Mountains in the Sea: Fishy Deep-sea Designs [PDF]

In this activity, students will focus on adaptations of fishes living in the mesopelagic and bathypelagic zones of the deep ocean. The students will learn about the physical location of deep water habitats along the Hudson Shelf Valley and in Hudson ...

Stranding of Mesopelagic Fishes in the Canary Islands

Animals, 2022
Most mesopelagic fishes perform large diel vertical migrations from the deep-sea zone to the surface. Although there is a trade-off between a higher food availability at the upper layers and an energy cost and predation risk, incursion towards the surface also implies a transport by currents, where the fish are exposed to a stranding risk on the coast.

Running the Gauntlet: Assessing the Threats to Vertical Migrators

Frontiers in Marine Science, 2020
Diel vertical migrations (DVM) by zooplankton and nekton are driven by the selective advantage of avoiding visually cued predators near the surface during the hours of daylight.

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, EarlyView.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Temporal resolution in mesopelagic crustaceans

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Mesopelagic crustaceans occupy a dim–light environment that is similar to that of nocturnal insects. In a light–limited environment, the requirement for greater sensitivity may result in slower photoreceptor transduction and increased summation time.

Solitary phytoplankton cells sink in the mesopelagic ocean. [PDF]

PLoS One
AbstractPhytoplankton, and their carbon, are typically exported from the surface ocean when packaged inside larger, sinking detrital particles. This process draws carbon out of the atmosphere, where it can be sequestered for long time periods in the deep ocean.

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, EarlyView.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate

The Vertical and Horizontal Distribution of Deep-Sea Crustaceans in the Order Euphausiacea in the Vicinity of the DeepWater Horizon Oil Spill

Frontiers in Marine Science, 2020
The vertical and horizontal distributions of Euphausiacea in the northern Gulf of Mexico (GOM), including the location of the Deepwater Horizon oil spill, were analyzed from 340 trawl samples collected between April and June 2011. This study is the first

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology, EarlyView.
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.
