9.2.1.3 Socio- economic impacts
The socio-economic impact can be seen at two levels (i) capture fisheries and (ii) aquaculture. Since the exotic fishes never fetch higher price than the native varieties and also the decline of native fish production is observed in presence of exotic species in natural waters, the total economic return declines for the stakeholders of the capture fisheries. In aquaculture, however it provides immediate gain in most cases without considerations of long term ecological sequences.
