The research was conducted in Tarus Village (Manikin Beach), Kupang Tengah District, Kupang Regency. The location of this research was determined by considering that the waters in Kupang Regency, especially Tarus Village (Manikin Beach). The treatments tested were the provision of different types of feed, Treatment A: Feeding snails, Treatment B: Feeding mangrove shells, Treatment C: Feeding trash fish (tembang fish), Treatment D: Feeding chicken stomachs. The parameters measured in this study were absolute weight, daily weight and survival. Based on the research and research results the provision of different feeds significantly affected growth, both weight, but did not affect survival and the best feed for growth was shown in treatment A with the use of snail feed which resulted in absolute weight growth of 29.00 g, daily growth of 0.48 g% / h. While for survival reached 100% all treatments.

PERBANDINGAN TUBIFEX SP DAN CHIRONOMUS SP DALAM PAKAN TERHADAP PENINGKATAN WARNA IKAN KOMET (Carassius auratus) COMPARISON OF TUBIFEX SP AND CHIRONOMUS SP ON INCREASING THE COLOR OF COMET FISH (Carassius auratus)

A 30-day nutritional experiment was conducted at the Aquaculture Research Laboratory, Faculty of Fisheries and Marine Sciences. The study employed a Completely Randomized Design (CRD) with three experimental diets: (A) exclusive Tubifex sp. meal, (B) equal combination of Tubifex sp. and Chironomus sp. meals (1:1 ratio), and (C) exclusive Chironomus sp. meal, each replicated three times. Key performance indicators including skin pigmentation intensity, body weight gain, and linear growth were measured in goldfish (Carassius auratus). Statistical analysis revealed significant dietary effects (p<0.05) on all measured parameters. The blended diet (Treatment B) demonstrated superior efficacy, producing both the most vibrant coloration and maximal growth metrics among test groups. These findings suggest that balanced inclusion of both worm meals synergistically enhances ornamental quality and growth performance in this commercially valuable fish species.

The research was carried out for 3 months starting from April to July 2024, at two different locations, namely Motadikin waters and Kletek waters, Central Malaka District, Malacca Regency. The parameters observed in this study were growth in absolute weight, absolute length, survival and water quality. Comparison of the growth and survival of blood cockles can be seen that the highest growth in absolute weight and absolute length is found in Kletek waters and the lowest in Motadikin waters.

This research was carried out at BBIP Tablolong, Kupang Regency for 60 days. The aim of this research was to determine the effect of feeding snails (Achatina fulica) on the growth of white snapper (Lates calcarifer). The design used was RAL with 4 treatments and 3 repetitions, namely (A) f999 pellets 5% of the biomass weight (control), (B) snails 5% of the biomass weight, (C) snails 10% of the biomass weight, (D) snails 15% of the biomass weight. The parameters measured in this study are Absolute Weight Growth, SGR, SR, FCR, Feed Efficiency. The research results prove that treatment (B) Snails 5% of biomass weight is the best dose for the growth of white snapper with an absolute weight growth rate of 8.3 g, SGR reaching 0.048%g/day, SR of white snapper 90%, FCR 1.36 g, and feed efficiency value reaching 73.44%.
