Pemuliaan ikan lele Afrika, Clarias gariepinus melalui seleksi individu selama tiga generasi telah menghasilkan strain baru ikan lele tumbuh cepat yang diberi nama Mutiara. Pemijahan induk ikan lele Mutiara dapat menghasilkan benih albino. Keragaan zooteknis dan karakteristik fenotipe-morfologis ikan lele Mutiara albino perlu dieksplorasi untuk mengevaluasi potensi pengembangannya. Penelitian ini bertujuan mendapatkan informasi keragaan pertumbuhan, sintasan, hubungan panjang-bobot, faktor kondisi, dan karakteristik biometrik ikan lele Mutiara albino dibandingkan yang berwarna normal. Pengamatan keragaan pertumbuhan dilakukan selama 20 hari tahap pemeliharaan larva, 30 hari tahap pendederan dan 45 hari tahap pembesaran. Analisis hubungan panjang-bobot dan faktor kondisi, serta karakterisasi biometrik dilakukan pada akhir tahap pembesaran. Hasil penelitian ini menunjukkan bahwa keragaan pertumbuhan ikan lele Mutiara albino berdasarkan parameter bobot selama tahap pemeliharaan larva, pendederan, dan pembesaran tidak berbeda dari yang berwarna normal (P>0,05); sedangkan keragaan pertumbuhan berdasarkan parameter panjang totalnya lebih rendah (P<0,05). Sintasan ikan lele Mutiara albino selama tahap pemeliharaan larva, pendederan, dan pembesaran tidak berbeda (P>0,05) dari yang berwarna normal. Hubungan panjang-bobot ikan lele Mutiara albino bersifat alometrik positif (W = 0,0021L3,45), sama dengan yang berwarna normal (W = 0,0044L3,16). Ikan lele Mutiara albino memiliki tubuh yang lebih gemuk (faktor kondisi sebesar 0,88 ± 0,08) dibandingkan yang berwarna normal (faktor kondisi sebesar 0,73 ± 0,05). Secara biometrik, ikan lele Mutiara albino memiliki proporsi kepala yang lebih besar dan jumlah jari-jari sirip punggung dan sirip dubur yang lebih sedikit dibandingkan yang berwarna normal. Secara umum, keragaan aspek zooteknis ikan lele Mutiara albino relatif sama dengan yang berwarna normal, sehingga potensial sebagai komoditas budidaya.A breeding program of the African catfish, Clarias gariepinus via three generations of individual selection resulted in a new fast-growing strain, namely Mutiara. Breeding of the Mutiara African catfish might result in albino individuals. Zootechnical and morphological-phenotypic performances of the albino should be evaluated to determine its potential as an aquaculture strain. The present study aimed to obtain information on the growth performance, survival, length-weight relationship, condition factors, and biometric characteristics of the albino compared to those of the normal ones. The growth performance was observed during 20 days of larval rearing, 30 days of nursery, and 45 days of grow-out phases. While, length-weight relationship, condition factors, and biometric characteristics were measured at the end of the grow-out phase. The present study revealed that the growth performance of the albino based on body weight during larval rearing, nursery, and grow-out phases was not different (P>0.05), whereas its growth performance based on total length was inferior (P<0.05) to that of the normal ones. The survival rate of the albino during larval rearing, nursery, and grow-out phases was not different (P>0.05) to that of the normal ones. Length-weight relationship of the albino was positive allometric (W = 0.0021L3.45), similar to that of the normal ones (W = 0.0044L3.16). The albino was more rotund (condition factor of 0.88 ± 0.08) compared to the normal ones (condition factor of 0.73 ± 0.05). Biometrically, the albino has a bigger head portion and fewer dorsal and anal fin rays than the normal ones. In general, the zootechnical aspect of albino Mutiara African catfish is relatively similar to that of the normal ones meaning that it has the potential to be considered as an aquaculture strain candidate.

