Improving aeration for efficient oxygenation in sea bass sea cages. Blood, brain and gill histology

Open Life Sciences, 2016
An air diffusion based system (Airx) was developed to control the dissolved oxygen levels in aquaculture sea cages. The system was introduced and then tested for 37 days in a sea bass sea cage (aerated cage). A second sea bass sea cage, without the AirX,

Hemolymph composition, gene expressions in the gills, and thus the survival of euryhaline crabs are controlled by ambient minor cations according to osmotic condition‐dependent manner

Ecology and Evolution, 2020
Na+ and Cl− are the most abundant dissolved ions in seawater, constituting ~ 85% of total ions. They significantly affect the osmolality of body fluids of marine invertebrates.

Gill infections, gill pathology and gill-related mortality in farmed Atlantic salmon

, 2022
Last year (2021) 54 million Atlantic salmon died at Norwegian food producing sea sites. This constitutes a loss of 15,5% of the fish that were transferred to sea. Gill diseases are among the health issues that causes considerable mortality, economic loss, and reduced fish welfare in salmonid mariculture. The overall aim of the Ph.D.
