In molluscs, the neurotransmitter serotonin (5-HT) has been linked to a variety of biological roles including gamete maturation and spawning. The possible involvement of 5-HT in abalone gamete release was demonstrated by a dose-dependent increase in Haliotis rubra gonad contractile bioactivity following 5-HT stimulation. Physiological functions associated(More)
Immunohistochemistry was used to identify the distribution of both APGWamide-like and RFamide-like peptides in the central nervous system (CNS) and ovary of the mature female giant freshwater prawn, Macrobrachium rosenbergii. APGWamide-like immunoreactivity (ALP-ir) was found only within the sinus gland (SG) of the eyestalk, in small- and medium-sized(More)
Morphology of the differentiating spermatogenic cells of the rock oyster Saccostrea forskali (Bivalve: Ostreidae) was investigated by light and transmission electron microscopy. The testis is formed by several branching acini containing developing spermatogenic cells, classified into 7 stages based on nuclear characteristics, patterns of chromatin(More)
