Abstract

Striped catfish tetraploid induction through heat shock that carried out in this study is not intended to produce on growth fries.But to form a broodstock to produce triploid on growth fries through cross breeding without any physical shock induction process.The fries from the heat shock induction in the previous study were screened or selected by observing the maximum number of nucleoli in fin cells.The number of tetraploid individuals used in the performance test was 105 which were placed in three different concrete tanks.The results showed that the growth of tetraploid striped catfish was more significant than diploid with a difference in the daily weight percentage about 0.497% and 0.158% for length but insignificant differences in FCR and SR.In gonadal development based on histological observations, it was shown that each tetraploid and diploid both male and female striped catfish were at the same level of gonadal maturity.Female gonads were at the previtellogenic oocytes and vitellogenic oocytes, but males are dominated at the stage of spermatocytes and spermatozoa.This histology also shows us that the female gonad was still at the development stage, while the male had entered the mature stage and ready to be spawned.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh konsumsi harian yang berbeda terhadap pertumbuhan dan kelangsungan hidup dari dua strain ikan nila. Penelitian ini telah dilaksanakan pada tanggal 18 Oktober – 17 November Tahun 2012 yang bertempat di Laboratorium Hatcheri dan Teknologi Budidaya, Universitas Malikussaleh Lhokseumawe. Ikan uji yang digunakan berupa benih ikan nila gift dan nila merah yang berukuran 7 – 8 cm. Adapun metode yang digunakan adalah Rancangan Acak Lengkap Faktorial (RAL) dengan 3 perlakuaan dan 3 kali ulangan. Pemberian pakan sebesar 3 %, 5 % dan 7 % pada setiap perlakuan berupa berdasarkan berat bobot tubuh ikan uji. Benih uji ditempatkan di dalam wadah berisi 40 liter air dengan padat tebar benih untuk masing-masing wadah adalah 5 ekor dengan lama pemeliharaan 30 hari. Frekuensi pemberian pakan dilakukan sebanyak 3 kali sehari yaitu pada pukul 08.00 WIB pagi, 13.00 WIB siang dan 17.00 WIB sore. Hasil yang didapat menunjukkan bahwa perlakuan pemberian pakan tidak berpengaruh nyata terhadap pertumbuhan dan kelangsungan hidup ikan nila tersebut. Sedangkan untuk perilaku konsumsi meningkat sebesar 3 % baik pada ikan nila gift dan ikan nila merah.This study aimed to investigate the effect of different daily feed intake on growth and survival of two strains of tilapia. The study was conducted on October 18th - November 17th 2012 housed in the Laboratory of Hatchery and Technology Aquaculture, University of Malikussaleh Cunda, Lhokseumawe. Test fish used is seed of Tilapia gift and red tilapia measuring 7-8 cm. Methods used in this study was Completely Randomized Design (CRD) factorial with 3 treatments and 3 replications. The difference in feeding on each treatment A, B and C respectively 3%, 5% and 7% of the weight of biomass. Seeds of fish was put in a container maintenance with 40 liters of water volume and density of 5 tails per container for 30 days. Frequency of feeding was 3 times a day at 08.00 am, 13.00 pm and 17.00 pm. The results showed that the different feeding treatments did not significantly affect the growth and survival of two strains of tilapia and daily feed consumption growth 3% for both tilapia gift and red tilapia.

