Hatchery activities covered pond preparation, broodstock, brood spawning, egg removal, hatching eggs, naupli rearing, larvae rearing, natural feed culture, water quality management, pest and disease prevention, and larvae harvesting. The productivity from one parent of vaname shrimp is 300.000 eggs with FR 86 % and HR 85 %. The production of hatchery activities reached 2.607.428.880 shrimps year^-1 consisting of 360 cycles. Production resulting from hatchery activities is post-larvae 4 and 7 with SR 75 %. </p> Andri Iskandar Afrizal Rizki Andri Hendriana Giri Maruto Darmawangsa Abuzzar Abuzzar Khoerullah Khoerullah Muksin Muksin Copyright (c) 2020 Jurnal Perikanan Terapan https://creativecommons.org/licenses/by-sa/4.0 2021-11-26 2021-11-26 2 1 10.25181/peranan.v2i1.1655 https://jurnal.polinela.ac.id/PERANAN/article/view/2203 <p><em>The high population growth has led to less land for agriculture and fisheries, while the demand for food is increasing. The purpose of this study was to determine the survival rate of fish, daily growth rate, feed convertion ratio, character of aquaponic media, vegetable productivity, and water quality in a aquaponics.The results obtained by the survival rate at a fish density of 5 kg/bucket were 77-81%. The daily weight growth rate and feed convertion ratio at a fish density of 5 kg/bucket with feeding frequency of one time more effective. The character of the live system aquaponics media has many advantages, namely: water saving, simple system, no need for electricity, suitable for areas with minimal land, low investment costs, easy to implement, suitable for household production, the density of fish being raised is quite high. The productivity of vegetables is also good, the plant density is quite high, and good water quality. The aquaponics system of “kulkas hidup” can be used as a solution for food availability in densely populated areas, limited water areas and post-disaster areas.</em></p> <p>Keywords: Aquaponics, Kulkas Hidup, Food, Post Disaster</p> <p>&nbsp;</p> Tulas Aprilia Copyright (c) 2021 Jurnal Perikanan Terapan https://creativecommons.org/licenses/by-sa/4.0 2021-11-26 2021-11-26 2 1 10.25181/peranan.v2i1.2203 https://jurnal.polinela.ac.id/PERANAN/article/view/2186 <p>Koi fish is one of the ornamental fish commodities which is popularly cultivated in Indonesia. This fish has an attraction because of its very beautiful color and is often used as a contest fish. Every year the demand for koi fish continues to increase both in domestic and foreign markets so that it have promising business prospects. One of the prospects is in hatchery activities which include container preparation activities, broodstock maintenance, broodstock spawning, egg hatching, larval rearing, seed maintenance, denial maintenance, water quality management, pest and disease prevention, and harvesting. One of the koi fish hatcheries is Mizumi Farm, located in Sukabumi, West Java. The productivity of koi fish in that location includes the number of eggs produced around 116,452 eggs, 81% fertilization rate (FR), 75% hatching rate (HR), 63% larval survival rate (SR), 63% SR of seed / white matter and SR of denial. 74%. The results showed a total of fish is 634 tail with a size of 5 cm. Marketing of koi fish seeds at Mizumi Farm includes fostered partners, hobbyists in the Sukabumi area and other cities.</p> Andri Hendriana Fajar Ridwansyah Andri Iskandar Asep Syamsul Munawar Deni Lugina Copyright (c) 2021 Jurnal Perikanan Terapan https://creativecommons.org/licenses/by-sa/4.0 2021-11-26 2021-11-26 2 1 10.25181/peranan.v2i1.2186 https://jurnal.polinela.ac.id/PERANAN/article/view/2353 <p>Ikan gabus (<em>Channa striata</em>) merupakan jenis ikan air tawar yang sudah dikenal luas oleh masyarakat Indonesia. Selain itu, ikan gabus merupakan salah satu ikan air tawar yang berekonomis tinggi. Menurut Rakhmawati (2015), harga ikan gabus secara umum berkisar antara Rp. 42.000–Rp. 45.000 per kg dipasar lokal dan Rp. 250.000-Rp. 300.000 untuk ekspor. Semakin tinggi permintaan pasar terhadap ikan gabus, maka aktifitas