Abstract

Previous behavioral observations of Loligo pealeii revealed the potential for multiple paternity within individual egg capsules, each containing 100 to 300 eggs.Five egg capsules, sampled from 3 nearshore locations over 2 yr, were tested for multiple paternity using 3 microsatellite loci.The minimum number of potential fathers was derived from the number of different alleles present in the progeny.All 5 egg capsules exhibited multiple paternity: genetic markers of at least 4 fathers were found in 2 egg capsules; at least 3 fathers were found in 1 egg capsule, and at least 2 fathers were found in the remaining 2 egg capsules.
