In shrimp farming, one of the most common indicators used to measure success is the Feed Conversion Ratio (FCR). Many farmers and aquaculture practitioners see a 1:1 ratio meaning every 1 kg of feed produces 1 kg of shrimp as an impressive achievement. However, when examined more closely, this logic oversimplifies the complex biological and ecological processes happening in the pond.
This article explores why an FCR of 1:1 should not be viewed as the ultimate indicator of farming success, and what other factors need to be taken into account.
Why FCR 1:1 Is Not Always a Benchmark for Optimal Shrimp Growth
1. Water content in feed
When applying the 1:1 FCR concept, assuming 30 tons of feed would yield 30 tons of shrimp, not all nutrients in the feed are actually absorbed by the shrimp. Shrimp pellets typically contain around 9-10% moisture, meaning about 3 tons of that feed is just water, while the remaining 27 tons consist of dry matter composed of protein, fat, and carbohydrates.
