Fishing

Fishing can alter the shoaling behaviour of fish, with ecological and socio-economic consequences

Fishing activity may decrease the shoaling behaviour of fish, a strategy they use to minimise the risk of predation, acquire resources and share information efficiently, according to an international study led by ICM-CSIC and CREAF.

Humans use more phosphorus to produce fish than we obtain by harvesting them

There is an imbalance between the amount of phosphorus we use in the production of fish and shellfish (which need it for growth, bones and shells) and the amount we obtain by harvesting them. Remedying it will require aquaculture’s mean phosphorus use efficiency to increase from its current level of 20% to 48% by 2050.
