Beschreibung

Based on an international symposium and workshop hosted by the University of Hull International Fisheries Institute, this new reference includes expert reviews of the advantages and shortcomings of all current techniques and management strategies used in assessment of freshwater fish stocks worldwide. In addition to the core reports, overview papers present a summary of the current status of our knowledge in each of the major subject areas, with a final chapter appraising present and future perspectives on the concept of stock assessment. All contributions are fully illustrated and referenced. Stock Assessment in Inland Fisheries is likely to become the international, standard reference for all fisheries departments--offering a single source of contemporary and definitive information. Moreover, it is also intended to serve as a course text for students learning about freshwater-fisheries management.

The use of resistivity fish counters in fish stock assessment (M. Aprahamians, S. Nicholson, D. McCubbing and I. Davidson). 4. Evaluation of a low disturbance methods for estimating population densities of juvenile Atlantic salmon (Salmo salar L.) and trout (Salmo trutta L.) juveniles in chalk streams (D.J. Bird, G.W. Lightfoot and A.P. Strevens). 5. Assessment of the deep water trawl fisheries of the South East Arm of Lake Malawi using exploratory surveys and commercial catch data (M. Banda, T. Tomasson and D. Tweddle). 6. Selectivity of Breder traps for sampling fish fry (J. Kubecka). 7. Estimation of migrant yellow eel stock in large rivers through the survey of fish passes: a preliminary investigation in the River Meuse (Belgium) (E. Baras, J-CI, Philippart and B. Salmon). II: Catch Effort Methods. 8. Catch census of coarse anglers in England and Wales (R. Steel, K. O'Hara and P.A. Smith). 9.

III: Hydroacoustic Assessment. 13. Use of horizontal dual-beam sonar for fish surveys in shallow waters (J. Kubecka). 14. Application of a hydroacoustic sampling technique in a large wind-exposed, shallow lake (P.J. Mous, J. Kemper). 15. A hydroacoustic assessment of a rainbow trout (Oncorhynchus mykiss) population in a deep oligotrophic lake (M. Cryer). 16. Stock assessment of the Arctic charr (Salvelinus alpinus) Population in Loch Ness, UK (C.W. Bean, I.J. Winfield and J.M. Fletcher). 17.
