However, also note that of 247 fish measured, the trendline is within 1/2 lb for all of the 247 fish with the largest error being 0.427 lbs, so it is unlikely that a fish between 12" and 27" long would be more than 0.5 lbs different in weight from the table below. 91% of the fish measured were within 0.2 lbs of the trendline.


TL (in) Wt (lbs)
12 0.58
13 0.74
14 0.93
15 1.15
16 1.39
17 1.67
18 1.99
19 2.34
20 2.74
21 3.17
22 3.65
23 4.18
24 4.75
25 5.38
26 6.05
27 6.78
28 7.57
29 8.42
30 9.33
31 10.30
32 11.34
33 12.44
34 13.62
35 14.87

I def believe the 27" 6-8 bc I've seen 5-7 27" fish and all went 7or right at it and none went 8.
