“…The M. edulis bivalved shell closes to protect the organism against predation and desiccation under changing intertidal estuarine environments. Phenotypic plasticity of shell shape and morphology has been used previously to compare functional morphology between Mytilids, Crenomytilus grayanus, Mytilus coruscus, and Modiolus modiolus, in varying spatial coastal distributions relating to changing environmental factors (Vekhova 2013). The shell shape and sculpture of freshwater mussels have been explained by hydrologic variability (Hornbach et al 2010).…”

“…Morphological shell plasticity in the freshwater snail Radix balthica was induced by the presence of predators, resulting in a more rotund shell with a low spire for increased survival against shell crushing predators (Br€ onmark et al 2011). It appears that shell shape plasticity can change with environmental conditions and may be a good indicator of environmental change related to shell function (Hornbach et al 2010;Peyer et al 2010;Br€ onmark et al 2011;Vekhova 2013). Ocean acidification reduces the ability of M. edulis to produce proteins for biomineralization, impacting shell growth (Fitzer et al 2014b).…”

Ocean acidification threatens organisms that produce calcium carbonate shells by potentially generating an under‐saturated carbonate environment. Resultant reduced calcification and growth, and subsequent dissolution of exoskeletons, would raise concerns over the ability of the shell to provide protection for the marine organism under ocean acidification and increased temperatures. We examined the impact of combined ocean acidification and temperature increase on shell formation of the economically important edible mussel Mytilus edulis. Shell growth and thickness along with a shell thickness index and shape analysis were determined. The ability of M. edulis to produce a functional protective shell after 9 months of experimental culture under ocean acidification and increasing temperatures (380, 550, 750, 1000 μatm pCO 2, and 750, 1000 μatm pCO 2 + 2°C) was assessed. Mussel shells grown under ocean acidification conditions displayed significant reductions in shell aragonite thickness, shell thickness index, and changes to shell shape (750, 1000 μatm pCO 2) compared to those shells grown under ambient conditions (380 μatm pCO 2). Ocean acidification resulted in rounder, flatter mussel shells with thinner aragonite layers likely to be more vulnerable to fracture under changing environments and predation. The changes in shape presented here could present a compensatory mechanism to enhance protection against predators and changing environments under ocean acidification when mussels are unable to grow thicker shells. Here, we present the first assessment of mussel shell shape to determine implications for functional protection under ocean acidification.

Bivalve mollusc M. galloprovincialis is one of the most common marine animals in the Azov‐Black Sea basin. The shell length increment of mussels is indicators of the degree of favourable environmental. The aim of the study the individual growth of M. galloprovincialis mussel in various habitat conditions. To determine the individual growth of mussel, a labelling technique was used. 50 individuals of one‐sized 35 and other sized 60‐mm mussels were placed into separate sectors of two oyster cages. One cage was hung out in the clear water area of a mussel–oyster farm, the second in a polluted apex part of the harbour. Mussels with a shell length of 35 mm from the mussel–oyster farm were 6 times higher in the shell length increment than mussels from harbour, in the size group of 60 mm were 3.5 times higher. In the studied water areas during the experimental period, the growth of mussels of the two size groups was uneven. In adverse harbour conditions, mussel growth slowed down, stopped and sometimes had ‘negative growth’ values were noted. The shell length increment of mussels was influenced by the ecological state of the environment (pollution), nutritive base, reproductive state and hydrodynamic regime of the compared water areas. The shell length increment of M. galloprovincialis reflects the adaptation of mussels to a complex of environmental factors and can be used as a one of the parameters of bioindication of water areas.
