Abstract

The research on reproductive biology of Indian oil sardine was carried out from October to December 2012 in Kendari Bay, Southeast Sulawesi. The objective of this research was to describe aspects of the reproductive biology of Indian oil sardine such as sex ratio, gonadal maturation, gonadosomatic index, fecundity, and length at first maturity (Lm50). Fish collection was done using experimental gillnets (with different mesh sizes of %, 1, 1%, and 1% inches). The gonadal maturation of fish was determined morphologically by comparing the shape, size, color, and gonad weight. A total of 1794 individual fish were caught with ranging 88-216 mm in length and 5.7- 30.4g in weight. The sex ratio of female was more dominant than the male. The gonadosomatic index of male and female were higher at Zone III (4.32±4.33 and 5.03±5.04) and in December (4.11±1,32 and 5.14±1.6), while length at first maturity (Lm50) of female and male were 122-132 mm. Fecundity of fish in weight of 9.8-30.4 g were varied from 501 to 17,446.

Abstract

Two experiments were conducted to evaluate the utilization of corn distillers dried grain with soluble (DDGS) as plant raw material for giant gourami Osphronemus goramy diet. The digestibility of protein and dry matter was observed in the first experiment by using indirect methods and Cr2O3 was used as a tracer. A forty days feeding experiment was performed on the second stage of experiment to observe the effect of DDGS levels on the growth and feeding performance of giant gourami. The juvenile giant gourami were used in the experiment with initial weight around 4.7±0.78 g and reared in aquarium (35 x 40 x 50 cm3) and filled with 50 L treated water at a density of 0.2 fish L"1. Four experimental diets was formulated with contain similar protein (40%) and energy 500 kcal GE 100 g-1, but differ in the levels of DDGS that were 0, 10%, 20%, and 30% (Diet A, B, C and D). Fish were fed three times daily at the satiation levels. A completely randomized experimental design consisted of four treatments and three replicates were used. The result showed that DDGS digestibility value of protein and total was 85.35% and 70.10% respectively. Increasing DDGS levels in the diet could not effect significantly on survival rate, daily growth rate and feed consumption (P>0.05). Feed efficiency and protein retention on fish fed with DDGS content of up to 20% were not different compared with the control diet (0%); whereas, feeding with diet D (DDGS 30%) were reduced feed efficiency and protein retention. In conclusion, the diet containing DDGS at the level of 20% (diet C) was support the best growth performance of juvenile gouramy. Abstrak Dua macam penelitian dilakukan untuk mengkaji pengaruh penggunaan distillers dried grain with solubles (DDGS) sebagai sumber protein nabati terhadap pertumbuhan benih ikan gurame Osphronemus goramy Lac. Penelitian ini terdiri atas penelitian kecernaan dan kinerja pertumbuhan. Pada pengukuran kecernaan digunakan motede tidak langsung dengan menggunakan kromium trioksida (Cr2O3) sebagai indikator. Pada penelitian kinerja pertumbuhan digunakan empat macam pakan dengan isoprotein (40%) dan isoenergi (500 kcal GE 100 g-1) dengan kadar DDGS yang berbeda. Pakan A (pakan kontrol, DDGS 0%) sedangkan pakan B, C dan D mengandung DDGS masing-masing sebesar 10, 20 dan 30%. Juwana ikan gurame dengan bobot rata-rata 4,7±0,78 g dipelihara selama 40 hari dalam akuarium berukuran 35 x 40 x 50 cm3 dengan kepadatan 0,2 ekor per liter. Ikan diberi pakan sampai kenyang dengan frekuensi tiga kali se-hari. Hasil penelitian menunjukkan bahwa ikan gurame mampu mencerna protein DDGS sebesar 85,35% dan 70,10% untuk total bahan. Peningkatan DDGS dalam pakan tidak memberikan pengaruh yang nyata terhadap konsumsi pakan, laju pertumbuhan harian dan kelangsungan hidup benih ikan gurame (p>0,05). Ikan yang diberi pakan dengan kandungan DDGS hingga 20% memiliki nilai efisiensi pakan dan retensi protein yang tidak berbeda dibandingkan dengan pakan kontrol; sedangkan pemberian DDGS sebesar 30% dalam pakan menurunkan nilai tersebut. Dapat disimpulkan bahwa pakan C dengan kadar DDGS 20% dalam pakan memberikan hasil yang terbaik terhadap kinerja pertumbuhan benih ikan gurame.

