Why should fish be fresh?

I was asked recently why fish should be fresh!! Here is my answer:
The freshness of fish is crucial for several reasons, mainly related to flavour, nutritional value and food safety. Here are some key reasons why it’s important for fish to be fresh:
Quality and Flavor: Fresh fish generally has a firmer texture, moistness, and a better flavour compared to older or improperly handled fish. The degradation of fish quality begins soon after the fish is caught, and factors such as length of supply chain, temperature, storage conditions, and handling practices significantly affect taste and texture.
Nutritional Value: Fish is a valuable source of essential nutrients, such as omega-3 fatty acids, protein, vitamins, and minerals. The nutritional content of fish starts to decline as soon as it is caught due to enzymatic and bacterial activities. Consuming fresh fish ensures that you get the maximum nutritional benefits.
Texture and Appearance: Fresh fish has a vibrant appearance, and a distinct smell of the ocean. As fish age, the flesh will become dull and slimy, and the odor may turn unpleasant. These changes can affect the overall dining experience.
Cooking Performance: Fresh fish cooks more evenly and retains its natural juices, resulting in a more enjoyable and flavorful meal. The texture and moisture content of the fish contribute to the success of various cooking methods, such as grilling, baking, or frying.
Sustainability: Consuming fresh fish promotes sustainable fishing practices. It encourages responsible harvesting and discourages the wastefulness associated with discarding fish that are no longer suitable for consumption.
Food Safety: Fresh fish is less likely to harbor harmful bacteria, parasites, or pathogens that can cause foodborne illnesses. As fish age, the risk of bacterial growth increases, leading to potential health hazards for consumers.
To ensure the freshness of fish, it’s essential to purchase it from reputable sources, with as short a supply chian as possible, it must be stored properly at the right temperature, and consume it within a short period. Proper handling and adherence to food safety guidelines contribute to a positive culinary experience and support sustainable fishing practices.
