Abstract

This research was conducted from July to September 2021 for 42 days at the Hall of Brackish Water Fish Seed, Kepulauan Meranti Regency, Riau. This study aims to determine the best dose for addition of probiotics to the maintenance media for the growth rate and survival of seabass. This study used completely randomized design (CRD) of one factor consisting of five levels of treatment and three replications. The treatments applied are (P0) control without probiotics (P1) with a dose of 2.5 mL/m3, (P2) with a dose of 5 mL/m3, (P3) with a dose of 10 mL/m3, and (P4) with a dose of 12.5 mL/m3. Research results show that P4 gives the best results of the water quality such as temperature ranges from 27.67-29˚C; water pH ranges from 6.67-7.37; dissolved oxygen (DO) ranges from 4.9-5.53; and ammonia ranges from 0.00138-0.00513. Absolute weight growth of 11.67 g; absolute length growth of 12.33 cm; specific growth rate of 3.78%; survival of 100%; feed efficiency 104.67%; and food conversion ratio (FCR) of 0.95

Abstract

This research aim to determine the optimal dose of additional herbal supplements in feed toward the growth performance and survival rate of red tilapia (Oreochromis niloticus) by using recirculation system. This research was conducted on November 01-December 10, 2021 at Laboratory of aquaculture technology, Marine and Fisheries Faculty, University of Riau. This research was using experimental method by completely random design (RAL) one factor with three replications. The treatments were: A: 0 mL/kg of feed (control), B: 50 mL/kg of feed, C: 75 mL/kg of feed, and D: 100 mL/kg of feed. The herbal supplements were consisted of turmeric, and ginger with Bacillus sp. and yeast (Rhizopus oligosporus). The results showed that a different doses of additional herbal supplements affecting the growth performance and the survival rate of catfish using recirculation system. In addition, it also affected the absolute weight growth, absolute length growth, feed efficiency and feed conversion ratio.The optimal dose was at 100 mL/kg of feed as it showed significantly different results compared to control. So that while being applied in terms of economy, 100 mL/kg was the most efficient dose, by giving the specific growth rate was 1,55%, survival rate was 98,3%, absolute weight growth was 8,67 g, absolute length was 6,23 cm, feed efficiency was 79,53% and feed conversion ratio was 1,26.

Abstract

The purpose of this study was to determine the best dose of papain in commercial feed to increase the growth of Climbing perch (Anabas testudineus). The research container used was a black bucket with a round shape with a volume of 100 L with a stocking density of 20 fish/container or 400 fish/m3. This study used an experimental method with a completely randomized design (CRD) with one factorial, five treatments and three replications. The treatment applied was feeding containing papain enzyme with different doses, namely P0= without the addition of papain enzyme, P1= addition of papain enzyme 1.25%/kg feed, P2= addition of papain enzyme 2.25%/kg feed, P3= papain enzyme 3.25%/kg feed and P4= addition of papain enzyme 4.25%/kg feed. The results showed a significant effect (P<0.05) on absolute weight, absolute length, specific growth rate, feed conversion ratio, enzyme activity and there was no significant effect (P>0.05) on the survival rate. The best growth rate was found in treatment P3 with absolute weight value: 4.70±0.18 g, absolute length: 2.0±0.20 cm, specific growth rate: 2.21±0.02% per day, survival: 100 %, feed conversion ratio: 1.26±0.03 %, and number of enzymes: 0.0716±0.0007 IU/mL, and with the growth of the average weight of water spinach 60.08 g and the average length of water spinach 100.4 cm in P1 treatment.

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian probiotik EM₄ (Effective microorganism) dengan dosis yang berbeda terhadap pertumbuhan dan kelangsungan hidup ikan gabus (Channa striata). Penelitian ini menggunakan metode rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dengan masing-masing tiga ulangan, yaitu perlakuan P0 tanpa penambahan dari probiotik (kontrol), perlakuan P1 dengan dosis 10 mL/kg pakan, perlakuan P2 dengan dosis 15 mL/kg pakan dan P3 dengan 20 mL/kg pakan. Parameter yang diamati yaitu pertumbuhan bobot mutlak, pertumbuhan panjang mutlak, kelulushidupan, rasio konversi pakan dan parameter kualitas air. Perlakuan terbaik didapat pada P2 dengan dosis 15 mL/kg pakan dengan pertumbuhan bobot mutlak sebesar 6,15±0,04 g, pertumbuhan panjang mutlak sebesar 6,23±0,15 cm, laju pertumbuhan spesifik sebesar 4,10±0,04%/hari, tingkat kelulushidupan sebesar 100±0,00%, rasio konversi pakan sebesar1,51±0,02 kg, kecernaan pakan sebesar 64,78%. Parameter kualitas air yang diukur selama penelitian didapatkan suhu berkisar antara 28,2-29,7°C, Derajat keasaman (pH) air berkisar antara 5,9-7,3, kandungan oksigen terlarut (DO) berkisar antara 4,7-6,0 mg/L dan amonia berkisar antara 0,0287-0,0740 mg/L. Parameter kualitas air yang didapat selama penelitian masih mendukung untuk pertumbuhan dan kelulushidupan ikan gabus.

Abstract

Ikan molly dikalangan pecinta ikan hias akuarium memang sudah populer. Ikan molly jantan memiliki bentuk ekor yang berbeda dengan ikan betina karena rata-rata ikan jantan memiliki bentuk ekor bercabang, para pembudidaya ikan molly sering menyebutnya dengan istilah lyretail, bentuk ekor ini memiliki nilai jual yang berbeda. Oleh karena itu, produksi ikan molly jantan menjadi fokus kegiatan budidaya ikan molly. Salah satu upaya untuk memenuhi permintaan yang tinggi dengan melakukan maskulinisasi ikan molly menggunakan madu, penelitian ini dilakukan dengan menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 4 kali ulangan. Perlakuan yang diberikan adalah dosis 0 mL/L, dosis 9 mL/L, dosis 10 mL/L, dosis 11 mL/L, dan dosis 12 ml/L. Penelitian ini dilaksanakan pada bulan Juli hingga September 2023. Bertempat di Laboratorium Teknologi Budidaya Perairan, Fakultas Perikanan dan Kelautan, Universitas Riau. Hasil penelitian menunjukkan bahwa perendaman menggunakan madu pada induk ikan molly yang sedang bunting dengan dosis yang berbeda berpengaruh nyata (p<0,05) terhadap persentase ikan molly jantan. Persentase ikan molly jantan pada perlakuan dosis 0 mL/L sebesar 22,35%, dosis 9 mL/L sebesar 46,53%, dosis 10 ml/L sebesar 49,56%, dosis 11 mL/L sebesar 49,95% dan dosis 12 mL/L sebesar 52,81%. Kualitas air pada media pemeliharaan berada pada kisaran normal untuk budidaya ikan molly. Simpulan penelitian ini adalah pemberian madu dengan dosis yang berbeda dengan metode perendaman memberikan pengaruh yang nyata terhadap keberhasilan maskulinisasi ikan molly dan dosis madu terbaik diperoleh pada dosis 12 mL/L.
