Four isonitrogenous and isocaloric diets containing 75% SBM protein, either fermented or non-fermented (SBM and FSBM), and supplemented or not with organic Se (OS) (SBMOS and FSBMOS), were fed to triplicate groups of juvenile barramundi (Lates calcarifer) (initial weight of 5 g) for 75 days. A fishmeal (FM)-based diet formulated for juvenile barramundi was used as a reference diet. The growth of fish was significantly affected by either the interaction of SBM type or by the OS level. In fish fed diets supplemented with OS (SBMOS and FSBMOS), final weight (FW), specific growth rate (SGR) and weight gain (WG) were higher in fish fed the fermented SBM (FSBMOS) than in those fed the non-fermented SBM (SBMOS). The apparent digestibility coefficient (ADC) of protein was higher in the fish fed the fermented SBM, either supplemented or unsupplemented with OS. However, ther...

This study used the Complete Randomized Design (RAL) method with 3 treatments and 3 repeats with 3 types of natural feed, namely crickets (A), Hong Kong caterpillars (B), and white shrimp (C). The maintenance of super red arowana fish is carried out for 70 days with a frequency of feeding three times a day and given satiation (ad satiation). The results showed that the feeding of crickets for super red arowana fish gave the highest length of 0.84±0.08 cm, the highest specific growth rate of 6.00±0.59%, and the survival rate (SR) at the end of the study was 100%. The results of measuring water quality parameters, namely temperatures of 28.7° C -30.4 °C, pH 7.97-8.14, and dissolved oxygen 4.6-5.4 mg.l⁻¹, are in the optimal range for the maintenance of super red arowana fish.

Segmentasi usaha pembenihan mempunyai peranan penting pada sektor budidaya perikanan yang disertai dengan perkembangan unit hatchery yang cenderung semakin meningkat. Kualitas benur merupakan faktor yang sangat berpengaruh terhadap keberhasilan budidaya pada segmentasi pembesaran udang vaname sehingga perlu dilakukan suatu upaya dalam rangka mengatur kegiatan produksi benih udang vaname agar terciptanya benih yang berkualitas dengan keuntungan yang sepadan. Penelitian ini dilakukan untuk mengetahui performansi kinerja budidaya dan mengkaji analisis finansial tentang pembenihan udang vaname. Kajian dilakukan dengan metode observatif dan wawancara di PT. Esaputlii Prakarsa Utama selama 59 hari dan dilakukan studi literatur sebagai data sekunder pada isi kajian. Hasil kajian menunjukan bahwa rata-rata produktivitas larva udang vaname 23.160.000 ekor/siklus, FR 95%, HR 94%, dan SR 42%. ...
