Hi Vivek,

There are many sectors under which one can work after completing diploma in fisheries. The main areas are discussed below:

Farm management: This area contains tasks like site selection, construction of ponds, monitoring, feeding, maintaining water quality, selective stocking, and hazard analysis.

Hatchery Management: In this area work consists of stock collection, feeding, rearing, spawning in artificial conditions, larvae stage, oxygen packing, transportation to the farms etc. It is an important area as there is shortage of manpower in our country in this field because Aquaculture is new in our country. Companies have to recruit people from foreign countries.

Harvesting and Processing Management: It is also important because in this area products are prepared for exports after harvesting and due to slackness may lead to high loss.

Fishery Inspector: Job of a fishery inspector is to transport fishes from one fishery station to another fishery station.

Fishery Worker: They are responsible for catching, breeding and cultivating. There are some private as well as public sector companies that perform task of breeding, cultivation and management of fishes. Most of the companies reside near coastline.

Research: This field deals with development of new and better variety of fishes. Many research projects are done by Indian Council of Agriculture Research.
