Abstract

The aim of this study was to evaluate the nutritional content of fermented tarum leaf meal and its nutrient digestibility on hoven’s carp juvenile. This study consisted of two steps namely fermentation and determination of nutrient digesti-bility of tarum leaf meal. Sheep’s rumen fluids used as fermentator of tarum leaf, fermentation was performed for 24 hours with several levels at 0, 200, 400 and 600 mL kg-1, then dried and analyzed for proximate. Digestibility trial was carried out for fermented and non-fermented tarum leaf meal. Digestibility trial was conducted by adding Cr2O3 as the indicator and faecal collection through siphoning. Hoven’s carp (2,31± 0,02 g) were cultured for 30 days using 60 cm x 50 cm x 40 cm aquarium with a density of 25 fishes aquarium-1. Fish were fed three times daily ad satiation. Feces were collected one hour after feeding, dried and analyzed. Fermentation test showed that the nutrient content of fer-mented tarum leaf meal using 600 mL kg-1 dose was better and significantly than other doses in crude fiber and nitrogen free extract were 9,32±0,53and 49,23±1,11. The decrease of crude fiber were 36%. Digestibility test showed that the raw material digestibility, protein digestibility, fat digestibility and energy digestibility in use tarum meal was better and significantly different than non-fermented tarum leaf meal. The results showed that fermented tarum leaf meal at 600 mL kg-1 increase quality of nutrients and digestibility of hoven’s carp seed. Abstrak Penelitian ini bertujuan untuk mengevaluasi kandungan nutrisi dari fermentasi tepung daun tarum dan kecernaannya terhadap benih ikan jelawat. Penelitian terdiri atas dua tahap yaitu fermentasi dan uji kecernaan bahan dari tepung daun tarum. Fermentasi tepung daun tarum menggunakan cairan rumen domba sebagai fermentator. Fermentasi dilakukan selama 24 jam dengan dosis 0 (kontrol), 200, 400, dan 600 mL kg-1, kemudian dikeringkan dan dianalisis proksimat. Uji kecernaan menggunakan tepung daun tarum yang difermentasi dan tanpa fermentasi. Uji kecernaan bahan dilakukan dengan menambahkan Cr2O3 pada pakan sebagai indikator dengan metode penyifonan feses. Ikan jelawat (2,31± 0,02 g) dipelihara dalam wadah akuarium ukuran 60 cm x 50 cm x 40 cm dengan kepadatan 25 ekor akuarium-1 selama 30 hari. Ikan diberi pakan tiga kali sehari secara satiasi. Feses diambil satu jam setelah pemberian pakan, dikeringkan dan dianalisis kimia. Uji fermentasi menunjukkan bahwa kandungan nutrien tepung daun tarum yang difermentasi menggu-nakan dosis 600 mL kg-1 lebih baik dan berbeda nyata dibandingkan dosis lainnya pada kandungan serat kasar dan ba-han ekstrak tanpa nitrogen yaitu 9,32±0,53dan 49,23±1,11. Penurunan serat kasar terjadi sebanyak 36%. Uji kecernaan menunjukkan bahwa kecernaan bahan, kecernaan protein, kecernaan lemak, dan kecernaan energi pada penggunaan tepung daun tarum yang difermentasi lebih baik dan berbeda nyata dibandingkan dengan tepung daun tarum tanpa fer-mentasi. Hasil tersebut menunjukkan bahwa fermentasi tepung daun tarum dengan dosis 600 mL kg-1 meningkatkan kualitas nutrisi bahan dan kecernaan terhadap benih ikan jelawat.

Abstract

. This study aims to determine the optimum density and to analyze the effectiveness of zeolite and activated carbon additives in the transportation of jelawat fish seed 2-inch for 12 hours. This research was conducted in March-May 2023. Transportation was carried out for 12 hours with the mode of transportation being a 4-wheeled minibus with travel routes starting from Jambi City to West Tanjung Jabung Regency. The experimental design used was a Completely Randomized Design (CRD) with 4 (four) treatments and 3 (three) replications, the treatments given were densities including: treatment A density of 100 individuals/container, treatment B density of 200 individuals/container, treatment C density 300 individuals/container and treatment D at a density of 400 individuals/container. In each container, 20 g and 10 g of zeolite and activated carbon were added. After being transported, the fish were maintained for 14 days. The results showed that during the transportation there were no fish deaths in all treatments so that the survival rate in all treatments was 100%. The average blood glucose level before transportation ranged from 56.3 – 57.3 mg/dL. The survival rate of post-transported barnet fish fry on day 0 to day 7 was 100%, while on day 14 the survival rate ranged from 90.1% -92.3%. Absolute length growth ranged from 1.30 cm/head – 1.38 cm/head. Absolute weight growth ranged from 0.30 gram/head-0.32 gram/head. Blood glucose levels at the start of maintenance ranged from 62.0-87.0 mg/dL. On the 14th day it ranged from 38.3 mg/dL-48.7 mg/dL. The water quality during the transportation and rearing process is still in the optimal range for barley fingerlings

