chilensis is a partial spawner
which can release up to two masses of eggs per day in a long reproductive season, averaging 621 [+ or -] 458 masses per season.
The fish swam off strongly and, having been carefully handled, it has every chance of making it back to sea and returning to the river in a year or two as a repeat spawner
For the IBI, the individual metrics included number of species (species richness), total fish abundance, and % of lithophilic spawner
Based on a monthly natural mortality rate estimate of 0.53, virtual population analysis was performed to obtain two population indices: (1) snail spawner
virtual abundance (or SS index), and (2) snail recruit virtual abundance (or SR index).
In some cases, the author "became curious about an industry and then worked from there to find the main talent spawners
"; at other times, he "wondered if a prominent person was a superboss and followed up with research" or heard of a "talent spawner
from a protege and decide to map out the industry in depth." Finkelstein's research team conducted more than 200 interviews of potential superbosses and their proteges to collect anecdotes and other evidence for analysis.
Like most of fish species in the family Lutjanidae, the Brazilian snapper is a multiple batch spawner
with asynchronous oocyte development and indeterminate fecundity regulation (Bannerot et al., 1987; Ferreira et al., 2004; Evans et al., 2007; Brule et al., 2010; Freitas et al., 2011; Fernandes et al., 2012).
The diameter and corrected fecundity ranges of Alabama shad are similar to those of the American shad, a known heterochronal spawner
, which could suggest a continuing pattern of heterochronal spawning within the Alosa genus (11).
All of spawner
fish were subsequently kept at out-door circular concrete at a density up to 10 kg/m3.
So when I saw an angler reel in a huge spawner
in the shad zone below the Holyoke Dam last week, I was quite surprised.
lepida is a crevice spawner
like the majority of Cyprinella.
tennesseensis has been presumed to be a nest associate spawner
and has been observed over the nest of Campostoma anomalum (Starnes and Jenkins, 1988; Jenkins and Burkhead, 1994).
