Abstract

Pangasianodon hypophthalmus grows well in a dark tank completed with an aquaponic system.  To improve the growth, a feed supplement made from Moringa oleifera might be used as it is rich in protein, vitamins A, B, C, and minerals. To understand the effect of  M.oleifera addition in the feed of fish, research has been conducted in June-July 2022. M. oleifera leaves were dried and powdered and then mixed with commercial fish feed pellets. There were 4 treatments of M. oleifera dosages, namely T0 (no M. oleifera), T1 (10 g/kg), T2 (15 g/kg), and T3 (20 g/kg). The fish was reared in a 100L container (30 fishes/tank, around 4 g BW and 8 cm TL), covered with a dark-colored tarp, and completed with the aquaponic system using Ipomoea aquatica. The feed was given 2 times/day, ad libitum. Samplings were conducted once/10 days, for 40 days. Results showed that the survival of fish in all treatments was 93.3 – 98.89%. The growth of fish, however, was different. There was no difference in fish body weight (BW), total length (TL), and specific growth rate (SGR) of fish fed with Moringa, they were around 23.5 g BW, 5.8 cm TL, and 4.3 cm SGR respectively. While those of the control fish were 13.0 g BW, 4.23 cm TL, and 2.89% per day SGR respectively. The fish that was fed with Moringa-enriched pellets showed the highest Feed Efficiency (90.42-97.46%) and the lowest FCR (1.03 – 1.11). While in the fish that was not fed with Moringa showed the lowest   FE (75.48%) and the highest FCR (1.33%). Data obtained indicate that Moringa positively improves the growth of fish as well as improving feed efficiency

Abstract

Salah satu Tempat Pelelangan Ikan (TPI) yang terdapat di daerah Sibolga adalah Pelabuhan Perikanan Nusantara (PPN) Sibolga. TPI merupakan tempat pendaratan ikan oleh para nelayan untuk menjual hasil tangkapannya setelah pulang dari laut. Ikan kembung merupakan salah satu jenis ikan yang didaratkan di TPI Sibolga yang cukup diminati oleh masyarakat Sibolga dan Tapanuli Tengah. Ikan ini berasal dari hasil tangkapan alam, yang dimana kondisi kualitas airnya tidak terkendali sehingga dapat menyebabkan ikan stres. Ikan yang stres dapat menurunkan imunitas tubuh sehingga mudah terkena patogen akibatnya tejadi penurunan mutu ikan. Tujuan penelitian ini adalah untuk mengidentifikasi dan mengkaji prevalensi, intensitas parasit, baik ektoparasit maupun endoparasit pada ikan kembung yang didaratkan di Tempat Pelelangan Ikan (TPI) Sibolga. Metode yang digunakan berupa deskriptif, Sedangkan pengambilan sampel dilakukan dengan jumlah sebanyak 60 sampel ikan kembung yang terdiri dari 40 sampel jantan dan 20 sampel betina. Panjang total ikan sekitar 150-280 mm dan berat 50-135 gram. Identifikasi dilakukan di Laboratorium Kesehatan Ikan STPK Matauli. Dari hasil penelitian 60 ekor ikan kembung yang diperiksa tidak ditemukan adanya infeksi ekstoparasit. Sedangkan untuk infeksi endoparasit ditemukan hanya pada ke 40 ekor sampel ikan kembung laki-laki saja, yang terdiri dari Acanthocephalus sp. (menyerang organ usus) dan Anisakis simplex (menyerang bagian daging). Prevalensi parasit Acanthocephalus sp. sebesar 100% dengan intensitas 4,25 ind/ekor dan parasit Anisakis simpleks sebesar 22,5% dengan intensitas 1,40 ind/ekor.
