SPAROS has just released ficoEst | fish composition estimator, a new free web-based tool that estimates the body composition of farmed fish given information about fish weight, water and/or ash content. ficoEst is aimed at researchers who carry out studies in fish nutrition and fish farmers who wish to expand the information collected in the field.
ficoEst uses different mathematical models to estimate the body composition of fish, depending on the input data provided. Some models only use fish weight as input, while others use either fish weight, water and ash content. Providing more input data considerably improves the capacity of this tool to estimate the body composition of fish. However, knowing that the user does not always have access all information, we decided to implement different estimation methods to ensure that we are delivering a flexible and user-friendly tool that can be useful in a wide variety of situations. It is the user who chooses which model inputs to consider based on the best information available at the time.
Currently, ficoEst is available for 6 fish species:
- Gilthead seabream (Sparus aurata)
- Rainbow trout (Oncorhynchus mykiss)
- Nile tilapia (Oreochromis niloticus)
- European seabass (Dicentrarchus labrax)
- Atlantic salmon (Salmo salar)
- Meagre (Argyrosomus regius)
A manuscript describing the estimation methods behind ficoEst is being prepared for submission to a peer-review journal.
ficoEst was developed in the context of the FICA project and it is freely available at:
