Eyestalk, ablation

Factors from the eyestalks of H americanus, specifically cHH, have been implicated in playing a role in osmoregulation too [132]. The involvement of cHH in osmoregulation was confirmed in another decapod crustacean, viz in the crayfish Astacus leptodactylus, where the injection of cHH into eyestalk-ablated specimens caused a significant increase in the haemolymph osmolality and Na+ concentration, whereas the concentration of Cl remained unchanged [133]. [Pg.103]

Fig. 21.4 Effects of eyestalk ablation on lobster growth. The larger animal (upper) had both of its eyestalks removed 2 months after hatching. The intact control animal (lower) was its full sibling. Both lobsters were kept in the same aquatic system for 1 year and fed excess amounts of food. From Conklin and Chang (1983)... Fig. 21.4 Effects of eyestalk ablation on lobster growth.

In addition to its effects on the molt interval previously described, there are observations that MF is a female gonadotropin. Early, indirect studies involved eyestalk ablation and subsequent ovarian maturation. For example, MOs (the... [Pg.421]
