Abstract

The silver arawana Osteoglossum bicirrhosum (Cuvier, 1829) has been cultured successfully in Indonesia, but still facing obstacles especially handling on the larval life stage. Yolk-sac stage is one of the critical phases in the early development of fish. Yolk-sac larvae of silver arawana use a yolk as food supply. The yolk absorption process influenced by abiotic factors, particularly temperature and salinity. Hence, this study aimed to examine the interaction of temperature and salinity of media in order for optimal yolk-sac absorption and morphogenesis of silver arawana larvae. The research was conducted from November 2013 to January 2014 in the Laboratory of Aquatic Animal Physiology, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. The experimental design was arranged in two factors completely randomized designs, nine treatments with three replications. The first factor was the temperature consisted of 28, 30 and 32°C; the second factor was the salinity consisted of 3, 4 and 5%o. Yolk-sac larvae were reared in aquarium 40 x 30 x 30 cm3 with a density of 4 yolk-sac larvae per aquarium until the yolk was completely absorbed. Larvae were not fed during the experiment. The parameters measured were survival rate, time of yolk absorption, shrinkage rate of yolk, efficiency of yolk utilization, total length, total weight, specific weight growth rate, gradient osmotic oxygen consumption, and morphogenesis of larvae. The results showed that the silver arawana larvae reared at 28°C in combination with all levels of salinity (3, 4 and 5%o) and temperature of 30°C with a salinity of 3%o generate survival rate 100%. Meanwhile, the efficiency of yolk utilization, the fastest growth and morphogenesis were optimally at a temperature of 30°C in interaction with 3%o salinity. Abstrak Arwana silver Osteoglossum bicirrhosum (Cuvier, 1829) telah berhasil dibudidayakan di Indonesia, namun masih mengalami kendala terutama penanganan pada fase pralarva. Pralarva merupakan salah satu stadia yang rentan dalam perkembangan awal hidup ikan. Pralarva arwana silver memiliki kuning telur yang digunakan sebagai cadangan ma-kanan. Penyerapan kuning telur pralarva dipengaruhi oleh faktor abiotik terutama suhu dan salinitas. Penelitian ini ber-tujuan untuk mengkaji interaksi suhu dan salinitas media pemeliharaan agar optimal untuk penyerapan kuning telur dan morfogenesis pralarva arwana silver. Penelitian dilakukan dari bulan November 2013 hingga Januari 2014 di La-boratorium Fisiologi Hewan Air, Fakultas Perikanan dan Ilmu Kelautan, Institut Pertanian Bogor. Penelitian ini meng-gunakan rancangan acak lengkap faktorial dengan sembilan perlakuan dan masing-masing perlakuan memiliki tiga ulangan. Faktor pertama terdiri atas suhu 28, 30 dan 32°C, faktor kedua terdiri atas salinitas 3, 4 dan 5%o.

