Implications of the 1981 Georges Bank and Gulf of Maine Cod and Haddock Assessments for Future Management Strategies

A Coupled Individual-Based Trophodynamics and Circulation Model for Studies of Larval Cod and Haddock on Georges Bank

This year, 1994, marks the 80th anniversary of the publication of a landmark paper in the study of marine fish population dynamics. In 1914, Hjort outlined two of the dominant hypotheses that continue to guide research into the causes of fluctuations in fish populations: 1) recruitment variability is governed by food-limitation of the larval stages; and, 2) recruitment variability is regulated ...

Genetic differentiation among Atlantic cod (Gadus morhua) from Browns Bank, Georges Bank, and Nantucket Shoals

The Atlantic cod (Gadus morhua) is a migratory gadid found on both sides of the North Atlantic. In the Northwest Atlantic, cod are distributed nearly continuously along the continental shelf from Greenland to North Carolina, spawning in relatively discrete, temporally stable areas, and different regions are regarded as different management units defined primarily by latitude and bathymetry (Ruz...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Feeding habits of Chaoboridae larvae in a tropical Brazilian reservoir.

The diet of the four larval instars of a Chaoboridae species of Lake Monte Alegre, was evaluated through the analysis of the crop content of individuals caught at night in the lake. Peridinium and zooflagellates were the major components of the diet of instars I and II, whereas microcrustaceans, especially the cladoceran Bosmina, were most important for late instars. When the preferential prey ...
