Abstract

Silver pompano fish is a prospective commodity that can be cultured and contains high economic value. Due to its high economic value nationally and internationally, it is important to develop nursery business. The silver pompano fish nursery conducted in a pond become efficient because it can be easily controlled. The purpose of the study was to know the technology and growth of silver pompano fish fry in cages at a pond. Research activities were carried out in the hafa size (3x3x1m3) in ponds. The seeds were taken  from hatchery with size of 5.0-6.0  cm. Stocking density of seeds  were 50 pc/ m³. The nursery were reared  for 90 days till the fry reached their size in between   15.0 and 18.0 cm. The commercial  pellets with protein content of 28-30% with dose of 5-8% of body weight were provided in the morning and afternoon at satiation. Sampling of fry was conducted every 30 days, to measure the survival rate (SR), total length (TL) and body weight (BW). Data were processed with descriptive analysis. The results showed that the survival rate was 90.20 ± 2.60 %, total length was  16.80± 2.70 cm, and body weight was  145.20 ± 2.70 g. The diversity of fry has four size categories i.e., large (L), medium (M), small (S), and super small (SS) with percentage average of 17.50%, 52.70%, 20.70% and 9.10%, respectively. Keywords: net cage, pond, silver pompano fish, growth, survival

Abstract

Ikan bandeng, Chanos chanos merupakan salah satu ikan ekonomis penting di Asia. Sejak tahun 1995, di Indonesia sebagian besar benih bandeng diproduksi dari hatchery sekitar Dusun Gondol, Bali Utara baik untuk pasar domestik maupun perdagangan internasional. Dalam rangka meningkatkan kualitas benih, perlu dilakukan perbaikan induk secara genetik menggunakan populasi yang unggul. Tujuan penelitian ini adalah mendapatkan data laju pertumbuhan dan variasi genetik induk ikan bandeng yang berasal dari lokasi perairan Aceh, Bali, dan Gorontalo. Pertumbuhan ikan bandeng diamati melalui pengukuran panjang dan bobot benih hingga ukuran 500 g (calon induk), serta variasi genetik diamati menggunakan metode RFLP DNA. Benih dan calon induk masing-masing dianalisis sebanyak 15 ekor. Hasil pengamatan pertumbuhan ikan bandeng mulai dari benih hingga menjadi calon induk, menunjukkan bahwa ikan bandeng dari Aceh dan Bali mempunyai pertumbuhan panjang dan bobot yang relatif lebih tinggi dibandingkan dengan ikan bandeng dari Gorontalo, walaupun secara statistik tidak berbeda nyata (P<0,05). Hasil analisis variasi genetik terdapat lima komposit haplotipe dari empat enzim restriksi yaitu Mbo I, Hae III, Hha I, dan Nla IV pada sekuens cytochrome-b. Jumlah rata-rata restriction site adalah 1-3 haplotipe. Populasi Aceh dan Bali memiliki nilai keragaman genetik yang lebih rendah (0,080 dan 0,000) dibandingkan dengan calon induk dari benih Gorontalo (0,115).Milkfish, Chanos chanos is one of the economically important fish in Asia. Since 1995, milkfish seed mostly produced in Gondol area, Northern part of Bali, and suppleted both domestic and international markets. In order to improve its seed quality the improvement of milkfish broodstock genetic is required through selection of superior population. The aims of this research were to evaluate the growth performance and genetic variation of milkfish populations from Aceh, Bali, and Gorontalo Province. The length and weight of fry up to 500 g was measured as well as the genetic variation was detected using RFLP DNA method. Fry and young broodstock in the DNA analyses were 15 individuals. The results showed that the growth in length and weight milkfish seed from fry to young broodstock (size up to 500 g) from Aceh and Bali was slightly higher than that of Gorontalo, but no significant differences (P>0.05) were observed among the populations. The genetic analysis showed five haplotypes composite from four restriction enzymes i.e., Mbo I, Hae III, Hha I, and Nla IV at on cytochrome-b sequen. The average number of restriction site was 1-3 haplotypes. Aceh and Bali populations have lower genetic variations (0.080 and 0.000) compared to Gorontalo (0.115).

