Loach, or the weather loach as it is commonly known, is a freshwater fish found in the rivers and wetlands of Asia, Africa, and Europe.
Loaches are bottom-dwellers and resemble eels in appearance, with elongated, slimy bodies. Adult loaches can weigh between 1-2kg, with a dark grey back that fades to a lighter shade on their bellies.
Loaches feed on insects that live on the water’s surface, as well as aquatic creatures such as small shrimp and mollusks. They are primarily nocturnal and inhabit higher river sections or brackish marshes near the coast.

2 How to Select Fresh and Meaty Loach
Tips for selecting fresh and meaty loach
To ensure you’re getting the freshest loach, it’s best to purchase from a specialized seafood market or a live seafood store.
When choosing loach, select those that are still alive and vigorously wriggling, with a sizable body. Look for clear eyes, shiny skin, and bright red gills.
Avoid loaches that appear lifeless or immobile, as this could affect the quality and taste of the fish.
Also, steer clear of very small or skinny loaches, as they tend to have less meat and more bones.
