2008) reported that male two-spotted gobies Gobiusculus flavescens prefer females with more colorful bellies and this likely signals readiness to spawn
because these populations spawn
synchronously during a restricted period of a few hours in the early night, and sampling time is restricted to just after spawning (Hunter and Goldberg, 1980; Hunter and Macewicz, 1985; Funamoto and Aoki, 2002).
Bass may be weakened and tough to catch directly following a major spawn
, but a week or two later, the fishing just doesn't get any better.
Wheat, rye and millet that are used in making spawn
also belong to this genre .
The present study was carried out with the purpose of optimizing the rate of imazalil sulphate for the treatment of spawn
All were pair spawns
(Figure 1), with the same male involved in all spawns
Sightings of natural spawning, however, are most often chance observations and, as a result, many species that do spawn
synchronously may simply not yet be known to do so.
After spawning the fish are weak and if they are to survive to spawn
again they must be handled very carefully so that they do not become damaged or stressed.
For reasons still unknown, some of these capelin schools spawn
on the offshore banks like the cod, which gorge on them shortly after their orgies are completed.
In the above model, the only source of synergistic growth comes from the feedback mechanism, where projects spawn
each other both ways.
also have been observed in the catastomid Erimyzon oblongus (Page and Johnston, 1990).
The mitochondrial DNA analysis confirmed that multiple females were contributing to individual spawns
over protracted time periods (weeks to months).
Further south in the Chesapeake, this species spawns
from May to September (Chanley & Andrews 1971).
However, spawning in the afternoon is less common and may be linked to large tidal cycles and strong currents in the north of WA, as indicated for the brown stripe snapper (Lutjanus vitta) that also spawns
in the afternoon in the Pilbara region (Davis and West, 1993).
Evidence of mutton snapper spawning tends to support the argument that the species spawns
during a full moon, in contrast to the examples of other lutjanids above.