Abstract

The natural stock of sea cucumber Holothuria scabra (known as sandfish) has been declining in both population and size, making it difficult to collect broodstock and juvenile sandfishes for aquaculture. This research aims to evaluate the reproduction of domesticated broodstock (F-1) and performance of the juveniles (F-2). Broodstock were reared in two rectangular concrete tanks with a dimension of 190 x 290 x 70 cm3. There were 12 individuals (7 males and 5 females) of broodstock (F-1) with total length and mean body weight of 12.0 ± 1.21 cm and 122.6 ± 32.37 g, respectively. Six broodstock were put in each tank and fed with compressed benthos at 4% biomass daily in the afternoon. During our experiment, domesticated sandfish broodstock successfully spawned twice. The first spawning (occurred in January 2017) had one female spawned that released 1,350,000 eggs with a hatching rate of 57.4%. Another broodstock spawned in April 2017 and produced 3,280,000 eggs with a hatching rate of 78.66%. The growth performance of 170 days-old juveniles (F-2) shows a total length of 5.66 ± 0.90 cm and a mean body weight of 10.08 ± 2.07 g. The survival rates are 5.19% and 8.68% for juveniles spawned in January and April, respectively. We conclude by showing that sandfish could be domesticated to produce seeds for further aquaculture development.

Abstract

Piscine nodavirus sebagai penyebab penyakit VNN (Viral Nervous Necrosis) dan iridovirus merupakan jenis virus yang dikenal menjadi penyebab utama kematian ikan laut yang dibudidayakan. Virus ini mampu menginfeksi ikan dari ukuran benih sampai ukuran konsumsi dan dalam waktu dua minggu, kematian mencapai 80% sampai 100%. Pada pembenihan larva dan benih ikan dalam skala rumah tangga ataupun hatcheri lengkap di sepanjang pantai di wilayah Bali Utara sering mengalami infeksi VNN dan iridovirus Namun, informasi terjadinya infeksi belum didata dengan baik. Tujuan penelitian ini untuk memperoleh data dan informasi mengenai peta infeksi atau serangan virus pada pembudidaya/pembenihan ikan sepanjang tahun 2017 di Bali Utara. Sampling dilakukan pada bulan Februari, Mei, Agustus, dan Oktober. Di samping melakukan sampling, juga dilakukan input data dari hasil analisis sampel di laboratorium bioteknologi yang diperoleh dari pemilik hatcheri/pembudidaya ikan. Analisis VNN menggunakan metode IQPlus sedangkan analisis iridovirus dengan metode PCR konvensional dengan primer spesifik. Parameter yang diamati adalah prevalensi VNN dan iridovirus dari setiap hatcheri dan keramba jaring apung. Sebagai data penunjang pengukuran parameter kualitas air berupa suhu, salinitas, amoniak, dan nitrit yang dilakukan pada saat pengambilan sampel benih. Hasil penelitian menunjukkan bahwa tingkat infeksi VNN di hatcheri Bali utara terjadi di bulan September sebesar 33,3% dan iridovirus pada bulan Agustus mencapai 18,61%. Sedangkan tingkat prevalensi VNN tertinggi di KJA terjadi pada bulan Oktober mencapai 83,4% dan puncak infeksi iridovirus terjadi di bulan Februari dengan nilai prevalensi sebesar 50,0%.VNN and iridovirus are viral diseases causing the highest mortality in mariculture. These viruses are able to infect eggs, larvae, juveniles and even marketable size fish. They can cause 80% to 100% mortality in just two weeks. Larvae or fingerlings in small or big scale hatcheries in Northern Bali were frequently infected by VNN or Iridovirus. Unfortunately, information about the local disease outbreaks was not well documented. The aim of this research was to collect data and information about the infection of these viruses in hatcheries and floating net cage mariculture in Northern Bali during 2017. Sampling was conducted in February, May, August, and October, 2017. In addition to the primary data from the field activities, disease infection secondary dataset from the fish farmers who analyzed their infected fish in our laboratory were also used. The identification of VNN infection was performed following IQPlus method while Iridovirus was tested using the conventional PCR method with specific primers. The parameters observed were the VNN and Iridovirus prevalence in each hatchery and floating net cage. Water quality parameters were measured in situ such as temperature, salinity, ammonia, and nitrite. The results showed that infection of VNN in hatcheries at Northern Bali, the highest infection was found in September as high as 33.3% and Iridovirus in August at 18.61%. While in Floating Net Cage the highest infection for VNN was found in October with value of 83.4% and Iridovirus was found in February with value of 50.0%.
