摘要: This study evaluates the effectiveness of a 200-kHz inverted echo sounder for monitoring abundance and behavior near-surface zooplankton fish. Data from both oceanic littoral environments are examined: first an 81-day deployment at Ocean Station Papa (OSP) in northeast Pacific during spring 1996, second 8-day southern Strait Georgia September 1998. The analysis combines calibrated backscatter intensity, echo-amplitude statistics, acoustic-scattering models to produce estimates mean scatterer size abundance. identity various classes is deduced local net trawls reference previous studies. At OSP site dominant scatterers were found be euphausiids, pteropods, myctophid fishes, with lengths 15, 1.5, 28 mm, respectively. three fish identified: juvenile herring length near 10 cm, salmon o...
