Teknologi Pembenihan Abalon Haliotis squamata Untuk Meningkatkan Produksi Budidaya Secara Berkelanjutan

 

Abstract

Abalone has a specific taste, containing 71,99% protein; 3,2% lipid; 5,6% crude fiber; and 0,6% water. The selling price in the domestic market ranges from IDR 250.000-IDR 600.000 per kg depending on the size and in the international market it ranges from USD 22-USD 66 per kg depending on the quality and type. The hatchery activities begin with rearing broodstock until the gonads mature. It was placed in plastic crates with a density of 40-50 individuals/unit and fed with macroalgae. The parent which is ready to be spawned has developed gonad and covers the hepatopancreas organ over 50%, and carried out on a spawning container. Larvae rearing begins with a container that has been cultured with benthic diatom as the larvae feed. Abalone measuring 1-2 cm was harvested and transferred to seed maintenance containers. Seed maintenance was carried out for 2-3 months and produces abalone seeds ready for sale with a size of 3cm. Hatchery activities produce FR 60%, HR 85%, and SR 0,1-1%. Seed packaging was carried out using three stage, a net bag with a density of 75-100 individuals/bag, a plastic bag filled with 20 net bags/plastic sheet, and a styrofoam box filled with 1 plastic/box.


Budidaya Ikan Gurami Osphronemus gourami: Teknis Pembenihan dan Analisa Kelayakan Usaha

 Abstrak. 

Ikan gurami Osphronemus gouramy merupakan komoditas perikanan budidaya yang hidup di perairan tawar dan tergolong dalam perairan tenang. Kegiatan kajian teknis budidaya dilaksanakan di Unit Kerja Budidaya Air Tawar Sendangsari, Yogyakarta yang bertujuan untuk mengkaji secara teknis dan ekonomi kegiatan budidaya ikan gurami agar informasi yang diperoleh dapat dimanfaatkan oleh masyarakat pembudidaya untuk meningkatkan pengetahuan dan kemampuan dalam pengelolaan budidaya ikan gurami. Kegiatan pembenihan menggunakan rasio pemijahan jantan dan betina 1:3 secara alami. Kegiatan pembenihan menghasilkan fekunditas (FR) 81.08%, derajat penetasan telur (HR) 90.02%, tingkat kelangsungan hidup (SR) larva 71.74%, dan SR benih 82%. Benih yang dijual berukuran 4-6 cm/ekor ke pembudidaya gurami di daerah sekitar Sendangsari, Yogyakarta.
