Hydroacoustic technologies are widely used in fisheries research but few studies have used
them to examine the effects of Marine Protected Areas (MPAs). We evaluate the efficacy of …

Hydroacoustics (2002–04) and long‐term oxygen data (1969–2004) have been used in
conjunction to examine the habitat of Arctic charr in the north and south basins of …

The EU Water Framework Directive (WFD) requires the biological elements of aquatic
ecosystems, including fish abundance, to be monitored. At present hydroacoustic methods …

In shallow waters horizontally aimed transducers are used to maximize usable survey
volume due to the physical limitations of the environment. However, horizontal acoustic …

Diel vertical migration (DVM) in fish has been studied extensively on the population level,
but the individual variability of migration behavior has been widely neglected. However, the …

Fish stock monitoring is an important element for the sustainable management of inland
water resources. A scarcity of data and the lack of systematic monitoring for Lake Trichonis …

The spatial distribution of zooplankton was studied in a boreal lake system. Distribution
patterns were associated with water temperature and depth, abundance of fish, and …

Acoustic scattering from fish and macroinvertebrates was studied in a boreal Finnish lake at
three echosounder frequencies (38, 120 and 200 kHz). Split‐beam transducers with partly …

Hydroacoustic surveys were performed in an oxbow lake (Lake L aojianghe, C hina) along
the Yangtze River. The study took place during the day and night in October 2012 using the …

Lake Bourget (France) provides drinking water and is a place for professional and
recreational fishing. Since the mid 1990s, the lake has been exhibiting blooms of the …
