It's complicated First of all, whether the fish pond is a hotel investment or your investment is related to the pricing of seafood.

Then there is the cost of fish ponds: water and electricity, fish medicine, fish food, filtering consumables and so on.

Mainly the maintenance of refrigeration equipment. If the refrigeration equipment is invested by you, the dead fish is of course yours. If it is invested by the hotel, it will be in big trouble.

Generally, the contractor will quote every 7 days or 10 days. After that, the sales director will report the price to the general manager for approval, and then sell it at the marked price. However, contracting fish ponds is very profitable. Although the hotel is stuck, there are many doorways to make big money!
