Introduction A paper published in 1898 by the Freidrich Heincke, a German fisheries biologist, influenced biologists to consider the population as the unit of study instead of the species. Insights from the Heincke’s paper helped to cultivate the influential quantitative methodology to distinguish marine fish populations. The application of statistical methods and quantification techniques in marine biology contributed to the generation of an enormous amount of knowledge related to fisheries. The shift of fishery biologists, Zoologists and wildlife agencies towards numbers and measurement in their research methodology, shaped modern Fisheries Science and contributed to solving some of the critical problems associated with fisheries. In 1957, a model published by Beverton and Holt enabled scientists to predict the future size and yields of fish stock. This quantitative bio–economic model allowed governments to make decisions on the most optimal fishing levels to help reach biological and economic goals ( Bavington, D.L.Y. 2009). Cod fishery management systems in Canada incorporated Heincken’s population approach and bio-economic system models of the 1950’s to calculate the total allowable catch. An official report that was the basis for Canada’s Cod fisheries management strategy, tremendously overestimated northern Cod populations. To correct this error in 1990, the Harris report recommended the reduction of “Total allowable Catch” from 235, 000 to 190, 000 tonnes. In 1992,