Abstract

Tilapia is one of the introduced fish species in Indonesia and was firstly imported from Taiwan in 1969. Since that time, many efforts have been made to increase its quality through genetic improvement. Some strains of tilapia have been successfully generated such as best, nirwana II, jatimbulan and sultana. In sustainable aquaculture, success of culture production depends on good environmental conditions and water quality. The aim of this study was to evaluate the phenotype performances of four strains of tilapia obtained through selective breeding reared in floating net and ponds. A completely randomized designs with two factors were used in this research, i.e. strains of tilapia and culture system with three replicates. Fifty fish with an average body length of 3-5 cm was reared in ponds and floating net 2 x 2 x 1 m, fed daily in the morning and afternoon during the experiment. Twenty fish from each strain were sampled in every two weeks and fish body length and body weight were measured. Truss morphometric measurement was conducted after 12 weeks of rearing process. The results showed that sultana strain has the highest growth rate, jatimbulan and best strains have the similar survival and feed conversion rates, while the highest biomass was found in the best strain. The nirwana II has the lowest survival rate (18%), but this strain showed the highest feed efficiency. Culture system affects the phe-noltypic variance of truss morphometric, viz. eleven characters in floating net and two characters in pond specimens. Abstrak Nila di Indonesia merupakan ikan introduksi yang didatangkan dari Taiwan pertama kali pada tahun 1969. Dalam peri-ode yang cukup lama, upaya peningkatan kualitas benih ikan dilakukan secara terus menerus melalui perbaikan mutu genetik. Beberapa strain ikan nila yang telah dihasilkan di antaranya nila best, nirwana II, jatimbulan, dan sultana. Da-lam kegiatan perikanan budi daya yang berkelanjutan, faktor lingkungan dan kualitas perairan merupakan pembatas ke-berhasilan usaha budi daya. Tujuan penelitian ini adalah untuk mengevaluasi keragaan fenotipe empat strain ikan nila hasil pemuliaan pada sistem budi daya karamba jaring apung (KJA) dan kolam air tenang. Penelitian ini dirancang menggunakan rancangan acak lengkap pola faktorial yang terdiri atas faktor empat strain ikan nila dan faktor sistem bu-di daya yaitu KJA dan kolam air tenang. Setiap perlakuan diulang tiga kali. Tiap wadah kolam dan KJA ber-ukuran 2 x 2 x 1 m3 dimasukkan benih sebanyak 50 ekor berukuran 3-5 cm, dan diberi pakan pada pagi dan sore selama masa pe-meliharaan. Setiap dua minggu dilakukan sampling masing-masing strain 20 ekor untuk pengamatan panjang dan bo-bot. Setelah 12 minggu pemeliharaan dilakukan pengukuran truss morfometrik. Hasil penelitian menunjukkan bahwa ikan nila strain sultana memiliki laju pertumbuhan tertinggi, jatimbulan memiliki tingkat kelangsungan hidup dan kon-versi pakan yang sama dengan best, biomassa tertinggi dicapai pada nila best, sementara nirwana II memiliki kelang-sungan hidup yang paling rendah (18%) namun memiliki efisiensi pakan yang terbaik. Sistem pemeliharaan memenga-ruhi peningkatan ragam fenotipe truss morfometrik yakni 11 karakter di KJA dan dua karakter di kolam air tenang.

Abstract

This study aimed to evaluate the effects of cinnamon Cinnamomum burmannii leaves extract addition with different doses in the diet for the growth performance of catfish Pangsianodon hypophthalmus. This study consisted of five treatments and three replications. The cinnamon leaves extract mixed into the diet with 5 doses i.e: 0 (control); 0.5; 1; 2; and 4 g kg-1 diet. Catfish (7.43+0.01 g) were reared in 15 aquariums (160 litres volume) with a density of 30 fishes in each aquarium for 60 days. Fishes were fed at satiation three times daily at 08.00, 12.00, 16.00 WIB. The addition of cinnamon leaves extracts in the amount of 1 g kg-1 diet showed the optimal result because this dose can improve protein retention and feed efficiency in a value at 24.6% and 23.4% with the same growth rate with the treatment without additional cinnamon leaves extract (control). Abstrak Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan ekstrak daun kayu manis Cinnamomum burmannii dengan dosis berbeda pada pakan terhadap kinerja pertumbuhan ikan patin Pangasianodon hypophthalmus. Penelitian ini terdiri atas lima perlakuan dan tiga ulangan. Ekstrak daun kayu manis dicampurkan ke dalam pakan dengan lima dosis yaitu: 0 (kontrol); 0,5; 1; 2; dan 4 g kg-1 pakan. Ikan patin (7,43+0,01 g) dipelihara dalam 15 akuarium (volume 160 liter) dengan kepadatan 30 ekor/akurium selama 60 hari. Ikan diberi pakan secara at satiation sebanyak tiga kali sehari pada pukul 08.00, 12.00 dan 16.00. Hasil penelitian menunjukkan bahwa penambahan ekstrak daun kayu manis sebanyak 1 g kg-1 pakan memberikan hasil yang optimal karena dapat meningkatkan retensi protein dan efisiensi pakan sebesar 24,6% dan 23,4% dengan laju pertumbuhan yang sama dengan perlakuan tanpa penambahan ekstrak daun kayu manis (kontrol).

