"The mutant terror of the sea..."
- 爆炸泡泡: Duke Fishron blows roughly 10-20 bubbles from his mouth that follow the player at moderate speed, exploding and dealing damage on contact. The bubbles can be destroyed by any attack or projectile. These inflict the Wet debuff for 3-8 seconds. Duke Fishron will either move to the top left or top right of the player's location before starting the attack. This attack is affected by wind. The Sharkron attack has the opposite direction of this attack, but it changes each time Duke Fishron is summoned.
- 鲨鱼龙：猪龙鱼公爵挥动他的鳍，召唤出液滴，它们会下落（穿过任何平台）直到穿过 1.5 倍屏幕垂直大小或撞到物块。随后它们生成鲨鱼旋风：巨大的水龙卷，每个都会射出几个鲨鱼龙。鲨鱼龙的飞行范围有限，在撞到物块时会被摧毁，并且可以被玩家杀死。
When Duke Fishron falls below 50% (25000 / 30000 / 38250) health, he remains stationary for a second and transforms, being a good time to deal damage and/or consume Potions. His skin becomes a darker green and his eyes will start glowing. His damage and speed increase significantly, but his defense is reduced to 40. His lunges become faster, and are only performed three times instead of five before executing one of his projectile attacks, which are also upgraded:
- There is now only one "blob" that causes a tornado, but it follows the player, creating a Cthulhunado on contact. Cthulhunadoes are significantly bigger than Sharknadoes and will spawn twice as many Sharkrons; they also deal double the damage of Sharknadoes.
When Duke Fishron falls below 15% (9000 / 11475) health, he will stop moving to transform again, and the background will be covered in a dark, blue fog. Duke Fishron will become invisible, but his eyes still glow. His damage will be reduced to 184 / 277, his defense will drop all the way to 0, and he will only attack by charging at the player, but he gains the ability to teleport behind them before doing so. 他的冲锋会以固定模式出现：
- Straying too far from the Ocean area (more than 400 tiles from the (unreachable) lateral edge of the world) during the fight causes Duke Fishron to "enrage", lunging at the player continuously, dealing double damage, and gaining double defense (similar to Plantera's "enraged" behavior outside the Underground Jungle). However, Duke Fishron will not enrage whatsoever on 前代主机版. Note that altitude also matters: If the player is below surface level, or within 50 tiles from the top of the map (due to part of the map being unreachable, this distance is around 13 tiles in-game), Duke Fishron will enrage. Also, note that Duke Fishron will not despawn because of the biome or time of day.
- 要留意当前你和 Boss 所生成的海洋之间的距离，避免他变得被激怒而让战斗不必要地变得更加困难。
- Duke Fishron's charges aim for where the player is, not where they will be. Because of this, moving perpendicularly with his charges will cause him to completely miss. Dodging his charges can be as simple as moving in a zig-zag pattern or a triangle.
- 他是唯一免疫错愕减益的 Boss，使得心箭在面对他时毫无用处。
- Using an 反重力钩 on a block and continuously going in circles can successfully allow dodging every attack and dash from the boss. Note that this only works when the boss is enraged.
- On 专家模式, the Shield of Cthulhu can be used to great effect, providing brief invincibility frames when dashing into him.
- Though its difficulty makes it a post-Plantera or Golem boss, it is possible to defeat him before the Mechanical bosses and obtain his weapons in order to make fighting the Mech Bosses incredibly easy. Using some basic weapons like the Crystal Serpent, Daedalus Stormbow with Holy Arrows, and the Golden Shower can make defeating him a bit easier and will make a good majority of Hardmode a lot easier to progress through.
- 猪龙鱼公爵原本是 Re-Logic 的愚人节笑话的一部分，他们声称有个“水族部落”事件要加入游戏中。只有猪龙鱼公爵这部分元素引入了游戏中。
- 在 Wii U 版中，第二阶段的眼睛只会在变换形态和召唤克苏鲁旋风时发光。
- 猪龙鱼公爵形象类似于美国动画科幻情景剧《飞出个未来（Futurama）》第四季第二集《Leela 的家园（Leela's Homeworld）》中出现的一只突变怪物。
- 鲨鱼旋风的攻击是对 2013 年美国科幻灾难电视电影《鲨龙卷（Sharknado）》的暗示。
- Duke Fishron drops an absurdly low amount of coins compared to other Hardmode bosses, despite being one of the toughest to defeat. This was changed with 22.214.171.124 - he now drops many more coins than before.
- 猪龙鱼公爵（以及扩展一下，可爱猪龙鱼）似乎是鲨鱼、猪、和龙的组合物。Cenx 证实了猪龙是后两者杂交形成的，这更进一步证实了这理论。
- 克苏鲁旋风可能是参考了克苏鲁的化身“所有鲨鱼之父（Father of All Sharks）”。
- 猪龙鱼公爵是唯一一个有三个不同阶段的 Boss，其中之一是专家模式独有的。
- Duke Fishron is the only Hardmode boss that does not have to be defeated to progress the game.
- Duke Fishron is one of 6 bosses with exclusive music, the others being Queen Bee, Queen Slime, Empress of Light, Plantera, and Moon Lord.
