A comprehensive evaluation of the uncertainty of acoustic-trawl survey estimates is needed to appropriately include them in stock assessments. However, this evaluation is not straightforward because various data types (acoustic backscatter, length, w

Mobile acoustic surveys attempt to map and count aquatic organisms without biasing abundance estimates. Horizontal and vertical movements by target species may influence density measurements and net samples during acoustic surveys. To investigate the

Lavnun Mirogrex terraesanctae have a dual-chambered swimbladder and are the dominant fish species in Lake Kinneret, Israel. Bi-monthly acoustic assessments are used to monitor lavnun abundance but the relation between the amount of reflected sound an

The pelagic fish stock (mostly lavnun, Mirogrex terraesanctae) of Lake Kinneret was assessed using HADAS, a newly developed echo-counting analysis system. Total fish numbers (during Mar–Apr) were estimated to be 61 million in 1987, 218 million in 1

A comprehensive quantitative treatment of acoustic‐trawl survey uncertainty that includes all major components of measurement and sampling error is needed to help specify the level of risk in stock assessment models. Acoustic and trawl sampling err

Most acoustic backscatter models predict echo amplitudes of single or aggregations of fish with single‐chambered swimbladders. Lavnun (Acanthobrama terraesanctae), a planktivorous fish in Lake Kinneret, Israel, possesses a dual‐chambered swimblad
