This is why you should avoid farmed fish...

The reasons for avoiding farmed fish from many regions aside. I don't see using an excavator as one of them.
I helped engineer a small-scale commercial fish farm experiment on the Danube in Romania, by creating an artificial isolated wetland along the delta. to filter the pollutants out of the incoming water to the ponds for raising sturgeon. the idea was to produce not only caviar, and to grow hatchlings into fingerlings for restocking and fully matured fish for marketing. 2 by-products were to be fertilizer and nutrient rich water for large scale greenhouse irrigation. I had even helped my retiring QAQC inspector secure startup funding from a couple of Kuwaiti sheiks. But I don't know hao he made out since I Retired and left Kuwait shortly after, before ever being able to go to Romania again.
