Carp (Cyprinus carpio) is a freshwater fishery commodity that has significant economic value and high development prospects. This species is widely cultivated due to increasing market demand, thus offering great opportunities for development in intensive and semi-intensive cultivation systems. This study used a completely randomized design (CRD) with 3 treatments and 3 replicates. The parameters measured included survival rate (SR) and growth. Survival rate data were statistically analyzed at a predetermined significance level and followed by a BNT test according to the Steel and Torrie method. The results showed that the administration of spurge extract (Euphorbia hirta L.) did not have a significant effect on the survival rate of carp (Cyprinus carpio). The administration of spurge extract (Euphorbia hirta L.) at a concentration of 12.5 mg/L resulted in an average value of 80%. In comparison, the administration of a 25 mg/L concentration of Euphorbia hirta L. extract resulted in an average value of 93.33%. The administration of 37.5 mg/L of Euphorbia hirta L. extract resulted in an average value of 86.66%. Based on this presentation, it can be said that Euphorbia hirta L. extract affects the survival of carp (Cyprinus carpio).

Budikdamber has emerged as a practical food-production strategy for urban areas with limited land resources, making it necessary to examine how stocking density influences the growth performance and survival of African catfish (Clarias gariepinus) cultured under this system. This study was conducted from June to August 2024 at the Aquaculture Field Laboratory, Universitas Nusa Cendana. The experiment employed a completely randomized design (CRD) consisting of three treatments with three replicates each: A (20 fish per container), B (30 fish per container), and C (40 fish per container). The evaluated parameters included survival rate, weight gain, and absolute length growth. The statistical analysis indicated that stocking density had a significant effect on survival (P<0.05), with treatment A achieving the highest survival rate of 100%. In contrast, no significant differences were detected for weight and length growth among treatments (P>0,05), although lower densities tended to support slightly better growth. Overall, the budikdamber system maintained stable water quality and supported satisfactory fish performance when stocking density was managed appropriately.

Efektivitas Rotasi Pemberian Cacing Sutra Kering (Tubifex sp.) dan Pakan Komersil terhadap Pertumbuhan Ikan Mas (Cyprinus carpio)

Goldfish (Cyprinus carpio) as a high-economic aquaculture commodity requires appropriate cultivation techniques to meet market demand. Feed management as the main key to successful cultivation remains a problem for farmers, including goldfish farmers. The use of commercial feed requires quite high costs so that farmers use alternative feed to increase the protein content of the feed. Silkworms (Tubifex sp.) are known as a natural feed that is widely used because they are high in protein and economical. This study aims to determine the effect of the rotation of natural feed silkworms (Tubifex sp.) and commercial feed (pellets). The research design used was a Completely Randomized Design (CRD) with 4 different treatments, namely, A (Pellet 30 days-silkworms the next 30 days), B (silkworms 30 days - pellets the next 30 days), C (Silkworms 60 days), D (Pellet 60 days) with a treatment duration of 2 periods of 60 days. The data obtained were analyzed using the LSD test. The best treatment from the research results was obtained in treatment D (60-day pellets) with absolute weight growth (2.53 gr) and the highest survival rate was obtained in treatment C (60-day silk worm feed), namely 93.3%.
