of War and the Fish

The experiments on fishery are hard to conduct. One of them is the study on how protected area from fisheries relevant to the fish population. The fisheries biologists have conducted kinds of this research in tropics area, in Great Barrier Reef in Australia, but to have a solid evident, they need to conduct a research in the temperate-zone, in the area of North Atlantic.

One day the opportunity was come, 71 years ago, the Second World War was happen and it made the North Sea area close unintentionally, and the group of biologists led by Doug Beare, at the European Commission’s Office of Maritime Affairs, grabbed this golden event to study its effect on the population of cod, haddock, and whitting.

Provided information by Britain’s Ministry of Agriculture and Fisheries from Buchan, Beare knows that during the WWII, from 1928 to 1958, the fishing in North Sea was eventually decrease, thereafter, there was no such activity in 1939; Accordingly, Beare have a questions on how much the decreasing in fishing affect to number of the fish.

In Naturwissenschaften, Dr Beare tells us that the population of the fish has decrease steadily before 1939, but after the fishermen have stop fishing in the area, the number of older haddock is increase, although, the number of younger haddock is decrease. His teams propose the theory that because the older haddock fed with the younger, as a result, the younger population decline.

In 1945, there was hostilities ceased, then the population of the fish continue to decline as it were before the WWII; however, the population of the fish was boom in 1955, which is remain an unknown reason. Nevertheless, Beare has his question answered, the decrease in fisheries really have an effect to the number of the fish as same as the result in the Great Barrier Reef.
