Abstract

A simple method for artificial insemination of Macrobrachium idella has been developed. Observations on virili ty in different size groups of males have been reported. The insemination procedu re involved extrusion of spermatophores by electrical stimulus and attachment of sperm mass at the receptive area of newly moulted normal and eye ablated females. Manually placed spermatophorcs were retained through spawning. Fertilization was obtained and eggs fertilized in this way, hatched to normal healthy larvae. The exact lime for placement of spermatophores after the pre-spawning moult of female has been worked oul. Further successful spawning could be obse rved for more than one female simultaneously by using whole sperm mass of a single male. Freshly extruded spermalophores and those stored in refrigerated condition (6°q for different lime duration have al so been used in inseminating females artificially with good success.
