Identifikasi Dan Prevalensi Endoparasit Pada Usus Ikan Bawal Air Tawar (Colossoma Macropomum) Kolam Budidaya Di Desa Nya, Kecamatan Simpang Tiga, Kabupaten Aceh Besar

The Purpose of this study were to identify the type of endoparasite and to find out the prevalance of endoparasite infected digestive tract of Colossoma macropomum. The study was conducted at parasitology Laboratory of Veterinary Medicine Faculty, Syiah Kuala University in May - June 2015. The sample used were collected randomly. As many as 10% of total fish in a population. The exa mination of endoparasite were carried out using smear method. Parameter measured were prevalence and physic – chemical of water. The results showed that type of endoparasite found in digestive tract of Colossoma macropomum fish was Capillaria sp. with the prevalence of 15%. Tujuan penelitian ini untuk mengidentifikasi jenis endoparasit yang menginfeksi dan mengetahui prevalensi endoparasit yang menginfeksi saluran pencernaan ikan bawal air tawar. Penelitian dilakukan di Laboratorium Parasitologi Fakultas Kedokteran Hewan, Universitas Syiah Kuala pada Bulan Mei dan Juni 2015. Penelitian menggunakan metode smear method dan penyamplingan sampel dilakukan secara acak. Sampel yang digunakan dalam penelitian sebanyak 10% dari total ikan dalam satu populasi. Parameter yang diukur yaitu prevalensi dan parameter fisika – kimia air. Hasil dari penelitian menunjukkan bahwa jenis endoparasit yang teridentifikasi pada ikan bawal air tawar adalah Capillaria sp. Nilai prevalensi yang diperoleh sebesar 15%

Pertumbuhan Benih Ikan Bawal Air Tawar (Colossoma Macropomum) pada Pemberian Pakan Alami yang Berbeda

The objective of this research was to determine the effect of life feeds on the growth performance of pomfret (Colossoa macropomum) Â larvae. Five life feed i.e. Pomacea canaliculata, Mysis relicta, Tubifex sp, Culex sp., and Daphnia sp. Were tested in this study. The research was conducted at the Laboratory of Aquatic, Veterinarary Faculty, Syiah Kuala University from April to May 2015. The completely randomized design wwith five treatments and four replications were used. The results showed that the life feeds has not gave the significant effect on the growth performance and the survival rate of C. macropomum juvenile. However, the higher growth and survival rates were found at fish fed on silk worm.Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan alami, Pomacea canaliculata, Mysis relicta, Tubifex sp, Culex sp, dan Daphnia sp terhadap pertumbuhan dan tingkat kelangsungan hidup benih ikan bawal air tawar (Colossoma macropomum). Penelitian dilaksanakan di Laboratorium Aquatik, Fakultas Kedokteran hewan Universitas Syiah Kuala, pada tanggal 15 April hingga 16 Mei 2015. Penelitian ini menggunakan Rancangan Acak Lengkap dengan lima perlakuan dan empat ulangan. Perlakuan terdiri dari Pomacea canaliculata (A), Mysis relicta (B), Tubifex sp. (C), Culex sp (D). dan Daphnia sp. (E). Hasil penelitian menunjukkan bahwa perlakuan pemberian pakan alami yang berbeda tidak berpegaruh nyata terhadap pertumbuhan dan kelangsungan hidup benih ikan bawal air tawar (C. macropomum). Namun demikian, pertumbuhan dan kelangsungan hidup yang lebih baik ditemukan pada pemberian cacing sutr

Growth performance and feed utilization of keureling (Tor tambra) fingerlings fed a formulated diet with different doses of vitamin E (alpha-tocopherol)

The objective of the present study was to determine the optimum dosage of vitamin E (alpha-tocopherol) in the diet of keureling, Tor tambra (Val.) fingerlings for optimal growth performance and feed utilization. Five doses of vitamin E were tested: 0 mg kg−1 feed (control); 150 mg kg−1 feed; 300 mg kg−1 feed; 450 mg kg−1 feed; 600 mg kg−1. The feed ratio was 5% body weight, which was delivered twice daily at 08:00 and 17:00 for 60 days. The results showed that higher growth performance, feeding conversion ratios, feed efficiency, protein retention, and protein digestibility were obtained at 600 mg kg−1 feed, but the value was not significantly different from the other doses. The optimal dose in terms of the hepatosomatic index and survival rate was 300 mg kg−1. Hence, it was concluded that the optimum, most economical dose of vitamin E supplement for keureling (T. tambra) was 150 mg kg−1 feed, because this value was not significantly different from the doses of 300 and 600 mg kg−1 feed
