Mussel Beds

The effect of changes in particle size and sediment depth on byssal attachment was assessed in laboratory experiments. Mytilus edulis did not attach byssus pads to mud or silt less than 0·85 mm in diameter, but did attach pads to gravel. On gravel more pads were attached to the substrate (mean = 19·44 threads/mussel/week) than to other mussels in the group (mean = 7·34 threads/mussel/week). Because no byssal attachment to the finer substrates occurred and preference for other mussels in the groups rather than the plastic of the holding tank was shown, clumps, characteristic of mussel beds in the field, were formed. The clumps became increasingly well defined as the depth of the substrate increased. Few clumps were formed on the coarsest substrate as a result of preferential byssal attachment to gravel particles.

Passamaquoddy Bay

The distribution of the sea mussel beds of the Passamaquoddy bay area is almost exclusively intertidal. The experiments herein reported show that mussels grow most rapidly when constantly submerged. Their general absence below the low tide level, therefore, is attributed to the particular abundance in this region of the predatory fauna.

The purpose of this study was to localize the red neuronal pigment in Mytilus edulis and examine its role in the control of lateral ciliary activity in the gill. The visceral ganglia (Vg) in the central nervous system show an over al red pigmentation. Most red pigments examined in squash preps and cryostat sec tions were localized in the neuronal cell bodies and proximal axon regions. Unstained cryostat sections showed highly localized patches of this pigment scattered throughout the cells in the form of dense granular masses about 5-7 um in diameter, with the individual granules ranging from 0.6-1.3 um in diame ter. Tissue stained with Gomori's method for Fe showed bright blue granular masses of about the same size and structure as previously seen in unstained cryostat sections.Thick section microanalysis (Fig.l) confirmed both the localization and presence of Fe in the nerve cell. These nerve cells of the Vg share with other pigmented photosensitive cells the common cytostructural feature of localization of absorbing molecules in intracellular organelles where they are tightly ordered in fine substructures.