Akuaponik adalah budidaya ikan dan tanaman hidroponik yang dipelihara bersama dalam satu sistem yang terintegrasi. Limbah budidaya ikan yang berasal dari sisa pakan dan metabolisme akan menghasilkan NH3 yang dalam dosis tertentu dapat meracuni ikan. Penggunaan tanaman dalam sistem akuaponik akan mereduksi konsentrasi NH3 sehingga meningkatkan kualitas air yang pada akhirnya akan mengoptimalkan pertumbuhan ikan. Penelitian ini bertujuan untuk mengetahui pertumbuhan ikan mas koki, Carrasius auratus, pertumbuhan tanaman yang dipelihara pada sistem akuaponik dengan jenis tanaman air berbeda. Sebanyak 20 ekor ikan mas koki, berukuran panjang total 2,79 ± 0,25 cm dan bobot 0,24 ± 0,083 g ditebar per wadah. Wadah yang digunakan berupa 12 pasang yang setiap pasangnya terdiri atas akuarium untuk tanaman air dan galon plastik volume 17 L untuk ikan mas koki yang dirangkai menggunakan sistem resirkulasi tertutup. Penelitian didesain dalam rancangan acak lengkap (RAL) yang terdiri atas empat perlakuan dan tiga ulangan. Perlakuan yang diberikan adalah tiga jenis tanaman air berbeda yaitu: (1) ikan mas koki + tanaman melati air (Echinodorus palifolius); (2) ikan mas koki + tanaman air anubias (Anubias barteri); (3) ikan mas koki + tanaman bacopa (Bacopa australis); dan (4) ikan mas koki tanpa ada tanaman air. Parameter yang diamati adalah pertumbuhan ikan dan tanaman air, sintasan ikan, dan kualitas air. Hasil penelitian menunjukkan bahwa panjang total dan bobot ikan mas koki (7,50 ± 0,05 cm dan 5,21 ± 0,10 g) yang dipelihara dalam sistem akuaponik dengan tanaman melati air lebih tinggi dan berbeda nyata (P<0,05) dibanding kontrol (7,19 ± 0,16 cm; dan 4,64 ± 0,23 g). Kadar amonia pada perlakuan tanaman melati air (0,411 mg/L) lebih rendah dibanding kontrol (0,630 mg/L), karena akar tanaman menyerap amonia di air, tanaman hias air dapat digunakan dalam sistem akuaponik ikan air tawar.Aquaponics is the cultivation of fish and hydroponic plants together in one integrated system. Fish farming wastes sourced from uneaten feed and faecal materials produce ammonia (NH3) of which in certain doses can poison the fish. The use of plants in aquaponic systems will keep the concentration of NH3, at a balanced level thereby increasing water quality which will optimize the fish growth. This study aimed to determine the growth of gold fish, Carrasius auratus reared in aquaponic systems using different types of aquatic plants. A total of 20 gold fish (total length of 2.79 ± 0.25 cm and weight of 0.24 ± 0.083 g) were reared per tanks. A pair of containers was used consisted of aquariums for aquatic plants and plastic gallons (volume 17 L) for gold fish arranged in a closed recirculation system. The total number of containers used were 12 pairs. The experiment was arranged using a completely randomized design (CRD) consisting of four treatments and three replications. The treatments consisted of: (1) gold fish + Echinodorus palifolius; (2) gold fish + Anubias barteri; (3) gold fish + Bacopa australis; and (4) gold fish without aquatic plants (control). The parameters observed were growth of gold fish and aquatic plants, survival rate of gold fish, and water quality. The results showed that the total length and weight of gold fish (7.50 ± 0.05 cm and 5.21 ± 0.10 g) reared in an aquaponic system with water jasmine plants were higher and significantly different (P<0.05) compared to control (7.19 ± 0.16 cm, and 4.64 ± 0.23 g). Ammonia level in treatment of E. palifolius (0.411 mg/L) was lower than control (0.630 mg/L) because plant roots absorb ammonia in water. Ornamental aquatic plants can be used in aquaponics systems for freshwater fish.

