The low variability of the control data as reflected in coefficients of variation of 2.3 and 3.3% for females and males, respectively, make it quite easy to detect statistically significant changes in the mean CTMax of spawned
Cross-spawning effects exist not only because the strategic project spawns
investment opportunities into the operating project, but also because there is a feedback mechanism from the operating project to the investment opportunities into the strategic project.
In large reservoirs where threadfin and gizzard shad dominate the forage base, some bass remain shallow, holding near vegetation edges, docks, and riprap areas where schools of shad spawn
in vast numbers.
Qualitative histological analysis showed that scallops of different stages of gonad development were present throughout the year, except in October 2011 when all gonads were in the spawn
and recovery stage (Fig.
There is no concise data available regarding spawns
but according to a user called Rathbunkum, there might be many variations in the spawning rates.
We also found that Gulf menhaden are batch spawners that spawn
every 2.1-4.3 days and that although they show indeterminate fecundity, they have several traits typically associated with determinate fecundity.
To decrease chances of polyspermy, males were removed from spawning aquaria once they began to spawn
. Any sperm that had been released remained in the spawning aquaria to fertilize eggs.
Increased number, spawn
rate & the descent speed of Supply Drops.
Mountain Redbelly Dace, Rosyside Dace, and Crescent Shiner frequently spawned
on active chub nests; spawning events for strong associates were regularly documented.
To determine whether larger males were more likely to be guarding eggs than smaller males and whether larger males spawn
earlier in the breeding season, the measured males were divided into four groups based on the presence or absence of eggs and on the date of capture (15 March through 15 April and 16 April through the end of May).
Mature gravid fishes that were ready to spawn
were observed to move slightly in ascending direction to the upper parts of the River.
bovinus aligned in parallel and separated; we chose this metric because it can be difficult to accurately differentiate between a spawn
(egg deposited) and a spawn
attempt (no egg deposited) from video recordings.
Just below the summit of Foel Fras, 3,000ft above Abergwyngregyn in Gwynedd, he came across frog spawn
in a pool.
Lingcod in the exhibit typically spawn
each season between mid-December and mid-March, usually near year-end, using one or more of 3 specific locations.
(In our study, the number of JI per spawn
per female is referred to as actual fecundity.) A sample of 10 JI was taken from each brood, and the cephalothorax length of each juvenile was measured stereo-microscopically from the tip of the rostrum to the posterior end of the cephalothorax.
