What type of gloves should be avoided while handling fish specimens?

Wool gloves should be avoided while handling fish specimens primarily due to their tendency to absorb moisture and create friction, which can lead to damage to the fish's skin and scales. The fibers of wool can also catch on delicate membranes, potentially causing harm to the fish during handling.

In contrast, vinyl, latex, and rubber gloves are designed for handling various materials, including biological specimens. They provide a smoother surface that reduces the likelihood of damage to the fish while providing a barrier to protect the handler. These materials are also easier to clean and sanitize, further contributing to safe handling practices in electrofishing procedures. Thus, choosing gloves made from synthetic or rubber materials is essential for both the safety of the fish and the efficacy of the sampling process.
