The Influence of Temperature - Food Availability on the Tissue Growth of Sea Scallop Placopecten magellanicus
Abstract: A study of the
growth of the sea scallop, Placopecten magellanicus, under suspended culture
conditions was carried out over a seven month period at a culture site in
Graves Shoal, Mahone Bay,Nova Scotia – Canada. Scallop spat were cultivated in
pearl nets at a density of 30-35 per net set at four locations corresponding to
the surface (7 m) and bottom (14 m) at the outer edge and the center of the
site. Whole tissue weight was measured at monthly intervals. Environmental
conditions represented as temperature and food availability at the surface and
bottom over the same period were also monitored. The result showed that the
mean values of whole tissue weight at the surface sites were greater than that
at the bottom sites, but there were not significantly different between the
outside sites and the inside sites. Growth in whole tissue weight was not to
correlate to temperature - food availability.
