Abstract

In outdoor cultivation at Amal Beach, three seeding mass selections were reared for 30 days for each cycle. Each variety had a different DGR %/day (Daily Growth Rate %/day) value at the end of the growing season on G1-G2-G3 ranging from 3.62-5.90 %/day, which were still categorized as good, and G3 var.Lampung had the highest DGR value. Carrageenan yield values in this study, G1 to G3, ranged from 23.16% to 45.87%, where the G3 G2 G1 treatment. The best thallus samples (20% were selected for each generation) resulted in carrageenan yield sample population in each variety, where var.Lampung var.Tarakan var.Kupang. The biplot analysis shows that the DGR variable vector coincides with the IAA, Phosphate, Gibberellin, and Ammonia vectors. Ammonia stepwise regression analysis (sig) affects DGR with an Ammonia coefficient value of 4.89; meaning that for each increase in the Ammonia value by one unit, the estimated mean value of DGR will increase by 4.89. Thus, the application of themassbased on the results of this study was able to increase the DGR valueKappaphycus alvarezii,which in turn produce the highest yield of carrageenan withK. alvareziivar.Lampung G3 was the best seed candidate to be developed at the seaweed cultivation site in Tarakan City.Keywords:AlgaePhytohormonesCarrageenanNitrogenViscosity

Abstract

This study aims to evaluate the effect of stocking density variation on the survival rate of Asian Redtail catfish juveniles (Mystus nemurus) in a closed wet transportation system for 12 hours and post-transportation maintenance for 4 days. The method used a completely randomized design with three density treatments: 83, 167, and 250 fish per liter, each replicated three times. The results showed that a stocking density of 167 fish per liter provided the best survival rate, reaching 100% at the end of transportation and 95,45% after post-transportation maintenance. At the highest density of 250 fish per liter, a significant decline in survival to 64,39% was observed, accompanied by decreased water quality, lowered dissolved oxygen levels, increased ammonia concentration, and physiological stress symptoms in the juvenile. The decline in water quality and accumulation of metabolic waste at high densities contributed to increased stress and mortality. Besides the biological aspects, the business analysis indicated that a stocking density of 167 fish per liter was optimal in terms of economic efficiency, generating a net profit of IDR 21.467 and an R/C ratio of 1,09, making this scenario commercially viable. This study offers valuable recommendations for the sustainable management of Asian Redtail catfish juvenile transportation, promoting increased production and profitability in aquaculture.

Abstract

The major constraints in soft-shell crab (Scylla serrata) culture are the irregular and low frequency of molting, which reduce production efficiency. Previous studies have shown that purslane (Portulaca oleracea) supplementation significantly improves molting and production performance of soft-shell crab cultured in an apartment box using a recirculating aquaculture system; however, evaluations at higher doses remain limited.  This study aimed to evaluate the effectiveness of dietary supplementation with purslane stems and young leaves and to determine the optimal dose to enhance soft-shell crab growth and molting. The study used a completely randomized design (CRD) with four treatments and three replicates, namely P0 (yellowstripe scad without purslane), P60 (yellowstripe scad + 60 g kg-1 purslane), P70 (yellowstripe scad + 70 g kg-1 purslane), and P80 (yellowstripe scad + 80 g kg-1 purslane). The results showed that purslane supplementation significantly increased molting and improved growth performance (P < 0.05). Treatment P70 yielded the highest molting percentage of 76.6% and growth rate of 1.3 g day⁻¹. Meanwhile, the control treatment (P0) only achieved a molting percentage of 36.6% and a growth rate of 1.07 g day⁻¹. These findings indicate that purslane has a potential as a natural feed additive to enhance molting and growth performance in soft-shell crab culture. The dose of 70 g kg-1 feed can be recommended to achieve the best molting response of soft-shell crab reared in a recirculating aquaculture system using the apartment box. Kendala utama dalam budidaya kepiting soka (Scylla serrata) adalah proses molting yang tidak serempak dan frekuensinya yang rendah, sehingga menurunkan efisiensi produksi. Penelitian sebelumnya menunjukkan bahwa suplementasi krokot (Portulaca oleracea) dapat meningkatkan molting dan kinerja produksi kepiting soka yang dibudidayakan dalam sistem kotak apartemen berbasis resirkulasi; namun, evaluasi pada dosis yang lebih tinggi masih terbatas. Penelitian ini bertujuan untuk mengevaluasi efektivitas suplementasi batang dan daun muda tanaman krokot dalam pakan serta menentukan dosis optimal untuk meningkatkan pertumbuhan dan molting kepiting soka. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga ulangan, yaitu P0 (ikan selar tanpa penambahan krokot), P60 (pakan ikan selar + 60 g kg-1 krokot), P70 (pakan ikan selar + 70 g kg-1 krokot), dan P80 (pakan ikan selar + 80 g kg-1 krokot). Hasil penelitian menunjukkan bahwa suplementasi krokot secara signifikan meningkatkan molting dan kinerja pertumbuhan (P < 0,05). Perlakuan P70 menghasilkan persentase molting tertinggi sebesar 76,6%, dan laju pertumbuhan 1,3 g hari-1. Sementara itu, perlakuan kontrol (P0) hanya mencapai persentase molting sebesar 36,6% dan laju pertumbuhan sebesar 1,07 g. hari-1. Hasil ini menunjukkan bahwa tanaman krokot berpotensi sebagai bahan tambahan pakan alami untuk meningkatkan molting dan pertumbuhan pada budidaya kepiting soka. Dosis 70 g kg-1 pakan dapat direkomendasikan untuk menghasilkan respons molting terbaik pada kepiting soka yang dipelihara dalam sistem resirkulasi dengan metode kotak apartemen.
