Biology help on efficient energy transfer in fish farms?
In the sea cages the salmon are fed on pellets that are made from other fish. The nutrients in the pellets are more concentrated than in the fish they come from. The cages also make it easier to treat the salmon for parasitic infections, which are more common than in the wild because of the density of fish in the cages..
Salmon get energy from their food, and we get energy when we eat salmon. Energy is lost from an orgasism due to repiration. What do salmon use the energy released in respiration for?
Explain why confining the salmon in cages should help them grow faster?
Two reasons why salmon fed on pellets grow faster than salmon in the wild?
In terms of energy loss, explain why treating caged salmon for infections helps them grow faster?

Confinement limits the use of food as ‘energy’ per se, and converts more readily to growth (meat).
Confinement fed salmon do not have to swim far to get daily food, thereby conserving energy.
As for treating caged salmon for infections, with less energy lost to fighting infections, salmon can put on weight faster. Any food they consume then does not have to be used to heal itself, but can be converted to growing cells/putting on weight.
