We studied the locomotion and behavior of Dosidicus gigas using pop-up archival transmitting (PAT) tags to record environmental parameters (depth, temperature and light) and an animal-borne video package (AVP) to log these parameters plus acceleration along three axes and record forward-directed video under natural lighting. A basic cycle of locomotor behavior in D. gigas involves an active cli...

Thyroid hormones (THs) play important roles in development, metamorphosis, and metabolism in vertebrates. During the past century, TH functions were regarded as a synapomorphy of vertebrates. More recently, accumulating evidence has gradually convinced us that TH functions also occur in invertebrate chordates. To date, however, TH-related studies in non-chordate invertebrates have been limited....

Assessing the potential biomass yield is a key step in aquaculture site selection. This challenging, especially for shellfish, as growth rate depends on both trophic status and water temperature. Individual ecophysiological models can be used mapping shellfish coastal areas, using input spatial time series of remotely sensed SST chlorophyll-a. approach was taken here to estimate developing oyst...

Studies investigating microplastics (MPs) in marine species have been published over recent decades, including studies on depuration efficacy aquaculture products. This preliminary study investigates the of MPs two commercial oyster from Ireland. The innovative aspects are sampling size (n = 50 per species) and experiment duration (up to 96 h). case organisms Pacific (Magallana gigas) European ...

The shell biosynthesis of oysters plays a critical role in protection against environmental stress, which cartilage matrix proteins (CMPs) determine the mineralogical and crystallographic properties shell. In present study, protein (designated as MgCMP1) was identified from Pacific oyster Magallana gigas (Crassostrea gigas) with objective understanding its possible formation. open reading frame...

Habitat forming ecosystem engineers play critical roles in structuring coastal seascapes. Many engineers, such as seagrasses and epifaunal bivalves, are known to have positive effects on sediment stability increase protection resilience. Others, bioturbating infaunal may instead destabilize sediment. However, despite the common co-occurrence of bivalves seascapes, little is their combined dynam...

The European flat oyster ( Ostrea edulis ) is an important keystone species in Scottish coastal waters. However due to anthropogenic pressures, significant reductions beds have been observed across Europe. In Scotland, several projects are currently aiming restore habitats through the translocation of juvenile oysters from various sources including hatcheries and aquaculture. However, shellfish...

Plastic is currently used in aquaculture as a material for settlement and magnification of oyster spats. weathering fragmentation under natural conditions can lead to the production micro nanoparticles additive leakage, with potential toxic effects on marine life. This study investigates exposure microplastic (MPs) cocktail derived from aged pediveliger larvae (Crassostrea gigas). The was made ...
