Abstract

The objective of the present study was to determine the optimum dosage of papain enzyme for snakehead fish (Channa striata). The study was done at the laboratory of veterinary medicine, Faculty of Veterinary Medicine, Syiah Kuala University from January to March 2016. The complete random design method was utilized in this study and seven levels of papain dosages were tested in this study namely; 0.0%/kg, 0.5%/kg, 1.0%/kg, 1.5%/kg, 2.0%/kg, 2.5%/kg, dan 3.0%/kg of feed.  The experimental fish were fed on an experimental diet two times a day on 8 AM and 5 PM at feeding level at 5% body weight for 70 days. The results showed that the absolute growth rate of the weight gain ranged between 1.50 g and 3.24 g, daily growth rate between 0.02 g per day to 0.04 g per day, the specific growth rate ranged from 1.75% per day to 2.42% per day, survival rate reached 100%, feed conversion ratio ranged from 1.93 to 2.39, feed efficiency ranged between 41.96% and 51.67%, protein retention ranged between 15.14% and 30.72% and protein digestion ranged from 47.51% to 84.62%. The Anova test showed that enzyme papain gave the significant effect on the absolute weight gain, daily growth rate, specific growth rate, feed conversion ratio, feed efficiency, protein retention, and protein digestion (P<0.05), but did not give the significant effect on survival rate (P>0.05). Therefore, it is concluded that the optimum lead level of papain in the diet of snakehead fish is 3.0 %/kg of feed.Penelitian ini bertujuan untuk mengetahui dosis enzim papain yang optimal dalam pakan buatan, terhadap tingkat pemanfaatan protein dalam pakan dan laju pertumbuhan ikan gabus (Channa striata). Penelitian ini dilaksanakan di Laboratorium Akuatik Fakultas Kedokteran Hewan Universitas Syiah Kuala pada bulan Januari sampai Maret 2016. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL). Faktor yang diuji perbedaan dosis enzim papain; 0,0%/kg, 0,5%/kg, 1,0%/kg, 1,5%/kg, 2,0%/kg, 2,5%/kg, dan 3,0%/kg. Pakan diberikan 2 kali sehari 5% dari bobot tubuh (08.00 dan 17.00 WIB) selama 70 hari. Hasil uji ANOVA menunjukkan bahwa enzim papain berpengaruh nyata terhadap pertumbuhan bobot mutlak, laju pertumbuhan harian, laju pertumbuhan spesifik, rasio konversi pakan, efisiensi pakan, retensi protein dan ketercernaan protein (P<0,05), tetapi tidak berpengaruh nyata terhadap tingkat kelangsungan hidup benih ikan gabus (P>0,05). Hasil penelitian diperoleh nilai pertumbuhan bobot mutlak berkisar antara 1,50 g – 3,24 g, laju pertumbuhan harian berkisar antara 0,02 g perhari – 0,04 g perhari, laju pertumbuhan spesifik berkisar antara 1,75 % perhari – 2,42 % perhari, tingkat kelangsungan hidup 100%, rasio konversi pakan berkisar antara 1,93 – 2,39, efisiensi pakan berkisar antara 41,96 % - 51,67 %, retensi protein berkisar antara 15,14 % - 30,72 % dan ketercernaan protein berkisar antara 47,51 % - 84,62 %. Oleh karena itu dapat disimpulkan dosis enzim papain yang terbaik untuk ikan gabus adalah 3,0%/kg pakan.

Abstract

The existence of fish aggregating devices (FADs) in a waters is able to establish a new fishing ground that potential waters. FADs are able to attract the attention of the gathering of fishes and other aquayic organisms around it, increasing the density of fish around FADs can increase the chances of successful catching operation, and therefore the FADs has benefited significantly to increase the capture fishery production significantly. The purposes of the research were to evaluate the catching composition of purse seine production  using FADs and non FADs, and to examine the fectiveness of FADs. This research was conducted on February 1 - 28, 2018 located at Pusong Waters, Lhokseumawe City. The survey  method was used in this study. The direct sampling by following the fisherman in fishing activities was performed both the purse seine with FADs and no FADs. Total purse seine catches during the research were 4,320 kg consisting of Long Jawed Mackerel (Rastrelliger sp.) 1,280 kg (29.63%), Decapterus Fish ( Decapterus sp.) 350 kg (8,107%), skipjack tuna (Katsuwonus pelamis) 845 kg (19.56 %), tuna fish (Euthynnus affinis) 720 kg (16.67%), Torpedo scad (Megalaspis cordyla) 300 kg (6.94%), Queenfish 140 kg (3.24%), and starry triggerfish (Abalistes stellaris) 685 kg (15.86%). It was concluded that the purse seine used FADs is more effective  compared to the a purse seine that does not use FADs.Keberadaan rumpon di suatu perairan mampu menarik perhatian berkumpulnya ikan dan organisme lain disekitarnya, sehingga dapat meningkatkan hasil tangkapan ikan.

Abstract

The objective of present study was to determine the optimum level of papain in the diet of keureling fish (Tor tambra). The complete random design was utilized in this study. Six levels of papain dosage were tested in triplicates, i.e. 0 (control); 17.5 mg kg-1, 20.0 mg kg-1, 22.5 mg kg-1, 25.0 mg kg-1 and 27.5 mg kg-1 of feed. The experimental fish were fed the experimental diet two times a day at 8 AM and 5 PM at feeding level of 5% body weight for 90 days. The Anova test result showed that papain enzyme gave a significant effect on the weight gain, daily growth rate, specific growth rate, survival rate, feed conversion ratio and feed efficiency (P<0.05). The Duncan multi-rage test result showed that the higher values for all measured parameters were obtained at the dosage of 27.5 mg kg-1. Therefore, it is concluded that the optimum dosage of papain enzyme for keureling fish was 27.5 mg kg-1 of feed.How to CiteMuchlisin, Z. A., Afrido, F., Murda, T., Fadli, N., Muhammadar, A.

Abstract

The objective of the present study was to evaluate the migration time of glass eels (Anguilla spp.)  in the estuary of  Lambeuso River, Aceh Jaya District, Indonesia. The survey was done in March and June 2015.  The sampling location was determined based on an initial survey during February 2015 by considering the river condition. Based on initial survey there are no glass eels were recorded during noon time, and therefore the sampling was focused at night. The sampling was done four times a month (weekly basis) for three months (12 times in total) using trap nets based on Hijri Calendar. The trap was settled up to opposite direction of tide (seaward) from 18.00 PM to 06.00 AM  and the catches glass eels were monitoring one-hour interval.  A total of 131 glass eels were sampled during the study, where the samples were only caught on first (new month) and fourth week (old month) base on Hijri Calender  during spring tide and  no glass eels were sampled during second and third weeks. It was concluded that the migration time of the glass eels (Anguilla spp.) in Lambeso Rivers is during the dark moon at the new and old month of Hijri Calendar