Abstract

The research was conducted from July-August 2012 to examine day and night abundance and community structure of fish in seagrass area of Tanjung Tiram, Inner Ambon Bay. Fish were collected by swept area method using beach seine over the seagrass areas. Fish samples were collected six times (three times for each day and night). It was found that total number of individual fish as much as 5593 individuals from 72 species and 35 families. Siganus canaliculatus dominated the fish community structure at both day and night time. Ostorhinchus lateralis more active at night time, whereas Aeoliscus strigatus more active at day time. Fish community structure varied between day and night, index of dominancy was slightly higher at night, whereas index of diversity was higher during day time as well as the evenness index. Variability in abundance and community structure of fish between day and night were associated with nocturnal and diurnal fish charachetristic, and oceanographic parameters. Temperature, salinity, dissolved oxygen and pH were positively affected fish abundance; whereas the level of turbidity was negatively. Abstrak Penelitian ini dilaksanakan di perairan Tanjung Tiram , Teluk Ambon Dalam selama bulan Juli-Agustus 2012, untuk membandingkan kelimpahan dan struktur komunitas ikan padang lamun berdasarkan perbedaan siang dan malam hari. Ikan dikoleksi dengan metode sapuan menggunakan pukat pantai yang ditarik pada hamparan padang lamun sebanyak enam kali (masing-masing tiga kali mewakili siang dan malam hari). Hasil penelitian mendapatkan total jumlah individu ikan sebanyak 5593 individu dari 72 spesies dan 35 famili. Siganus canaliculatus mendominasi struktur komunitas ikan baik pada siang maupun malam hari, Ostorhinchus lateralis aktif pada malam hari, dan Aeoliscus strigatus yang aktif pada siang hari. Terdapat variasi struktur komunitas ikan antara siang dan malam, dengan nilai dominansi selalu lebih tinggi pada malam hari. Sebaliknya, keanekaragaman selalu tinggi pada siang hari dan keseragaman spesies lebih stabil pada siang hari. Variabilitas kelimpahan dan struktur komunitas ikan antara siang dan malam hari selain berkaitan dengan sifat nokturnal dan diurnal, juga dipengaruhi fluktuasi parameter oseanografi. Suhu, salinitas, oksigen terlarut, dan pH berpengaruh positif, sedangkan kekeruhan perairan berpengaruh negatif terhadap kelimpahan ikan di ekosistem padang lamun.

Abstract

The endemic fish, egg-carrying buntingi (Adrianichthys oophorus) is a small fish that consumed by local people around Lake Poso, Central Sulawesi. Local people catch this species with non-environment friendly activities and probably this species would be threatened. Scientific information is required to determine the appropriate management strategies, for example fish reproductive biology; while the information about reproductive biology of egg-carrying buntingi is still unkown. The study was conducted in four months (October 2011- February 2012) at Bio-Macro Laboratory, Department of Aquatic Resources Management, Faculty of Fisheries and Marine Science and Histopathology Laboratory, Faculty of Veterinary Medicine, Bogor Agricultural University. All egg-carrying buntingi were collected from the fishermen at Lake Poso and preserved in 5% formalin. Microanatomy of ovarian made by HE staining method and observed by using light microscope. The result showed that egg-carrying buntingi has sexual dimorphism (t-test, a = 0.05), where female one has a longer pelvic fins size than male. Pelvic fin in female has a function to incubate the eggs. This fish has a single ovary with oval-shaped pouch. The Largest ovarian size has about 5 mm length and 3 mm width, which the position is extending under the stomach. Based on macroscopic analysis, the developmental level of egg-carrying buntingi ovarian are divided into four phases i.e. I (initial development phase), II (development phase), III (maturation phase), and IV (spent phase). Abstrak Ikan endemik rono (Adrianichthys oophorus) merupakan ikan berukuran kecil yang dikonsumsi masyarakat di sekitar Danau Poso. Penangkapan ikan ini tidak ramah lingkungan sehingga ketersediaannya di alam menjadi terancam. Diperlukan berbagai informasi ilmiah untuk menetapkan strategi pengelolaan yang tepat, di antaranya informasi biologi reproduksi ikan ini. Hingga saat ini informasi tersebut masih sangat kurang. Untuk mengisi kekurangan informasi tersebut maka penelitian ini dilakukan. Penelitian dilakukan selama empat bulan (Oktober 2011-Februari 2012) di Laboratorium Biomakro Departemen Manajemen Sumber Daya Perairan FPIK dan Laboratorium Histopatologi FKH IPB. Ikan rono diambil dari hasil tangkapan nelayan di Danau Poso, diawetkan dalam larutan formalin 5%. Preparat mikroana-tomi ovarium dibuat dengan metode pewarnaan HE, selanjutnya pengamatan dilakukan dengan menggunakan mikroskop cahaya. Ikan rono memiliki dimorfisme seksual yaitu ikan betina memiliki ukuran sirip perut yang lebih panjang daripada ikan jantan. Sirip dada ikan rono betina lebih panjang yang berfungsi sebagai tempat untuk mengerami sekumpulan telurnya sampai menetas. Ikan ini memiliki ovarium tunggal berbentuk kantung oval. Ukuran ovarium terbesar memiliki panjang sekitar 5 mm dan lebar 3 mm dengan posisi lateral di bawah rongga perut. Ovarium ikan rono memiliki oosit dengan semua fase perkembangan, digolongkan ke dalam tipe ovarium yang perkembangan oosit-nya tidak bersamaan. Berdasarkan analisis makroskopis ovarium ikan rono, tingkatan perkembangan ovarium dibagi dalam empat fase yaitu: I (fase perkembangan awal), II (fase perkembangan), III (fase pematangan), dan IV (fase salin).

