Selain itu probiotik juga dapat digunakan dalam pakan ikan. Tujuan penelitian adalah mengetahui efektivitas pemanfaatan probiotik dan enzim papain dalam pakan terhadap pertumbuhan dan nilai kecernaan pakan untuk ikan kerapu hibrid “cantik”. Perlakuan berupa penggunaan probiotik dalam pakan yaitu (pakan A) probiotik dalam pakan, (pakan B) tanpa probiotik dan tanpa enzim dalam pakan (kontrol), (pakan C) enzim dalam pakan dan (pakan D) kombinasi probiotik dan enzim dalam pakan. Hewan uji berupa benih ikan kerapu hibrid dengan ukuran bobot rata rata awal 7,30± 0,60 g. Ikan dipelihara dalam bak polikarbonat bervolume 300 liter yang telah dilengkapi dengan aerasi dan sistem air mengalir dengan kepadatan 50 ekor/bak. Benih ikan diberi pakan percobaan secara satiasi dengan frekuensi pemberian dua kali sehari. Percobaan dirancang dengan rancangan acak lengkap, terdiri atas empat perlakuan pakan dan tiga ulangan. Pengamatan pertumbuhan dilakukan setiap 1 minggu dengan menimbang bobot ikan. Pengamatan meliputi performa pertumbuhan, nilai kecernaan pakan pada ikan kerapu. Hasil penelitian menunjukkan bahwa penggunaan bakteri probiotik pada pakan ikan kerapu berpengaruh terhadap performa pertumbuhan (pertambahan bobot), efisiensi pakan (p<0.05). Pertambahan bobot tertinggi terjadi pada ikan kerapu hibrid yang diberi perlakuan pakan dengan bakteri probiotik (237±0,04%) diikuti pakan dengan enzim (204±0,09%), sedangkan ikan yang diberi pakan dengan kombinasi bakteri probiotik dan enzim diperoleh pertambahan bobot lebih rendah dari pakan kontrol masing masing 118±0,03% dan 192±0,20% dan nilai kecernaan pakan sebesar 79,91-84,24%. Probiotics have been widely used to improve water quality in fish farms. Probiotics are also utilized in fish feed as food supplements. This research was aimed to investigate the efficacy of probiotics and papain enzyme on the growth and nutrient digestibility of hybrid grouper “Cantik”. The experiment was arranged in a Completely Randomized Design consisting of four feed treatments and three replications: diet A, a diet supplemented with probiotic; diet B(control), a diet without supplementation of probiotic and enzyme; diet C, a diet supplemented with enzyme; and diet D, a diet supplemented with probiotic and enzyme. The test fish were hybrid grouper fish fry with an initial average body weight of 7.30 ± 0.60 g. The fish fry were reared in 300 liter volume polycarbonate tanks equipped with aeration and a flowthrough water system at a density of 50 fish/tank. The fish fry were fed with the diets two times a day by satiation for 56 days. The fish growth performance was observed weekly by recording their weight gain, nutrient digestibility, and survival rate.

Upaya meningkatkan kelangsungan hidup benih yang hingga saat ini belum stabil. Perkembangan tulang belakang benih ikan tuna merupakan satu di antara parameter yang perlu diamati mengingat sangat erat hubungannya dengan faktor pertumbuhan dan kelangsungan hidupnya. Metode pewarnaan ganda terhadap tulang belakang benih ikan tuna dengan menggunakan larutan Alcian Blue dan Alizarin Red-S telah digunakan dalam penelitian ini dengan mengambil sampel hewan uji setiap lima hari mulai D-5 sampai D-40. Hasil pengamatan menunjukkan bahwa tulang belakang benih ikan tuna pada D-25—D-30 mengalami transisi dari tulang muda menjadi tulang keras, dan berkembang menjadi tulang keras yang sempurna dan kokoh pada D-35—D-40, dengan performansi yang lebih agresif. Perkembangan tulang belakang benih ikan tuna mempunyai korelasi yang positif terhadap pertumbuhan dan kelangsungan hidupnya. Since 2003, the Institute for Mariculture Research and Fisheries Extension, Gondol has carried out breeding research on yellowfin tuna, Thunnus albacares (Bonnaterre 1788). Various studies on the morphology, physiology, and enzymatic processes of the fish fry were conducted to gain basic information about vertebral development of yellowfin tuna which was suspected to positively affect the growth and survival rate of the fish. Among the parameters involved in the growth and survival rate of tuna fry is vertebral development. A double staining method on tuna fry vertebrae using Alcian Blue and Alizarin Red-S solutions was used in this study, and samples of fry were collected every five days starting from D-5 up to D-40. The result showed that the seeds had vertebral transitions from cartilage to bone on D-25—D-30, followed by the development of hard-bone on D-35—D-40 with a significant increase of aggressive activity.

