Why do fish sellers often use black bags?

Have you ever noticed that fish sellers tend to use black plastic bags? There are several reasons for this practice.

Firstly, black bags prevent people from seeing the contents inside, including any blood or mess from the fish, which may be off-putting to some customers.

Secondly, these bags are usually thicker and more durable, reducing the need for double-bagging and saving costs. Lastly, the black bag can enhance the appearance of the fish, making the colors appear more vibrant and appealing to buyers, especially for brightly-colored species.

Tips for choosing fresh fish

Eyes

Fresh fish will have clear, dark eyes that are slightly bulging. If the eyes are cloudy, pink, or sunken, the fish is likely old and spoiled.

Flesh

To test the freshness of the fish, gently press your finger on its flesh. If the fish is fresh, the flesh should quickly spring back. If your finger leaves an indent, the fish is not at its best.

Gills

The gills of fresh fish will be bright red or pink. If they appear dull or dark, the fish is not fresh.

Skin and Scales

Look for fish with tight, shiny scales and clear skin free from any spots or marks.

Frequently asked questions

Fish sellers often use black bags to keep the fish cool and fresh. The black color absorbs heat from the sun, creating a cooling effect inside the bag, thus acting as a natural cooler.

The black bag absorbs the sun’s heat, preventing it from penetrating the bag and warming the interior. This creates a cooler temperature inside the bag, helping to preserve the fish.

Yes, the use of black bags can also help to reduce the growth of bacteria and microorganisms. The dark environment created by the black bag inhibits bacterial growth, thus extending the shelf life of the fish.

While the use of black bags for fish is a simple and effective method, it is not commonly practiced. Many fish sellers are unaware of this technique, and some may prefer to use ice or other traditional cooling methods.

One potential drawback is that the black bags can get quite hot when exposed to direct sunlight for extended periods. This may defeat the purpose of using them as a cooling method. Therefore, it is essential to store the black bags in a shaded area or cover them to prevent excessive heat absorption.
