Fertilizer costs, diesel fuel costs, herbicide costs. All inputs the farmers have to look at. If they can't turn even a small profit on what they plant, what is the sense of planting? Equipment operation costs, parts for the equipment, etc., etc. all comes into play.

It all depends on where in the USA you are too, for fuel/gas prices. Here in Indiana, I've seen $3.60/gal gas and $4.05/gal diesel. Today in Arkansas and Missouri I saw gas for $2.99/gal and diesel for $3.29/gal. A friend in Oklahoma said gas is $2.89, diesel is $2.89 and if you buy at the co-op diesel is $2.75.

Delivering fish getting 10-12 mpg @ $4/gallon is a lot different than delivering fish at $2.99/gal. Especially when you have to figure in a 1,500 mile round trip just to pick up the fish before you start deliveries.
