I'm not sure what type of market exists for such 
devices, but there are already electronic units 
currently available which lets one rapidly record fish 
lengths and then download the data into a computer for 
storage and analysis...very similar to the digital 
calipers currently available.

We collect lots of this sort of data. We try computer methods every now 
and then and always come back to the good old measuring board for 
recording lengths and put this data into a computer from the paper copy. 
The problem is that most sophisticated measuring units fall to bits on a 
trawler in the North Sea in a gale, or are too big to install on anything 
but a research vessel (A new french boat has a system I believe) 

Now If anyone came up with a good system we'd jump at it. We might even 
help to develop one if you asked nicely :-)
