Topic: The charts show the different forms in which fish were sold in 1950 and 1985. Summarize the information by selecting and reporting the main features, and making comparisons where relevant.

The two pie charts depict the proportion of global fish sales by five different product categorises in the two years which are 1950 and 1985.

Generally, in comparion between 1950 and 1985, it can be seen that there was a drammatic increase in the total quantity of fish-related products sold worldwide of over 3.5 times, from 21 million tonnes in 1950 to 76 million tonnes in 1985. By the end of 1985, animal meal obtained the biggest proportion in global fish sales, while cured fish and frozen were the least-sold goods.

Fresh fish, which had occupied the largest proportion of 50% over total global fish sales in 1950, witnessed a considerable decline of 30% by 1985, followed by cured fish products with a decrease of 20%. In contrast, frozen fish exhibited the largest growth rate of 13 times, from 1% in 1950 to 13% in 1985. The percentage of animal meal and canned fish products sold, moreover, also soared remarkably to 32% and 22%, respectively.
