Population dynamics of the Devils Hole pupfish

A model is constructed to simulate fluctuations in monthly population sizes of the Devils Hole pupfish between January 1973 and August 1976. A variety of biological parameters is estimated, and adult mortality is partitioned into natural and environmentally-dependent components. The simulations capture the seasonal fluctuations in population size, and only seven predicted population sizes differ from those observed by 20% or more. The model is used to make testable predictions about the life history of this species and interactions of the parameters are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42634/1/10641_2004_Article_BF00002582.pd

Status and trends of the major roundfish, flatfish, and pelagic fish stocks in the North Sea : Thirty-year overview

Changes in the status of the major roundfish, flatfish, and pelagic stocks in the North Sea over the past 30 years are reviewed. Synopses are presented on trends in catches, fishing mortality, spawning-stock biomass, and recruitment for eight stocks (cod, haddock, whitting, saithe, plaice, sole, herring, and mackerel), together with an evaluation of the current state of these resources and the most recent management advice provided by the ICES Advisory Committee on Fishery Management
