English

Subject field(s)
  • Marine Biology
  • Crustaceans
  • Aquaculture
CONT

Vitellogenesis in decapod crustacea ... has been shown to be mediated by hormones. ... Female shrimps often do not mature fully, even though maturing eggs can be found in the ovaries. The maturation process seems to be inhibited by a gonad-inhibiting hormone (GIH) ... The ablation (surgical removal) of eye stalks, which have the glands containing the inhibitory hormone, has been shown to accelerate vitellogenesis.

Record 3 2021-10-21

English

Subject field(s)
  • Aquaculture
  • Crustaceans
CONT

Eyestalk ablation is the most common procedure to induce gonadic maturation in commercial hatcheries of penaeid shrimp. In addition to reproduction, other physiological and metabolic processes are affected by removal of the X-organ sinus gland complex located in the eyestalk.

Key term(s)
  • eye-stalk ablation
  • ablation of eyestalk
  • ablation of eye-stalk

Record 4 2021-10-21

English

Subject field(s)
  • Aquaculture
  • Crustaceans
CONT

Unilateral eyestalk ablation has been widely implemented in aquaculture to accelerate the gonadal maturation and consequently increase the seed production of shrimp broodstock ... This technique removes one eyestalk, which hosts the sinus-organ X that produces hormones such as the gonad inhibiting hormone. These hormones are responsible for accelerating maturation and leads to predictable peaks of maturation and spawning that facilitates the setting up of production schedules ... This practice, however, has been associated with high broodstock mortalities and poor-quality offspring ...

Key term(s)
  • unilateral eye-stalk ablation

French

Domaine(s)
  • Aquaculture
  • Crustacés

French

Domaine(s)
  • Paléontologie
CONT

[Chez un Trilobite, ] la «surface visuelle» [est la partie externe du pédoncule oculaire]. Vue en plan, la surface visuelle a la forme d’un croissant à convexité latérale; en coupe, elle apparaît subverticale et plus ou moins bombée.
