Individuals that appeared to have given birth in the current year were classified as postpartum, and those that had given birth but not recently were considered to be in a resting stage
. A recently postpartum specimen was characterized by the presence of flocculent material consistent with portions of nutritive capsules along with milky uterine fluid (Gilmore et al., 2005); the uteri of a postpartum fish are very flaccid, and trophonemata are present (Natanson and Gervelis, 2013).
The July temperature averaged 13.0 (SD[+ or -]2.14) in 2008 and 11.3 (SD[+ or -]2.21) in 2009, when almost all of the oysters were in the resting stage
Viability of phytoplankton resting stages
in the sediments of a coastal Swedish fjord.
Many algal species spend part of their life cycle at the sediment surface, either as vegetative cells or in resting stages
. Individuals are then recruited to the pelagic (open water) part of the population.
Consequently, the gonad in the resting stage
following spawning must contain primary tubules as well as secondary tubules that will develop into the fecund tubules for the next reproductive season.
5), presented spawning (S3) stage in January (100%) and March (50%); the reproductive resting stage
(S5) occurred in May (60%), June (75%) and July (67%) 2014.
The presence of ovaries in fish classified in the resting stage
and collected during the main spawning peak of the Patagonian stock was taken as evidence of SS in female Argentine hake (Macchi et al., 2016).
* Resting stage
(stage 0): preceded the gametogenesis stage or occurred after a massive spawning event with resorption of gonadal cells.
plumieri , where it was observed cells in vitellogenesis even in the smallest individuals, only females in resting stage
showed this pattern.
In the resting stage
, the vagina is a collapsed tube, and without an erection that's how it will stay.
When times got tough for the fossil myxobacteria or they wanted to disperse their spores, says Lanier, some of the cells collectively formed a protective structure called a sporangiole, which housed myxospores, or cells in their resting stage
. Later, the sporangioles burst, and the released myxospores glided in groups toward the walls, where they germinated into rod-shaped vegetative cells.
This study revealed that the only evidence of skipped spawning observed for Argentine hake was the resting stage
. Analysis of 58,891 adult females of Argentine hake sampled during their reproductive peak indicates that, annually, between 6% and 22% of them had skipped spawning.
