Fisheries Stock Assessment: an inductive science with the Logical form of Primitive Magic
(2010-01-20)Abstract. A logical analysis of the common fisheries models used in stock assessment has shown that they produce specific predictions with the logical form of existential statements, fail Karl Popper’s falsifiability ... -
Can we stop the lobster going the way of the cod?
(labeled ‘A brief submitted in 2006 to the Fisheries Resource Conservation Council (FRCC)’, 2006)This report is a response to the Fisheries Resource Conservation Council (FRCC)’s request for opinion on how to reduce risk and address problems in Atlantic Canada’s lobster fishery. See www.frcc-ccrh.ca for further details ... -
Karl Popper’s organon and the world’s fisheries: fish stock assessment as a pseudoscience, an inductivism that can bear no fruit
(2006)Recent long term historical studies of commercial fisheries have pointed to a well established pattern of overfishing. Under the principle of transference – what is true in logic is true in psychology and scientific method ... -
Why an ecosystem approach is the wrong paradigm for the next stage of fisheries management
(2006-09-13)Scientists from the Department of Fisheries and Oceans (DFO) manage groundfish stocks by collecting biomass measurements that are used to provide scientific advice on catch limits. Clearly, if the data is uncertain or ... -
Scientific parameterization and its validation: comparing the universal models of fisheries economics with the invalid modeling of stock assessment
(2008-09-22)Here I compare the valid parameterization of fisheries economics with the data-fitted parameters of a stock assessment’s modeling, invalid models whose predictions cannot be falsified (which is another way of saying ... -

The Poverty of mathematical and existential truth: examples from fisheries science
(2011-06-27)Several years ago I suggested that the harvesting of our commercial fisheries could be improved if the non-falsifiable models of a fisheries science were to be replaced with the falsiable models of a fisheries economics. ... -

Farms as ecosystems
(University Extension Press, University of Saskatchewan, Saskatoon, 1999)Organic farming provides ecosystem services as well as food. The weakest points of organic farming systems are limited use of livestock and declining genetic resources. Organic farming has special research and service ... -
Systems for sustainable agriculture: approaches, tradeoffs and needs
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan, 2001)All systems of agriculture practiced today can be seen as having a potential for improvement and contributing toward a more sustainable agriculture.
