2005), only the resting stage
was observed in Argentine hake from the Patagonian stock in our study.
In July of 2008 and 2009, the lowest average temperatures were recorded, and almost all of the animals were in the resting stage
Many of these algae form resting stages
and may rapidly enter the water column at suitable growth conditions.
japonicus completely disappear after spawning, and a condition corresponding to the resting stage
of Tanaka (1958) was not found (Choe, 1963).
2%); however, no samples were collected during the resting stage
In contrast, Carmen, Machona, and Mecoacan oysters presented behavior contrary to those located in the north, where the resting stage
However, the minimum CI values did not coincide with the sexual resting stage
, but were reached in January and February, when the populations were at the stage of advanced gametogenesis (stage 2).
In October, 40-60% of clams were in the resting stage
In the first conditioning experiment, more than 50% of the clams were in the resting stage
(0) when the experiment began, the rest of the clams showed residual gametes and a small percentage (10%) had started gametogenesis (1).
Our data indicate that the gametogenic development of Chinese anapella clams is cyclic and it can be summarized as a resting stage
from January to April, an early active stage from February to May, a late active phase from July to August, maturity or spawning readiness in July and August, spawning or the partially spent stage from August to October, and finally the spent stage from September to December.
He covers sexual reproduction, asexual reproduction and regeneration, cysts and resting stages
, sex determination, sex differentiation, and highlights and directions.
The factors that stimulate the production of resting stages
may act distinctly on different species, and also among different populations within a same species.
