World Fisheries Day is on November 21, celebrating fishing and promoting ecosystem health. Minecraft has launched fishing packs on its Marketplace, including an add-on that educates players about fish species and ocean pollution, featuring over 90 new fish and marine creatures. From now until January 29, 2026, all net proceeds from this add-on will support Conservation International's conservation efforts. The MobBlocks add-on offers a peaceful fishing experience with 70 new fish, while an advanced add-on introduces 40 new fish with realistic behaviors. The AutoFisher tool allows for easier fishing. Beginning September 26, 2025, Microsoft will contribute 100% of net proceeds from the add-on sales to Conservation International, along with a 0,000 contribution.
