Only animals that tested positive were used for the assessment of CsRV1 infection in the eyestalk
ganglia because this required sacrifice of the animal and loss of potential broodstock.
In the case of the eyestalk
, it should be pointed out that the three CA presented an initial increase, although not significant for norepinephrine, followed by different oscillating patterns depending on the particular CA.
As with other species [3,20-22] the eyestalk
ablation was found to be the best technique in the maturation and spawning of the pacific white shrimp L.
Reproduction of Penaeus kerathurus using eyestalk
Ten individuals were randomly divided into two groups, one group for eyestalk
ablation (bilateral ablation) and the other group for ecdysone injection (0.5ug/g).
On the other hand, endogenous dopamine showed to have an in vitro stimulatory effect on the secretion of the gonad-inhibiting hormone (GIH) by the eyestalks
of the crab Chasmagnathus granulata, such effect being abolished by the addition to the incubation medium of the dopaminergic antagonist spiperone (Zapata et al.
The initial volume ran 106 pages and carried nine articles on topics ranging from the effects of eyestalk
ablation on molting, growth, reproduction, and energy budget of Macrobrachium nobilii; leguiminous seeds as protein sources for milkfish, and maintenance of genetic quality in cultured tilapia, to parasites of wild and diseased young cultured golden snappers in Malaysia, aspects of reproductive biology of stolephorid anchovies in Papua New Guinea, and experimental culture of Penaeus semisulcatus, P.
The siphonal canal is a notch-like extension of the aperture through which the left eyestalk
often protrudes in a non-sedated animal.
In this study, we generated the whole transcriptome of Penaeus penicillatus from four combined tissues (eyestalk
, muscle, intestinal and viscus) using High-seq sequencing technology.
Hypertrophy of the AG was induced by bilateral eyestalk
ablation (Khalaila et al., 2002).
SERCA transcript abundance in Y-organs was assessed by quantitative PCR after eyestalk
ablation, and during a natural molting cycle.
