The sound management of a fishery as a social engineering: applying Karl Popper's demarcation criterion to an Area 2 stock of Pacific halibut
The Newfoundland fishery for Atlantic cod was once the largest cod fishery in the World. In the early 1990s this fishery formed part of an Atlantic Canadian groundfish fishery collapse that has become one of the World's ...
Some notes on the Aristotelian origin of the distinction between a falsificationist's and verificationist's view of science: together with corrections to my earlier account
It has not always been realised that Karl Popper's analytic distinction between the logically stronger falsificationist's view of science and the logically weaker verificationist's and inductivist's view of science is a ...
The Poverty of mathematical and existential truth: examples from fisheries science
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. ...
Observations on a mixed farm during the transition to biological husbandry
Tunwath is a mixed farm (laying hens-grains) located in the Annapolis Valley, Nova Scotia, in a cool humid temperate zone. It includes about 2100 laying hens, 35 hectares of field crops and additional garden, pasture, hay ...
Fisheries Stock Assessment: an inductive science with the Logical form of Primitive Magic
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 ...
Distinguishing input controls from ouput controls in Atlantic Canada's fisheries: explaining the decline and collapse of Newfoundland's Atlantic cod stocks
The lobster and groundfish fisheries of Atlantic Canada have been managed in very different ways. The Atlantic lobster fishery has been managed by input controls in which regulations have been developed by a posteriori ...
Reduced Retinal Function in the Absence of Na(v)1.6
Background: Mice with a function-blocking mutation in the Scn8a gene that encodes Na(v)1.6, a voltage-gated sodium channel (VGSC) isoform normally found in several types of retinal neurons, have previously been found to ...

The relationship between offspring size and fitness: integrating theory and empiricism
How parents divide the energy available for reproduction between size and number of offspring has a profound effect on parental reproductive success. Theory indicates that the relationship between offspring size and ...
Historical changes in genotypic frequencies at the Pantophysin locus in Atlantic cod (Gadus morhua) in Icelandic waters: evidence of fisheries-induced selection?
The intense fishing mortality imposed on Atlantic cod in Icelandic waters during recent decades has resulted in marked changes in stock abundance, as well as in age and size composition. Using a molecular marker known to ...
