Write short note Physical factors and fishing.

Answer»

Development of fishing requires specific physical factors.

Therefore, it is developed on a commercial scale where physical factors are favourable for fishing.

The following are the important physical factors, which can be responsible for the development of fishing.

  • Broad continental shelf, with shallow water is favourable. 
  • For example, continental shelf along the eastern coastline of Japan is broad and water is shallow.
  • Warm and cold ocean currents should meet near the coastline, so that plankton (favourite fish food) is available in plenty.
  • Broken coast line which provides natural ports and harbours.
  • Cold climate is favourable for natural preservation of fish.
  • Since above all physical factors are present on the north-east coast of USA, north western coastline of Europe as well as in Japan, commercial fishing is well developed.
