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...

Introduction/purpose: In this study, we investigated the possibility of removing organophosphorus pesticide malathion from water using a new adsorbent based on biowaste river shell shards Anodonta Sinadonta woodiane family, material that accumulates in large quantities as waste banks rivers. Two adsorbents were tested - mechanically comminuted shells (MRM) and mechanosynthetic hydroxyapatite (R...

To complete their life cycle, freshwater mussels of the order Unionida depend on fishes as hosts for obligatory parasitic larval phase, glochidium. Here we report first documentation gobioid glochidia unionid in wild Italy and southern Europe (outside Danube drainage area). We also examined pattern attached glochidia. A recent review reported 326 fish species suitable unionids, but only eight (...

Seasonal changes of microcystin (MC) bioaccumulation in three freshwater Unionid bivalves, Anodonta woodiana, Cristaria plicata, and Unio douglasiae, were investigated in the hypereutrophic Lake Suwa. Total MC concentrations (MC-RR and -LR) as determined by reverse-phase high-performance liquid chromatography were at high levels in the hepatopancreas of C. plicata and U. douglasiae, with maxima...

Parasites can negatively affect hosts at individual, population, and species-level scales. However, the link between individual- population-level impacts is often poorly understood. In particular, response to parasitism may alter wider ecosystem dynamics if animals with engineering capabilities are infected. Here, we examine effects of on a freshwater engineer, unionid mussel Anodonta anatina, ...
