Modelling the acoustic effect of swimbladder compression in herring
Summary Analytical expressions describing the fish-backscatteringcross-section, averaged over various geometrical and bio-acoustic parameters, have been obtained. Employing thesesolutions, the… Expand
Acoustic backscattering by Atlantic mackerel as being representative of fish that lack a swimbladder. Backscattering by individual fish
- N. Górska, E. Ona, R. Korneliussen
- Biology
- 2005
Developing acoustic methods for the identification of fish remains a long-term objective of fisheries acoustics. The accuracy of abundance estimation may be increased when the acoustic-scattering… Expand
Modelling the effect of swimbladder compression on the acoustic backscattering from herring at normal or near-normal dorsal incidences
Inaccuracy in herring target strength can be an important source of bias in the acoustic assessment of several important herring stocks. New acoustic data on herring target strength (Ona et al.,… Expand
Acoustic backscatter by schools of adult Atlantic mackerel
- N. Górska, R. Korneliussen, E. Ona
- Geology
- 1 September 2007
The extent of acoustic backscatter by schools of adult Atlantic mackerel (Scomber scombrus) is investigated to improve biomass estimates. Previous studies involving modelled scattering from… Expand
On the target strength of Baltic clupeids
- S. M. M. Fässler, N. Górska
- Biology
- 1 July 2009
The acoustic backscattering of Baltic clupeids, herring and sprat, is explored to improve biomass estimation of these ecologically and commercially important species. Modelling approaches that… Expand
Statistical analysis of acoustic echoes from underwater meadows in the eutrophic Puck Bay (southern Baltic Sea)
- J. Tegowski, N. Górska, Z. Klusek
- Geology
- 1 July 2003
In order to monitor the recovery of vegetation from pollution and the success of re-seeding efforts, acoustic echoes from the sea floor, covered and uncovered by underwater vegetation, were collected… Expand
Some aspects of sound extinction by zooplankton.
To address the importance of sound extinction (or the shadowing effect) in the presence of a densely aggregated zooplankton layer, acoustic scattering by weakly scattering fluid objects is studied… Expand
On acoustic multi-frequency species identification and separation of Atlantic mackerel, Norwegian spring spawn herring and Norway pout.
- N. Górska, E. Ona, R. Korneliussen
- Biology
- 2004
The accuracy of the multi-frequency species identification and separation algorithms may be significantly improved when the detailed acoustic scattering characteristics of the fish are known,… Expand

Study of swimbladder morphometry of baltic herring and sprat (development of measurement methodology)
- J. Idczak, N. Górska, B. Arciszewski
- Environmental Science
- 2011
Effective management of Baltic clupeids, which are valuable commercially and ecologically, requires the biomass control. The acoustical techniques are recognized as effective in fish stock… Expand
