spawning had occurred in July and August,
ovogenesis and growth of ovocytes began
immediately and proceeded rapidly through
October and November and into December.
Proliferation of the follicles through the
connective tissue of the visceral mass occurs
at this time. Thus, animals collected in
January have initiated or may already have
completed the development of many of the
gametes that would normally be spawned
the following August.
In Southampton Water, the condition
(per cent flesh content) of clams declines
more or less continuously following spawning
and any renewed gametogenesis and
growth of gametes in the autumn can only
be occurring at the expense of stored food
reserves. The proliferation and major growth
of the gonad does not occur until the following
spring. Thus, animals collected in
Southampton Water in January (as were
those in experiment 2) have still to undergo
the main period of gonad proliferation
and may be expected, after conditioning
at this time, to release fewer eggs than
Long Island Sound clams collected in January,
or Southampton Water clams collected
in June after the spring increase in condition
has occurred (as were those in experiment
1).
These results are important in indicating
the dependence of egg production on plankton
abundance over the clam beds at some
time previous to the spawning season. In
Long Island Sound this may be the previous
autumn, in Southampton Water the
previous spring. To what extent the number
of eggs produced also depends on con
