| description | Study of the reproductive strategy of crayfish species is of great importance in the
current astacological world. Crayfish are among the largest freshwater invertebrates, and
as keystone species, they are able to regulate the structure of the benthic fauna in the
freshwaters, demonstrating different ecological strategies and life spans ranging up to
20+ years. In order to bring
together the various pieces of information related to this issue, this overview of
published scientific reports was conducted. The majority of crayfish species studied show
sexual dimorphism, with approximately equal numbers of males and females. However, over
some decades numerous observations have been made for a few species that may have
different modes of reproduction, such as hermaphroditism or intersex (e.g. Cherax
quadricarinatus, Samastacus spinifrons, Parastacus virilastacus
and Pacifastacus leniusculus) and parthenogenesis (only
Procambarus fallax f. virginalis). A recent study
showed a new case of parthenogenesis as apomictic parthenogenesis (only Orconectes
limosus). In addition, there are many investigations into the reproduction
biology of crayfish, including using eyestalk ablation or androgenic gland ablation under
various lab conditions and hybridization under natural conditions (e.g. Astacus
astacus X Astacus leptodactylus, Orconectes rusticus
X Orconectes propinquus). There are also some chemical factors
which could possibly affect the reproduction system of crayfish in the wild. |