Upaya meningkatkan performa budidaya ikan mas dapat dilakukan melalui seleksi. Salah satu faktor keberhasilan program seleksi adalah tingkat keragaman genetik yang tinggi pada populasi bahan seleksi. Penelitian ini bertujuan membentuk dan mengevaluasi keragaan populasi dasar (F-0) ikan mas sebagai populasi awal dalam kegiatan seleksi. Materi kegiatan ini adalah populasi sintetis yang merupakan penggabungan lima strain ikan mas, yakni Majalaya, Rajadanu, Sutisna, Wildan, dan Sinyonya. Pembentukan populasi dasar (F-0) dilakukan menggunakan metode seleksi berdasarkan indeks individu dari empat karakter fenotipik, yakni panjang, tebal, tinggi, dan bobot. Masing-masing karakter diberi nilai 1:1:1:2. Titik cut-off seleksi populasi dasar (F-0) sebesar 60%. Hasil penelitian menunjukkan bahwa populasi F-0 ikan mas yang dibentuk terdiri atas individu hasil seleksi sebanyak 1.662 ekor, dengan komposisi 723 jantan dan 939 betina. Populasi dasar (F-0) sintetis hasil seleksi tersebut mempunyai keragaman genetik lebar karena diperoleh dari 25 populasi hasil persilangan dalam proporsi yang berbeda-beda. Kontribusi genetik paling besar dalam pembentukan populasi F-0 tersebut diberikan oleh strain Sutisna (22,55%) diikuti Majalaya (21,52%), Rajadanu (20,84%), Wildan (18,33%), dan Sinyonya (16,75%). Tingginya tingkat keragaman genetik populasi dasar ini berpotensi besar dalam keberhasilan kegiatan pemuliaan ikan mas khususnya melalui program seleksi.Improvement on phenotipic characters in common carp culture can be achieved through selection. In order to achive that goal, A base population (F-0) must be initially formed. This study aimed to establish and evaluate the performance of base populations (F-0) common carp. The synthetic populations had been created which were the combinations of five common carp strains, namely Majalaya, Rajadanu, Sutisna, Wildan, and Sinyonya. These common carp base populations (F-0) were created through a selection based on the individual index of four phenotypic characters, i.e. length, thickness, height and weight, which scored 1:1:1:2, respectively. The selection cut-off in this program was 60%. The results showed that the base populations (F-0) of common carp formed from 1,662 selected fish consisted of 723 males and 939 females. These F-0 populations have wide genetic diversity as the crossing results of 25 populations with different proportions. The Sutisna strain (22.55%) had the most genetic contribution in the formation of the F-0 populationss followed by Majalaya (21.52%), Rajadanu (20.84%), Wildan (18.33%), and Sinyonya (16.75%). High level of genetic variation in this base population has great potential in the success of common carp breeding activities, especially trough selection program.

