The changing nature of marine fisheries requires management approaches that recognize and include ecosystem and environmental effects. Therefore, we review some examples of exploited fishery stocks in which environmental control is a major contributor to structuring the abundance and distribution of the stock. Four examples, taken from studies of northern cod (Gadus morhua), cod and haddock (Me...

This chapter provides a general overview of the Barents Sea demersal trawl fishery. First, it reviews historical catch levels and current biomass status of four commercially important demersal species (cod, haddock, Greenland halibut, and redfish) and includes an overview of their management plan that has been carried out by the Joint Norwegian–Russian commission. Then, it presents the evolutio...

THE RESEARCH ARTICLE "IMPACTS OF BIODIVERSITY LOSS ON OCEAN ECOSYSTEM SERVICES" BY B. Worm et al. (3 Nov. 2006, p. 787) projects that 100% of seafood-producing species stocks will collapse by 2048. The projection is inaccurate and overly pessimistic. Worm et al. define "collapse" as occurring when the current year's catch is <10% of the highest observed in a stock's time series. However, fish c...

I argue against the interpretation of propositions as intentions and proof-objects fulfillments proposed by Heyting defended Tieszen van Atten. The idea is already a frequent target criticisms regarding incompatibility Brouwer’s Husserl’s positions, mainly Rosado Haddock Hill. raise stronger objection in this paper. My claim that even if we grant can be properly dealt with, Atten believes it ca...
