Abstract

On the west coast of India, the mackerel Rastrelliger kanagurta (Cuvier) is reported to enter the lower reaches of the Kali river at Karwar in April and May, when the salinity of the river water is between 29.73 and 34.60%o (Pradhan, 1956). In the Netravati at Mangalore a fishery of small magnitude, extending as fer as 6 miles up the river, was observed during the January-March period in 1958
