Vertical diel dynamic of fish assemblage associated with an artificial reef (Northern Adriatic Sea)

Scientia Marina, 2007
The vertical diel activity of a fish assemblage inhabiting the Senigallia artificial reef (northern Adriatic Sea, Italy) was evaluated from July to November 1996 using enhanced hydroacoustic techniques. Extensive seabed mapping of the area was done using

Estimating biomass, fishing mortality, and “total allowable discards” for surveyed non-target fish [PDF]

ICES Journal of Marine Science, 2014
Abstract Demersal fisheries targeting a few high-value species often catch and discard other “non-target” species. It is difficult to quantify the impact of this incidental mortality when population biomass of a non-target species is unknown.

The Spatial Variation of Acoustic Water Column Data and Its Relationship with Reef-Associated Fish Recorded by Baited Remote Underwater Stereo-Videos off the Western Australia Coast

Journal of Marine Science and Engineering, 2022
Spatially explicit information on coral fish species abundance and distribution is required for effective management. Nonextractive techniques, including echosounders and video census, can be particularly useful in marine reserves where the use of ...

Large mesopelagic fishes biomass and trophic efficiency in the open ocean [PDF]

Nature Communications, 2014
With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger than the current estimate. Here we combine modelling and a sensitivity analysis of the acoustic observations from the Malaspina 2010 ...
