Aeromonas hyrophila strains AHV1, AHV2 and AH3 were isolated and identified from Muscle tissue, intestine, body fluid and gills of infected gold fish Carassius auratus. In order to study their virulence, LD50 tests against  normal gold fish, proteolytic, haemolytic and challenge studies were performed. The virulence studies revealed that, both AHV1 and AHV2 strains are highly positive for proteolytic and haemolytic properties. The LD50 data showed that, the fish C. auratus are highly susceptible to A. hyrophila strains AHV1 and AHV2 at cent percent lethal rate. The survival of C. auratus significantly (P<0.05) decreased when challenged with virulent strains of A. hydrophila AHV1 and AHV2. The outer membrane protein (OMP-TS) gene was successfully amplified generating an the amplicon size of 1008 bp. The amplified product from the genomic DNA of AHV1 strain was cloned in to pTZ57R/T vector, transformed into DH5? cells and sequenced. The sequenced clone is resembling to various A. hydrophila isolates and submitted to NCBI GenBank database (accession no:HQ331525).

AbstrakIkan maskoki (Carassius auratus) merupakan ikan hias air tawar yang banyak ditemukan di Indonesia salah satunya daerah Jawa Timur. Ikan maskoki merupakan hasil persilangan ikan mas yang banyak dikembangkan di Negara Jepang maupun Cina. Ikan Maskoki memiliki beberapa keunggulan diantaranya dapat dijadikan ikan hias yang jinak, dan memiliki warna yang indah dan bentuk tubuh unik. Meskipun demikian, ikan hias umumnya cukup rawan terserang penyakit. Salah satu penyakit yang berbahaya bagi kegiatan budidaya ikan hias maskoki adalah fungi. Definisi penyakit ialah suatu keadaan atau sakit yang disebabkan oleh organisme patogen, yaitu parasit, virus, bakteri, dan fungi. Penelitian ini bertujuan untuk mengidentifikasi jenis fungi yang menginfeksi ikan Maskoki di Bursa Ikan Hias Gunung Sari Surabaya, Jawa Timur. Metode penelitian ini adalah survei. Parameter utama yang diamati dalam penelitian ini adalah jenis fungi yang menginfeksi ikan maskoki di Bursa Ikan Hias Gunung Sari Surabaya, Jawa Timur. Sedangkan sebagai parameter temperatur, amonia, dan oksigen terlarut yang diukur selama kegiatan sampling.Hasil penelitian menunjukkan dari 25 sampel ikan yang diambil dari 6 lokasi, 11 ekor ikan positif terinfeksi fungi. Fungi tersebut adalah Aspergillus flavus, Aspergillus niger, Penicillium glabrum, Saprolegnia. Perlu dilakukan penelitian mengenai tingkat patogenitas dari masing-masing spesies fungi sehingga diperoleh data yang dapat digunakan untuk melakukan pencegahan. Abstract The goldfish (Carassius auratus) is one of ornamental freshwater fish in Indonesia, especially in the East Java. The goldfish is produced by crossbreeding that has a long history in Japan and China. The goldfish is benign fish and it has beauty color and unique body. The fungi are one of the problems in fish culture. Prior research has observed, parasite, virus, bacteria, and fungi are the organism pathogen which can spread the diseases that could be founded in goldfish. The purpose of this research to identify the species of fungi that infected the goldfish in fish market Gunung Sari, Surabaya, East Java. The survey method was usee in this research. The parameters observed were fungi that infected the goldfish in fish market Gunung Sari, Surabaya, East Java. The temperature, ammonia and dissolved oxygen of water where the sample was taken were noted. The results showed that among 25 of goldfish samples from 6 different location, 11 samples were positively infected by fungi. The fungi then were identified as Aspergillus flavus, Aspergillus niger, Penicillium galbrum, and Saprolegnia based on colony and microscopic morphological observation. The pathogenecity of the fungi founded in goldfish of Gunung Sari, Surabaya, should be check to provide data for prevention purpose.

The study was conducted to compare the effect of three different fry rearing systems such as: hapa, cistern and pond on the growth and survival of goldfish (Carassius auratus ) fry. A total of 645 fry (mean initial weight: 0.0071 mg) were randomly distributed in the three treatments (systems) each having three replications. The stocking density was same in all the treatments with respect to the water volume of the systems which was 10 fry/hapa, 125 fry/cistern and 80 fry/pond. The trial lasted for 40 days. The water quality parameters were favorable in all the treatments during the period of the study. The growth and survival of goldfish fry varied among the systems. Highest average weight gain and specific growth rate (SGR) were observed in pond followed by hapa and cistern. On the other hand, survival rate was highest in cistern followed by hapa and pond. It can be concluded from the study that the pond was the best system in terms of growth rate and cistern was the best system for survival of gold fish fry.Res. Agric., Livest.
