Laboratory spawning of the purple snail Plicopurpura pansa (Gastropoda: Muricidae).

Abstract

Se describe el desove del gasterópodo Plicopurpura pansa (Gould, 1853) (Gastropoda, Prosobranchia, Muricidae) a 22-23°C en el laboratorio. Cada hembra depositó diariamente de 1 a 20 cápsulas por lo menos durante 20 semanas y produjo hasta 150 cápsulas durante la estación de reproducción. Durante el tiempo de desove se formaron agrupaciones de cientos de cápsulas de diferentes edades y diferentes hembras. Cada cápsula contenía, según del tamaño, en promedio 436 embriones (± s.d. 213.6, ámbito: 95-1 092, n=50). Los embriones se desarrollaron sin huevos nutricios. Después de seis a ocho semanas del desarrollo lecitotrófico intracapsular eclosionaron larvas veliger planctotróficas completamente desarrolladas con dos velum de forma lobulada.

The spawning of the muricid gastropod Plicopurpura pansa in the laboratory at 22-23°C is described. Females deposited 1-20 capsules daily for at least 20 weeks, and produced up to 150 capsules each per spawning season. During spawning, egg clusters were formed consisting of hundreds of capsules of different ages deposited by different females. Each egg capsule contained an average of 436 embryos (± s.d. 213.6, range: 95- 1 092, n = 50). Embryos developed without nurse eggs. After six to eight weeks of intracapsular, lecithotrophic development, planktotrophic veligers hatched with two fully developed velar lobes
