This policy is unlocked after an Algae Farm is built and Milestone 5 is reached. When Algae-based Water Filtering is enabled, the water service network uses algae as a natural filtering system. Sustainable and Dolphin-safe Fishing both unlock at Milestone 6.
This increases citizen happiness but also lowers the fish yield.
With the Dolphin-safe Fishing policy, the fishing industry adopts new techniques to ensure minimal dolphin fatalities resulting from fishing. This increases the price of fish sold but lowers the fish yield, as fishing boats leave more fish in the ocean to minimize the environmental impact. With the Sustainable Fishing policy, the fishing industry can take steps to ensure that the fish population sizes stay at healthy levels. The policy unlocks at Milestone 3, and it increases crime and decreases citizen happiness by a small amount.
The Fishing license policy creates residential tax income from the city selling affordable fishing licenses to its citizens. Sunset Harbor also includes 6 new policies, four of which are fishing related.
