How much does a dog fish weigh?


Recommended Posts

My brother and I caught two one was 26 and 1/2 inches and then the other was 27 inches. Both were very chucky just wondering what you guys think the weight might be? I have no idea where or how to guess. Thanks guys.

I lost one this walleye opener looked like 30inches or larger maybe state record cause I think MN state record is 11.4oz Man them babies fight

Got this info from a bowfin HSOforum

Using empirical data we obtained and MS Excel Regression analysis, the best formula we have for estimating the weight of a bowfin is G^2*L/780 +0.75 = W, where G is the girth (circumference) in inches, L is the length in inches, and W is the weight in pounds. The prediction factor is 0.96, with 0 meaning the formula doesn't predict the data at all and 1 is a perfect prediction, so we are very close with this formula.The values in Table 1 were calculated with this. The girths we found in our dataset, expressed as a fraction of the length ranged from a low of .42*L to a high of .57*L so I restricted my table to these limits.

If you have length only, the average girth is 0.492*L making the formula L^3/3221 + 0.75 = W. The prediction factor drops to 0.90, still pretty good and enough to let you know if you are near a state/class/world record that merits special attention. See Table 2 for these values.

a bowfin with an average girth that is 26 1/2" Long would weigh on average about 6.5 lbs. a 27"er with an average girth would weigh about 6.9 lbs.

but if you had the girth i could get a more accurate weight. a 26.5" can weigh anywhere from 4.9lbs to 8.2lbs, depending on the girth. a 27" can weigh anywhere from 4.9 lbs to 8.5lbs