penangkapan ikan gabus di alam juga semakin meningkat. Hal tersebut dapat menurunkan populasi ikan gabus di alam, sehingga perlu adanya upaya untuk membudidayakan ikan gabus.Pendederan ikan gabus dengan pemberian cacing darah beku mampu menghasilkan benih yang ukuranya tidak jauh berbeda dengan benih ikan gabus yang diberikan cacing sutra.Pendederan ikan gabusdilaksanakan selama 28hari menggunakan 2 akuarium dengan padat tebar 1 ekor/liter. Tingkat kelangsungan hidup pada masing-masing perlakuan yaitu 85% (Akuarium A) dan 90% (Akuarium B). Hasil pengamatan suhu di masing-masing perlakuan berkisar 27-31ºC, Nilai pH selama pemeliharaan berkisaran 6,5-7,5, Kadar oksigen terlarut dalam media pemeliharaan yaitu 5,8-6,5 ppm.</p> Gerald Dean Santoro Adni Oktaviani Epro Barades Copyright (c) 2022 https://creativecommons.org/licenses/by-sa/4.0 2021-11-10 2021-11-10 2 1 https://jurnal.polinela.ac.id/PERANAN/article/view/2357 <p>Ikan gurame merupakan jenis ikan konsumsi yang banyak diminati. Akan tetapi dalam budidaya memiliki kendala yaitu pertumbuhannya yang lambat. Salah satu pemecahan masalahnya adalah dengan pemanfaatan probiotik pada pakan. Probiotik merupakan mikroba hidup yang bersifat menguntungkan dan memberikan dampak bagi peningkatan keseimbangan mikroba saluran usus ikan dan memperbaiki kualitas air. Dosis probiotik yang diberikan 4ml/1 kg pakan dengan cara menyemprotkan ke permukaan pakan yang diberikan. Sebelum dilakukan penyemprotan, bakteri probiotik dicampurkan dengan molase 100 ml dan air tawar sebanyak 12ml kemudian disemprotkan ke 1 kg pakan yang kemudian di kering anginkan. Pemeliharaan benih ikan gurame dilakukan di kolam beton ukuran 3x1 m dan padat penebaran perlakuan yaitu 60 ekor/m² yang dipelihara selama 40 hari. Benih gurame diberi makan 3 kali sehari sebanyak 5% dari bobot biomassa. Selama pemeliharaan hasil pertumbuhan yang didapatkan yaitu pertambahan panjang dari awal tebar 3,93 cm sampai panen 6,60 cm. Pertambahan berat dari 2,85 g sampai 5,75 g. Laju pertumbuhan panjang harian mencapai 0,3-2,8%, nilai FCR (<em>Food Convertion Ratio</em>) 1,8 serta tingkat kelulusan hidup ikan gurame mencapai 53,5%.</p> Ari Yudatama Pindo Witoko Dian Febriani Copyright (c) 2022 https://creativecommons.org/licenses/by-sa/4.0 2021-10-08 2021-10-08 2 1 10.25181/peranan.v2i1.2357 https://jurnal.polinela.ac.id/PERANAN/article/view/2358 <p>Udang vaname (<em>Litopenaeus vannamei</em>) Stadia Post Larva sangat rentan terhadap Pertumbuhan dan Sintasan Sehingga Pakan Biasa tidak cukup untuk memenuhi Kelangsungan Hidup udang vaname. Dengan Keadaan tersebut kita dapat memanfaatkan Pengaplikasian Probiotik Em4 dan <em>Bacillus </em>sp terhadap pakan buatan dengan Tujuan Untuk Mengetahui Pertumbuhan dan Kelangsungan Hidup udang vaname. Penelitian ini Bertujuan untuk mengetahui Keberhasilan Pemberian Probiotik em4 dan<em>Bacillus </em>sp pada Pakan Buatan dan melakukan perbandingan dengan pemberian pakan pada udang tanpa pengaplikasian Probiotik. yang dilakukan adalah Persiapan Media, Pembuatan dan Penambahan <em>Bacillus </em>sp pada pakan Udang, Penebaran benur, pemeliharaan udang, pengamatan sampling, pengamatan kualitas air, dan Pemanenan. penebaran benur sebanyak 50 ekor dalam 1 Akuarium stadia post larva 7 udang vaname dan pemberian Probiotik Bacillus sp dengan Dosis 20 mL/kg pakan dan dosis em4 dengan dosis 15 ml/kg pakan. Data Survival Rate (SR) Akuarium Pemberian Probiotik <em>Bacillus </em>sp pada pakan buatan Udang Vaname yaitu 80%, Berat rata-rata 2,96 gram, Pertumbuhan Panjang Udang rata-rata 10,4. kemudian data Survival Rate (SR) Akuarium terkontrol yaitu 60%, berat rata-rata 2,77 gram, pertumbuhan panjang rata-rata 7,39 cm. kemudian untuk hasil dengan penambahan probiotik em4 data Survival Rate (SR) Akuarium Pemberian Probiotik em4 pada pakan buatan Udang Vaname yaitu 64 %, Berat rata-rata 3,11 gram, Pertumbuhan Panjang Udang rata-rata 9,07 cm.</p> Yoka Agustama Tiara Abung Lestari Aldi Huda Verdian Pindo Witoko Eulis Marlina Copyright (c) 2022 https://creativecommons.org/licenses/by-sa/4.0 2021-09-09 2021-09-09 2 1
