrophila, Kp (positive control): were not immersed of curcumin and infected by A. hydrophila), P1: immersed with curcumin 0,5g/L, P2 immersed with curcumin 0,7g/L and P3: immersed with curcumin 0,9 g/L. The fish were immersed with curcumin for two minutes each once a week and they were reared for 28 days. The result showed P1 ( immersion with curcumin solution in a dose of 0,5 g/L) were the best treatment with survival rate of 93,33% and total of leucocytes 16,1167x104 cell/mm3. It was concluded that curcumin can be used for prevention of A. hydrophilla and increase the survival rate of Pangasius hypopthalmus.Key words: Pangasius hypophthalmus, Curcumin, Aeromonas hydrophila

Abstract

A research was conducted from January-February 2016 at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Science, University of Riau Pekanbaru. The purpose of the research was to evaluate the duration of laser puncture exposure on gonad maturation of angle fish (Pterophyllum scallare). Completely randomized design was used to analyze the gonad maturation at the different duration of laser puncture exposure (0, 15, 20, and 25) seconds. The shooting was done twice a week for 4 weeks. The brood fish were reared in 54 L aquarium tank (60x30x35 cm) and fed on 38% protein pellet plus 57% protein tubifex worm.The results of research showed that there was an effect of laser puncture exposure duration, on gonad maturation of angle fish (Pterophyllum scallare). The best duration of laser puncture to stimulate gonad maturation was 20 second. At the duration the maturation was reached in 35 days with gonado somatic indeks 6,3 %, fecundity 908 eggs, and eggs diameter 1.5 mm. The temperature range from 26-27 oC, pH 5-6, and DO 5,7-6,8 ppm.Key words : laser puncture, gonad maturation, angle fish

Abstract

The research was conducted from 20 April 2015-14 July 2015. Thepurpose of this research was know the amount of water hyacinth in the diets ongrowth, feed afficiency and protein retention of river carp (Leptobarbus hoevenii).Five isonitrogenus (30% crude protein) experimental diets was formulated tocontain 0, 10, 20, 30 and 40% water hyacinth and 100, 90, 80, 70 and 60% soybenmeal (P0, P1, P2, P3 and P4, respectively. Completely randomized design (CRD)was used in this experiment. The results showed that a diet containing 40% waterhyacinth and 60% soyben meal (P4) support a good specific growth rate(1.0%/day) feed efficiency rate (22.23%) forage digestibility (54.95%) and proteinretention (24.54%). Survival rate of fish was high (98%). In this concluded that upto 60% soyben meal can be substituted with water hyacinth in the diets for rivercarp.Key word: Diet, growth, Leptobarbus hoevenii, substitution, water hyacinth

Abstract

A feeding experiment was conducted to determine the optimal dose of growth and survival rate for larval perch (Lates calcarifer). Larval initial average weight 0,022 g, initial average body length 7,38 mm and old 15 days. Completely randomized design with five treachments and three replications were use : A (naupli artemia), B (naupli artemia + squalene 0,3 g/L), C (naupli artemia + squalene 0,6 g/L), D (naupli artemia + squalene 0,9 g/L), E (naupli artemia + squalene 1,2 g/L). The results showed that the growth in survival rate, growth of body weight (AW), and growth of body length(AL). Based on the evaluation of the some parameters ; SR (80,6%), AW(0,813 g) AL (3,21 cm)and SGR (16,1 % day). It can be concluded that treatment D (naupli + squalene 0,9 g/L) is optimal for growth and survival rate for larval perch (Lates calcarifer).Key words : Lates calcarifer, different dose, enriched by squalene

Abstract

Three candidates of probiotic bacteria isolated from kakap putih (Lates calcarifer) had been examined for their antagonism against Vibrio alginolyticus. However, the ability to suppress the pathogen in co-culture system has not been tested. This research aimed to test the ability of probiotic candidates to suppress the growth of V. alginolyticus in co-culture trial. Three probiotics candidates (KP1, KP2, and KP3) were used in this experiment method. Four treatments consisted of P1 (broth culture of KP1 + V. alginolyticus), P2 (KP2 + V. alginolyticus ), P3 (KP3 + V. alginolyticus), P4 (V. alginolyticus) as control were prepared in triplicate. Total counts of each probiotic candidate and V. alginolyticus was calculated after 48 hours culture incubation. KP1 isolate showed highest ability suppress the growth of V. alginolyticus, followed by KP3 and KP2 isolates.Keywords: Probiotics, Kakap Putih, Growth, V. alginolyticus, Co-culture

Abstract

This research was conducted in September 2015 in the coastal waters of Belakang Padang, Batam Riau Archipelago Province to analyze the concentration of oil in the water and sediment, the difference and the relationship between oil concentration in the water and in the sediment. Water samples were taken by using sample bottles and sediment samples were taken by using Ekman grab from 15 sampling sites, and then they were analyzed in the Marine Chemistry Laboratory University of Riau. The highest concentration in the water was found in Station 2 (0.1823 ppm) and the lowest in Station 3 (0,1328ppm). The highest oil concentration in the sediment was in Station 2 (286 ppm) and the lowest in Station 3 (130 ppm). The concentration of oil in the sediment were higher than in water. Oil concentration in the water and in sediment has weak relationship and negatively correlated. Characteristics of the sediment in the sampling sites was dominated by sand fraction.   Key words :Oil, Sediment, Water, Batam

Abstract

This research was conducted in December 2015 in the Belimbing Bay coastal area of the PesisirSelatan Regency, West Sumatra Province. The purpose of study was to determine the distribution andabundance of bivalves in the intertidal zone. Bivalves samples were taken by using Quadrant TransectSampling Method, in which at each station had one line transect, divided into three plots with a size of3x3 m2, respectively. The study found the abundance of the bivalves at station I (middle zone) washigher (0.15 ind/m2) than in the lower zone (0.07 ind/m2). In station II the lower zone was 0.07 ind/m2lower while the middle zone was 0.16 ind/m2. In station III the highest abundance was in the middlezone (0.15 ind/m2) and the lowest abundance was in the lower zone (0.08 ind/m2). The highest organicmatter content in the station I was 6.97% and the lowest was in the upper zone (4.85%). The lowestorganic matter at station II was lower zone (5.48%), followed by the upper zone (5.74%), and thehighest is in the middle zone (5.96%). At station III, the highest organic matter was 5.54% andfollowed by the lower zone 5.22%, the lowest contained is in the upper zone (5.12%).Keywords: Bivalves, Distribution, Abundance, Belimbing Bay, West Sumatera.
