The blood clam has been cultured widely along the coasts of south China, especially the Zhejiang and Fujian Provinces.
In this study, the first genetic linkage map of the blood clam was constructed based on 50 newly developed SSR markers and 534 polymorphic loci identified from 65 AFLP primer combinations among 109 Fl progeny of a full-sib family, as a basic infrastructure for the genetic improvement of blood clam.
For SSR markers, a total of 100 primer pairs from EST sequences of blood clam were screened.
Several EST libraries are under construction in our laboratory, and it is expected that more genie microsatellite (EST-SSR) and SNP markers will be discovered for a complete genetic linkage map in blood clam.
Although morphologically distinct, sex chromosomes have not been found in blood clam, and a sex determination factor or sex determination system remains unclear, the recombination rate was more restricted in the male than in the female among the blood clam in this study.

The normal shape of the erythrocytes of the bivalves known as blood clams is maintained by a marginal band (MB) of microtubules.
10), a finding consistent with previous studies showing that the MB is required for the erythrocytes of dogfish and blood clams to resist deformation caused by mechanical and osmotic stress (Joseph-Silverstein and Cohen, 1984, 1985).
The act of obtaining hemolymph by syringe or by tissue cutting may initiate similar wound-repair mechanisms in blood clams, with elevation of [Ca.sup.++] by entry of seawater a possible trigger.
