    While starting an investigation on basic production off Cochin at the southwest coast of India, a section across the shelf with serial observations on temperature, salinity, and oxygen content was run in the last week of August 1958. The bottom water was observed to be very badly aerated, and from the hydrographic data it was inferred that these conditions were connected with upwelling. Berner and Schemainda (1957) have shown for the basins of the Baltic that at low oxygen figures the cod either migrates away or turns to midwater life so that bottom trawling becomes unprofitable. Therefore, it was thought worthwhile to investigate closely the upwelling and its effect on the catch of demersal fishes off Cochin.
