Abstract

Untuk mengetahui respons kelangsungan hidup lele terhadap berbagai metoda pengangkutan telah dilakukan penelitian dengan menggunakan ikan lele dumbo sangkuriang ukuran panjang tubuh 5 sampai 7 cm. Penelitian ini menggunakan rancangan acak lengkap dengan 4 perlakuan, yaitu (l) Pengangkutan terbuka dengan wadah ember; (2) Pengangkutan tertutup tanpa penambahan oksigen murni maupun es batu; (3) Pengangkutan tertutup dengan penambahan oksigen murni; (4) Pengangkutan tertutup dengan penambahan oksigen murni dan es batu. Variabel yang diukur meliputi angka kelangsungan hidup, suhu air media dan kadar glukosa darah yang digunakan untuk mengukur perubahan laju metabolisme. Data yang diperoleh dianalisis secara deskriptif. Data kelangsungan hidup ikan yang ditransportasi dengan berbagai metode rnenunjukkan perbedaan yang signifikan, yaitu dari 0% hingga 100 %. Angka kelangsungan hidup ikan lele dumbo "Sangkuriang" pada metode pengangkutan terbuka, metode pengangkutan tertutup tanpa oksigen dan tanpa es batu, metode tertutup dengan oksigen murni, serta metode tertutup dengan oksigen murni dan es batu masing-masing adalah 98% ,0%,98%, dan 100%. Metode pengangkutan tertutup tanpa oksigen maupun es batu memperlihatkan kenaikan nilai suhu air media terbesar, yaitu dari 26oC menjadi 28,1oC. Perubahan suhu selama pengangkutan berdampak terhadap aktivitas katabolisme glukosa yang diindikasikan adanya perubahan kadar glukosa dalam darah. Pengangkutan ikan sistem tertutup dengan penambahan oksigen murni dan es batu memberikan hasil angka kelulushidupan terbaik, yaitu 100%. Kata Kunci: lele sangkuriang, transportasi, kelangsungan hidup, suhu, glukosa darah To determine the survival responses of catfish on the various method of transportation systems, it has been studied by using African catfish "sanglatriang" with its body length varried between 5 to 7 cm. This study used a completely randomized design with four treatments, namely (l) open transportation containers; (2) closed transportatian without the addition of oxygen and ice; (3) closed transportatian with the addition of oxygen, and (4) closed transportation with the addition oxygen and ice. The variables measured included survival rate, water temperature,and blood glucose levels (to examine the changes in metabolic rate). The data obtained were analyzed descriptively. Results on the survival of fish that were transported by variaus methods showed signiJicantly differences, i.e., ranged from 0 to 100%,. The survival rate of African catfish "Sangkttriang" on the open method of transportation system, closed transportation method system without oxygen and without ice, closed transportation method system with oxygen, as well as closed methods with oxygen and ice are 98%, 0%, 98%, and 100%, respectively. Method of transportatin system without oxygen and ice showed the largest increasing in water temperature, i.e, from 26 to 28.1oC. The changes of temperature during transportation affect the activity of glucose catabolism indicated a change in blood glucose levels. Transporting fish in closed system with the addition of oxygen and ice resulted the best survival rate value, i.e. 100%. Keywords: catfish 'sangkuriang', transportation system, survival rate, temperatur, blood glucose
