Abstract

Undergravel airlift pump is a simple filter system that uses air. The purpose of this study was to analyze the efficiency of using Undergravel Airlift Pump in Aquaculture Oreochromis sp. The approach used is an experimental approach with 2 treatments and 1 control. Analysis of the data used is the analysis of variance (ANOVA). The results showed that the application of undergravel airlift pump had an impact on water quality. The treatment of middle airlift  position is more effective compared to the bottom airlift  and control. The temperature and pH parameters were not significantly different; dissolved oxygen and total dissolved solid were significantly different.

Abstract

The transportation process can lead to stress which increases mortality in fish. Efforts to reduce mortality in the process of fish transportation can be conducted by minimizing the metabolic activities of fish during transportation. One of the natural substances that is used for fish transportation is tuba roots. The aim of this study is to determine the effect of different dosages of tuba root extract on the transport of catfish seeds with a closed transport system for 12 hours. This research was conducted at the Aquaculture Laboratory, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University. The research was conducted in April 2019. This study used a completely randomized design (CRD) method with four different dosage treatments (T) and three replications. The dosages of tuba root extract were: 0 ml.L-1 (T0), 0.05 ml.L-1 (T1), 0.10 ml.L-1 (T2), 0.15 ml.L-1 (T3). The parameters observed were blood glucose levels, water quality, survival of catfish after transportation and maintenance for 7 days. The results showed that T1 (0,05 ml.L-1) was gave the highest survival rate of 91.66±2.88%, with the lowest stress level indicated by blood glucose values 89±30.63. In addition, there was no further effect from the administration of tubal root extracts to protect the life of the fish after transportation and maintenance.Keywords : Tuba root, catfish, transportation

Abstract

Management of snakehead fish resources in swamp waters need to be done to anticipate a decline in stock in the waters. At this time the area where snakehead fish still have an abundant population is in southern sumatera, precisely in the Belida River, Muara Enim Regency. Until now there has been no information regarding the reproductive aspects of snakehead fish, their location and spawning season. The purpose of this study was to obtain information about the reproductive aspect of snakehead fish which includes sex ratio, gonad maturity level. Gonad maturity index and egg fecundity. The research was conducted in September-December 2019. The location was determined based on the natural conditions of the Belida River and human activities. Fish sampels were caught using experimental gill nets with ½ mash net size. Sampling of fish is done every 4 months with a time interval of once a month. The resuls of study in the male and female fish ratio 1,6:1. This ratio consisted of 109 fish (62,3%) and 66 female fish (37,7%). Gonadal maturity indeks  for male snakehead fish ranged from 0,21 to 0,86, while female snakehead fish ranged from 1,18 to 2,30. snakehead fish egg fecundity were 24.786 eggs with a diameter of 2,20 ? 2,51

This study was aimed to examine the level of utilization of artemia frozen and decapsulated artemia feed for growth and survival of vaname shrimp postlarva. The experimental design used a completely randomized design (CRD) with three treatments and three replications. The treatments tested were (A) Frozen Artemia, (B) Decapsulated Artemia, (C) Frozen Artemia + Decapsulated Artemia. Research carried out using 6300 PL2 vaname shrimp. Observed parameters include length growth rate and relative weight, feed utilization efficiency,protein efficiency ratio, survival rate and water quality. Feeding frozen artemia provides the best results with a growth in relative weight 128.06 g, feed utilization efficiency of 0.04%, protein efficiency ratio 48.21%, survival rate with a percentage of 56%, and for the relative length growth rate of artemia frozen + artemia decapsulation has the best results of 17.0%. Keywords : Artemia, tilapia, feed, growth

