Description The recent increases in the catch of mackerel from the deeper waters of the Calicut - Cochin area indicate that the fish move down to deeper areas during summer due to the thermocline. Spreading of trawling to deeper waters, with the opening up of export market for cephalopods, can be the reason for the increased catch of mackerel by trawls. The most successful period of recruitment to the mackerel fishery coincides with upwelling (Mackerel form large shoals to feed on the plankton that is abundant due to upwelling, making surface fishery highly successful.) which guarantees abundance of stock during the period. Intensity of upwelling increases catchability and can result in a decline in spawning stock and recruitment. This can be one of the reasons for wide annual fluctuations in the catch of this resource.
