Effect of Feeding Fermented Leucaena leucocephala Seed Meal on Growth and Protein Content of Osphronemus gouramy Juvenile

Abstract

Gouramy (Osphronemus gouramy Lac.) is one of the original fish from Indonesia that lives in fresh water and has high economic value because of its dense texture, high nutrition, and delicious taste so that it is widely favored by Indonesians. The results of juvenile cultivation activities have not been going well so far, this is because the growth of gouramy’s juvenile is slower than the growth of other freshwater fish’s juvenile. One alternative that can increase the growth and protein content of gouramy juvenile is to utilize of the availability of lamtoro seeds. The purpose of this study was to determine the effect of feeding lamtoro seed fermentation on growth and protein content of gouramy’s juvenile. This study used experimental method with a completely randomized design (CRD with 6 treatments and 4 replications). Data were analyzed using Analysis of Variance Test (ANOVA) and further test in the form of Honest Significant Difference (Tukey HSD Test) at the 95% confidence level. The results showed that P3 with the addition of fermented lamtoro seed flour 40% can increase the growth and protein content of gouramy juvenile. The conclusion of this study was lamtoro seed fermented feed has effect in increasing growth and protein content of gouramy’s juvenile.

Effect of Vitamin C Bioencapsulation in Natural Feed on Protein, Fat, Energy, and Mortality of Milkfish Larvae (Chanos chanos)

“…Measurement of the energy retention of milkfish larvae obtained results in the range of 8.39 ± 0.123%, while the highest energy retention was found in the 200 mgL -1 treatment, which was 12.38 ± 0.05%, and the lowest energy retention was in the 0 mgL -1 treatment, which was 8.39 ± 0.123%. Protein retention illustrates the quantity of protein delivered that can be absorbed and used to construct or repair damaged body cells and utilized for daily metabolism (Kurniawan et al, 2017;Ananda et al, 2022). According to Setiawati et al (2013), Protein retention is the accumulation of proteins derived from diet and retained in the fish's body.…”

Intensifikasi Budidaya Perikanan (Osphronemus Gouramy) Mandiri Berbasis Sumberdaya Lokal sebagai Upaya Peningkatan Produktivitas POKDAKAN Mina Sida Karya

“…Indonesia memiliki potensi alam yang mendukung untuk pengembangan berbagai usaha budidaya air tawar (Budiana & Rahardja, 2018) salah satunya yaitu budidaya ikan osphronemus gouramy. Menurut (Ananda, Safrida, Khairil, Hasanuddin, & M.D., 2022), ikan osphronemus gouramy merupakan komoditas perikanan air tawar dengan permintaan yang cukup besar dan harga yang cukup mahal dibandingkan dengan ikan air tawar lainnya. Hal ini dikarenakan 60-85% keberhasilan budidaya ikan osphronemus gouramy ditentukan oleh ketersediaan pakan ikan yang berkualitas sebagai sumber protein untuk pertumbuhan ikan.…”
