Oryzias marmoratus is one of the ornamental aquarium fish species that live endemic to Towuti Lake, South of Sulawesi, Indonesia. However, the fish has been categorized as near threatened by IUCN. A current report showed the fish could be cultivated. This research aims to improve the reproduction quality in cultivation by using artificial feed containing Spirulina (A=0, B=3, and C=6) % dry weight. The study was conducted with two replications using an aquarium (80 x 40 x 40 cm) for 40 days (October-December 2020) at Research Center for Limnology-LIPI. Each aquarium contains 21 broodstock (female: male = 2:1). Observation parameters are the total number of spawning/ToS (time), ovulated eggs number/OEN, fertilization ability/FA (%), hatching ability/HA (%), number of larvae/NoL, the egg of incubation time/EIT (day), survival of larvae seven days old after hatching/SR7 (%). Based on descriptive analysis, the use of feed C (containing 6% Spirulina) produced the highest values of ToS, OEN, %HA, NoL, and SR7 (%) were ten times; 89 eggs; 89 larvae, 100%; and 98.89±3.51% respectively. Spirulina could increase the reproduction viability and is presumed to enhance feed efficiency of Oryzias marmoratus, but the optimum levels have not been obtained.

Telah dilakukan penelitian pengaruh penambahan asap cair termpurung kelapa terhadap pertumbuhan Spirulina sp. Penelitian ini divariasikan dalam 3 perlakuan media yaitu perlakuan A (media f/2 Guillard), perlakuan B (media campuran f/2 Guillard + asap cair) dan perlakuan C (media asap cair). Ketiga perlakuan berada pada kondisi lingkungan dengan suhu 29-30 ⁰C, salinitas 20 ‰, pH 8 dan intensitas cahaya 3000 lux. Pengukuran pertumbuhan Spirulina sp dilakukan menggunakan alat Spektrofotometer Shimadzu UV 1280. Hasil penelitian menunjukkan bahwa perlakuan B yaitu media campuran f/2 Guillard dan asap cair menghasilkan pertumbuhan paling optimal dengan koefisien laju pertumbuhan tertinggi sebesar 0,238/hari, diikuti perlakuan C sebesar 0,176/hari dan perlakuan A sebesar 0,139/hari. Penelitian ini membuktikan bahwa asap cair tidak hanya digunakan sebagai biosida namun dapat digunakan sebagai media pertumbuhan.

Silvoaquaculture is a model of brackish water ponds that combines aquaculture with mangrove conservation. This study examines aspects of feed conversion ratio (FCR) and survival rate (SR) as benchmarks for milkfish production that are maintained in three different types of silvoaquaculture ponds (Empang Parit, Komplangan, and Kao-kao Ponds). This research was conducted in Indramayu Residence (Indonesia). Data collected by questionnaires and determination of the respondents was done by purposive sampling with the aim of getting fish farmers in silvoaquaculture ponds. Data analysis uses a statistical test approach (ANOVA and DMRT). The milkfish that are cultivated in silvoaquaculture ponds have a survival rate ranging from 25.00%-80.00% with an average of 52.98%. Survival rate between types of silvoaquaculture ponds was different; Empang Parit ponds produce the lowest survival rate (average = 44.98%) and Kao-kao ponds have the highest survival rate (average = 59.64%). Mangroves become predatory animal habitats, so milkfish survival in silvoaquaculture ponds is low. The best feed conversion ratio of a Kao-kao pond is 1.63, followed by a Empang Parit of 1.82, and a Komplangan of 1.92. Feed conversion ratio between types of silvoaquaculture ponds was not significantly different. Mangrove ecosystems contribute to high nutrient waters, so natural food grows well and becomes additional feed for milkfish.
