Fixed the invisible sturgeon bug in the Kiel Canal location.
Fixed the Eagle Eye bug caused by inaccurate main camera tracking, which rendered the fish ghost in the wrong position (most noticeable in the Kiel Canal).
Added an exhausted state for fish when stamina reaches 0, causing them to swim slowly and restricting pulling.
Added an Underwater Blur Effect option to the settings panel and linked it to Beautify DoF.
Applied hand power resistance only when pulling the rod upward with a hooked fish; the downward motion remains quick.
Turned off the underwater point light.
Dynamically set KWS transparency when switching to underwater mode to improve visibility.
Moved Water Graphics settings to a separate category in the settings panel.
