Abstract

Ikan nilem merupakan ikan air tawar asli Indonesia yang persebaranya hanya di daerah Jawa Barat. Induk betina ikan nilem memiliki jumlah telur yang bervariasi sehingga perlu dilakukan seleksi. Seleksi yang dapat dilakukan pada induk betina ikan nilem yaitu dengan cara melihat karakter morfometrik. Sampai saat ini penelitian tentang ikan nilem khususnya yang berkaitan dengan reproduksi juga masih sangat jarang dilakukan. Tujuan dilaksanakanya penelitian ini adalah untuk menganalisis hubungan dan mengetahui karakter morfometrik yang paling berhubungan terhadap fekunditas. Metode yang digunakan dalam penelitian iniyaitu deskripstif komparatif dengan pendekatan kuantitatif. Parameter yang diamati meliputi panjang standar, tinggi badan, lingkar tubuh, dan bobot tubuh. Kelompok sampel ikan uji diukur berdasarkan panjang standar yang telah ditentukan, yaitu 06,1-09 cm, 09,1-12 cm, 12,1-15 cm, 15,1- 18 cm, 18,1-21 cm. Hasil penelitian menunjukkan bahwa morfometrik berpengaruh terhadap fekunditas. Karakter morfometrik terhadap fekunditas diperoleh hasil tertinggi pada lingkar tubuh dengan fekunditas sebesar 99%terhadap fekunditas yang dihasilkan pada induk betina ikan nilem. Faktor yang dapat mempengaruhi jumlah fekunditas diantaranya yaitu umur ikan, lingkungan, makanan, dan diameter ikan. Diameter ikan sangat berpengaruh terhadap jumlah fekunditas yang di hasilkan, semakin besar diameter telur dalam suatu gonad maka akan semakin sedikit jumlah telur yang dihasilkan.

Abstract

ABSTRACT Snakehead fish Channa striata is one of freshwater commodity which has high economic value. Nowadays, snakehead fish stock mostly comes from wild capture. Artificial spawning with hormonal induction is usually used to improve broodstock efficiency, as well as the quality and quantity of fish seed production. Purpose of this study was to determine the effectiveness of prostaglandin 2α (PGF2α) hormone on ovulation time and count of ovulated eggs. This experiment used 30–40 cm broodstock with 600–900 g body weight. Fishes were acclimated for one week in a container and then injected with different doses of PGF2α, namely: control without PGF2α (P1), 0.5 mL/kg (P2); 0.7mL/kg (P3); and 0.9 mL/kg (P4). Each treatment consisted of three fishes as replication. Ovulation time was observed until 72 hours post injection. The results showed that PGF2α injected broodstoks ovulated faster (9.17–12.24 hours post injection) than control P1 (22.67 hours), while among PGF2α injected fishes were the same. Furthermore, count of ovulated eggs from PGF2α induced broodstocks were higher than control P1, and the highest (2,860 eggs) was obtained in treatment 0.9 mL/kg. Thus, PGF2α at dose of 0.9 mL/kg can be used to induce eggs ovulation of snakehead fish and to increase count of ovulated eggs. Keywords: PGF2α, ovulation time, ovulated eggs count, Channa striata  ABSTRAK Ikan gabus Channa striata merupakan salah satu komoditas air tawar yang mempunyai nilai ekonomi tinggi. Saat ini, pemenuhan kebutuhan hanya bergantung pada hasil penangkapan di alam. Cara pemijahan buatan dengan induksi hormon biasanya digunakan untuk efisiensi penggunaan induk serta peningkatan kualitas dan kuantitas benih ikan yang dihasilkan. Tujuan dari penelitian ini adalah untuk menguji efektivitas hormon prostaglandin 2α (PGF2α) terhadap waktu ovulasi dan jumlah telur ikan gabus yang diovulasikan. Penelitian ini menggunakan induk ikan gabus berukuran 30–40 cm dengan bobot tubuh 600–900 g. Ikan diadaptasikan di wadah penelitian selama seminggu, kemudian diinjeksi hormon PGF2α dengan perlakuan hormon dengan dosis berbeda, yaitu: kontrol tanpa hormon (P1), 0,5 mL/kg (P2); 0,7 mL/kg (P3); dan 0,9 mL/kg (P4). Setiap perlakuan terdiri atas tiga ekor induk sebagai ulangan. Waktu ovulasi diamati sampai dengan 72 jam pascasuntik. Hasil penelitian menunjukkan bahwa induk yang disuntik PGF2α memijah lebih cepat (9,17–12,24 jam pascasuntik) daripada kontrol (22,67 jam), sedangkan antarperlakuan hormon PGF2α tidak berbeda. Selanjutnya, jumlah telur diovulasi dari induk ikan gabus yang disuntik PGF2α berjumlah lebih banyak daripada kontrol. Hasil tertinggi (2.860 butir) diperoleh dari perlakuan 0,9 mL/kg.  Dengan demikian, hormon PGF2α dosis 0,9 mL/kg dapat digunakan untuk mempercepat waktu ovulasi ikan gabus, dan meningkatkan jumlah telur yang diovulasikan. Kata kunci: PGF2α, waktu ovulasi, jumlah telur diovulasi, Channa striata