Abstract

The purpose of this study was examine the potential of earthworm flour (Lumbricus sp.) as a substitute for fish meal in feed on growth performance, body composition, liver and muscle glycogen levels in milkfish. Completely randomized design (CRD) with four treatment levels of fish meal substitution with flour earthworms in artificial feeding of milk fish, namely 0, 34.62; 65.38; and 100%. Fish with initial weight 0.95 ± 0.11 g reared in aquariums of 50 x 40 x 35 cm3 with a recirculation system, with a density of 15 fish in each experimental unit. Fish were fed at 07:00 am and 16:00 pm with a percentage of 5% of body weight per day. Rearing was carried out for 60 days. The result showed that milkfish fed with different levels of fish meal substitution with earthworm flour have the same effect on feed intake, feed efficiency, protein retention and fat, as well as survival, body proximate composition, and the levels of glycogen in the liver and muscles. The highest levels of fish meal substitution with earthworm flour (100%) can increase the growth relative of milkfish up to the maximum (1216.91 ± 14.22%). In conclusion, earthworm flour can replace the role of fish meal in feed formulation for milkfish culture up to 100%. Abstrak Tujuan penelitian ini mengkaji potensi tepung cacing tanah (Lumbricus sp.) sebagai pengganti tepung ikan dalam pakan terhadap kinerja pertumbuhan, komposisi tubuh, kadar glikogen hati dan otot ikan bandeng. Desain penelitian menggu-nakan rancangan acak lengkap dengan empat perlakuan tingkat substitusi tepung ikan dengan tepung cacing tanah dalam pakan buatan ikan bandeng, yaitu: 0; 34,62; 65,38; dan 100%. Ikan uji dengan bobot awal 0,95±0,11 g dipelihara dalam akuarium berukuran 50 x 40 x 35 cm3 dengan sistem resirkulasi, dengan kepadatan 15 ekor pada setiap satuan percobaan. Pemberian pakan setiap pukul 07.00 dan 16.00 WITA dengan persentase 5% bobot badan per hari. Pemeliharaan dilakukan selama 60 hari. Hasil penelitian menunjukkan bahwa ikan bandeng yang diberi pakan dengan berbagai tingkat substitusi tepung ikan dengan tepung cacing tanah memberikan pengaruh yang sama terhadap konsumsi pakan, efisiensi pakan, retensi protein dan lemak, serta sintasan, komposisi proksimat tubuh, serta kadar glikogen di hati dan otot. Tingkat substitusi tepung ikan dengan tepung cacing tanah tertinggi (100%) dapat meningkatkan pertumbuhan bobot relatif ikan bandeng yang tertinggi (1216,91±14,22%). Dengan demikian, tepung cacing tanah dapat menggantikan peranan tepung ikan hingga 100% dalam formulasi pakan untuk budi daya ikan bandeng.
