Fisheries Management and Ecology > 20 > 5 > 445 - 453

Understanding post‐release dynamics of stocked fish is essential to successful stock enhancement. This study aimed to match existing life history knowledge to optimise productivity of releases of mulloway, Argyrosomus japonicus (Temminck & Schlegel) into an urban estuary. Passive acoustic telemetry was used to monitor the movement of juvenile mulloway in the Georges River, New South Wales, Australia,...

Feeding strategy of the non‐native rainbow trout, Oncorhynchus mykiss, in low‐order Patagonian streams

C. Y. Di Prinzio, M. L. Miserendino, R. Casaux

Fisheries Management and Ecology > 20 > 5 > 414 - 425

The dietary composition and feeding strategy of rainbow trout, Oncorhynchus mykiss (Walbaum), in two low‐order Patagonian streams were studied. Benthic macroinvertebrate availability was estimated in both riffles and pools. Fish stomach contents were examined to determine prey richness and diversity, prey electivity, food‐niche width, and the feeding strategy employed by trout throughout the year...

Effective fishing effort indicators and their application to spatial management of mixed demersal fisheries

A. N. Tidd

Fisheries Management and Ecology > 20 > 5 > 377 - 389

Since the Common Fisheries Policy reform in 2002, there have been various proposals for designing effective input‐management tools in the context of demersal multispecies and multimétier fisheries to augment quota management. The relationship between fishing mortality and effort exerted by the English beam trawl fleet is investigated for two stocks of North Sea demersal fish, plaice, Pleuronectes platessa...

The balancing act of captive breeding programmes: salmon stocking and angler catch statistics

K. A. Young

Fisheries Management and Ecology > 20 > 5 > 434 - 444

The debate over Atlantic salmon, Salmo salar L., stocking in Britain centres on the trade‐off between enhancing rod fisheries and harming wild populations. This article informs the debate by quantifying the relationship between stocking and angler catch statistics for 62 rivers over 15 years. After controlling for environmental factors affecting adult abundance, the 42 rivers with stocking had non‐significantly...

Managing European cormorant‐fisheries conflicts: problems, practicalities and policy

M. Marzano, D. N. Carss, I. Cheyne

Fisheries Management and Ecology > 20 > 5 > 401 - 413

This article focuses on transboundary conflicts between great cormorants, Phalacrocorax carbo L., and European fisheries interests. Two races of this species commonly occur in Europe; the ‘Atlantic’ Phalacrocorax carbo carbo and the ‘Continental’ P. c. sinensis. This migratory fish‐eating bird has steadily expanded its European range and many consider this a nature conservation success. However, fishery...

Evaluation of a river classification system as a conservation measure in the management of Atlantic salmon in Insular Newfoundland

G. Veinott, N. Cochrane, J. B. Dempson

Fisheries Management and Ecology > 20 > 5 > 454 - 459

In an effort to address the decline in abundance of Atlantic salmon, Salmo salar L., in insular Newfoundland rivers, resource managers introduced a River Classification System (RCS) in 1999 to assist in the management and conservation of the resource. The RCS set daily and seasonal bag limits in the recreational fishery on a river by river basis. An analysis of the catch and effort data before and...

Reproductive migration of fish and movement in a series of reservoirs in the Upper Parana River basin, Brazil

S. G. Britto, E. D. Carvalho

Fisheries Management and Ecology > 20 > 5 > 426 - 433

This study evaluates the effectiveness of two fish passes at two hydropower dams (Canoas I and II) in the Upper Parana basin, which form part of a cascade of three reservoirs. Fish from 12 migratory species (3089 specimens) were captured during their ascending, reproductive migration and were tagged with hydrostatic tags. The recapture data (294 specimens over two consecutive years) showed that there...

Baseline demographics of a non‐native lake trout population and inferences for suppression from sensitivity‐elasticity analyses

B. S. Cox, C. S. Guy, W. A. Fredenberg, L. R. Rosenthal

Fisheries Management and Ecology > 20 > 5 > 390 - 400

Management agencies in several western states of the United States are implementing suppression programmes to control non‐native lake trout, Salvelinus namaycush (Walbaum), for the conservation of native species. This study was implemented to ascertain the population demographics of an expanding lake trout population and use those data to construct an age‐structured model to inform suppression efforts...
