Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

The choice of a suitable sampler for benthic macroinvertebrates in deep rivers [PDF]
Both chemical and biological methods are used to assess the water quality of rivers. Many standard physical and chemical methods are now established, but biological procedures of comparable accuracy and versatility are still lacking.

The Mediterranean deep-sea fauna: historical evolution, bathymetric variations and geographical changes [PDF]
The deep-water fauna of the Mediterranean is characterized by an absence of distinctive characteristics and by a relative impoverishment. Both are a result of events after the Messinian salinity crisis (Late Miocene).

Abstract Climate change is currently driving the expansion of oxygen minimum zones (OMZs), areas of the open ocean with consistently low oxygen levels. Changes in temperature, productivity and consequent respiration, and water mass ventilation drive OMZ expansion and contraction with implications for ecosystem function and biogeochemical cycling ...

Modelling diet composition dynamics among North Sea predatory fish using a length-structured partial ecosystem model [PDF]
Multispecies fisheries management approaches must take account of the array of trophic interactions within the ecosystem. Studies of the gut contents of fish stocks in the North Sea show decadal changes in diet composition, as might be expected when the ...

Our framework links policy targets (achieving good ecological status) and actions (nutrient emission reductions) to realized biodiversity benefits. The approach also supports the optimal placement of monitoring sites under different nutrient abatement scenarios.

The Bijagós Archipelago hosts large populations of migratory shorebird species, which spend the non-breeding period of their annual cycle in this area. For this reason, it as caught the interest of ecologists and ornithologists studying these birds. Benthic macroinvertebrates, despite being a major factor in hosting such large concentrations of their ...

Latitudinal Gradients of Species Richness in Marine Benthos: Insights From Japan's Tidal Flat Areas
Latitudinal diversity gradients in species richness were observed in the coasts of Japan. Extensive tidal flats and biogeographical connectivity to the Eurasian Continent may cause the unexpected peak in species diversity at the Kyushu region. Mollusca was the dominant taxonomic group, followed by Malacostraca, Annelida, and other benthic groups ...