Abstract

The aim of this study was to evaluate the effect of Pregnant mare serum gonadotropin (PMSG), Anti-Dopamine (AD) and Recombinant growth hormone (RGH) through the injection technique on gonadal development of eel (Anguilla bicolor bicolor). The experimental was arranged in completely randomized design with five treatments of hormone combination, namely P10A combination hormone (10 IU PmsG + 0.1 mgL-1 AD), P10B (10 IU PMSG + 0.1 mgL-1 AD + 10 ug RGH), P20A (20 IU PMSG + 0.1 mgL-1 AD), P20B (20 IU PMSG + 0.1 mgL-1 AD + 10 ug RGH), and PK (negative control). In each treatment, a total of 20 fish individuals used as replicates and the hormonal induction was conducted every week for eight weeks of the rearing period. Specific growth rate (SGR), hepatosomatic index (HSI), go-nadosomatic index (GSI) and an index of the eye (IM) were observed. The results showed that the P20A treatment increased spermatogenesis and the value of GSI (2.291±0.278%) at 4-6 weeks after injection. This result was higher than P20B (2.134±0.265%), P10B (2.065±0.201%), P10A (2.037±0.105%), and PK (1.937±0.050%). The value of HSI on the P20a treatment (1.188±0.091 %) was higher than other treatments. The highest value of SGR (0.514±0.062%) was found in the P20B, whereas the lowest value (0.052±0.027%) was found in the PK. Thus, the combination of pMsG, AD and RGH hormones can stimulate the development of testicular of eel with body weight 140 to150 g, and stimulate the growth of 0.514 % during the six-weeks rearing period. Abstrak Penelitian ini bertujuan mengevaluasi penggunaan hormon Pregnant Mare Serum Gonadotropin (PMSG), Anti Dopamin (AD) dan Recombinant Growth Hormone (rGH) melalui teknik penyuntikan terhadap pematangan gonad ikan sidat (Anguilla bicolor bicolor). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan kombinasi hormon yaitu 10 IU PMSG + 0,1 mgL-1 AD (P10A), 10 IU PMSG + 0,1 mgL-1 AD + 10 ^g rGH (P10B), 20 IU PMSG + 0,1 mgL-1 AD (P20A), 20 IU PMSG + 0,1 mgL-1 AD + 10 ^g rGH (P20B), dan PK (kontrol). Pada setiap perlakuan, sebanyak 20 ekor ikan digunakan sebagai ulangan individu dan sampling dilakukan setiap minggu selama delapan minggu masa pemeliharaan. Parameter yang diamati meliputi nilai laju pertumbuhan spesifik (LPS), indeks he-patosomatik (IHS), indeks gonadosomatik (IGS) dan indeks mata (IM). Hasil penelitian menunjukkan bahwa perlakuan P20A menyebabkan perkembangan spermatogenesis dan meningkatkan nilai IGS tertinggi (2,291±0,278%) pada minggu ke empat hingga ke enam setelah penyuntikan dibandingkan perlakuan P20B (2,134±0,265%), P10B (2,065± 0,201%), P10A (2,037±0,105%) dan PK (1,937±0,050%). Nilai IHS pada perlakuan P20A (1,188±0,091%) lebih tinggi dibandingkan dengan perlakuan lainnya. Nilai LPS tertinggi ditemukan pada perlakuan P20B (0,514±0,062 %) dan te-rendah pada perlakuan Kontrol (0,052±0,027%). Nilai IM juga meningkat pada perlakuan P20B (10,599±2,372) seiring dengan bertambahnya bobot tubuh dan terendah pada perlakuan PK (7,189±0,217). Kombinasi hormon PMSG, AD dan rGH dapat merangsang perkembangan testis ikan sidat ukuran 140-150 g serta memacu pertumbuhan 0,514 %.

