Male and female reproduction in penaeid shrimps

This chapter shows that the term “shrimp” is synonymous with “penaeid shrimp” and the new species names will be used even when referring to older literature. The importance of the gelatinous layer to captive breeding is greater than one may initially assume. The grave problem faced by an imminent spawner is that the eggs must separate from each other upon spawning in order for the egg reaction to proceed successfully. The traditional hypotheses on the reasons for the penaeid female reproductive arrest in captivity and the treatments that were used by various authors in tackling this problem are clearly reflected in the literature. The eyestalk sensory pore is a special structure referred to by various authors as the X-organ sensory pore, sensory papilla, or sensory tubercle complex. When compared to pleocyemata species, penaeid shrimp generally seem to have a lower degree of sexual dimorphism.
