Ar. Beaumont et Akm. Abdulmatin, DIFFERENCES IN MORPHOLOGY, SURVIVAL AND SIZE BETWEEN SELF-FERTILIZED AND CROSS-FERTILIZED LARVAE OF MYTILUS-GALLOPROVINCIALIS, Journal of the Marine Biological Association of the United Kingdom, 74(2), 1994, pp. 445-448
The serendipitous detection of a rare hermaphrodite individual of Myti
lus galloprovincialis during the process of spawning in the laboratory
enabled self- and cross-fertilization to be achieved. Self-fertilized
larvae exhibited significantly higher percentages of morphological ab
normality at 3 d, lower survival at 9 d and decreased size at 31 d of
age compared with cross-fertilized larvae. These results are discussed
in the light of equivocal evidence for inbreeding depression in larva
e derived from self-fertilization, full-sib matings and gynogenesis in
other bivalves.
