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 study was to examine the effect of fish silages, bakasang as an immunostimulant in eel (Anguilla marmorata) feed against Aeromonas hydrophila infection. Three hundred elvers with the size of + 10 cm taken from Freshwater Aquaculture Institute (BBAT) Tatelu. The elvers were placed into 4 glass aquarium, each equipped with aerator and 1 for stock. Prior to the study, the eels were acclimatized for two weeks in order to adapt to new environmental condition. Two sets of researches were done: feeding the eels with additional bakasang with different doses for 6 weeks, which then further were challenged with Aeromonas hydrophila by immersion method. This study used a completely randomized design (CRD) with 4 treatments A (0 mL /kg diet), B (50 mL/kg diet), C (100 mL/kg diet), D (150 mL/kg diet). The growth data was taken by measuring the weight and length of the eels at the end of the period of feeding treatment while the mortality data of the eels were observed for 10 days after challenge test.  The results of analysis of variance showed that the resistance of the eels in treatment B (50 mL/kg diet), C (100 mL/kg diet) and D (150 mL/kg diet) significantly different compared with treatment A.  However, among the treatments B, C and D, there were no significant differences.  Furthermore, the best eel growth was observed in treatment B with an absolute growth of 1.14 g, followed by treatment of D with an absolute growth of 1.04 g. In treatment A the absolute growth was only 0.82 g while treatment C was 0. 88 g.  This suggests that the addition of bakasang in eels feed can promote the growth of eels as well as resistance against pathogen infection, thus served as immunostimulant.

Abstract

This study was aimed to find out the growth rate of Nile Tilapia (Oreochromis niloticus) cultured with biofloc technology, and to understand the dynamic of several water quality parameters during culture period. This experiment was conducted in the Laboratory of Aquaculture Technology, FPIK, UNSRAT.  Several substances were added to stimulate the development of biofloc, which were: 0,3 mL of EM-4 containing probiotic-bacteria Lactobacillus casei dan Saccharomyces cerevisiae.; 15 mL of mollases;  0,5 g of  yeast commonly used to ferment soybean ; 12 g of dolomite.    60 seeds of  nile tilapia,  with an individual weight of 6 g, were stocked in each container.   Fish were fed at a dose of 3% of the total biomass/day at the first week, and the dose was decreased  down to 1% of the total biomass per day afterwards.  Fish were weighed at day-1, day-15 and day-30.   The change of water color and the density of the floc was consistently evaluated using imhoff-cone. The initial weight of the tested individual fish were 6,00 g. After 15 days, the weight was increased to 7,37g, and at the end of the experiment the individual fish weighed 11,47 g. Hence, the absolut growth of the tested fish was 5,47g,  the specific growth rate was 91% and the daily growth rate was 2,11%.    The density of flok reached 9,5 mL/L at the beginning of the second week, which was categorized as very high density.   The density of floc then was decreased to 4 mL/L.   The density of the floc was maintained around 5 mL/L during the experiment. The temperature of the medium was at the range of 26-300C.  The level of ammonia was 0,03mg/L and  the level of  nitrite fluctuated between 0,15-3mg/L, which is normal and safe for biofloc system.  The level of nitrate was 4-55 mg/L, which was quite high for biofloc system but not harmful for fish.   Keywords:  Biofloc, Nile-Tilapia, growth, floc-density

Abstract

A research had been conducted to identify and analyze the prevalence of ectoparasites on Nile tilapia (Oreochromis niloticus) cultured in Kampung Hiung, Manganitu District of Sangihe Island Regency during May 2016. Identification was conducted at The Laboratory of Fisheries and Maritime, Polytechnic of Negeri Nusa Utara.  The research found five parasite species infecting nile tilapia including Dactylogyrus sp, Oodinum sp, Lerneae sp, Gyrodactylus sp and Trichodina sp. The highest prevalence value was Dactylogyrus sp (86.67%), followed by Oodinium sp (33,33 %), Lerneae sp (13,33%), Gyrodactylus sp (6.67%) and Trichodina sp (6.67%) Keywords:  parasite, identification, prevalence, Oreochromis niloticus

Abstract

This study was conducted to determine the effect of yeast as a counterweight of fibrous raw material in Tilapia  feed formulations on growth and feed efficiency value. The research results found that the biggest absolute growth of Tilapia fry occurred in treatment A: 5% yeast (9,2 g),  followed by  C: 15% yeast (8,6 g), D: 20% yeast (7,14 g), and B: 10% yeast (5,03 g). The highest feed efficiency value occurred in treatment A (23,75%), followed by C (22,45%), D (18,69%) and B (13,96%). The parameter of water quality measured during experiment included temperature 26-28o C and pH  7. The range value of water quality in each treatment was considered to be proper for the living condition of fish fry. Keywords: yeast, Oreochromis niloticus, growth, feed efficiency

Abstract

This research aimed to gather data and information as well as to evaluate the waters condition and water quality suitable for ornamental coral aquaculture, so the characteristic of Arakan waters for ornamental coral aquaculture could be examined.  The research applied Explorative Descriptive method with Purposive Sampling.  Research stations were established at 20 points representing the overall ecosystem of Arakan waters.  Data collected  consisted of physical conditions (bottom substrate, flow rate, turbidity, water depth, salinity, temperature, TSS) and  chemical conditions (pH, DO, nitrate, phosphate). Data were analyzed using Matching Method by matching the data obtained from sea water standard quality table for marine biota in accordance to Kep.Men. LH No. 51/2004 and data from Hutabarat and Evans (1984).  Based on physical and chemical conditions, Arakan waters was suitable for ornamental coral aquaculture or categorized as suitable. However, water temperature at the time of measurement was not proper,  thus monitoring of this parameter for longer period was required. Keywords: Arakan Village, ornamental coral, water quality, waters condition,  matching                      method
