Deterministic Population Dynamics of Fish Stocks at Low Population Sizes: A Parametric Spline Approach

Creator:

Maroto, Jose M. and Moran, Manuel

Abstract:

We develop a methodological approach using splines to analyze the deterministic population dynamics of fish stocks at low stock levels. Considering the aggregate Northern cod stock by way of illustration, we reject the hypothesis of strong compensation estimated by the conventional regression methods used by classic bioeconomic models.

Parallel collapses of Canadian cod (Gadus morhua) and European hake (Merluccius merluccius) fisheries: "Chronicle of a death foretold"

Creator:

Agundez, Jose A. and Brethes, Jean Claude

Abstract:

Setting aside the traditional simplistic “tragedy of the commons” notion, fisheries crises observed in the Northern Atlantic may be seen as the result of “mismatches” in the decision making process. The collapse of two fisheries, Atlantic Cod (Gadus morhua) in Canada and European Hake (Merluccius merluccius) in Europe, illustrate the...
