Table 4. Environmental Value (ENV) of TGC (thermal growth coefficient) at fish and farm level in different quota.
Qprod is the quota on annual production, Qannual_feed is on annual feed distributed, Qstock is on the daily biomass present on site and Qdaily_feed is on daily feed distributed. Between brackets is the percentage a change in environmental impacts. A negative sign means that the environmental impact considered increased after genetic change.
