- •
We combined a bioeconomic model and a life cycle assessment.
- •
We estimated the environmental impacts of genetic improvement in fish farming.
- •
Improving growth keeps environmental impacts constant in nitrogen limiting condition.
- •
Improving feed conversion ratio always decreases environmental impacts.
- •
We observed that decreasing environmental impacts could increase farm profitability.