Abstract

Salah satu cara untuk meningkatkan kualitas benih dari ikan budidaya adalah dengan meningkatkatkan respon imun sehingga kebal terhadap serangan penyakit. Penelitian ini bertujuan untuk meningkatkan respon imun non spesifik dari ikan mas dengan pemberian dosis optimum ekstrak Akar Kuning. Perlakuan yang diberikan adalah perbedaan dosis ekstrak Arcangelisia flava Merr., dimana perbedaan dosis tersebut adalah sebagai berikut : A = dosis 0 gr/kg pakan, B = dosis 2,5 gr/kg pakan, C = dosis 5,0 gr/kg pakan, D = dosis 7,5 gr/kg pakan, dan E =  dosis 10,0 gr/kg pakan.  Parameter utama yang diamati adalah pemeriksaan jumlah Hb, He, total eritrosit, total leukosit, persentase neutrofil, monosit, limfosit, dan tingkat kelangsungan hidup (SR).  Pengambilan darah selama penelitian, dilakukan sebanyak dua kali,yaitu pengambilan darah yang pertama dilakukan pada hari ke-14 setelah diberi ekstrak akar kuning, dan pengambilan darah kedua pada hari ke-30 setelah diberi ekstrak akar kuning dan diinfeksi bakteri A.hydrophila.  Hasil penelitian menunjukkan bahwa penggunaan Arcangelisia  flava Merr. sebagai imunostimulan mempengaruhi jumlah Hb, He, total eritrosit, total leukosit, persentase neutrofil, monosit, limfosit dan tingkat kelangsungan hidup Cyprinus carpio L yang terinfeksi oleh Aeromonas hydropila.

Abstract

The pH of waters is one of external factors that is important for succesfull of hatching percentage of fish eggs. The pH stimulates the chorionase enzyme become more active that can softens the egg chorion. The aim of this study was to determine the optimum pH value for hatching of catfish eggs. This research has been conducted in Fisheries Basic Laboratory, Department of Aquaculture, Department of Fisheries, Agriculture Faculty, Universitas Sriwijaya from August 31st to September 16th, 2019. The research metehod used Completely Randomized Design with five treatments and 3 replications. The treatments are P1 (pH of 5±0.2), P2 (pH of 6±0.2), P3 (pH of 7±0.2), P4 (pH of 8±0.2) dan P5 (pH of 9±0.2). The results showed that different value of water pH gave significant effect on hatching percentage, hatching time and survival rate of catfish larvae but did not significant effect on percentage of abnormal larva. The highest hatching percentage (80.33 %) was in treatment of pH 7 ± 0.2 (P3), the fastest hatching percentage (21.59 hours) was in treatment of pH 8 ± 0.2 (P4), the highest survival rate of catfish larvae (99.44 %)  was in treatment of pH 7 ± 0.2 (P3) and the highest percentage of abnormal larvae (2.22 %) was in treatment pH 5 ± 0.2 (P1). During the research, water quality were in tolerance range for hatching and rearing of eggs and larvae catfish i.e. temperature of 26.2 ? 27.9 oC, dissolved oxygen of 4.7 ? 5.5 mg.l-1, and ammonia of 0.22 ? 0.47 mg.l-1.Keyword : Hatching eggs, catfish, pH value

Abstract

The aim of this study is to inventory various types of ectoparasites found in koi fish that are reared in the nursery phase at the Sukabumi Freshwater Aquaculture Center (BPAT Sukabumi). Briefly, a total of 30 koi fish were taken randomly, then the scales, fins, and gills were examined and stained either with procedures of AgNO3. The type of parasite was identified and analyzed based on the rate of prevalence, also the intensity and dominance. The infesting parasite found were Trichodina sp, Oodinium sp, and Ichthyophthirius multifiliis. Overall, Trichodina sp is the most dominating parasite with a dominance level, prevalence, and intensity of 57,028%, 80%, and 10,833 respectively.

Abstract

The purpose of this research were to measure the increasing of unionized ammonia during start-up period of biofloc system for growing Nile Tilapia and to figure out its effect on histopathological changes. There was only one treatment that designed with three replication, which was 40 liters of water that contained eight fishes of each weighed 22.. The biofloc system was treated with C/N ration 12:1. Total Ammonia Nitrogen, pH and temperature were measured daily as long as 14 days. the tissue of gill, liver and kidney were cut off at the end of the experiment for histopathological examination. The result of the experiment showed that the peak of unionized ammonia concentration achieved 0.34±0.05 mg/l at 10th day. Then, decreased rapidly to 0.003±0.0009 mg/l at 14th day. The gill, liver, and kidney had regressive changes as physiologic sub lethal response of unionized ammonia expose. Keywords : Biofloc, unionized ammonia, Nile Tilapia, histopatholocal
