Western Rock Lobster Management - Options And Issues, Kevin Donohue
Western Rock Lobster Management - Options And Issues, Kevin Donohue
Fisheries management papers
Following the Rock Lobster Industry Advisory Committee meeting of the 3 March 1998 the Minister has advised that his position is that there will be no management changes for the 1998/99 season. The purpose of this paper is primarily to provide information explaining management options and issues for consideration of the long term management of the fishery. The paper is divided into three main sections which detail options that have been identified as having the potential to increase the catch value over the next three years. In the first section, an option for enhancing the catch value by transferring lobsters …

A Strategy For The Future Management Of The Joint Authority Northern Shark Fishery. A Discussion Paper., Tim Bray, Jo Kennedy
Fisheries management papers
This paper discusses the current status of the Joint Authority Northern Shark Fishery (JANSF), and the major issues affecting it. The main aim of the document is to present a seires of recommendations to enable effective future management of this resource. The paper provides a brief introduction to the JANSF, followed by an examination of the resource base of the fishery (primary species, stock distribution and stock assessment).
Effect Of Sampling Errors On Estimates Of Recruitment And Fishing Mortality From Separable Virtual Population Analysis, Emmanis Dorval
Effect Of Sampling Errors On Estimates Of Recruitment And Fishing Mortality From Separable Virtual Population Analysis, Emmanis Dorval
Biological Sciences Theses & Dissertations
Separable virtual population analysis (SVPA) models provide estimates of historical recruitment and fishing mortality from analyzing catch data based on the separability of fishing mortality into age specific-gear selection and yearly mortality. These models assume that the catch is randomly sampled and that sampling error is a random variable with constant variance and mean equal to zero. These models do not account for sampling measurement errors that occur when the catch partitioned by age is not measured on every sampling unit without error, and spatio-temporal errors that occur when the observed catch is not representative of the harvested population throughout …
