Abstract

Freshwater prawn (Macrobrachium rosenbergii) is a freshwater species which intensively cultivated. Calcium (Ca) and magnesium (Mg) are crucial factors supporting the biological and physiological activities of freshwater prawns. The presence of calcium and magnesium minerals in the environment is utilized by the prawns, especially after the molting process. Calcium and magnesium play roles in osmoregulation and the formation of the prawn's carapace. This study aims to determine the optimal ratio of calcium and magnesium minerals to support molting frequency, specific growth rate, survival rate, and feed efficiency.The experimental design used in this research is a completely randomized design (CRD) with five treatments and three replicates. The treatment given consisted of increasing Ca-Mg in the media: A: 30 mg l-1 Ca + 0 mg l-1 Mg (1:0); B: 30 mg l-1 Ca + 15 mg l-1 Mg (1:0.5); C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1); D: 30 mg l-1 Ca + 45 mg l-1 Mg (1:1.5) and E: 30 mg l-1 Ca + 60 mg l-1 Mg (1:2). Based on the result, treatment C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1) was found to improve molting frequency, growth rate, feed efficiency and survival rate.

Abstract

Color enhancement in ornamental fish is an essential quality parameter that directly influences market value and consumer preference. Natural pigments derived from marine resources, such as seaweed, offer a sustainable alternative to synthetic color enhancers. This study aimed to determine the effect of seaweed meal (Eucheuma cottonii) on the color brightness of goldfish (Carassius auratus). Goldfish used had an initial weight of 10.12 ± 0.06 g and an initial length of 5.08 ± 0.02 cm. Fish were fed using the ad libitum method three times daily with four feed treatments: P1 (Control), P2 (4 g seaweed meal), P3 (8 g seaweed meal), and P4 (12 g seaweed meal). The study was conducted for 45 days to evaluate growth performance and color characteristics. A completely randomized design with four treatments and three replications was applied. Data were analyzed using one-way ANOVA at a 95% confidence level (p < 0.05). Results showed that the addition of seaweed meal significantly influenced the red hue variable in goldfish. Brightness showed no significant difference among treatments, with the highest value in P4 (55.88%) and the lowest in P3 (52.68%). The red hue differed significantly, with the highest value in P3 (16.96%) and the lowest in P1 (9.13%). The yellow hue showed no significant difference, with values ranging from 36.68% (P1) to 38.43% (P2). Overall, supplementation with 8 g of seaweed meal effectively enhanced the visual red hue of goldfish.

Abstract

Feed stability is a crucial factor in aquaculture, as it affects both the physical integrity of the feed and its acceptance by aquatic species. For Monopterus albus (swamp eel), maintaining feed stability while ensuring palatability is vital for optimal growth and health. This study aimed to evaluate the effects of different binder types and concentrations on the stability and acceptability of pasta feed for Monopterus albus (swamp eel). Seven binders—gelatin, gluten, CMC, chitosan, alginate, guargum, and carrageenan—were tested at 0%, 10%, 15%, and 20% concentrations using a completely randomized design. Feed disintegration and breakdown times, along with feeding behavior, were analyzed using non-parametric tests. Gelatin, CMC, and chitosan significantly improved feed stability (p < 0.05), maintaining cohesion for over 40 minutes. Gelatin at 10% concentration yielded optimal results, balancing water resistance and palatability. Behavioral observations showed that gelatin-based feeds were most preferred, with increased feeding frequency and consumption. When combined with natural attractants such as worms and snails, gelatin feeds enhanced intake rates. These outcomes indicate that protein-based binders, particularly gelatin, offer superior mechanical and nutritional advantages compared to polysaccharide alternatives. Gelatin’s dual role as a binder and nutritional enhancer provides a promising strategy for sustainable aquaculture feed development.

Abstract

Kegiatan pengabdian masyarakat ini berfokus pada penerapan teknologi aerasi microbubble venturi untuk mengatasi permasalahan utama budidaya ikan nila di Kelompok Pembudidaya Ikan (Pokdakan) Tunas Karya, Kecamatan Lingsar, Lombok Barat. Permasalahan tersebut adalah rendahnya kadar oksigen terlarut (DO = 2-3 mg/L) dalam kolam yang menyebabkan tingkat kematian ikan tinggi (18%) dan efisiensi pakan rendah (FCR 1.8). Metode kegiatan meliputi sosialisasi, pelatihan teknis, instalasi alat, serta pendampingan dan evaluasi berkala. Hasilnya menunjukkan peningkatan signifikan kadar DO menjadi 5-6 mg/L. Dampak lanjutannya adalah penurunan mortalitas di bawah 7%, peningkatan efisiensi pakan (FCR 1.4), dan pertumbuhan biomassa yang lebih baik. Selain aspek teknis, kegiatan ini juga berhasil meningkatkan kapasitas SDM kelompok melalui pelatihan dan pembentukan tim teknis internal untuk menjamin keberlanjutan. Disimpulkan bahwa teknologi aerasi microbubble venturi efektif meningkatkan produktivitas dan ekonomi budidaya ikan nila. Oleh karena itu, replikasi teknologi ini kepada kelompok pembudidaya lain sangat disarankan.

Abstract

Light spectrum plays a crucial role in photosynthesis and biomass development of marine macroalgae. This study aimed to evaluate the effects of different light spectra on biomass development of Caulerpa lentillifera in controlled cultivation systems. Four LED light treatments (white, red, yellow, and green spectra at 3000 lux intensity) were applied using a completely randomized design with three replications over 30 days. Growth parameters including absolute growth, relative growth, specific growth rate (SGR), and biomass residue were measured at 10-day intervals. Results showed that red light produced the highest absolute growth (0.107±0.004 mg), relative growth (2.39±0.15%), and SGR (0.237±0.015% day⁻¹), followed by white light (0.101±0.015 mg, 2.26±0.34%, 0.224±0.034% day⁻¹). All treatments exhibited biphasic growth patterns with peak biomass on day 10, followed by progressive decline. White light maintained the highest biomass residue (64.4±23.3%), while green light showed the lowest performance across all parameters (39.3±3.7%). The superior growth under red light is attributed to optimal absorption by photosystem II at 680 nm wavelength. This study recommends red light for maximizing short-term biomass production and white light for maintaining long-term stability in C. lentillifera cultivation systems.
