A bioregional classification of the continental shelf of northeastern North America for conservation analysis and planning based on representation [PDF]

open access: yes, 2007
Understanding how well National Marine Sanctuaries and other marine protected areas represent the diversity of species present within and among the biogeographic regions where they occur is essential for assessing their conservation value and ...

Feed for Atlantic cod

open access: yes, 2006
Today the cost of feed is 50-60% of the total production of farmed cod. A 10% reduction in feed cost will therefore give a minimum of 5% reduction in production cost. The biggest single variable cost in cod farming, the high cost of feed, is the main obstacle in making cod farming economically feasible.

Economic impacts on key Barents Sea fisheries arising from changes in the strength of the Atlantic thermohaline circulation [PDF]

open access: yes
A bioeconomic model of key fisheries of the Barents Sea is run with scenarios generated by an earth system model of intermediate complexity to assess how the Barents Sea fisheries of cod (Gadus morhua) and capelin (Mallotus villosus) are affected by ...

Male Agonistic Behavior on Atlantic Cod Spawning Grounds

open access: yesEcology and Evolution
The mating system of the iconic Atlantic cod (Gadus morhua) has been described as a lek, a mating system where male–male agonistic interactions are expected. However, observing such behaviors directly in marine environments is challenging.

Demographic change and fisheries dependence in the northern Atlantic [PDF]

open access: yes, 1998
Northern Atlantic fisheries have experienced a series of environmental shifts in recent decades, involving collapse or large fluctuations of the dominant fish assemblages. Over roughly the same period, many fisheries-dependent human communities have lost
