Bill, I posted the link for SRAC 201. In particular, I linked it because it had guidelines for density as a proportion of fish weight to water weight. Grams per liter is parts per thousand and the fact sheet cited a density of 5 to 8 grams per liter. An equivalent in cubic feet would be .3 to .5 lbs per ft^3. Don't know it applies to larger fish ... but at the lower density, 6 11" LMB would require ~12 cu feet. So a 2x2x3 cage may be appropriate for the OP. Below is an excerpt on recommended weight density (recommended for feed training 2" fingerlings).
