FACTORS OF FISHING

Q5. HIGHLIGHT THE FACTORS OF FISHING.

OR

WHY ARE THE FISHING GROUNDS DIFFERENT IN DIFFERENT COUNTRIES? EXPLAIN.

OR

WHICH FACTORS HELPS IN PROMOTING FISHING? DISCUSS.

ANSWER:

There are two basic factors which divided the fishing grounds at the global Level: physical and economic.

 

a. PHYSICAL FACTORS:

The following physical factor helps or impedes fishing a success or a failure:

 

1. SHALLOW COASTAL AREAS:

Plankton, the food of fish is found in abundance in the shallow waters. Fish can’t survive without this food. Plankton is brought by rivers casting into the ocean. This is the reason that the shallow waters of ocean are the best fishing grounds because small fish live on plankton and the small fish are the food for big fish.

 

2. PROPERTIES OF WATER:

The flow and the depth water and the temperature influence growth of fish. If flow of water is hampered, some kinds of plankton are gathered which provide food to fish clue to which fish grow fast.


3. CLIMATE:

Fishing is promoted in the cold countries and the regions. Fish live in flocks therefore, cost of fish hunting falls and they could be supplied to the market according to the programme. On the contrary, fish do not live in flocks in the hot countries due to which one time netting provide mixed catch and so their grading according to the kind becomes expensive. The fish found in the hot regions have not only lesser proportion of caught in the cold areas consists on one kind and are caught in abundance. Consequently, the cost of catch decreases. Moreover, the catch can be kept preserved or a long time in the cold regions.

Fishing grounds on the high lands are covered with the forests and vegetation therefore, packing of fish and the wood for making hunting boats is available in abundance.

 

4. CURRENT MIXED:

In some of the seas cold and warm currents are mixed together. These currents bring different sea vegetation and plankton with them with becomes the ideal food for fish. For instance, near the Grand Coast, cold and warm Surf streams are mixed together. Similarly, near the Japanese coasts, Cord Kama Chitka and Wards Japanese currents are mixed. Despite this, fish hunting becomes difficult in these regions due to ice burgs thick mist because the fishing trollers and boats can’t be operated in these areas.

 

5 UP WELLING:

The fast winds blowing from coasts, dragging water, creates a vacuum and water comes fast from the bottom to fill this vacuum. This circular flow of water or Up Welling brings insects and plankton from the bottom of sea which is used by fish as food. This Up Welling can prominently be seen in seas ofPeru,Californiaand Chili.

 

b. ECONOMIC FACTORS:

Fishing is also adopted as occupation due to some economic factors. For instance, for the people living in some regions no occupation is available except fishing therefore, fishing is promoted in these areas due to economic reasons.

Following are the important economic factors:

 

1. Pattern of fishing organization.

2. Supply of food stuffs and the price of the food items having proteins.

3. Better and promptly available banking facilities.

4. Size of the local population and the international demand for fish.

5. Availability of fast and modem means of transport.

6. Facilities of technical training for the fishermen.

7. Sufficient cold storage facilities for preserving fish.

8. Orthodox religious and social sentiments.
