Feed management is one of the determinants of the success of vannamei shrimp farming. To know about this efficiency, we must first calculate the vannamei shrimp FCR.
FCR or feed conversion ratio, is the result of calculating the effectiveness and efficiency of the stocked feed. Through FCR calculations, you can find out whether the feed given is actually eaten by the shrimp or is left over and becomes a waste.
In Indonesian, FCR is also known as rasio konversi pakan, which can indicate the level of efficiency of feed management in every cultivation that is carried out. The smaller the FCR number, the more efficient the feed management is.
Therefore, let’s learn what FCR is and how to calculate it below.
What is Vannamei Shrimp FCR?
Feed conversion ratio or FCR is the calculation of the total weight of artificial feed divided by the cultivation’s total weight (biomass). In vannamei shrimp, the ideal FCR value ranges from 1.1-1.2. The smaller the FCR value obtained, the greater the profit obtained by the farmers.
Not only vannamei shrimp but FCR also applies to other aquaculture commodities, such as catfish, salmon, etc. In contrast, the high or low FCR is determined by the type of feed, species, animal size, feeding practices, water conditions, and the run culture system.
The Importance of FCR in Vannamei Shrimp Cultivation
The feed conversion ratio (FCR) is an essential metric in vannamei shrimp farming because it can provide information about the feed’s efficiency during cultivation.
The low number of vannamei shrimp FCR indicates that the feed given to vannamei shrimp is well absorbed and makes cultivation more profitable from an economic and sustainability point of view.
Conversely, a high FCR indicates that the feed is inefficient and can lead to increased costs and lower profits for the farmer. In addition, a high FCR number also harms the environment, especially in terms of water pollution.
How to Calculate Vannamei Shrimp FCR
To calculate FCR in vannamei shrimp farming, you must first determine the amount of feed given to the shrimp and then measure the weight gain of the shrimp over a certain period.
FCR is then calculated by dividing the feed given to the shrimp by the increase in shrimp biomass. The Feed Conversion Ratio (FCR) formula is as follows:
For example, the shrimp biomass that you cultivate is 1 ton (1000 kg). While the amount of feed that has been given is 1.2 tons (1200 kg). Then the FCR of vannamei shrimp is 1200: 1000 = 1.2.