Abstract

Cinnamon leaves contain active compounds such as polyphenols and flavonoids which have antioxidant properties and play a role in lipid metabolism processes. This active substance is known to reduce liver fat levels and has the potential to increase the immune response in catfish. This research aims to determine the effect of adding cinnamon leaf extract to feed on liver fat levels and the health of catfish. Cinnamon leaf extract was added to the feed at five different doses, namely 0 g/kg (control), 0.5 g/kg, 1 g/kg, 2 g/kg, and 4 g/kg feed. The results of the study showed that the addition of cinnamon leaf extract to the feed reduced the fat content in the liver of catfish as seen from the decrease in fat degeneration in the liver of catfish compared to the control. Total erythrocytes, hemoglobin levels and hematocrit levels of fish treated with the addition of cinnamon leaf extract to the feed were lower and significantly different (P<0.05) compared to controls, but total leukocytes were not significantly different between treatment and control.

Abstract

Feed in aquaculture production is the largest production factor. Dependence on imported feed raw materials is the cause of high feed prices in fish farmers. One approach that can be done as a solution is the utilization of local raw materials, namely I. zollingeriana leaf flour fermented with sheep rumen fluid. This study aims to evaluate the use of fermented I. zollingeriana leaf meal (TDI) in feed as a substitute for soybean meal on the growth performance of catfish (L. hoevenii) fry. This study was conducted from December 2016 to June 2017. The research was conducted at the Wet Laboratory and Nutrition Laboratory of the Center for Freshwater Aquaculture Research and Fisheries Extension (BRBATPP), Bogor. This study consisted of four treatments and three replicates, namely the use of fermented amount of I. zollingeriana leaf meal (TDI) in feed as much as 0%, 10%, 20% and 30% made in isoprotein. The test fish used were jelawat fish that weighed 0.93 ± 0.02 g with a stocking density of 25 fish per aquarium. The container used was a 60x40x40 cm3 aquarium filled with water and equipped with 24-hour aeration. The results showed that the use of fermented I. zollingeriana leaf meal in feed up to 30% was significantly different from the control (0%) in several parameters including protein efficiency ratio, protein retention, fat retention, final weight, specific growth rate and feed efficiency, but not significantly different in the amount of feed consumption, hepatosomatic index and survival rate. The use of fermented I. zollingeriana leaf meal up to 20% showed results that were not significantly different from the control. Up to 20% fermented I. zollingeriana leaf meal can be used in tilapia (L. hoevenii) feed

Abstract

The nursing phase of Jelawat Fish (Leptobarbus hoevenii Blkr) is a crucial stage in aquaculture, where preparing healthy and robust fry poses a significant challenge. The availability of fry for grow-out activities remains low, consequently limiting the production of Jelawat Fish. This study aims to determine the optimal stocking density under an intensive culture system by evaluating production performance and physiological conditions in a recirculating system for 40 days. The study was conducted using a Completely Randomized Design with four treatments and three replications for each treatment: A (5 individuals/L), B (10 individuals/L), C (15 individuals/L), and D (20 individuals/L). The results showed that high stocking densities significantly affected absolute weight gain (AWG), absolute length gain (ALG), feed conversion ratio (FCR), weight variation coefficient (WVC), and length variation coefficient (LVC). The weight gain increased from 0.50±0.09 g/individual to between 1.51±0.03 g/individual and 1.86±0.05 g/individual, while the initial length of 4.10±0.29 cm/individual increased to a final range of 5.36±0.05 to 5.72±0.06 cm/individual. The lowest FCR was observed at a stocking density of 10 individuals/L (1.33), whereas the highest FCR was found at 20 individuals/L (1.52). Water quality parameters remained within the optimal range for Jelawat Fish culture throughout the study. Therefore, a stocking density of 10 individuals/L is recommended as the best option to achieve optimal growth while maintaining stable physiological conditions in fish.
