The blue mussel, Mytilus edulis, is a commercially important species, with production based on both fisheries and aquaculture. Dynamic Energy Budget (DEB) models have been extensively applied to study its energetics but such applications require a deep understanding of its nutrition, from filtration to assimilation. Being filter feeders, mussels show multiple responses to temporal fluctuations ...

The sharp-angled (presence of an acute ridge) or rounded (absence of an acute ridge) transition of the ventral and dorsal shell surfaces is the “key feature” for the distinction of Dreissena polymorpha and Dreissena rostriformis. However, up to now it has not been possible to put this into a quantifiable framework. Therefore, the aim of this study was to develop a method, which (i) facilitates ...

Mussel mussels are invasive shellfish whose reproductive potential in the Lahumbuti River is unknown. This study aims to determine seasonal variations reproduction of mussel shells River, Southeast Sulawesi. research was carried out Konawe, Sulawesi 2 periods, namely: May-October 2021 and February-June 2022. The were collected manually using a hand scoop. Furthermore, washed from dirt/soil atta...

Three large and robust shells of freshwater pearl mussel (Margaritifera margaritifera) from Lapland were studied. Internal shell-growth increments, showing annual periodicity, provided information about the ontogenetic age and growth of the mussels. Increment widths generally ranged between 0.4 mm and 30 μm and showed exponential growth trends. Moreover, it was shown that the increment series o...

The M22.8 monoclonal antibody (mAb) developed against an antigen expressed at the mussel larval and postlarval stages of Mytilus galloprovincialis was studied on adult samples. Antigenic characterization by Western blot showed that the antigen MSP22.8 has a restricted distribution that includes mantle edge tissue, extrapallial fluid, extrapallial fluid hemocytes, and the shell organic matrix of...

Sea otters (Enhydra lutris) are keystone predators that consume a variety of benthic invertebrates, including the intertidal mussel, Mytilus californianus. By virtue of their competitive dominance, large size, and longevity, M. californianus are ecosystem engineers that form structurally complex beds that provide habitat for diverse invertebrate communities. We investigated whether otters affec...

Ocean acidification (OA) is occurring across a backdrop of concurrent environmental changes that may in turn influence species' responses to OA. Temperature affects many fundamental biological processes and governs key reactions in the seawater carbonate system. It therefore has the potential to offset or exacerbate the effects of OA. While initial studies have examined the combined impacts of ...

Perna perna (Linnaeus, 1758) is one of the most commercialized mollusk species in Brazil. The individuals with a shell length at least 50 mm are considered to be adults and suitable for commercialization human consumption. However, lack control over size extracted mussels recurrent worrisome issue, which may compromise long-term survival natural stocks. present study evaluated potential differe...

Iatrogenic preterm prelabor rupture of membranes (iPPROM) remains the main complication after invasive interventions into the intrauterine cavity. Here, the proteolytic stability of mussel-mimetic tissue adhesive (mussel glue) and its sealing behavior on punctured fetal membranes are evaluated. The proteolytic degradation of mussel glue and fibrin glue were compared in vitro. Critical pressures...
