Abstract

Anesthetic method is an important component to support the activities of transporting live fish from one place to another for a long period of time. Cost efficiency and effectiveness of anesthetic ingredients that not cause residues in fish are factors to beconsidered as an anesthetic. Aim of this research is to study the effect of subletal concentration of amethyst leaf extract on the hematological conditions of tilapia fry after transporting on wet transportation systems. The research procedure was through the amethyst leaf extract toxicity test series (LC50-96 hours) to determine its sublethal concentration by 20% (0,297 ml/l), 30% (0,445 ml/l) and 40% (0,594 ml/l) of the LC50 value. The measured parameters are clinical symptoms, period of fainting and conscious recovery, hematological analysis, survival rate, and water quality. The results showed the concentration of amethyst leaf extract had an effect (P<0,05) on the period of fainting and the hematological component after transportation simulation. Results of water quality measurement showed the parameters of pH at 6 and ammonia 0,04 mg/l are not at the optimum value when fish transportation occur. The recommended concentration of amethyst leaf extract for use as an anesthetic agent is 0,445 ml/l

Abstract

The purpose of this study was to identify and morphologically characterize the hemocyte cell types of freshwater crayfish, Cherax cainii. In addition to morphological observations using a light microscope (LM) and electron transmission microscope (TEM), a flow cytometer (FCM) is also used. Three main types of haemocyte of C. cainii were identified by LM, TEM, and FCM. Determination of haemocyte by LM based on the number, size of cytoplasmic granules and the ratio of N:C. These cells are Hyaline (HC), Small Granule (SGC), and Large Granule (LGC) cells. Three types of haemocyte were also observed by TEM based on cell and nucleus size, granule diameter, number of cytoplasmic granules per cell and N:C. Haemocyte population was successfully detected with FCM based on forward scatter (FSC) signals, versus side scattering signals/side scatter (SSC), with plot data via scatter parameter gating. Three cluster formations were observed, which were temporarily classified as SGC, LGC, and HC regions. Morphometric analysis was performed with TEM on C. cainii haemocyte to measure various cellular features. Some morphological features vary between types of haemocyte and are also affected by temperature. Total hemocyte count (THC) and differential hemocyte count (DHC) are calculated using FCM. THC increases with higher temperatures, from 1,9 x 106 /ml at 20 °C to 4.9 x 106 /ml at 30 °C.  The most abundant hemocyte at all temperatures is HC, followed by SGC and LGC.

Abstract

Oodev hormone application has been applied to stimulate gonadal maturity so that fish fry could be available outside the spawning season. This research aimed to study the effect of Oodev hormone on the gonadal maturity of asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840). This research method used a completely randomized design (CRD) with 4 doses treatments, i.e 0, 0,25, 0,50, 1,00 ml/kg. A total of 8 fish were used as replications for each treatment. The parameters measured were the gonado somatic index (GSI) and egg diameter. The results showed that the effect of Oodev hormone on GSI and egg diameter was significantly different (P<0.05). A higher Oodev hormone dose caused an increase of GSI and egg diameter size. The recommended Oodev dose for application is 1 ml/kg.

Abstract

Vibriosis is a disease that often attack shrimp culture, some of the most dangerous types of Vibrio bacteria are V. harveyi. The use of natural materials is an alternative that can be applied to prevent bacterial disease. One of the mangrove species that has an antibacterial compound is A. alba. A. alba has alkaloid, saponins, and flavonoids compounds that can inhibit the function of cytoplasmic membranes and energy metabolism in bacteria. This study was conducted to determine the effectiveness of A. alba leaf extract A. alba in inhibiting V. harveyi disease in vaname shrimp (Litopenaeus vannamei). This research was conducted in several stages, namely extraction of mangrove leaves, both in vivo and in vitro. The highest SR, RPS and MTD values were obtamed at a concentration of 250 mg/l with each value of 80 %, 60 %, 75th respectively hour. Mangrove leaf extract A. alba was able to prevent diseases caused by the bacteria V. harveyi, with the best results at an extract concentration of 250 mg/l where the concentration can significantly higher SR, RPS, and MTD compared to other treatments.

Abstract

Leucaena leaves is a potential ingredient for raw material feed of catfish. The aim of this study is to evaluate the effects of dietary fermented leucaena leaf on digestibility and hematological parameters of catfish. Four treatments and 3 replicates, namely: A (reference feed 70% + leucaena leaves meal 30%), B (reference feed 70%+fermented leucaena leaves meal with A. niger 30%), C (reference feed 70%+fermented leucaena leaves meal with R. oligosporus 30%), and feed D (reference feed 70%+fermented leucaena leaves meal with S. cerevisiae 30%) were used in this study. The juvenile catfish (initial weight was 5,45±0,16 g) are randomly distributed into eighteen tanks with 40 fish per aquarium. Each diet is randomly assigned to the triplicate aquarium and fed to fish three times a day up to satiation for 4 weeks. The results showed that fermented leucaena leaves treatments were significantly higher (P<0.05) than that control in final weight and feed conversion rasio. Nutrients digestibility and final weight were significantly highest (P<0.05) in fermented leucaena leaves with A. niger compared to the other treatment. The value of protein digestibility was significantly highest (P<0.05) in fermented leucaena leaves with A. niger (76,04%), followed by fermented leucaena leaves S. cerevisiae with (69,71%), fermented leucaena leaves meal with R. oligosporus (68,24%), and control (65,18). Leucaena leaves had no effect on physiological processes in catfish, as shown by hematological parameter values that were within the normal range.

Abstract

Permasalahan pembesaran lele masamo (Clarias sp.) yang terjadi antara lain yaitu kompetisi untuk mempertahankan ruang gerak, mempertahankan hidup dan  konversi pakan menjadi daging kurang optimal yang  mengakibatkan penurunan dalam pertumbuhan dan penurunan  produksi. Penelitian bertujuan mengetahui efektivitas dasar kolam buatan pada pembesaran lele masamo menggunakan penambahan probiotik dan vitamin C terhadap biomassa akhir, kelangsungan hidup, panjang dan bobot ikan. Penelitian dilakukan menggunakan rancangan acak lengkap (RAL) yang terdiri 3 perlakuan  diantaranya adalah perlakuan pemeliharaan lele masamo tanpa menggunakan dasar kolam buatan, tanpa probiotik dan tanpa penambahan vitamin C   pada pakan (TDPC); pemeliharaan lele masamo tanpa menggunakan dasar kolam buatan, dengan penambahan probiotik pada air kolam dan vitamin C pada pakan (TDKB); pemeliharaan lele masamo dengan menggunakan 2 dasar kolam buatan dan penambahan probiotik pada air kolam dan vitamin C pada  pakan (DVPC). Hasil menunjukkan bahwa perlakuan dasar kolam buatan, penambahan probiotik pada air kolam dan penambahan vitamin C pada pakan (DVPC) pada pembesaran lele masamo super intensif berpengaruh nyata terhadap kelangsungan hidup dengan kelangsungan hidup mencapai 94,67%. Tetapi,  perlakuan dasar kolam buatan, penambahan probiotik pada air kolam dan penambahan vitamin C pada pakan  pada pembesaran lele masamo super intensif tidak  berpengaruh nyata terhadap pertumbuhan,  konversi pakan dan biomassa lele masamo. Penelitian ini juga membuktikan bahwa teknologi dasar kolam buatan efektif untuk meningkatkan produksi sebanyak 10% dari produksi normal. Lebih lanjut, pembesaran lele masamo skala super intensif memerlukan aplikasi probiotik dan vitamin C untuk menjaga imunitas dan kualitas air selama pemeliharaan.
