Environmental DNA for Aquatic Monitoring: Impact of Diel Vertical Migration
Environmental DNA, Volume 7, Issue 5, September–October 2025.Environmental DNA concentrations are affected by animal behavior, such as diel vertical migration (DVM), which has repercussions for designing eDNA sampling strategies. The effect of DVM was identified for hake using samples from the Bay of Biscay and corroborated using theoretical Lagrangian particle‐tracking modeling.

The status of the ocean shrimp resource and its management [PDF]
, 1973 The fishery for ocean shrimp (Pandalus jordani) was began in the early 1950's after exploratory fishing by the Department of Fish and Game discovered five dense concentrations. The fishery has been fully regulated since its beginning and is currently

Oceanic cephalopod distribution and species diversity in the eastern north Atlantic. [PDF]
, 2006 This work provides a baseline against which we might measure future changes to oceanic midwater cephalopod stability in the eastern North Atlantic It records a considerable sampling effort from 1959 to 1986 aimed at oceanic midwater cephalopods made by

Static characteristics of a midwater trawl net using canvas mouth opening devices.
NIPPON SUISAN GAKKAISHI, 1988 Amidwater trawl net using canvas sheet outside the wings in place of the otter boards was designed, and the static characteristics of the model net were examined in a circulating water tank within flow speed ranging from 25 to 110cm/s. The width and height of the mouth opening and the total drag of the 1.3m model net were measured varying the canvas ...

Zooplankton biomass in the ice-covered Weddell Sea, Antarctica [PDF]
, 1991 Zooplankton was sampled by a Rectangular Midwater Trawl (RMT 1 + 8) in Weddell Sea surface waters (0 to 300 m) between 66 and 78°S during austral summer (February – March 1983). Sixty-nine taxa including different developmental stages were considered and