Abstract

Tingginya biaya produksi akibat dari mahalnya harga pakan berprotein tinggi menyebabkan eksplorasi bahan pakan alternatif yang bernutrisi, murah dan tersedia sepanjang tahun terus dilakukan. Penelusuran bahan alternatif ini juga diharapkan dapat meningkatkan kandungan protein dari pakan komersil berprotein rendah yang murah. Metode penelitian terdiri atas tahap pembuatan pakan uji, analisis proksimat, dan uji ketahanan pakan di air. Adapun perlakuan dalam penelitian ini adalah: (A) kombinasi ampas tahu 80% + pelet 20%, (B) kombinasi ampas tahu 60% + Pelet 40%, (C) kombinasi ampas tahu 40% + pelet 60%, (D) kombinasi ampas tahu 20% + pelet 80%, (E) kontrol (penggunaan pelet 100%). Hasil penelitian menunjukkan bahwa pakan ampel dengan kombinasi ampas tahu 40% + pelet 60% memiliki karakteristik nutrisi paling baik terutama protein sebesar 28,92%. Karakteristik fisik pakan terbaik melalui uji ketahanan pakan di air ditunjukkan oleh pakan pelet.Increment of aquaculture production cost caused by expensive feed containing high protein has made exploration of feed stuffs having high nutrition, low cost, and annually available continuously to be done. Investigation of alternative stuffs was expected to increase protein content of cheap commercial feed containing low protein. The methods of this research consisted of producing experimental feed, proximate analysis, and feed stability test in the water. The treatments were (A) combination of tofu waste 80% + feed 20%, (B) combination of tofu waste 60% + feed 40%, (C) combination of tofu waste 40% + feed 60%, (D) combination of tofu waste 20% + feed 80%, (E) control (feed 100%). This research resulted the best nutrition characteristic obtained from combination of tofu waste 40% + feed 60% in which its protein was 28,92%. The best physical characteristic through feed stability test in the water was obtained from commercial feed (control).

Abstract

Pakan merupakan bagian utama dalam menunjang keberhasilan kegiatan budidaya yang dilakukan. Dengan demikian, diperlukan kajian yang intensif untuk mencari formulasi yang tepat agar tujuan tersebut dapat tercapai secara optimal. Penelitian ini dilakukan untuk menguji persentase yang optimal antara ampas tahu dengan pelet untuk meningkatkan pertumbuhan ikan lele sangkuriang dan menekan biaya pakan seminimal mungkin. Metode analisa data yang digunakan berupa rancangan acak kelompok non-faktorial dengan 5 (lima) perlakuan dan 3 (tiga) kali ulangan, selanjutnya data dianalisis dengan uji F. Perlakuan tersebut berupa: 1) Pakan A: Ampas tahu 80% + pelet 20%; 2) Pakan B: Ampas tahu 60% + pelet 40%; 3) Pakan C: Ampas tahu 40% + pelet 60%; 4) Pakan D: Ampas tahu 20% + pelet 80%; dan 5) Pakan E: Pelet 100% (kontrol). Parameter penelitian meliputi efisiensi pakan, laju pertumbuhan ikan, dan kelangsungan hidup. Hasil penelitian menunjukkan bahwa nilai efisiensi pakan terbaik pada pakan kontrol (pelet) sebesar 77,61%, laju pertumbuhan harian ikan lele sangkuriang yang terbaik diperoleh dari pakan pelet (kontrol) sebesar 3,64%. Sementara untuk kelangsungan hidup yang terbaik didapat pada perlakuan pakan B dan C yaitu sebesar 100%.Feed is a major part in the success of farming activities undertaken. Thus, the necessary intensive study to find the right formulation so that these objectives can be achieved optimally. This study was conducted to test the optimal percentage of tofu by product (TbP) with the pellets to increase fish growth and suppress catfish feed costs to a minimum. Data analysis method used in the form of non-factorial randomized design with 5 (five) treatments and 3 (three) replications, then the data were analyzed by F test. These treatments include: 1) Feed A: TbP 80% + 20% pellets; 2) Feed B: TbP 60% + 40% pellets; 3) Feed C: TbP 40% + 60% pellets; 4) Feed D: TbP 20% + 80% pellets; and 5) Feed E: Pellet 100% (control). Parameter research include feed efficiency, growth rate of fish, and survival. The results showed that the best feed efficiency in the control diet (pellets) amounted to 77.61%, daily growth rate of fish catfish are best obtained from feed pellets (control) of 3.64%. While survival is best obtained at treatment of feed B and C equal to 100%.
