| Description
| - Byla studována závislost maximální, minimální a průměrné akustické síly odrazu – target strength (TS)- na délce a hmotnosti těla a objemu plynového měchýře vybraných evropských sladkovodních druhů ryb (kapr, pstruh, cejn, plotice, okoun, ouklej) a to jak v dorso-ventrální tak v horizontální rovině. TS byla měřena vědeckým echolotem pracujícím s frekvencí 120 kHz. Nejdůležitějším parametrem se ukázala být poloha rybího těla ve zvukovém paprsku. Délka těla a druh ryby byly méně důležité, vliv objemu plynového měchýře na velikost TS byl zanedbatelný. (cs)
- The dependence of maximum, minimum and mean target strength (TS), in both horizontal and vertical planes, on the body length, weight and swimbladder volume of European freshwater fish species (trout - Salmo trutta, perch - Perca fluviatilis, bream - Abramis brama, roach - Rutilus rutilus, carp - Cyprinus carpio and bleak - Alburnus alburnus) was studied. TS was measured with a split-beam echosounder operating at 120 kHz. The orientation of the fish towards the transducer was found to be the most important parameter that affected the TS. Body length and fish species were less important and variations in swimbladder volume contributed little. Regression models for TS, length, weight and swimbladder volume were fitted to the data for both individual species and pooled for all species. The side aspect in the lateral plane gave the strongest echo for all fish species except trout. Here the dorso-ventral aspect gave the most strong echoes.
