The effect of ethanolic extracts Ulva lactuca on growth performance and survival rate of milk fish (Chanos chanos)

Ulva lactuca is an algae that is a source of protein for fish and can increase resistance to disease.

Description
Summary:Ulva lactuca is an algae that is a source of protein for fish and can increase resistance to disease. The purpose of this study was to determine the effect of ethanolic extracts Ulva lactuca on growth and survival rate of milkfish (Chanos chanos). This research was conducted at Brackish Water Aquaculture Development Center, Ujung Batee, Aceh, Indonesia on April-March 2019. Data were analyzed using a completely randomized design with 6 treatments and 4 replication, namely A (0 ppm), B (100 ppm), C (200 ppm), D (300 ppm), E (400 ppm), F (500 ppm). The parameters measured were absolute weight growth, absolute length growth, specific growth rate, survival rate and water quality. The ANOVA test results showed that the Ulva lactuca extract had a significant effect (P0.05) on the survival rate of milkfish (Chanos chanos). The concentration of 500 ppm extract Ulva lactuca (treatment F) produced the highest on absolute weight growth (1.52 g), absolute length growth (1.96 mm), specific growth rate (0.30 %/day), and survival rate (96%).
