Abstract

This study Aims to Determine the effect of different variations on survival seed cicada goldfish. The method used in this study is completely randomized design with 3 treatments (A = 3%, B = 5%, and C = 7%) and three replications. From these results Obtained survival rate to 83.0% Obtained treatment A, B Obtained 88.33% and 80.0% Obtained C treatment. Then the results of analysis of variance accept the hypothesis Ho that the percentage variation of different cicada extract (3%, 5% and 7%) did not Affect the survival rate of seedlings goldfish. During the last condition of water quality research support for seed viability parameters goldfish.

Abstract

This study aims to determine the growth of gift tilapia (Oreochromis sp) were maintained in Happa in ponds with artificial feeding. This study uses a Quasi-experimental research, which was conducted in Freshwater Fish Culture Hall Mandiangin for 2 months. Research results indicate the relative weight of the resulting growth is 293.48% and for relatively long growth is 79.41%. Test fish feed conversion value is 1.62 with a degree of efficiency of feed utilization was 61.81%. Results of water quality measurements for temperatures ranging between 28-31oC, the pH of the water ranged between 6.5-7 and brightness between 41-74 cm of water.

Abstract

Objective of this research were to know the tolerance rate of common carp to liquid waste of sasirangan industries, effect of liquid waste of sasirangan industries to common carp mortality , water quality media, and common carp gills under exposures in 96 hours. Method in this research was Static Bioassay.  Tolerance Limit Media (TLM) or Lethal Concentration 50 % (LC50) in 96 hours used to determine of common carp tolerance rate with toxicity test.   Before toxicity test, preliminary test be done for determination of  upper and lower limit concentration. Completely randomize design with 5 treatments and 3 replicates was used in this research.  Application of liquid waste concentration as the treatment was K without liquid waste (0%), A (4,5%), B (5,5%), C (6,5%), and D (7,5%).  The data analyzed by using Analysis of Variance (Anova), and Duncan Multiple Range Test (DMRT).          Result of the research showed that tolerance rate of common carp to liquid waste (LC50-96 hours) was in concentration 4,9%.  Mortality rate was 0%; 33,33% and 76,66% for treatment K, A, and B respectively, but for treatment C and D reaches 100 %.    Anova and DMRT result indicated that liquid waste of sasirangan industries had significant effect (P< 0,05) to mortality rate of common carp.  Liquid waste also affect  water quality media such as temperature, pH, BOD, COD, NH3, Zn, and fenol, all of the parameters increasingly, except DO get decrease.  Based of histological analyze, liquid waste had impact to the gills. The  higher the liquid waste concentration makes the higher the damage rate.

Abstract

The aim of this study was to obtain the best salinity for honey prawn (macro) egg prawn (Macrobrancium rosenbergii). This study used Completely Randomized Design, with three treatments and three replications. The results showed that with the salinity of 6 ‰ resulted in an average hatchability of 86.4%, with the salinity of 8 ‰ resulted in 70.5% hatchability, and at salinity 10 ‰ yielded hatchability of 56, 5%. The result of analysis of variance (ANOVA), hatching power of prawn egg very different between treatment. Water quality such as temperature, DO, and pH, during the study can still be tolerated by giant prawns. The results of this study recommend using a salinity of 6 ‰ to do hatching of prawn eggs.

Abstract

This study aims to determine the growth of tilapia gift fed pellets are mixed with a liquid organic fertilizer Bioton much as 10 cc / kg. Test fish are stocked as many as 20 tail  in nets hapa  measuring 1x1x1 m in the pond at  west Mandiangin village, Karang Intan of Banjar regency South Kalimantan for 42 days. During observations show that the results are quite good. the end result test fish weight of 271.5 g with initial weight of 69 g, weight relative growth of 293.48%, 1.109 feed conversion and feed efficiency rate of 90.196%. Waters conditions during the observation, the temperature range of 260-300C, and a pH range of 6.5-7.5. During maintenance avoid death or mortality of 0%, it shows the condition of maintenance medium used is quite supportive for the growth and survival of tilapia gift.

Abstract

The specific objective of this study was to determine the growth and feed efficiency in tilapia (Oreochromis niloticus) fed artificial diets based kiambang that has been fermented with Rhyzopus oryzae. This research are done in May and November 2014, using a completely randomized design. Treatments are different stocking density is 50 individual  / m2 (A), 75 individual / m2 (B), and 100 individual / m2 (C). The results showed: the highest relative growth rate in treatment C for 898,0g / individual, followed by treatment B for 679,25g / individual and A of 455,83g / individual. Feed efficiency ranged between 89.65% - 90.26%. The survival rate of tilapia during the maintenance period is 100%. Results of water quality analysis showed decent range for the life of tilapia where the temperature ranges from 26 ° C - 28 ° C, the degree of acidity (pH) ranged from 7.10 to 7.27, and dissolved oxygen (DO) ranged from 3.5 to 4.1 mg / l.

Abstract

Aim of this research were isolation of probiotics candidate from digestive tract of Danau Panggang swamp fishes and amylolitic, proteolytic, and lipolyticenzyme activity test. Sample fishes were snake head (Channa striata), climbing perch (Anabas testudineus), and Siamese gouramy (Trichogaster pectoralis) as a refresentatif sample from carnivorous, omnivorous, and herbivorous fish.  Medium containing starch, skim milk and olive oil used as selective media. Result of this research was successfully isolated probiotic candidate whom grow well and had enzyme activity from C. Striata obtained 11 isolate, 12 isolate from A. testudineus and T. pectoralis respectively. Higher amilolytic activity was C3GHDP, I3PDP4 had a higher lipolytic activity,  D4SSDP1 and H3PDP had a higher proteolytic activity.  Among those isolate G1PDPsp had a amilolytic, proteolytic and lipolytic activity.
