For these types of tasks, classic fish weighing sacks are sufficient:

"Sling" Carp Sacks

A sling carp sack is typically also equipped with floats and a zipper. This allows for temporarily retaining the fish in the sack for better photo opportunities or to organize a photo area during solo sessions.

There is an abundance of carp weighing and retaining sacks available on the market, with every manufacturer offering them. However, they differ in size, shape, and quality of craftsmanship. The most important structural element of a sack to pay attention to is its bottom, which is either flat or rounded.

Sacks with a Rounded Bottom

Sacks with a rounded bottom significantly increase the safety of the fish during weighing because they stabilize the fish and prevent it from sliding inside.

Below are examples of sacks with a rounded bottom:

Sacks with a Flat Bottom

Sacks with a flat bottom increase the risk of the fish sliding towards the tail, which can lead to scale or fin damage. These types of sacks are definitely better for retaining fish rather than weighing them.

Below are examples of sacks with a flat bottom:

The size of the sack is also very important, and it's definitely worth getting larger versions of at least 110 cm in length.

Many people assume that since they don't catch very large fish, why do they need such a large sack? But what if a fish longer than 110 cm is caught and the sack turns out to be too small? Nowadays, fish in Poland are truly impressive in size, and it's better to be prepared for anything by ensuring maximum safety for the fish.

More innovative solutions are also available on the market that allow for the safe transferring, weighing, and storing of caught fish. It's worth paying attention to a novelty from Nash - Nash Failsafe Retainer Sling, which also allows for a safe photo session:

This is a sack that features innovative floats in the form of a floating frame, allowing for a secure photographic session in the water. Such a solution makes it much easier to remove the fish from the sack for a photo and also with much less risk to return it when it starts moving vigorously.

The choice of sack is therefore strongly dependent on the fishing venues where you will be fishing. Even if you can't retain fish in sacks at a particular venue, it's still worth investing in a sack with that option, which provides an opportunity to prepare a photo area and allows the fish a temporary rest in the water, rather than on the bank. A sack with floats and a zipper is undoubtedly the most versatile and safest option of all.
