Influence Durian Leaves (Durio zibethinus) Infusion as Natural Anesthesia of Striped Catfish Juvenile (Pangasius sp.)

The use of anesthesia in the process of living fish transportation is an effort in keeping the physiology of fish alive and healthy to the destination. Durian leaves are one of the natural ingredients that can be used as fish anesthesia. The purpose of this research is to know the effective concentration of infusum durian leaves as anesthetic seeds of patin fish based on inductive time, sedative time and survival rate. Experimental studies use complete randomized designs, four treatments and threefold. The treatment of infusum concentrations of durian leaves 10%, 20%, 30%, and 40%. The time when fish begins to faint when inserted into the anesthesia solution is recorded as inductive time, whereas the time the fish began to recover back or knowingly recorded as a sedative time. The survival calculation is done on the number of fish surviving post-anesthesia with maintenance for 3 days. The results of this study showed that the effective concentration gained was 10%, with the inductive time (71.67 minutes) distinct from the apparent 20% concentration, but no apparent difference with the concentration of 30% and 40%. Meanwhile, the sedative time (0.25 minutes) differs from the concentration of 40%, but does not differ with concentrations of 20% and 30%. The survival rate of the fish seed Patin at a concentration of 10% showed real distinct results and reached 100%. Infusum concentration of durian leaves by 10% is an effective concentration in the anesthetic process of patin fish seeds

Phytoplankton diversity and abundance in biofloc cultivation of African catfish with different stock density

High fish stock density causes a decrease in water quality due to increased organic waste in water media and this can be overcame using biofloc technology. The bacterial consortium in the biofloc system breaks the organic compound into nutrients for phytoplankton growth. This research aims to determine phytoplankton abundance in biofloc ponds with different catfish stocking densities. Furthermore, a completely randomized design (CRD) was used, with four treatments and three replications. The treatments involved 1,000, 1,500, 2,000, and 2,500 catfish per m3, respectively, with a weight of ± 1-3 grams. Also, the fish was fed 3% of its body weight and reared for 40 days in a tarpaulin pond, with a water volume of ± 1,974 L. The AMOVA test was used to analyze the data and 10 phytoplankton genera were observed. However, the phytoplankton abundances showed no statistical significance among the treatments. The results showed that the first treatment had the most abundant phytoplankton, with an average number of 13,394 cell/L.Keywords:AbundanceBioflocCatfishDensityPhytoplankto

Efektivitas Infusum Daun Durian (Durio zibethinus) Sebagai Anestesi Alami Ikan Lele (Clarias gariepinus)

Artificial or natural anesthetic ingredients are needed in the transportation of live fish, because fish must be physiologically alive and healthy to their destination. Durian leaf is one of the natural ingredients that can be used as anesthetics in transport because it contains secondary metabolites such as saponins, tannins and flavonoids. The purpose of this study was to determine the effective concentration of durian leaf infusion as catfish anesthesia during transportation on induction and sedative time, blood glucose profile and survival rate. Fish with an average weight of  185,62 ± 9,06 g in 3 L of water with different concentrations of durian leaf anesthetics are used to determine the status of fish fainting. A complete randomized design (CRD) with four treatments (5%, 15%, 25%, and 35% durian leaf infusion concentrations) and three replications were applied in this study. The results of this study indicated that the best concentration obtained was 35%, with an inductive time of 9 min.19 sec. and a sedative time of 1 min.42 sec. The survival rate of catfish in the best treatment was 88.89%, with a blood glucose level of 63.23 mg/dL.Bahan anestesi buatan atau alami sangat dibutuhkan dalam transportasi ikan hidup, karena ikan secara fisiologi harus tetap hidup dan sehat sampai tempat tujuan.

Growth performance of African catfish Clarias gariepinus cultured in biofloc system at high stocking density

ABSTRACT This study was aimed to analyze the growth performance of African catfish Clarias gariepinus cultured in the biofloc system at high stocking density. African catfish with an average weight of 1.85±0.09 g were cultured in four units of tarpaulin tank at a diameter of 1.72 m and a height of 1.05 m with a volume of ±2,000 L at the different density of 1,000 fish/m3; 1,500 fish/m3; 2,000 fish/m3; 2,500 fish/m3. During rearing period, fish were given the artificial feed with protein contents of 28.75% with the frequency of twice a day, as much as 3% of the body weight. The results showed that different treatment of high stocking density in the biofloc system had a significant effect on the absolute growth rate, lipid retention and energy retention (P&lt;0.05) but not significant effect on daily growth rate. The results showed that the highest lipid retention and energy retention were found in the group of fish treated at a stocking density of 2,500 fish/m3 but declining protein retention and growth in fish occurred. The highest absolute growth rate and daily growth rate were shown by treatment with a stocking density of 1,500 fish/m3. Keywords: growth, stocking density, biofloc   ABSTRAK Penelitian ini bertujuan untuk menganalisis performa pertumbuhan ikan lele dumbo Clarias gariepinus yang dipelihara pada sistem bioflok dengan padat penebaran tinggi.  Ikan uji memiliki berat rata-rata 1,85±0,09 g yang dipelihara pada kolam terpolin berdiameter 1,72 m dan tinggi 1,05 m dengan volume air ±2.000 L sebanyak empat unit dengan kepadatan yang berbeda yaitu 1.000 ekor/m3, 1.500 ekor/m3, 2.000 ekor/m3, 2.500 ekor/m3. Selama 40 hari masa pemeliharaan, ikan diberi pakan buatan berkadar protein 28,75% dengan frekwensi dua kali sehari, sebanyak 3% dari berat tubuh. Hasil penelitian menunjukkan bahwa perlakuan perbedaan padat penebaran tinggi pada sistem bioflok memberikan pengaruh yang nyata terhadap pertumbuhan mutlak, retensi lemak dan retensi energi (P&lt;0,05) namun tidak memberikan pengaruh nyata terhadap laju pertmbuhan harian. Hasil penelitian menunjukkan bahwa semakin tinggi padat penebaran terjadinya peningkatan retensi lemak dan retensi energi yaitu pada perlakuan padat penebaran 2.500 ekor/m3 tetapi terjadi penurunan nilai retensi protein dan pertumbuhan pada ikan. Nilai pertumbuhan mutlak tertinggi ditunjukkan oleh perlakuan dengan padat penebaran 1.500 ekor/m3.    Kata kunci: pertumbuhan, padat tebar, bioflok</p
