When it comes to carp fishing, proper fish care is paramount to ensure the well-being of the fish during and after the catch. One of the essential best practices is the use of a specialized mat, commonly referred to as an unhooking mat, when placing the carp down. This mat acts as a protective barrier between the fish and the ground, cushioning the carp's body from any hard or abrasive surfaces such as rocks and gravel that can cause injuries to its scales and mucus membrane. It's crucial to keep the mat and the fish wet, which helps in maintaining the protective slime coat on the carp's body, vital for its health once returned to the water.

Weighing the fish is a practice many anglers enjoy to document their catch, but it must be done correctly to avoid harm. Instead of suspending the carp by its mouth or gills, which can lead to significant damage and stress, anglers should use a proper weigh sling. This sling is designed to support the fish's weight evenly and allows for a safe and accurate reading. Furthermore, the weigh sling can double as a means to gently transport the fish back to the water, reducing the risk of dropping or mishandling the carp during the release process.

Lastly, the technique of holding a carp is crucial for its protection. Anglers should always place one hand under the pectoral fins and the other under the anal fins to give adequate support. This method avoids undue pressure on any single part of the carp's body, which is particularly important for larger, heavier fish. It's also important never to hold carp by the gills, as this can cause irreparable damage to their delicate gill filaments, leading to potential respiratory problems. By following these guidelines, anglers can enjoy their sport while ensuring the carp are returned to their habitat unharmed, promoting sustainable fishing practices.
