Moisture Sensor for Fish/Food

Hello sir, good day! I am working on a project solar drying of fish. Is there any moisture sensor for this?? i have to automate the gathering of moisture content in arduino. As of now, i have no code because i am still searching for a sensor for my problem. Thank You.

Many humidity sensors are not accurate. I suggest to buy a soil moisture sensor. http://www.adafruit.com/products/1298
