How do you measure your catch?
There are many ways to measure your catch fishing. You can use a ruler to measure the length of the fish, or you can use a scale to weigh the fish. You can also use a tape measure to measure the girth of the fish.
Definition of Term for measuring your catch
The length of a fish measured from the tip of the snout to the posterior end of the middle caudal rays. This measurement is used instead of standard length for fishes on which it is difficult to ascertain the end of the vertebral column, and instead of total length in fish with stiff, forked tails.
Total length
- Standard length ( SL ) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the mediolateral part of the hypural plate. Simply put, this measurement excludes the length of the caudal (caudal) fin.
- Total length ( TL ) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. This is a rectilinear measurement that does not measure your catch along the curve of the body.
- Fork length ( FL ) is the length of a fish measured from the tip of the snout to the end of the middle rays of the caudal fin and is used on fish where it is difficult to tell where the spine ends
- Spring-loaded Retractable ruler for easy storage
- Oversized, easy-to-read numbers, in 1/2″ Increments up to 60″
- Non-reflective surface ensures the length shows
1. Place the fish on its side with the jaw closed.

2. For soft-tailed fish, squeeze the tail fin together to obtain the maximum overall length.

If you unintentionally take a fish (including fin fish or crustaceans) that is not the legal size or is unwanted, return it to the water immediately, taking as much care as possible to avoid causing injury to the fish.
Other measurements to measure your catch
Other measurements that can be taken include the lengths of various fins, the lengths of the fin bases, the length from the snout to various points on the body, and the diameter of the eye.

Fish scale to Measure your catch

Great scales and a great price, the measuring tape is not really something I’d use but it is a good added bonus, my only grumble is as I use the scales for fishing when it comes to using pounds it’s just that pounds and not pounds, and ounces, so will read10.5 pounds rather than 10 pounds 7 ounces, but other than that can’t fault them.
Conclusion
The most important thing when measuring your catch is to be as accurate as possible. There are a few different ways to measure your catch, but the most common method is to use a measuring tape. Measuring your catch with a tape measure is the best way to ensure that you are getting an accurate measurement.
