The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
This species is caught and sold as a food fish. Because of its market value it is studied for its potential as a farmed fish in the aquaculture industry. It is easy to rear in captivity, it can be raised on fish food rather than live prey, and it has a good feed conversion ratio, efficiently turning feed into meat. [8]
These higher protein-level requirements are a consequence of the higher feed efficiency of aquatic animals (higher feed conversion ratio [FCR], that is, kg of feed per kg of animal produced). Fish such as salmon have an FCR around 1.1 kg of feed per kg of salmon [11] whereas chickens are in the 2.5 kg of feed per kg of chicken range. Fish do ...
The feed consists of protein-rich defatted biomass of Nannochloropsis oculata and whole cells of DHA-rich Schizochytrium sp. and was found to perform better in growth, weight gain, specific growth rate, best feed conversion ratio and fish nutrient content than the reference diet of ocean-derived fishmeal and fish oil.

This fish grows rapidly and has a high feed conversion rate. Over 50% of the total aquaculture production of carp in China has now converted to Jian carp ...
In the beginning, breeding programs focused mainly on growth traits. Nowadays, more traits are included in the breeding goal. The tendency is to have even more traits in the future. For example, disease resistance, reproductive traits, robustness, lower emissions, feed conversion ratio (sustainability traits).
The food vs. feed competition is the competition for resources, such as land, between growing crops for human consumption and growing crops for animals. [1] [2]In many countries, livestock graze from the land which mostly cannot be used for growing human-edible crops, as seen by the fact that there is three times as much agricultural land [3] as arable land.
