Calculated as the ratio of the feed given to the weight gain of the animals, it is expressed as follows: � . � . � . = � � � � � � � � � � � � � � � � � � � ℎ � � � � � F . C . R . = A nima l w e i g h t g ain F ee d g i v e n In simpler terms, FCR represents the quantity of feed required to produce a kilogram of fish. For instance, if one kilogram of fish necessitates two kilograms of feed for growth, the FCR would be 2. A lower FCR is indicative of higher feed quality, as it signifies that less feed is needed to produce a given amount of fish. Ammonia Testing Procedure: Determining the ammonia (NH3) level in aquaculture involves a three-step process: Measure pH and Temperature:
