Catch-per-unit-effort: which estimator is best?

Miguel Petrere, +2 more
- 19 Mar 2010 - 
TL;DR: The Jackknife approach of the index is recommended, whenever catch is proportional to effort or even under small deviations from proportionality assumption, when a ratio estimator is to be applied and little is known about the underlying behaviour of variables.

Relations between hydrological variables and year-class strength of sportfish in eight florida waterbodies

Timothy F. Bonvechio, +1 more
- 01 Jan 2005 - 
TL;DR: In this article, the authors evaluated how annual and seasonal hydrological variables were related to year-class strength of sportfish across eight Florida waterbodies (four rivers and four lakes).

Application of a surplus production model to assess environmental impacts on exploited populations of daphnia pulex in the laboratory

Alvin L. Jensen, +1 more
- 01 Aug 1982 - 
TL;DR: In this article, the surplus production model is applied to exploited laboratory populations of Daphnia pulex exposed to chronic radiation stress, and the model describes the observed relationship between equilibrium population size and the level of radiation exposure.

The pattern of natural mortality throughout the life cycle in contrasting populations of brown trout, Salmo trutta L.

J.M. Elliott
- 01 Jun 1993 - 
TL;DR: The positive relationship between female density and smolt density indicates a trend towards constant proportional survival at sea and the similarity of sea mortality rates in many year-classes supports this trend.
Journal ArticleDOI

Pre- and post-season tagging models: estimation of reporting rate and fishing and natural mortality rates

William S. Hearn, +2 more
- 01 Jan 1998 - 
TL;DR: Brownie et al. as mentioned in this paper presented a reformulation of their model suitable for pre-and post-season fishery tag return studies and showed that the correlation between estimates of fishing mortality and natural mortality is moderate.
