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

Study was conducted in January-February 2015, at mandiangin Freshwater Aquaculture Centres,kalimantan selatan province. This study aims to determine the growth of the seed gabus fish (Chana striata)and survival rate of the seed gabus fish(Chana striata) as well as to determine the efficiency of feed consumed of the seed gabus ffish (Chana striata), which are given artificial feed with different protein content. The research method used an experimental with 3 treatments and 3 replications of feeding 2 times a day with different protein content is 30 % , 35 % and 40 %. Test materials used 180 gabus fish (Chana striata) a container of 9 aquarium with stocking density 1 head / liter. The results showed that the artificial feeding with a protein content of 40% better compared to the feeding with a protein content of 30% and 35 %,that is a higher growth of weight gain (2,896 g), daily growth rate (9,03%), survival rate (80%)and feed efficiency 89.65 %.Keyword :Gabus fiish (Chana striata), Fedding made with diferen protein content, and growth.

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.

Abstract

This research was intended to determine the effect of different packaging on the catfish proteinconcentrate sagoo noodle fortified with microalgae (Chlorella sp.) and catfish oil (Pangasiushypopthalmus) during room temperature storage. The method used in this study wasexperimental andcomposedas non factorial completely random design. Those were threetreatment, namely: A1 HDPE (high density polyethylene) packaging, A2 alumunium foilpackaging, and A3 is alumunium foil and HDPE combination packaging. Those were grouped for3 storage time, namely: B1 (day 0), B2 (days 15), dan B3 (days 30). The parameters used to assessthe quality of sagoo noodle were organoleptic value (consistence, flavor, aroma, and texture),water content, fat, peroxide value, and the total colony bacteria. The product packed by usingthe alumunium foil (A2) was showing the best quality, with characteristic of consistencewaswhite, catchy, whole and tidy. The flavor was specific sagoo noodle, the aroma was also specificsagoo noodle, and the texture was elastic, compact, whole and flexible.Keyword : Package, Sagoo noodle, Microalgae (Chlorella sp), Fish oil

Abstract

Aek Sidempula River, a small river that has high quality water and it is inhabitedby aquatic organisms such as crabs. Scientific information on crabs living in thatarea, however, is almost none. To understand the crabs present in that river, astudy has been conducted from November 2015 to January 2016. The crabs wascaptured using traditional line fishing. Morphometrical and meristicalcharacteristics on the crabs captured were described based on Ng dan Tan (1998)and Ng and Takeda (1992). The crabs sampled were only 40 crabs, and they werebelonged to a single species namely Malayopotamon tobaense (Potamidae). Thisspecies is medium sized crab, 16 – 49 mm carapace width, with dark purplecarapace. This species is characterized by the presence of first gonopod that hasupward turned tip. Male has bigger chelae and narrower abdomen than that of thefemale.Keywords: Crabs, Potamidae, Malayopotamon tobaense, Aek SidempulaRiver, Pearung Silali, North Sumatera.