Abstract

Amazon armored catfish (Loricariidae) Pterygoplichthys pardalis is abundant in the Ciliwung River and consumed by local people. The present status of the Ciliwung River is polluted by heavy metals and fishes from this river may have the potential hazardous effect on human health. The aim of this study was to analyze the concentration of heavy metals (Cd, Hg, and Pb) in Amazon armored catfish organs from the Ciliwung River. Fish collection and water sampling were conducted in the rainy and dry seasons in three parts of the Ciliwung River, i.e. Bogor (upstream), Depok (middle), and Jakarta (downstream). Heavy metal concentrations were measured by atomic absorption spectrophotometer (AAS). One-way analysis of variance (ANOVA) and Tuckey’s test using R.i386 3.0.0 were performed to access whether heavy metal concentrations varied significantly between location, season, organ and heavy metal. The average of Cd concentrations in the gills, liver,and muscle were 0.000146 ^g.g'1; 0.000828 ^g.g'1; 0.000075 ^g.g'1, respectively. The average of Hg concentrations in the gills, liver, and muscle were 0.002826 ^g g-1; 0.004333 ^g g-1; 0.003960 ^g.g'1 respectively. The average of Pb concentrations in the gills, liver, and muscle were 0.002571 ^g g-1; 0.005467 ^g g-1; 0.001609 ^g.g'1 respectively. The concentration of heavy metals in fish organs were below the permissible limits of the environmental standard of Indonesia and FAO. Heavy metal concentrations in the water were below the baseline of the Indonesia Government Regulation. ANOVA clearly revealed that there was no significant variation of the heavy metal concentrations among the sites and seasons, however the significant difference was found among the organs and type of heavy metal. Local people should be aware because some heavy metals have the tendency to accumulate in various organs of Amazon armored catfish in the Ciliwung River. Abstrak Ikan sapu-sapu (Loricariidae) melimpah di Sungai Ciliwung dan dimanfaatkan sebagai salah satu sumber protein he-wani. Kondisi perairan Sungai Ciliwung ditengarai tercemar logam berat dan jika mengkonsumi ikan sapu-sapu dari sungai ini akan beresiko bagi kesehatan. Penelitian ini bertujuan untuk menganalisis konsentrasi logam berat (Cd, Hg, dan Pb) pada beberapa organ ikan sapu-sapu dari Sungai Ciliwung. Sampel ikan dan air sungai diambil pada musim peng-hujan dan kemarau di tiga lokasi sepanjang Sungai Ciliwung, yaitu Bogor (hulu), Depok (tengah), dan Jakarta (hilir). Konsentrasi logam berat diukur menggunakan spektrofotometer serapan atom (SSA), dianalisis menggunakan uji ANOVA dan dilanjutkan dengan uji Tuckey dengan bantuan program R.i7386 3.0.0. Rata-rata konsentrasi Cd pada in-sang, hati, dan otot ikan berturut-turut 0,000146 ^g.g'1; 0,000828 ^g.g'1; 0,000075 ^g.g'1. Rata-rata konsentrasi Hg pada insang, hati, dan otot ikan berturut-turut 0,002826 ^g.g'1; 0,004333 ^g.g'1; 0,003960 ^g.g'1. Rata-rata konsentrasi Pb pada insang, hati, dan otot ikan berturut-turut 0,002571 ^g.g'1; 0,005467 ^g.g'1; 0,001609 ^g.g'1. Konsentrasi ketiga logam berat pada organ ikan maupun air sungai berada di bawah nilai ambang batas menurut Standar Nasional Indonesia, FAO, maupun Peraturan Pemerintah Republik Indonesia. Uji ANOVA menunjukkan bahwa konsentrasi logam berat pada organ tubuh ikan berdasarkan lokasi dan musim tidak berbeda nyata, namun konsentrasi logam berat antar organ target dan jenis logam berbeda nyata. Perlu kehati-hatian dalam mengkonsumsi ikan sapu-sapu dari Sungai Ciliwung karena beberapa logam berat telah terdeteksi pada organ ikan tersebut.

Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) are the most toxic pollutants among the hydrocarbon families and their existence in the marine environment are harmful to aquatic organisms and human because of their mutagenic and carcinogenic properties. The purpose of this study was to identify the component of PAHs and their concentration in the water, sediment and their accumulation in the muscle and liver of the Harpadon nehereus. Water and sediment samples were collected in the three locations and fish sample in one location surrounding the Tarakan Island in September 2010. All samples were extracted using a soxhlet apparatus, and injected to the gas chromatography-mass spectrometry (GC-MS Shimadzu QP2010, with a detection limit of 0.001 ppb) after being cleaned up for identification. Total PAH concentrations ranged from 6.36-380 ^g/l and 50-136 ng/g in the water and sediment, respectively. Total PAH concentrations in muscle and liver ranged from 605-1067 ng/g and -1679 ng/g, respectively. There was an indication that the Tarakan waters has been contaminated by PHAs which derived from coastal activities, and PHAs accumulated in the body of H. neherus. Abstrak Hidrokarbon aromatik polisiklik (PAH) merupakan bahan pencemar beracun dari kelompok hidrokarbon dan keberada-annya di lingkungan laut berbahaya bagi organisme akuatik dan manusia karena bersifat mutagenis dan karsinogenis.
