Boon, I notice the values for BG in the table as well.
At this point, I know of 4 sources for the energy density of BG. Kitchell 1974 is reported 4186 Joules/g wet. Kitchell wound up lumping many centrarchid fish together with the same energy density.
To be sure, there is a lot of variation in the literature and this is probably depends on growth rate, time of year, etc. Long story short, it hasn't been easy to pin down a single number and so to some degree I go with it tongue in cheek. Kitchell Reported 4186 J/g, when I converted Strange and Pelton 1.06 kcal/g to joules/g wet I get 4435 Joules/g wet. In the that second table it is reported 4661 Calories/g dry. This is 19501 Joules/g dry. They found the dry weight percentage to be 27.6 and so this equates to 5382 joules/g wet. Miranda found 1.16 kcal/g wet (4853 Joules/g wet). So...
Kitchell..........4186
Strange Et al ....4435
Table 1 ..........5382
Miranda ..........4853
It does seem to be variable.
For what it's worth, I estimated GAM at 6163 J/g wet and 23300 J/g dry from the proximate analysis. My first attempt was 5440 J/g wet but this was later changed given better information on the energy density of fish protein and lipids.
I wish I had better info on GSH, will be looking closer at Eric's reference above. I had no idea that GSH have dry weight proportions of lipid of 34.8%. That's on par with carp which has an energy density of 7524 J/g wet per Cummins and Wuycheck 1971. Kelso 1972, however, reports GSH wet density at 4983 J/g wet so that's what I work with presently
