The impact of blockading is often significant enough to justify sizeable home fleets for defence. The most vulnerable end of the trading route is a faction's home trade ports as it prevents all trade from arriving, especially early in the game when they may only have one trade port. Blockading a port does not prevent naval recruitment, but if the port is unoccupied and your forces raid this will damage the facility and prevent recruitment.

However, unlike commerce raiding no income is earned by the blockading. Blockading a trade port prevent all trade through the port so it is very effective, and if the port is unoccupied it is raided and damaged.
