The role of salmonid fishes in conservation of the endangered freshwater pearl mussel (Margaritifera margaritifera)

2016

The abundance of freshwater pearl mussels (Margaritifera margaritifera) has declined widely during the past century, and new conservation initiatives are needed. This thesis focused on the relationship between M. margaritifera and its salmonid host required for reproduction of this species. First, by exposing fish experimentally to glochidium larvae of M. margaritifera, different M. margaritifera populations were shown to demonstrate strong differences in their ability to parasitize different salmonid species. Atlantic salmon was clearly a better host for mussels in large river channels, whereas in small headwater tributaries brown trout was the best, or the only suitable, host. These findi…

Determination Aspects of Possible Purchasing Prices for Blue Mussel Products from the Baltic Sea

2019

Demand for marine products has been relatively high and is increasing in most of countries. With higher demand for higher-value and protein-rich products population is looking for other sources that could be protein-rich products and might be substitute for fish products. Blue mussel contains proteins and minerals therefore it might become as food and feed ingredient and supplement product for food. Experience in many countries world-wide where mussel production is more developed has indicated that important aspect in realisation of the production is effective marketing. The following research methods were used in the research: studies of scientific publications on blue mussel price and fac…

Microscale magnesium distribution in shell of the Mediterranean mussel Mytilus galloprovincialis: An example of multiple factors controlling Mg/Ca in…

2019

Abstract Since magnesium concentration (Mg/Ca) in biogenic calcite is considered to reflect water temperature during precipitation, the magnesium-to‑calcium ratio has been examined as a proxy for water temperature in paleoclimate research, although factors other than temperature may also influence Mg/Ca in biogenic calcite, thereby introducing a potential bias in the relationship between Mg/Ca and temperature observed in inorganic systems. To better understand factors controlling Mg incorporation into the calcitic shells of bivalves, the distribution of Mg in the Mediterranean mussel Mytilus galloprovincialis was studied, being compared with ambient sea surface temperature (SST), shell grow…

Inductively coupled plasma atomic emission spectrometric determination of arsenic in mussel products

1993

A precise, accurate procedure is proposed for the determination of arsenic in mussel products by inductively coupled plasma atomic emission spectrometry. Organic matter is destroyed by dry ashing. Experimental conditions for the determination of arsenic were selected and an interference study was carried out. The methodology developed has a detection limit of 0.1 μg g−1, a relative standard deviation of 3%, and a recovery percentage of 98±2%. The accuracy of the method was checked by analysis of a certified sample of NIST oyster tissue (certified 14.0±1.2 μg g−1; found 14.1±1.1 μg g−1). The proposed procedure was used to analyze real samples of mussel products.

Conservation of the Giant Freshwater Pearl Mussel (Pseudunio auricularius = Margaritifera auricularia Spengler, 1793) in Spain

2023

Las almejas de agua dulce o náyades son uno de los grupos faunísticos más amenazados del planeta. Entre ellos, la almeja gigante del Ebro o náyade auriculada (Pseudunio auricularius, Spengler 1793) es el bivalvo unionido más amenazado de Europa, y la población de la cuenca del río Ebro en España se encuentra en una situación crítica. El objetivo de esta tesis es aumentar el conocimiento científico del estado de conservación actual de la especie en España con el fin de aplicar acciones de gestión significativas para reducir su riesgo de extinción. El descenso de las poblaciones de náyades (Orden Unionida) en la cuenca del Ebro es generalizado, pero la situación en los canales asociados es cr…

Effect of substrate particle size on burrowing of the juvenile freshwater pearl mussel Margaritifera margaritifera

2021

AbstractJuveniles of the endangered freshwater pearl mussel (FPM,Margaritifera margaritifera) live burrowed in stream substrate for the first years of their life. Fine sediments block water exchange within substrate and may cause juvenile mortality and recruitment failure. To better understand the connection between success of juvenile FPM and substrate particle size, it would be important to understand behavioural responses of FPM to varying substrate sizes at this critical life stage. We placed newly detached FPM juveniles in a 7-mm layer of sieved sand sorted into five sizes (< 120, 120–200, 200–250, 250–500 and 500–650 µm) each with 10 replicate dishes, 10 juveniles per dish, with bu…

Deep Sea Mining and the possible increase of metals in the water column: how will echinoderms and mussels respond?

2018

Marine pollution has been increasing as a consequence of human activities. In the near future will start the extraction of minerals from ocean depths, Deep Sea Mining (DSM). However, the impacts at the ecosystem level are still unknown. It is necessary to know the effects to contribute to the creation of rules, laws and mining codes that protect and conserve ecosystems and biodiversity. Sea urchin and mussels represents one of the most important seafood product, but also, a sentinel organism for ecotoxicological studies to assess aquatic environments quality. They are directly exposed to anthropogenic contaminants in their habitat. The aim of this study is to understand the influences of tw…
