Ilish is the National Fish of Bangladesh
The species is overfished now. It is becoming rare to land 3 or 2 kg specimens. There have been consequent price increases and collapsing populations. In the past ilish were not harvested between Vijaya Dashami and Saraswati Pujadue to some informal customs of Odia and Bengali Hindus as it is the time when the juvenile fish born upstream make their way to the sea during that period. But as disposable incomes grew, wealthier consumers abandoned the old traditions. The paradox is that increasing prices have led to even more over fishing. The advent of finer fishing netsand advanced trawling techniques, and environmental degradation of the rivers, has worsened the situation. Fishermen have been ignoring calls to at least leave the juvenile "jatka" alone to repopulate the species. The fishing of the young jatka is now illegal in many countries. It is thought that some 83,000 seasonal fishermen are employed in catching them and traders are bidding up the price of the fish to exorbitant levels. Furthermore, the changes brought about by global warming have led to a gradual depletion of the ilish's breeding grounds, reducing populations further. The fish is heading towards extinction in certain regions.[
Ilish is the National Fish of Bangladesh. In many Bengali Hindu families a pair of ilish fishes (Bengali: Joda Ilish) are bought on auspicious days, for example for special prayers or puja days like for the Hindu Goddess of music, art and knowledge Saraswati Puja, which takes place in the beginning of Spring or on the day of Lakshmi Puja (The Goddess of Wealth and Prosperity) which takes place in autumn. Some people offer the fish to the goddess Lakshmi, without which the Puja is sometimes thought to be incomplete. In Bengal Ilish is also used during wedding as tattwa gift. During Gaye Holud tattwa the family of the groom presents a pair of Ilish to the family of the bride. However, due to the scarcity of Ilish, nowadays it is often replaced by Rohu in West Bengal, while the tradition continues in Bangladesh.
In West Bengal, a famous dish which tastes good with fried ilish fish is 'khichudi' (a special way of cooking lentils and rice together with some added herbs). It is popular among all Bengalis during monsoon which is known as the month of ilish. In West Bengal and Bangladesh, ilish is often termed as the 'queen' of fishes.
