Influence of the White Sea sponge Halichondria panicea (Pallas, 1766) on physiological state of the blue mussel Mytilus edulis (Linnaeus, 1758), as evaluated by heart rate characteristics

详细

During laboratory testing it was shown that the presence of the White Sea sponge Halichondria panicea on the shell of the mussel Mytilus edulis negatively affects the functional state of the mollusk as expressed in the increased heart rate recovery time after functional test loads (a 50% water salinity drop for 1 hour). It was found that the degree of this negative influence rises with an increase both in the projective cover of mussel shells by the sponge and in the size/age parameters of mussels.
