1.	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.