Tujuan penelitian ini adalah untuk mengevaluasi efektivitas suplementasi ekstrak serbuk sari pinus melalui pakan terhadap maskulinisasi dan kinerja reproduksi ikan gapi. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri atas lima perlakuan dengan tiga ulangan, yaitu meliputi suplementasi 10 mg ekstrak serbuk sari pinus per kg pakan (SSP10), 50 mg kg-1 pakan (SSP50), 250 mg kg-1 pakan (SSP250), 1 mg 17b-metiltestosteron per kg pakan sebagai kontrol positif (MT atau kontrol-2), dan perlakuan tanpa suplementasi ekstrak serbuk sari pinus (kontrol-1). Ikan uji yang digunakan adalah induk gapi bunting diberi pakan perlakuan selama 15 hari dan dipelihara sampai anak kelahiran pertama (B1) dan kedua (B2). Hasil penelitian menunjukkan bahwa pemberian ekstrak serbuk sari pinus mampu meningkatkan persentase nisbah kelamin jantan pada B1, namun tidak pada B2. Suplementasi ekstrak serbuk sari pinus pada induk bunting tidak memengaruhi kinerja reproduksi. Persentase nisbah kelamin jantan B1 pada perlakuan SSP50 dan SSP250 tidak berbeda nyata, secara berurutan 63,9% dan 66,4%; tetapi keduanya lebih tinggi dibandingkan kontrol-1 (31,3%); namun masih lebih rendah dibandingkan perlakuan MT (81,9%) (P<0,05). Perlakuan MT pada B2 memiliki nisbah kelamin jantan tertinggi (48,4%) dan berbeda nyata dengan perlakuan lainnya (P<0,05). Suplementasi ekstrak serbuk sari pinus melalui pakan efektif dalam meningkatkan persentasi nisbah kelamin jantan ikan gapi pada dosis 50 mg kg-1. Ekstrak serbuk sari pinus dapat digunakan untuk maskulinisasi ikan gapi.The aim of this study was to evaluate the effectiveness of pine pollen extract supplementation through feed on masculinization and reproductive performance of guppy. This study used a completely randomized design consisting of five treatments with three replications. The treatments were the supplementation of pine pollen extract of 10 mg kg-1 of feed (SSP10), 50 mg kg-1 of feed (SSP50), and 250 mg kg-1 of feed (SSP250). Control treatments consisted of the supplementation of 1 mg 17b-methyltestosterone per kg of feed as a positive control (MT or control-2), and without supplementation pine pollen extract in feed (control-1). The test fish used were livebearer guppy brooders. The test fish were given treatment feed for 15 days and continued until the first (B1) and second (B2) offsprings were born. This study showed that the administration of pine pollen extract in feed was able to increase the percentage of male sex ratio in B1, but not in B2. Supplementation of pine pollen extract did not affect the tested fish’s reproductive performance. The percentages of male sex ratio B1 in the SSP50 and SSP250 treatments were not significantly different, 63.9% and 66.4%, respectively. Despite that, both treatments had a higher male sex ratio than control-1 (31.3%), yet lower than the MT treatment (81.9%) (P<0.05). The MT treatment at B2 had the highest male sex ratio (48.4%) and was significantly different from the other treatments (P<0.05). Supplementation of pine pollen extract through feed at a dose of 50 mg kg-1 effectively increased the male sex ratio of guppy. Pine pollen extract can be used for the masculinization of guppy.

Penggunaan sumber kalsium sintetik dengan ukuran partikel yang relatif besar di tambak diduga menyebabkan ketidaksempurnaan moulting pada budidaya udang vaname, Litopenaeus vannamei. Salah satu sumber yang berkelanjutan untuk memenuhi kebutuhan kalsium selama proses moulting adalah limbah cangkang dari biota perairan budidaya lainnya. Penelitian ini bertujuan untuk mengevaluasi penggunaan sumber kalsium dari cangkang moluska yang berbeda terhadap performa moulting dan pertumbuhan udang vaname. Penelitian dilaksanakan pada bulan Agustus-September 2021 bertempat di Laboratorium Hatchery dan Teknologi Budidaya Fakultas Pertanian, Universitas Malikussaleh. Penelitian menggunakan rancangan acak lengkap (RAL) non-faktorial dengan empat perlakuan tiga ulangan, yakni: A (penambahan tepung cangkang tiram 75 mg/L), B (penambahan tepung cangkang kepiting 75 mg/L), C (penambahan tepung cangkang remis 75 mg/L), dan D (kontrol), masing-masing tiga ulangan. Tahapan-tahapan dalam