How to measure and photograph large fish for proof of length
« on: February 05, 2012, 09:38:43 am »
Last year I was struggling to measure and photograph large Stripers so as I could enter them in the AOTY. I return 99% of my fish and the most important thing is to get them back in the water quickly, because of this I gave up trying to measure/photo them and just roughly guessed, but of course that wont count for the AOTY. The main problem is getting the camera high enough so as to get all of the fish in the frame while keeping the fish flat on the measure, you really do need another set of hands haha. Hero shots are no problem, just geeting shots to proove length.

If only I had that problem  ;D is the measure on the paddle handle no good ? you could lay this on your lap with the fish. I dont have the answer to the photo problem thou

I have seen a 4 inch PVC sewer pipe with cap on one end, run through a band saw to open it up. It had a 36 inch Rapala ruler sticker slapped on the inside. The pipe cradled the fish (still have to keep them from flopping around) and it is rigid enough to lay over the cockpit or your lap. I think it was about three feet long - bit of a pain to store on board.

I use a folding Rapala ruler, but because the ends stretch over the lip on my cockpit (sit-in boat) the ruler dips down into the center slightly. This makes my measurements slightly shorther than the actual fish - not good for tournaments. This year I will end up with some for of rigid support under the ruler to stop the bending.

Hope that helps,
Alan

For longer fish I had to hold the camera straight above the fish ( your eye isn't on the viewfinder ).
My arm with the camera would be fully extended, and at least you have one hand free to try to hold the fish in place.
With some practise this isn't hard to do, just point the lens straight down and snap a few pics.
Also a tethered lip gripper is a great tool to use. I often had the fish swimming beside yak with gripper in its mouth while using my hands to review pics, then release fish.
Also with a lipper you can tow fish to shore  if it isn't too far away..probably a problem offshore saltwater fishing eh?   :)
A sandy beach and in the water is better for bigger fish than thrashing about in the cock pit of a yak.
I like the 48" board I made, but yes some curvature ( cradling ) would help sooth fish.
Even a towel ( wet it first ! ) under the board would help in some situations ( striper... ;))

yup, getting propper pic`s of big stripers in a kayak isn`t easy, and as you said Paul, it`s even harder if you are releasing them. i use a fish grip to control the fish and as often as not, i take the fish into the shallows or shore to take the picture. 90% of the time stripers i`m releasing don`t get their pictures taken.
with my kayak i can support the fish and measure with my legs but i found that if i can support the measure with my paddle, even just resting the edge of the measure along the paddle, you get a cleaner measure and the fish doesn`t flip as much. i then hold the camera up as far as i can, take the shot blind, then give him a drink while i check the photo.
i`m thinking a camera pole and a remote might be the way to go. or maybe a fish eye lens.

my bump board measures 36", which really is short for stripers and sturgeon, so i`m looking at doing the pvc thing, maybe a folding one that would measure out to 6`? i can hope anyway. lol!

I made a PVC one for the tourney last year.Worked better than anything else I've tried.Easy to make too.I would definitely use  4'' PVC like Alan said.3'' is too narrow.

i'm thinking 6", stripers are heavy.

6'' would be better for the Bigger fish but you'd have to go to a wholesaler for it and they don't typically sell short pieces so you'd be into a length.Maybe make a few and split costs or something.

I seem to recall someone had a measuring board of some sorts, but he also had a couple of straps (elastic or velcro - either would probably work).  He placed the fish on the measuring board then fastened the straps.  It held the fish in place better - but I don't know if it hurt the fish much.  I'm guessing it might be easier on the fish than flopping around the cockpit of the kayak.

Hmmm, I think that's something I might build.

Hey BobD here's link for the board I made with velcro straps.

I think using the straps on coarse ( tough ) fish such as carp and gar is okay, but would NOT use them for say muskie nor trout.

sweet.  thanks.

I bet I could use it on a sturgeon that I'm going to catch this year.  :)

Wal-mart has collapsing bump boards that are decent enough. I'm thinking they're 48" when extended. They wouldn't cradle a fish near as well as a 4" or 6" piece of PVC pipe but with the velcro straps on them I'm sure they would work for a decent sized fish. I don't even carry mine half the time because it's a pain to carry around and store on the boat, and it's only 2 feet long when collapsed. Might be something to consider if you're going to build a 4 foot long bump board.

the walmart one is the bump board i have now. i like it, it`s 36" and for 99% of fish it`s more than you need.
for big fish, take it in to shore to take the photo if you can. so long as the yak is in the shot. they know you can`t get that measurment shot any other way with the really big ones.. at the smallie slam they said to get out and take the picture from shore with the fish on the measure on the yak for that tourney. not always a perfect catch and release but still way better than taking it in at the end of the day to a weigh in.

when you can`t get in  to shore in time to safely release the fish, taking multipule shots, a close up of the head and tail position and then some video has been my method of choice. so far when i have done it, i have then landed bigger fish closer to shore, so i ended up culling the open water shots, so i don`t know if they would be okay yet.

i`m thinking of using an extending pole for the camera, and using the program function to take 3 quick shots. so long as the striper stays polite, it should be okay... ::) 8)

Having a buddy here helps you a lot.  I have a 5' cloth measuring tape glued to the side of my kayak.  I could get a pretty decent idea of it's actual length by pulling it up alongside the kayak.  A buddy could also take a picture while I'm holding it there.

As for the tournaments, I'm thinking this is an example of where cooperation between participants, and a sense of fair play, can come in handy.