Kemudian, hasil produksi ikan nila srikandi yang diberi pakan mandiri mencapai 2.214 ± 172,69 kg dan pakan komersil 2.248,5 ± 234,85 kg. Berdasarkan hasil analisis usaha penggunaan pakan mandiri pada budidaya nila srikandi lebih direkomendasikan dibandingkan dengan pakan komersil. The purpose of this study was to determine the effects of locally-produced and commercial feeds on the growth of Srikandi tilapia cultured in fish farming areas of Brebes Regency, Central Java. Tilapia Srikandi were cultured in three ponds sized approximately ± 3,000 m2. Each pond was divided into two sections divided by a net, which resulted in six experimental plots. Each experimental plot was stocked with 10,000 fish seeds. Srikandi tilapia were maintained for four months and given daily feed as much as 1%-2% of body weight with feeding time at 07.00, 12.00, and 17.00. The fish were given test feeds in the 1st and 2nd month as much as 1% of body weight. The feeding level was increased to 2% in the 3rd and 4th months. The performances of Srikandi tilapia (growth, growth rate, and survival) fed with the two feed types were tested using the T-test. The results showed that there was no statistically significant difference on growth performance between fish fed with locally-produced feed and commercial feed (P>0.05). The total harvest of Srikandi tilapia fed with the locally produced feed reached 2,214 ± 172.69 kg and 2,248.5 ± 234.85 kg for the commercial feed. This study suggests that in terms of economic efficiency, the use of the locally-produced feed in Srikandi tilapia farming is more profitable compared to the use of commercial feed.","PeriodicalId":334563,"journal":{"name":"Media Akuakultur","volume":"52 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120882929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aplikasi haematococcus telah dilakukan pada larva kerapu sunu dan menunjukkan adanya perbaikan peformansi warna merah yang cukup signifikan. Tujuan dari penelitian ini adalah mengetahui pengaruh haematococcus sebagai sumber astaxanthin terhadap pertumbuhan, total karotenoid, dan profil darah (hematokrit dan haemoglobin) pada juvenil ikan kerapu sunu. Benih kerapu sunu ukuran panjang rata-rata 14,07 ± 0,07 cm dan bobot rata-rata 45,92 ± 6,35 g dipelihara dalam jarring berukuran 0,5 m x 0,5 m x 1 m yang diletakkan dalam bak beton ukuran 3 m x 1,2 m x 1,2 m. Kepadatan ikan tiap jaring adalah lima ekor. Perlakuan yang diujicobakan adalah penambahan haematococcus ke dalam pakan buatan dengan dosis dan kompisisi sebagai berikut: A) 1% dari berat pakan, B) 1% dari berat pakan + 10% minyak ikan, dan C) 0% (kontrol). Hasil penelitian menunjukkan bahwa penambahan haematococcus ke dalam pakan tidak memberikan perbedaan nyata terhadap pertumbuhan mutlak panjang dan bobot, serta laju pertambahan panjang dan bobot (P value > 0,05). Penambahan haematococcus memberikan perbedaan nyata (P value 0.05). The addition of haematococcus gave a significant difference (P-value < 0.05) to feed conversion ratio between treatment A, B and C with the values of 1.99 ± 0.09, 2.12 ± 0.14, and 2.28 ± 0.09, respectively. The addition of haematococcus also increased the levels of total carotene content, hematocrit, and hemoglobin. This study suggests that the application of haematococcus could significantly improve the red color performance of trout grouper larvae.","PeriodicalId":334563,"journal":{"name":"Media Akuakultur","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125746783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