membuat tepung yaitu pencucian, penjemuran, penumbukan, pengayakan, dan pembuatan nannokalsium (furnace). Parameter yang diamati selama penelitian antara lain: jumlah individu moulting, kecepatan moulting, laju pertumbuhan harian, dan kandungan kalsium cangkang. Hasil penelitian menunjukkan bahwa perlakuan terbaik terdapat pada perlakuan A (penambahan tepung cangkang tiram 75 mg/L) menghasilkan jumlah individu moulting sebesar 77,50%; kecepatan moulting 2,00 hari; laju pertumbuhan harian 3,31%; dan tingkat sintasan 93,33%. Penelitian ini menghitung bahwa 1 ha tambak udang membutuhkan 6 kg tepung cangkang untuk mencukupi kebutuhan kalsium udang budidaya. Parameter kualitas air tambak yang diukur (suhu, pH, oksigen terlarut, salinitas, dan amonia) menunjukkan nilai optimal untuk pertumbuhan udang vaname. Penelitian ini menyimpulkan bahwa kalsium dari cangkang tiram paling baik dalam meningkatkan proses moulting udang vaname dan merekomendasikan penggunaannya sebagai alternatif sumber kalsium untuk menggantikan kalsium dari batu gamping.The use of synthetic calcium sources with relatively large particle sizes in brackishwater ponds is suspected of causing moulting imperfection in cultured Pacific white shrimp, Litopenaeus vannamei. One of the sustainable sources to supply calcium needs during the moulting process is the shell waste from other farmed aquatic biota. This study aimed to evaluate the use of calcium sources from different mollusk shells on the moulting and growth performance of Pacific white shrimp. The research was conducted between August-September 2021 at the Hatchery and Cultivation Technology Laboratory, Faculty of Agriculture, Malikussaleh University. The study used a non-factorial completely randomized design (CRD) with four treatments, namely: the addition of A (75 mg/L oyster shell flour), B (75 mg/L crab shell flour), C (75 mg mussel shell flour), and D (control, 0 mg/L of shell flour) in the rearing media with three replications. The shell flour was transformed into nano-calcium via different production stages. The parameters observed during the study included: number of moulting individuals, moulting rate, daily growth rate, and shell calcium content. The results showed that the best treatment was in treatment A (addition of oyster shell flour 75 mg/L) resulted in the number of moulting individuals of 77.50%; moulting rate of 2.00 days; daily growth rate of 3.31%; and a survival rate of 93.33%. This study calculated that 1 ha of shrimp pond required 6 kg of shell flour to sufficiently supply the calcium demand of cultured shrimp. The measured ponds’ water quality parameters (temperature, pH, dissolved oxygen, salinity, and ammonia) showed optimal values for the growth of Pacific white shrimp. This study concludes that calcium from oyster shell has the best in improving the moulting process of Pacific white shrimp and recommends its use as an alternative source of calcium to replace calcium from limestone.

Siput gonggong, Laevistrombus turturella termasuk komoditas perikanan laut yang memiliki nilai ekonomi tinggi di Pulau Bintan Provinsi Kepulauan Riau. Hemolim pada siput berperan penting dalam sistem pertahanan tubuh dan reproduksi. Penelitian ini bertujuan untuk mengetahui total hemosit dan diferensial hemosit pada siput gonggong asal Pulau Bintan. Penelitian dilaksanakan pada bulan Juli-Agustus 2021. Sampel siput gonggong berasal dari perairan laut Kampung Madong dan Lobam. Hemolim diambil dari otot kaki gonggong untuk pemeriksaan total hemosit dan diferensial hemosit. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan total hemosit, persentase hyalin dan sel granular siput gonggong dari Kampung Madong dan Lobam relatif sama dan dalam kisaran normal (< 1,0 x 106 sel/mm3). Jumlah total hemosit siput gonggong asal Kampung Madong dan Lobam secara berturut-turut adalah berkisar antara 77.000-166.600 sel/mm3 dan 71.000-165.000 sel/mm3, persentase sel hyalin berkisar antara, 58%-80% dan 52%-70%, serta persentase sel granular berkisar antara 20%-42% dan 30%-48%. Oleh karena nilai total hemosit dan diferensial hemosit relatif sama maka siput gonggong asal Kampung Madong disarankan sebagai