Abstract

The aim of this study was to evaluate the effect of different culture media on the growth and carrageenan content of the seaweed Kappaphycus striatum. The study was conducted over 45 days in the waters off Oenaek Village, Kupang Regency, using three types of cultivation media: UV-treated plastic (Treatment A), mesh bags (Treatment B) and the conventional or long-line method (Treatment C), each with three replicates. The parameters observed included absolute weight growth, specific growth rate, and carrageenan content. The results showed that the conventional method (Treatment C) yielded the best results compared to the other treatments, with an average absolute weight growth of 296.99 g and a specific growth rate of 4.30% per day. The highest carrageenan content was also found in Treatment C, at 111 per cent. Statistical analysis using ANOVA showed no statistically significant effect on absolute growth and SGR (p > 0.05); however, from a biological perspective, the conventional medium yielded the most optimal results. These findings indicate that the conventional cultivation method (long line) is more effective in enhancing the productivity and quality of K. striatum seaweed.

Abstract

Silkworm flour is a natural ingredient, which has a high protein content that is suitable as a combination ingredient for milkfish feed. The purpose of this study was to determine the effect of providing a combination of silkworm flour (Tubifex sp) and commercial pellets on the growth and survival of milkfish (Chanos chanos). This study was conducted in the milkfish pond of Fahiluka Village, Central Malaka, East Nusa Tenggara for 60 days using a Completely Randomized Design (CRD) with 5 treatments and 2 replications. Treatments consisted of A (100% pellets), B (25% silkworm flour + 75% pellets), C (50% silkworm flour + 50% pellets), D (75% silkworm flour + 25% pellets), and E (85% silkworm flour + 15% pellets). The parameters observed in this study included absolute weight growth, specific daily growth (SGR), survival rate, and water quality. The results of this study indicate that treatment E produced the highest absolute weight gain (18.45 g), significantly different (p<0.05) compared to other treatments. The survival rate of the study reached 100% in all treatments. Water quality measurements during the study were within the optimal range for milkfish growth. Therefore, the combination of 85% silkworm meal and 15% pellets is the best feed to increase milkfish growth without affecting its survival.

Abstract

Milkfish (Chanos chanos) is an economically important aquaculture commodity, while Ulva intestinalis is a nutrient-rich macroalga with potential as an alternative feed ingredient. This study examined the effects of U. intestinalis-based feed on milkfish growth, survival, and feed efficiency. A 60-day experiment was conducted in Mbay, Nagekeo Regency, East Nusa Tenggara, using a completely randomized design with three treatments and three replicates. The feeds contained 25% (A), 30% (B), or 45% (C) U. intestinalis. Absolute weight gain, specific growth rate, survival rate, feed conversion ratio, temperature, and pH were evaluated. Dietary U. intestinalis significantly affected absolute weight gain and feed conversion ratio (P < 0.05). Treatment A produced the highest weight gain of 14.37 g, followed by B at 14.01 g and C at 13.92 g. Survival was 100% in all treatments. The best feed conversion ratio occurred in C at 1.39, followed by B at 1.42 and A at 1.46. Water temperature ranged from 27–29°C and pH from 7–9. Thus, 25% U. intestinalis produced the best growth response.
