Published: February 2017

Penelitian terhadap komposisi dan distribusi ikan petek (Leiognathidae) di perairan SelatMakassar (perairan timur Kalimantan), dilakukan pada bulan Juni sampai dengan Juli 2005 dengan menggunakan KM. Bawal Putih. Hasil penelitianmenunjukkan bahwa hasil tangkapan ikan petek (Leiognathidae)merupakan ikan dominan yang ke-2 dengan persentase 17,43%. Pada penelitian ini diperoleh 12 jenis ikan petek (Leiognathidae), dengan 3 genus yaitu Leognathus (7 spesies), Secutor (3 spesies), dan Gaza (2 spesies). Di antara ikan petek yang tertangkap, Leiognathus bindus mempunyai laju tangkap paling tinggi yaitu 12,53 kg per jam, dengan ukuran dominan antara FL 6,5 sampai dengan 7,0 cm, sedangkan Leiognathus splendens merupakan urutan ke-2 dengan laju tangkap 6,66 kg per jam, dengan ukuran dominan antara FL 10,0 sampai dengan 10,5 cm. Distribusi secara vertikal menunjukkan bahwa ikan petek, dominan tertangkap pada kedalaman perairan 21 sampai dengan 30 m, yang berlaku untuk semua jenis atau spesies ikan petek (Leiognathidae). Sedangkan distribusi horisontal ikan petek, dominan tertangkap di sekitar perairan Nunukan dan Tarakan. Research on catch composition, distribution, and some biological aspects of pony fish was conducted in June to July, 2005th using RV. Bawal Putih in the waters of East Kalimantan. Results show that the pony fish (Leiognathidae) provides the second largest component in the catch (17.43%), after Ariidae (30.02%). There were 3 genera of Leiognathidae i.e. Leiognathus (7 species), Secutor (3 species), and Gaza (2 species). Leioghnatus bindus was the highest catch rate within the Leioghnatidae group amoung to about 12.5 kg per hr, with the dominant size of FL 6.5 to 7.0 cm group, followed by Leioghnatus splendens with the catch rate of 6.75 kg per hr and the size of 10.0 to 10.5 cm. Based on depth distribution data it’s likely that the pony fish group was dominantly in the depth range of 21 to 30 m. Based on horizontal distribution data the pony fish group was dominantly in the East-Tarakan waters (1°49’ N–3°55’ N dan 117°53’ E–118° 31’ E).

ABSTRACT Koi herpesvirus (KHV) is a major viral pathogen that infects common carp and koi. KHV disease outbreak is happened in almost all centre of common carp culture in Indonesia and caused mass mortality. Deoxyribonucleic acid (DNA) vaccination method is one of ways to cope with KHV infection. Vaccines were commonly given by injection. The aim of this research was to get frequency and persistency of DNA vaccine encoding GP25 given by oral delivery method in common carp. This research would like to determine dose, frequency of vaccination, persistency of DNA vaccine and culture medium for the bacterial host. DNA vaccine persistency test was done by using polymerase chain reaction (PCR) method with the specific primer for GP25 gene. The results showed that level of DNA vaccine that could be detected in feed was 7.56 ng (equal to 1.598×1010 copies). Efficient culture medium for Escherichia coli DH5α carrying DNA vaccine was LB triptone. Feeding fish with diet supplemented with 1 mL E. coli DH5α containing DNA vaccine for each fish and two times a week allowed persistence of DNA vaccine in kindney and spleen. Keywords: common carp, KHV, DNA vaccine, GP25, persistance ABSTRAK Koi herpesvirus (KHV) adalah virus patogen utama yang menginfeksi ikan mas dan ikan koi.

ABSTRACT Sludge worm (Tubifex sp.) as natural feed on catfish (Pangasionodon sp.) larvae rearing is available in limited amount especially during rainy season. It becomes a constraint factor for larvae rearing sector. This research was conducted to evaluate the appropriate initial age of catfish larvae to get artificial feed as sludge worm replacement. Evaluation was conducted on the growth and survival of catfish larvae in 14 days of culture. There were four treatments of feeding in triplicates i.e. larvae were given natural feed without artificial feed, given artificial feed started from d3, d6, and d9) with three replications. The results showed that larvae fed on artificial feed on d3 had the lowest growth compared to the other treatments, whereas the survival was not significantly different (P>0.05) among the treatments. As a conclusion, artificial feed could be used to replace natural feed for catfish larvae started at the age of nine days. Keywords: sludge worm, catfish larvae, artificial feed ABSTRAK Cacing sutra (Tubifex sp.) tersedia dalam jumlah terbatas terutama pada musim penghujan sebagai pakan alami dalam usaha pembenihan ikan patin (Pangasionodon sp.).