Abstract

The Serayu River is one of the longest rivers in Central Java. Dams built in the lower reaches of the Serayu River are thought to block the migration paths of fish and aquatic macrocrustaceans. This study aimed to determine the effect of dam on Varuna litterata migration and its molecular identification. This research was conducted using the observation method. Migration observations were made on vertical paths while molecular identification of V. litterata in the lower reaches of the Serayu River was compared with existing data in GenBank. The study covered the freshwater area above the Serayu Dam, the open area with freshwater below the Serayu Dam, and the open area with brackish water at the estuary of the Serayu River, with a study length of 33.37 km. The results showed that the presence of dams in the lower reaches of the Serayu River inhibited the migration pattern of V. litterata. The vertical shape of the dam causes only a few V. litterata to migrate to the top of the dam. The dam in the lower reaches of the Serayu River resulted in not many V. litterata being able to migrate to the top of the dam, so there were very few V. litterata found in the population upstream of the dam (115 ind). The results of molecular identification of V. litratata using the cytochrome C oxidase subunit I (COI) gene show that this crab is 100% the same as the data in GenBank and is closely related to Varuna yui and other Varunidae crab species.Keywords: Dams, Molecular, Migration, Serayu River, Varuna litterata

Abstract

Optimalisasi budidaya ikan dengan kepadatan tinggi bersamaan dengan peningkatan pemberian pakan akan menyebabkan penumpukan bahan organik. Penumpukan bahan organik ini seperti sisa pakan dan feses akan memperburuk kondisi pemeliharaan, yang pada akhirnya memengaruhi kelangsungan hidup dan pertumbuhan ikan. Kondisi fisiologis ikan akibat lingkungan yang tidak sesuai akan menyebabkan terjadinya perubahan kondisi histologis pada jaringan dan organ yang berperan dalam metabolisme ikan tersebut. Tujuan penelitian ini adalah menganalisis respon perbedaan padat tebar terhadap analisis histologis ginjal ikan nila merah (Oreochromis sp) yang dipelihara menggunakan sistem budikdamber. Penelitian dilakukan selama 28 hari di laboratorium reproduksi dan hidrobiologi Universitas Brawijaya. Pada penelitian ini menggunakan rancangan acak lengkap faktorial dengan perlakuan kepadatan (A (2 ekor/10L), B (4 ekor/10L), C (6 ekor/10L), D (8 ekor/10L) dan sistem (budikdamber dengan kangkung (a) dan tanpa kangkung (b)). Beberapa kerusakan organ ginjal yaitu kongesti, edema dan nekrosis. Perlakuan terbaik adalah Ab (2 ekor/10L tanpa kangkung) yaitu dengan nilai kerusakan paling sedikit.

Abstract

The potential of freshwater fisheries in local species such as hampal fish (Hampala macrolepidota) presents several research gaps, particularly in specific localities. Research on H. macrolepidota in East Java may serve as a foundation for future management and development of local species, especially given that H. macrolepidota aquaculture is rarely carried out. Morphological studies based on meristics and morphometrics can be used for broodstock selection in H. macrolepidota domestication efforts. In this study, 21 Hampala specimens were assessed based on morphometrics and meristics, and analysed using a significance test, PCA and dendrogram. The analysis results by PCA and dendrogram showed morphometric differences in the Probolinggo and Banyuwangi populations compared with the four Brantas River populations. In contrast, based on meristics, the entire population does not show apparent differences based on the population. The clear differences demonstrated in the Probolinggo and Banyuwangi populations morphometrically indicate local adaptation due to differences in water conditions.

Abstract

Galangal (Alpinia purpurata) is a herb and medicine plant that is found in Southeast Asia including Thailand, Malaysia, and Indonesia. It is known to have health benefits for its flavonoid, phytosterol, and phenols that are anti-oxidant, anti-cancer, and anti-fungal properties. The phytosterol also can be used for sex hormones production.The exploration of its uses in aquaculture are not yet fully understand. In this LC50-96 experiments were tested for its optimum dosage used in aquaculture by using zebrafish larvae (Danio rerio) as a model. The optimum dosage in the experiments were between 1—31,83 ppm for ethanolic extract of galangal and <0,83 ppm for methanolic extract of galangal. Its uses in aquaculture must be further explored by its effect in fishes behaviors or by the histology of the organs.
