Trout weight by length

[wtretrievers]

Can't go by that chart.
W is 4'8" & outweighs me by 50lbs & I'm 5'8"

The above graph shows weight vs. length of spotted sea trout measured by colleagues and I from Big Lake in 2011 and 2012. The blue line is the best fit line which produces the weights in the table below. Note that there are no measured fish longer than 27", so the table might be less accurate for longer fish. 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

Oh, yeah, some of the fish in the graph were even caught by "W".

Did you figure in the months that these were caught? Male vs female?

These charts are more indicative of Big Lake trout than Lake Pontchartrain.

The spotted seatrout in our study were not sexed and were all caught between June 9 and June 15 (both in 2011 and 2012). The graph below is based on a much larger data set from the Louisiana Department of Wildlife and Fisheries. It shows only a small difference between weights of males and females in spring in Louisiana, and also little difference between spring and fall, with spring fish being slightly heavier at a given length.