kandidat calon induk karena memiliki ukuran tubuh 6,52 ± 5,61 cm lebih besar dibandingkan asal Lobam 5,27 ± 0,40 cm.Gonggong conch, Laevistrombus turturella is a marine gastropod highly valued as a seafood commodity in Bintan Island Riau Islands Province. The farming technology of the species is currently not available due to limited information on its biology including its immune system and reproduction. Hemolymph in conchs plays an important role in gonggong conch body’s defense system and reproduction. This study aimed to determine the total haemocytes and hemocytic differential of gonggong conchs originated from Bintan Island. The research was conducted between July-August 2021. The gonggong conch samples were collected from the coastal waters of Kampung Madong and Lobam. Hemolymph was taken from the gonggong conch leg muscles for examination of total hemocytes and hemocytic differential and analyzed descriptively. The results showed that the total hemocytes, percentage of hyaline and granular cells of gonggong conchs from Kampung Madong and Lobam were relatively similar and within the normal range (< 1.0 x106 cell/mm3). The total number of haemocytes of gonggong conchs from Kampung Madong and Lobam ranged from 77,000-166,600 cells/mm3and 71,000-165,000 cells/mm3; respectively, while the percentages of hyaline cells ranged between 58%-80% and 52%-70%, respectively, and the percentage of granular cells ranged between 20%-42% and 30%-48%. Gongong conch from Kampung Madong had a body size of 6.52 ± 5.61 cm which was larger than that of Lobam with body size of 5.27 ± 0.40 cm. Because both had relatively similar values of total haemocytic and haemocytic differential, the gonggong conch from Kampung Madong was suggested as the best candidate for broodstock.

Perkembangan teknologi dalam pembudidayaan ikan menggunakan sistem resirkulasi sangat cepat dalam beberapa tahun terakhir karena bersifat ramah lingkungan dan memberikan banyak keuntungan yaitu mampu memproduksi ikan dengan kepadatan tinggi. Namun, penurunan kualitas air akibat limbah dari feses dan sisa pakan dapat membahayakan sintasan ikan. Penelitian ini dilakukan untuk mengevaluasi kualitas air, khususnya konsentrasi amonia pada sistem resirkulasi budidaya ikan gurami, Osphronemus goramy melalui pemodelan dinamika sistem. Simulasi pemodelan dilakukan dengan software Vensim PLE menggunakan data sekunder. Selama 30 hari periode simulasi, konsentrasi amonia dalam kolam ikan meningkat sampai dengan hari ke-15, kemudian turun bertahap hingga hari ke-30. Konsentrasi amonia yang aman diperoleh dari laju resirkulasi 50 dan75 L/jam dengan sintasan ikan gurami 95%. Persentase eror sebesar 8,6% dibandingkan dengan data hasil penelitian sebelumnya menunjukkan bahwa model dinamika sistem ini valid dan dapat digunakan untuk pemantauan kualitas air, khususnya amonia, dalam budidaya ikan gurami yang menggunakan sistem resirkulasi.The development of recirculating aquaculture systems (RAS) has been rapidly increased in recent years due to environmental and economic advantages, i.e., the system can support farmed fish at high density. However, declining water quality in RAS could occur as a result of the accumulation and decomposition of fecal and uneaten feed materials that can be harmful to fish. This study was conducted to evaluate water quality, particularly the concentration of ammonia in the recirculation system of gouramy, Osphronemus goramy aquaculture through a system dynamics model. The model simulation was performed via Vensim PLE software using datasets from secondary sources. During the 30-days of simulation period, the ammonia concentration in the fish pond increased until day 15, then decreased gradually until day 30. Safe ammonia concentrations were obtained from recirculation rates of 50 and 75 L h-1 with gouramy survival rate of 95%. The percentage error of 8.6% compared to the previous experimental data shows that the prediction of the developed system dynamics model is valid and acceptable. The model can therefore be used for water quality monitoring, particularly for ammonia concentration in gouramy farming using recirculating aquaculture systems.
