Record #129533:

Ein einfaches Produktionsmodell für die westgrönländischen Fischbestände / H.-J. Rätz.

Title: Ein einfaches Produktionsmodell für die westgrönländischen Fischbestände / H.-J. Rätz.
Translated title: A simple production model for the West Greenland fish population.
Author(s): Rätz, H. -J.
Date: 1994.
Language: German.
In: Informationen für die Fischwirtschaft. (1994.), Vol. 41(1) (1994)
Abstract: Increasing changes in productivity of West Greenland fish population, which in recent past led to considerable losses in production, appear essentially in recruiting processes of cod and fishery activity to be controlled. Multiplicative production model, which alone is based on number of three-year recruits and traced fishery expenditure, clears up 87% of measured variability and predicts for 1994 by minimum expense at lowest level stagnating population.
