Moonfish: A Unique Delicacy of the Ocean

Moonfish, scientifically known as *Mene maculata*, are a type of fish that inhabits the Indian and Pacific Oceans. They are famous for their distinctive shape and distribution range. 

Morphological characteristics: The moonfish has a laterally compressed, thin, and high body, resembling a spectacle lens. Adults typically range in length from 10 to 20 centimeters and weigh between 75 and 200 grams. Their abdomen is significantly curved, with a convex and thin ventral margin and a slightly curved back, hence their name. Their scales are very small, almost invisible, but can be felt by hand. Their mouth is small, vertical, retractable, and tilts upwards like a tube.

The anal fin is positioned low with a relatively long base, and in adults it is mostly buried under the skin. The caudal peduncle is short and laterally compressed, and the caudal fin is deeply forked with the upper and lower lobes of equal length. The pelvic fins are small, but two of them are particularly long. The upper part of the body is dark blue, the lower part is silvery-white, and the pectoral fins are light yellow. There are two to three rows of black round spots smaller than the eye diameter above and below the lateral line.

Distribution and Season: Moonfish are distributed in the Indian and Pacific Oceans. In my country, they are mainly found in the South China Sea and East China Sea, with the South China Sea yielding the largest catch. The fishing season along the coasts of Hainan and Guangdong typically runs from April to July.

Economic Value: Moonfish are relatively abundant and have considerable economic value. Their flesh is similar to that of pomfret, and they can be prepared in various ways, commonly steamed or fried. 

Moonfish are not only delicious but also a common marine creature, deserving our understanding and protection.
