Abstract

Bilateral eyestalk ablation accelerated moulting frequency and weight gain
in juvenile, maturing and mature Panuliriis homarus, irrespective of their reproductive
status. Three- to seven-fold increase in weight gain was obtained on eyestalk
ablation. Ablation also did not incapacitate the lobsters in locating food,
nor did it interfere with regeneration of autotomised limbs. The study indicates
the presence in P. homarus of the Moult Inhibiting Hormone (MIH) and the
Gonad Inhibiting Hormone (GIF) factors in the eyestalk.
