Physical Characteristics of Indian Mackerel

Here are the notable physical attributes of Indian mackerel

Body Shape: Indian mackerel features an elongated, fusiform body shape. It is streamlined and designed for swift swimming through the water. This shape allows it to move efficiently and swiftly, enabling it to be an agile predator.

Size: The average size of Indian mackerel ranges from 20 to 35 centimetres in length, although it can grow up to 45 centimetres in exceptional cases. The size may vary depending on factors such as age, habitat, and availability of food.

Colouration: Indian mackerel exhibits an intriguing colour pattern. The upper part of its body, also known as the dorsal side, has a deep blue-green colour. As we move towards the sides and belly, the colour transitions to silver. This gradient helps the fish blend with its surroundings, providing camouflage and protection from predators.

Stripes: One of the most distinctive features of Indian mackerel is the presence of dark, wavy stripes on its upper body. These stripes run vertically across the fish, starting from the back and extending towards the belly. The stripes serve as a visual marker, aiding in species recognition and identification.

Scales: Indian mackerel has small, overlapping scales covering its body. These scales are smooth to the touch and offer protection against friction and potential injuries. The scales also contribute to the fish’s streamlined shape, reducing drag as it moves through the water.

Fins: Like other fish species, the Indian mackerel possesses various fins that aid in its locomotion and manoeuvrability. It has a dorsal fin located on its back, which helps maintain stability during swimming. The anal fin, positioned closer to the tail, assists in steering and balance. Additionally, Indian mackerel has pectoral fins on the sides, pelvic fins near the abdomen, and a caudal fin (tail fin) that provides propulsion.

Overall, the Indian mackerel showcases a sleek, vibrant appearance characterized by its elongated shape, distinctive colouration, wavy stripes, and a set of fins that enable its remarkable swimming capabilities. These physical characteristics contribute to both its visual appeal and its ability to thrive in the oceanic environment.

2. Cleaning and Gutting: If you buy whole Indian mackerel, start by cleaning and gutting the fish. Rinse it under cold water and remove the scales using a scaler or the back of a knife. Make a shallow cut along the belly and remove the innards. Rinse the fish again to remove any remaining blood or impurities.

3. Marinating: Indian mackerel pairs well with marinades and spices. Marinating the fish before cooking enhances its flavour.

Bake for approximately 15-20 minutes or until the fish is cooked through and flakes easily. You can add sliced lemon or herbs like dill or parsley for extra flavour.

6. Curry Preparations: Indian mackerel is commonly used in curries, adding a rich and flavorful element to the dish. Use a combination of spices like cumin, coriander, turmeric, and chilli powder to create a fragrant curry base. Add coconut milk, tomatoes, onions, and other vegetables or ingredients of your choice. Simmer the fish in the curry until it is cooked and absorbs the flavours of the sauce.

7. Pairing: Indian mackerel goes well with a variety of sides and accompaniments. Serve it with steamed rice, naan bread, or crusty bread to soak up the flavorful juices. Fresh salads, pickles, chutneys, or a squeeze of lemon can complement the fish’s taste.
