Fish Handling

Introduction

Different techniques should be used by the handler to minimise damage to the fish and to themselves when handling fish.

All work with fish that involves manual handling should be carefully planned out to ensure that all stress is minimised and only essential procedures are performed quickly and efficiently.

Importance for the fish

Fish are very easily stressed by handling and changes in their environment. Fish should not be chased or frightened before handling, and handling time should be minimised to ensure minimal impact on the fish's health.

It is important to wear latex gloves during manual handling of fish, as fish skin is not keratinised and is susceptible to iatrogenic damage. Any material in contact with the fish should be wet and minimally abrasive. Equipment such as paper towels are not appropriate. Abrasive material removes the protective layer of mucus on the fish's skin and can lead to skin damage.

Latex gloves are soft and slippery when wet which is an ideal handling surface for fish.

If samples are being taken it is important to rinse the gloves before using them during sample collection as talc crystals may contaminate the biopsies.

Fish should be protected from temperature fluctuations and oxygen depletion during handling. Exposure to sunlight or excessive heat can be damaging to most fish. The gills should be kept wet at all times, and this allows a considerable amount of time for examination out of the water.

Importance for the handler

Gloves are also important for the handler as they minimise the risk of infection with zoonotic diseases potentially carried by fish.

Certain fish may be dangerous to handle by one person alone and an assistant may be necessary to ensure the safety of all involved.

Eye protection can be worn by the handler to protect from splashing water and any damage to the eyes.
