Etude comparative de l'ultrastructure des glandes androgènes de Crabes normaux et pédonculectomisés pendant la vie larvaire ou après la puberté chez les espèces: Rhithropanopeus harrisii (Gould) et Callinectes sapidus Rathbun

Neuroendocrine control of reproduction in the male penaeid prawn, Parapenaeopsis hardwickii (Miers) (Crustacea, Decapoda, Penaeidae)

“…Therefore, it is suggested that the eyestalk hormone has inhibitory influence and brain and thoracic ganglia hormones have stimulatory influence on the secretory activity of the androgenic gland. Results similar to those obtained in our study were also report-D E ed earlier in S. serrata (Rangnekar et al, 1971); R. harrisii and C. sapidus (Payen et al, 1971) and L. seticaudata (Touir, 1973) in which it was suggested I and % of total that the ablation of eyestalks leads to a hypertrophy and testis of P.…”

“…Later, Demeusy's results were supported by Otsu (1963) in Potamon dehaani, Rangnekar et al (1971) in Scylla serrata, Ryckaert et al (1974) in Palaemon serratus. Rangnekar et al (1971) on S. serrata, Payen et al (1971) on Rhithropanopeus harrisii and Callinectes sapidus and Touir (1973) on L. seticaudata have emphasized that in these crustaceans the eyestalk removal tends to an increase in the activity of androgenic gland as evidenced by hypertrophy and hyperplasia of androgenic gland and the increase in spermatogenic activity seems to be a consequence of hyperactivity of androgenic glands.…”

Cloning and expression of mRNA encoding prepro‐gonad‐inhibiting hormone (GIH) in the lobster Homarus americanus

“…hypothesis [12][13][14][15]. Furthermore, the striking similarity between crab preproMIH and lobster preproGIH, combined with the possibility that GIH is involved in molt inhibition, indicates that, similar to lobster GIH, crab MIH may play a role in gonad growth.…”

Déroulement des gamétogenèses chez les CrabesCarcinus maenas(L.) etC. mediterraneusCzerniavsky parasités par la Sacculine

“…Ces amas renferment des flaques correspondant probablement a des lipides; de telles enclaves lipidiques ont ete remarquees a 1 'echelle ultrastructurale chez C. maenas porteur de Sacculine externe [27]. 11 est interessant de rappeler que la presence de liposomes dans les glandes androgenes de Crabes a ete egalement decelee dans des conditions particulieres: apres }'ablation des pedoncules oculaires chez les larves de divers Crabes [28,29] et lors de cultures in vitro [27].…”
