I've been looking for data for a fishing app that I'm trying to make but I can't seem to find what I'm looking for. I've contacted the California DFG and it was a long wait for nothing. So would be awesome if the Bass Resource guys could help me out!

 

Here's what I'm looking for:

 

Bass length, height, girth, weight, and ideally a picture of this fish but it's OK if there isn't one. 

 

If anyone knows where I can find this, or even if you have your own catch log that you wouldn't mind sharing with me, I will be forever in your debt.

 

Thanks guys!

What is your goal regarding using this data for an app?

I want to find a correlation between the length, height, and weight.

this has already been done

Bass weight = Length^2 x Girth^2 / 1200

Is this for a school project? Are your required to collect your own data?

 

If not there several charts available online with scatterplot detail.

Bass weight = Length^2 x Girth^2 / 1200

In-fisherman magazine has written on this subject several times over the years.  From what I recall, the formula works well on average fish, not as well on above average fish.  In-fisherman went so far as to vary the formula for different species, walleye, pike, muskie, perch, etc.

Before you re-invent the wheel - contact In-fisherman about this subject.

Google fish weight calculator. If you go in the tools dropdown on BR there is a calculator

There are plenty of on-line calculators you can find from a google search.

Length = bass laying on a flat surface, mouth closed and measure from tip of closed low jaw to the center of the tail.

Girth = measurement around with widest area! dorsal fin down.

Formula: L x L x G / 1200 = weight in pounds! accurate within 5%.

There are more accurate formulas, however require several girth measurements and accuracy becomes more subjective to the measurement technique to determine true mass.

Thanks for the replies everyone.

 

I'm aware of the Bass weight = Length^2 x Girth^2 / 1200 formula as I did bust out my google-fu for this before we got started . So even though there is a formula for this already, I'd like to see if there were some new insights that we could pull out, which would take a large set of data.

Thanks for this! I'll be inquiring about their data
