Survival Rate and Feed Conversion Ratio of Milkfish in Different Silvoaquaculture Ponds

Abstract

Silvoaquaculture is a model of brackish water ponds that combines aquaculture with mangrove conservation. This study examines aspects of feed conversion ratio (FCR) and survival rate (SR) as benchmarks for milkfish production that are maintained in three different types of silvoaquaculture ponds (Empang Parit, Komplangan, and Kao-kao Ponds). This research was conducted in Indramayu Residence (Indonesia). Data collected by questionnaires and determination of the respondents was done by purposive sampling with the aim of getting fish farmers in silvoaquaculture ponds. Data analysis uses a statistical test approach (ANOVA and DMRT). The milkfish that are cultivated in silvoaquaculture ponds have a survival rate ranging from 25.00%-80.00% with an average of 52.98%. Survival rate between types of silvoaquaculture ponds was different; Empang Parit ponds produce the lowest survival rate (average = 44.98%) and Kao-kao ponds have the highest survival rate (average = 59.64%). Mangroves become predatory animal habitats, so milkfish survival in silvoaquaculture ponds is low. The best feed conversion ratio of a Kao-kao pond is 1.63, followed by a Empang Parit of 1.82, and a Komplangan of 1.92. Feed conversion ratio between types of silvoaquaculture ponds was not significantly different. Mangrove ecosystems contribute to high nutrient waters, so natural food grows well and becomes additional feed for milkfish.
