Here's why it's tricky to say:
* Different species: "Sea trout" can refer to various species, including brown trout that migrate to saltwater, rainbow trout, and others.
* Lack of official record: Unlike some fish species, there isn't a widely recognized international organization that maintains official records for sea trout catches.
* Variable catch methods: Different fishing methods (fly fishing, spinning, trolling) can lead to variations in size and weight of fish caught.
* Unreported catches: Many anglers may not report their catches, making it hard to know the true size of the largest sea trout ever caught.
If you are looking for a specific region's record: You can search for records within particular fishing clubs or organizations in specific regions. You can also consult with local tackle shops or experienced anglers.
Remember: It's important to practice catch and release to protect fish populations and ensure future fishing opportunities.
